Primers

Atlas Aval KT17 - Primer

Fast drying priming and strengthening emulsion.

Atlas Aval KT17 fast drying priming emulsion.

Improves setting conditions of mortars – contributes to reaching their expected technical parameters.
Strengthens surface of primed mineral substrates – permeates the surface, strengthens and improves its load capacity.
Prevents retention of excessive amount of water from the coat applied upon the substrate – limits the substrate absorptiveness.
Unifies absorptiveness of the whole primed surface – the applied layer has similar setting conditions, irrespective of local changes of substrate parameters.
Forms temporary protective layers on floors and screeds – improves floor resistance against dusting, facilitates cleaning (must not be considered as the top finish coat).
Improves the yield of paints, top finishes and adhesives – by sealing the structure of primed surface, it improves the yield of materials used for the execution of the subsequent layer.

PROPERTIES

Very short drying time – finishing coats can be applied just after 2 hours.
Solvent-free – manufactured on the basis of water dispersion of acrylic resin.
Non-saponifiable during application.
Transparent after drying.
Water vapour permeable.
Inflammable – can be used in premises without windows.

SUBSTRATE PREPARATION

The substrate should be dry, free from dust, dirt, oils, grease and wax. Remove any loose, poorly bonded layers before the emulsion application.

EMULSION PREPARATION

ATLAS UNI-GRUNT is manufactured as a ready-to-use emulsion. It must not be mixed with other materials or thickened. It is admissible to dilute it in weight ratio:
- 1:1 for the first priming, in case of double priming of very weak substrates,
- 1:3 in case of priming substrates under ATLAS paints for indoor use.

PRIMING

It is advisable to apply the emulsion upon the substrate in undiluted form, once, using a roller or a brush, with thin and uniform coat. For the first priming of very absorptive and weak substrates, emulsion diluted with water in 1:1 ratio can be used. When the first coat dries, repeat the priming with undiluted emulsion.

SURFACE USE

Painting, wallpapering, tiling, etc., can commence when emulsion dries, i.e. after approx. 2 hours since application. The primer should form matt surface after drying.

CONSUMPTION

The average consumption is 0.05 ÷ 0.2 kg of emulsion for 1m². In practice, the consumption depends on the substrate absorptiveness.

Mapei - Eco Prim Grip

Multi-purpose, ready-to-use bonding promoter primer with a very low emission of volatile organic compounds (VOC) for render, smoothing and levelling compounds and adhesives for ceramic tiles.

Mapei Ireland tile fixing solutions. Eco Prim Grip - multi-purpose tile primer with low VOC.

WHERE TO USE: Multi-purpose, ready-to-use primer for internal and external floors and walls. Eco Prim Grip may be used to improve the bond of all types of cement, gypsum and lime-based plasters on substrates made from concrete, brickwork, vibro-compressed concrete blocks, lightweight blocks and gypsum. Eco Prim Grip is also suitable for improving the bond of adhesives for ceramics, smoothing and levelling compounds on non-absorbent surfaces, such as ceramic, terrazzo and natural stone floors.

SOME APPLICATION EXAMPLES: Application of render on concrete, brickwork, substrates, etc. Application of smoothing and levelling compounds on old ceramic, terrazzo and natural stone floors. Laying ceramic and natural stone floors directly on top of old ceramic floors.

TECHNICAL CHARACTERISTICS: Eco Prim Grip is a solvent-free, primer composed of synthetic resin in water dispersion and selected inert materials with excellent bond strength, resistance to water and ageing. It guarantees a rough keying surface ideal for render, smoothing and levelling compounds, thus ensuring an excellent bond on smooth substrates and substrates with low absorbency, reducing and evening out absorption of water of absorbent surfaces. Once dry, it guarantees a tough bond of any cementitious render on various types of substrate: concrete, lightweight cellular cement blocks, bricks, stone, plasterboard, wood, ceramic, metal, render, gypsum, etc. Eco Prim Grip is a ready-to-use grey latex which is easy to apply using either a roller or a brush. Eco Prim Grip is non-flammable and has an extremely low emission level of volatile organic compounds (VOC). Therefore, the product is considered non-hazardous for those who use the product and final users of the environments where it is applied. It may also be stored without taking particular precautions.

Mapei - Primer G

Water-based synthetic resin primer for treating gypsum or anhydrite substrates prior to installing ceramic tiles or stone material with cementitious adhesives. Primer G has very low emissions of VOC. For general dust suppression and reducing the absorption of very porous substrates. Suitable for use on absorbent substrates only e.g. screed, plasterboard, plaster, plywood.

Mapei Ireland tile fixing solutions. Primer G - water-based synthetic resin primer for plywood, gypsum or anhydrite substrates.

WHERE TO USE: For treating gypsum surfaces prior to installing ceramic tiles. As an anchoring coat for gypsum-based sprayable plasters. To improve the adhesion of smoothing compounds on cementitious or anhydrite and gypsum-based surfaces. To provide uniform absorption in cementitious or gypsum surfaces.

SOME APPLICATION EXAMPLES: Preparing cement-based surfaces prior to smoothing with self-levelling or thixotropic smoothing compounds. Between layers of smoothing compounds once the first coat is perfectly dry. On gypsum plasters prior to smoothing with cementitious products. On anhydrite surfaces prior to applying cement based products. On cementitious renders prior to smoothing with gypsum based products. On gypsum walls as a fixative for wallpaper adhesives. Before installing ceramic tiles with cementitious adhesives on: – gypsum plasters and sprayed gypsum; – pre-cast gypsum panels; – fibrous-gypsum panels; – anhydrite screeds. Treating gypsum walls, chipboard, cement fibre boards, foamed concrete, renders etc. prior to papering or painting.

TECHNICAL CHARACTERISTICS: Primer G is a synthetic resin-based primer which, once applied to any surface, dry to form a flexible, compact, shiny coating which consolidates the surface, where needed. Primer G also improves the of gypsum of smoothing compounds, paint, adhesive for wall paper, adhesive for tiles and mortar for renders. The film of Primer G on the surface of gypsum or cement, prevents any chemical reaction between sulphates and the cement alluminates of gypsum which, in the presence of moisture, leads to the formation of the salt “ettringite’’ which is the cause of the separation of the two elements. Primer G makes wallpaper stripping far easier and decreases the amount of glue used for paperhanging. When used before applying sprayable plasters, Primer G prevents over-rapid absorption of water by the substrate, prolongs workability time and helps prevent shrinkage cracks.

APPLICATION:
As a treatment for ceramic tiles installed on gypsum. Stir the Primer G just before use, spread it uniformly on the surface with a flat brush or roller without diluting it. If the gypsum plaster surface is particularly smooth and glossy, it is recommended to abrade it beforehand. Once it has dried, install the tiles.
As an anchoring coat for gypsum plasters. Dilute Primer G 1:2 with water and stir well; spread uniformly the mix on the surface with a flat brush or roller or spray pump. Apply the sprayable gypsum plaster as soon as Primer G is dry.
As a primer before applying self-levelling compounds and thixotropic smoothing compounds from the MAPEI range on: cementitious substrates: dilute Primer G 1:1 with water; gypsum based substrate: use Primer G neat.
As a primer for wallpaper adhesives dilute Primer G 1:3 with water.
As a primer between smoothing layers dilute Primer G 1:1 with water.

Binder

Atlas - Postar 80 Screed (10-80mm)

Subfloor or floor of 10 to 80mm thickness - the layer thickness depends on the designed floor set. Recommended for quick repairs - fast-setting - rapidly reaches the operating parameters, which makes it possible to shorten the technological intervals and accelerates the application of the next layers: foot traffic is allowed after 3 hours; tile fixing - just after 24 hours.

Atlas Postar 80. Fast setting cement floor

PROPERTIES

Fast drying - the residual moisture content below 2.6% for screed approx. 4cm thick after 24 hours since application (in standard conditions).
Fast setting – rapid strength build up within the first day of setting.
Thick plasticity - mortar consistency makes it easy to spread, float and to form even surface.
Compressive strength: ≥40.0 N/mm² - recommended for any surfaces exposed to medium and high load.
Flexural strength: ≥7.0 N/mm².
Abrasion resistance: ≥9.5 cm³/50cm²
Low linear shrinkage - minimum changes in linear dimensions during screed drying (approx. 0.6mm/rm) limit the risk of cracking.

Forms screed or floor 10 - 80 mm thick - layer thickness depends on the expected structural arrangement.
Recommended for quick repairs – fast setting - rapidly reaches the operational parameters, therefore the technological breaks are shorter and application of subsequent layers quicker: foot traffic just after 3 hours; fixing the tiles - just after 24 hours.
Can form screed for top flooring layers, e.g. parquet, epoxy floors and coats - characterised by high cohesion and resistance to setting forces, which occur within the joint with flooring layer, e.g. during expansion and contraction of wood resulting from the changes of humidity.
Forms floor characterised by high abrasion resistance – recommended for residential housing, warehouses, industrial premises, on driveways, terraces, etc.
Can be installed as screed with heating system – does not require elastifying admixtures, conducts heat well.
Enables forming a slope and repairs of concrete surfaces, stairs, slabs, floors.

TYPES OF FINISHING LAYERS
Ceramic and stone tiles, epoxy screeds and coats, PVC and carpet flooring, parquet, floor panels.

TYPES OF POSSIBLE ARRANGEMENTS

Bonded - thickness 10 - 60 mm – on good quality substrates, e.g. concrete, cement screed (with or without floor heating)
On separation layer - thickness 35 - 80mm – on poor quality substrates, which do not provide appropriate bonding - dusty, cracked, oiled, dirty, very absorbable; separation layer can be made of, e.g. PE foil 0.2mm thick.
Floating - thickness 40 - 80mm – applied on thermal or acoustic insulation layer made of: polystyrene boards of appropriate hardness, hardened mineral wool panels, etc heating – the layer above the heating layer should be min. 35mm thick.

SUBSTRATE PREPARATION

The substrate should be stable, sound and air dry, the method of its preparation depends on actual floor structural arrangement. General requirements for substrates:
cement floors and screeds – min. 28 days old,
concrete – min. 3 months old.

Bonded screed or floor. The substrate must be free from layers which would impair bonding, particularly dust, lime, oils, grease, bitumen substances, paints, weak and loosening pieces of old substrates. Any substrate surface cracks should be widened and dusted. Just before the application of the main mortar layer, the substrate should be moistened with water and contact coat applied. The contact coat can be prepared with one of the following methods:
- with ATLAS POSTAR 80 modified with ATLAS ELASTIC EMULSION in ratio: 1kg of dry mix + 0.12l of water + 0.06l of ATLAS ELASTIC EMULSION,
- with ATLAS ADHER mortar.
The contact coat has liquid consistency and can be applied with a brush. Rub it well into previously moistened substrate. When the contact coat dries, apply another one before the application of the main screed layer ("wet on wet" method).

Screed or floor on separation layer. The separation layer, e.g. PE foil, must be spread tightly, without wrinkles and folded onto the walls (upon the expansion joint strips) at least to the height of the screed.

Floating floor or screed. The insulation boards must be placed tightly with offset edges upon even surface. Place the separation layer upon the boards and fold it onto the wall.

Screed with heating system. The heating installation must be checked and fixed, fill up the pipes of water heating system with water. The screed should be installed with one layer (when the heating installation is firmly fixed). Follow guidelines listed in the project documentation and recommendations of the heating system manufacturer.

EXPANSION JOINTS

Separate floor or screed from walls and other elements within the application area with ATLAS EXPANSION JOINT PROFILES. The size of application area should not exceed:
- 36 m² with sides length up to 6m indoors,
- 5m² with sides length up to 3m outdoors. The expansions joints should also be executed at room thresholds and around load-bearing posts. The existing structural expansion joints should be transferred onto the floor or screed layer.

MORTAR PREPARATION

Pour the mortar from the bag into a container with the suitable amount of water. Mixing ratio: (water/dry mix) approx. 0.08L/1kg or 2L/25kg and mix until homogenous. Mix mechanically with a low speed mixer with a drill for mortars, a flow mixer or a cement mixer. The mortar is ready to use directly after mixing and keeps properties within approx. 30 minutes.

MASS APPLICATION

Carry the works out according to flooring technology. Use wooden or metal battens to keep screed surface even. Place the battens so the screed or floor layer thickness corresponds to the expected one and is in no place lower than the minimum thickness assumed for a chosen structural arrangement (bonded, on separation layer, floating). In order to compact the mass and spread it more precisely, one can vibrate it with a darby or compact with a float. Collect the excessive mortar along the battens with zigzag moves. The application area should be filled and leveled within approx. 30 minutes. The surface can be floated and smoothed after approx. 3 hours.

SCREED DRYING & MAINTENANCE

During application and directly after, protect the installed screed or floor against excessive drying, direct sunlight, low air humidity or draughts. In order to ensure favourable conditions for mortar setting, depending on needs, sprinkle the freshly applied surface with water or cover it with foil. Proper maintenance leads to increase of strength of product but also extends the time of drying. The time of drying depends on the layer thickness and ambient thermal and humidity conditions. The use of screed or floor (foot traffic) can start after approx. 3 hours and full load after approx. 7 days.

FINISHING WORKS

The time of finishing works execution depends on the setting conditions, humidity, type and permeability of the top finish materials and can commence after approx. 24 hours in case of tiling. PVC flooring can be installed when the screed dries fully. Parquet can be installed after approx. 7 days. If in doubt on the actual residual moisture content, carry out appropriate measuring. The residual moisture content should not exceed: 3% - for tiling, 2% - for the application of self-levelling masses or vapour impermeable flooring, e.g. PVC, wooden flooring, epoxy floors. Prime the surface with ATLAS UNI-GRUNT PLUS before fixing the cladding.

CONSUMPTION

The average consumption is 20kg of mortar for 1m² for each 10mm of layer thickness.

IMPORTANT ADDITIONAL INFORMATION

Inappropriate amount of mix water results in deterioration of strength parameters of of floor or screed. Monitor the mass consistency and quality of mixing during screed or floor application.

Higher air humidity or low temperature extend the setting time of screed.

Until the floor heating is fully turned on, temperature should be increased every 24 hours by maximum 2°C till the maximum operation temperature is achieved. The temperature should then be lowered at the same rate until the heating is turned off.

Before the application of PCV flooring apply a smoothing layer made of ATLAS SMS 15 or ATLAS SMS 30.

Tools must be cleaned with clean water directly after use.

Fast-setting - rapid strength build-up enables foot traffic just after 4 hours since the compound application.
Compressive strength: ≥25.0 N/mm².
Flexural strength: ≥7.0 N/mm².
Very low linear shrinkage - minimum changes in linear dimensions during screed drying (≤0.6mm/rm) limit the risk of cracking and loosening of weak substrates (of low cohesion).
Suitable for manual and machine application – can be easily and quickly applied both manually and with machines equipped with helical pumps, therefore high efficiency is reached.

SUBSTRATE PREPARATION

The substrate should be stable, sound and air dry, due to the risk of mass outflow, should keep bath-like shape. General requirements for substrates:

  • cement screeds – min. 28 days old
  • concrete – min. 3 months old

Substrate irregularities (cracks and gaps) should be leveled with ATLAS ZW 330 mortar. Dry, fixed substrate should be dusted and thoroughly primed with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS emulsion and left to dry.

EXPANSION JOINTS

Separate screed from walls with ATLAS EXPANSION JOINT PROFILES. The expansions joints should also be executed at room thresholds and around load-bearing posts. The existing structural expansion joints should be transferred onto the compound layer.

MASS PREPARATION

Machine application – use mixing-and-pumping units with continuous flow of water. It is advisable to use pumps of efficiency 60L/min. Pour the dry mix to the basket in the mixing-and-pumping unit, set the mix water level providing appropriate mass consistency. Proper consistency can be verified with the use of 0.5 liter or 1 liter container. The prepared mix, poured from a 0.5 liter container onto even, non-absorptive substrate (e.g. foil) should form a "patch" of approx. 35÷40cm diameter (for 1.0 liter container - 50÷55cm).

Manual application – pour the mortar from the bag into a container with the suitable amount of water (see Technical Data for ratio) and mix, best with a low-speed mixer with a drill for mortars, until homogenous. Remix after 5 minutes. The mass retains its properties for about 40-50 minutes. Proper consistency should be verified by pouring the mass from 1 liter container onto an even, non-absorptive substrate (e.g. foil). It should form a "patch" of approx. 50÷55cm diameter.

COMPOUND APPLICATION

Before application, the future compound thickness is to be marked (on walls and in the application area), which can be done with, e.g. a level and portable height benchmarks. Pour the prepared mass evenly and continuously up to the desired height, avoid gaps. The application area should be arranged in the way allowing for mass application and de-aeration within approx. 40 minutes. In case of manual application the excessive mass should be raked up towards oneself with a long metal float. Directly after each application area filling, the mass must be de-aerated with, e.g. a spike roller. It is recommended to perform de-aeration in two perpendicular directions just after the mass application.

MAINTENANCE

The freshly applied compound should be protected against excessive drying, direct sunlight, low air humidity or draughts. In order to ensure favourable conditions for compound setting, depending on needs, sprinkle the freshly applied surface with water or cover it with foil. Proper maintenance leads to increase of strength of product but also extends the time of drying. The time of drying depends on layer thickness and ambient thermal and humidity conditions. Foot traffic is possible after approx. 4-6 hours and full load after approx. 7 days.

FINISHING WORKS

The time of finishing works execution depends on the setting conditions, humidity, type and permeability of the top finish materials and can commence after approx. 24 hours in case of tiling.

Fibre-modified, quick drying floor screed mix which offers extra flexibility for use on most interior floor substrates. Our best screed for underfloor heating and covering substrates such as wood which are subject to movement.

Weber Ireland tile fixing solutions. Weberfloor Flex Level quick drying flexible self levelling compound.

Weberfloor Flex Level is a self-smoothing floor levelling compound — often incorrectly referred to as a self levelling screed or self levelling floor compound — which can be tiled onto and is an easy screed for applying onto floor substrates subject to some movement, such as wood or underfloor heating.

Features and benefits:
Extra flexible levelling screed for substrates subject to movement or expansion.
A high performance alternative to a latex self levelling compound.
Low Dust Technology™ reducing the amount of dust expelled during the mixing process.
Suitable for use as a under tile warming and underfloor heating screed.
Quick drying screed — can take light foot traffic or be tiled onto after 1-2hrs.
Coverage of 1.5m² per 25kg bag, when applied at 10mm thickness.

Uses
For levelling:
Cement screeds, concrete slabs and pre-cast elements
Floors with under-floor heating or under tile warming
Wooden flooring (plywood and particle board panels)
Existing ceramic and rigid plastic tiles
Floating floors.

Suitable for covering with:
Tiles
Flexible floor coverings
Parquet flooring.

Constraints: Not suitable for:
Exterior use
Floors with rising damp
Industrial areas
As a wearing surface.

Preparation
Switch off any under-floor heating systems at least 24 hours before application.
Substrates should be completely dry, hard, rigid and clean. Remove any traces of paint, plaster or laitance or other unsound materials. Thoroughly remove all traces of dust by vacuuming. Fill any large deep holes and allow to dry. Localised holes, up to a total thickness of 50mm can be filled with Weberfloor Flex.
Timber should be rigid and strong enough to support the expected load with minimum defl ection, normally at least 18mm thick of a flooring grade and ventilated beneath. Screw wood panels to joists at least every 200 – 300mm to prevent movement and ensure that every board edge is adequately supported by its adjacent board or joists and noggins. Ensure that all joints and cavities in the substrate are protected to prevent leakage.
Priming with Weber PR360 is recommended to improve adhesion, reduce air bubbles, improve the flow of the screed and prevent de-watering.
Weberfloor 4945 fibre mesh should be used to reinforce Weberfloor Flex in critical areas. The mesh should be fixed to the substrate to prevent it floating to the surface during the application of the screed.

Mixing
Do not mix if the temperature is outside of the range +5°C to +30°C. Thoroughly mix 5 litres of clean water per 25kg bag using a slow speed electric mixer (250 rpm) for at least two minutes until a fluid, homogenous paste is obtained. Allow the mix to stand for 2 minutes, then use within 20 minutes. At higher temperatures this time will be reduced. Do not attempt to extend the pot life by the addition of more water

Application
Pour the mix onto the floor and spread evenly with a steel trowel, spatula or spiked roller. Do not apply at thicknesses above 50mm. The product will self-smooth and most trowel marks will disappear. The minimum application thickness for stabilising wooden substrates is 10mm. Weberfloor Flex is not intended as a wearing surface so the final finishing layer should be applied as soon as possible after drying has completed. If it is to be left for prolonged periods of time the surface should be suitably protected. Allow for suitable expansion or control joints in screeds or slabs, by following them through the new topping.

Overlay
Weberfloor Flex is compatible with Weber floor tile adhesives and thin topping screeds. Weberfloor Flex is ready to receive a tiled covering after 1-2 hours. In small residential areas it can be covered directly with a flexible floor covering such as carpet but a thin layer of Weberfloor Level is always recommended.
Weberfloor Flex is ready to receive Weber thin screeds after 1-2 hours (in normal conditions). However the drying time of 24 hours at 5mm thick must be observed before the final floor covering can be applied.
It should not be painted or used without a floor finish.

Drying time
Weberfloor Flex can receive tiles after a drying time of 1 – 2 hours at an ambient temperature of +20°C. If necessary, the surface can be ground after 2 days following application. High humidity of the substrate, ambient temperature and thickness of Weberfloor Flex will have an impact on exact drying times.

Mapei - Ultraplan Renovation Screed

Fibre reinforced self-levelling compound designed for the renovation/refurbishment of existing floor substrates. For use in both commercial and domestic situations. Can be used from 3-40mm on concrete, screed, stone, ceramic, timber (plywood, chipboard, T&G floor boards). Suitable for use with underfloor heating and for encapsulating electric cable undertile heating systems.

Mapei Ireland tile fixing solutions. Ultraplan Renovation Screed self-levelling compound for underfloor heating.

WHERE TO USE: Used for interior levelling, smoothing and infilling differences in thickness from 3 to 40 mm on new or existing concrete, screeds, stone, terrazzo and ceramic tiles, old and new timber floors, floor boards, chipboard panels, plywood, parquet for use in dry locations as an underlayment for floor finishes such as tile, stone, vinyl, carpet and wood flooring. Ultraplan Renovation Screed is suitable where good resistance to loads is required, also for wheelchair traffic and underfloor and undertile heating systems.

Preparation of the Substrate
The substrate should be solid, free of dust, loose particles, paint, oil, gypsum residues or other contamination that could compromise the bond. Timber substrates should be clean and solidly fixed, open joints should be sealed. Cementitious surfaces that are not sufficiently compacted must be removed. Cracks in the substrate should be repaired. The substrate should be primed with Eco Prim Grip prior to the application of Ultraplan Renovation Screed.

Preparing the mix
Pour a 25kg bag of Ultraplan Renovation Screed into a bucket containing 4.25-4.5 litres of clean water and mix with a low speed electric mixer to obtain an homogeneous, self-levelling, lump free mix. Larger quantities of Ultraplan Renovation Screed can be prepared in suitable mixers. After 2-3 minutes of slackening, the mix should then be restirred and then it is ready for use. The amount of Ultraplan Renovation Screed mixed at any time must be used within 20 minutes (at a temperature of +23°C).

Application
Apply in a single coat from 3 to 40 mm in thickness. To minimise aeration a spiked roller may be used. The self levelling properties of Ultraplan Renovation Screed will provide a surface ready to accept all kinds of floor coverings.
