ATLAS UNI-GRUNT is a deep-penetrating primer based on the highest quality water-based polymer resin dispersion.

Express – very short drying time – depending on temperature and humidity conditions, new layers can be applied to the primed substrate after:
- approx. 15 minutes – for ATLAS adhesive mortars,
- after approx. 2 hours – for self-levelling floors and screeds, wallpapers, paint coatings on cement-lime plasters, silicate hollow bricks and aerated concrete blocks.

Efficient – one canister of ATLAS UNI-GRUNT diluted 1:3 is sufficient to prime the same surface area as 4 canisters of regular READY-TO-USE primer.

Facilitates the application of subsequent layers – paint coatings, adhesives, top finishes and fillers, self-levelling screeds and floors, carpet adhesives, wallpaper adhesives, thermal insulation adhesives for substrates, etc.

Colourless, solvent-free and water-soluble – the product is colourless after drying and does not cause discolouration of the substrate.

Can be applied with a roller, brush or spray.

Maximum substrate reinforcement effect – penetrates the structure of the material, thanks to a very high content of polymer dispersions, reinforces it and binds it in the penetration zone.

Increases the efficiency of paints, finishing coats and adhesives – by sealing the structure of the primed substrate, it reduces the consumption of materials used for the next coat.

Reduces substrate absorbency – prevents excessive water from being drawn out of the product applied to primed substrates: cement-based screeds with or without underfloor heating, various types of plaster, etc.

Uniformity of substrate absorbency – the product applied in the next layer has the same bonding conditions across the entire surface, including areas where local repairs have been carried out.

Increases adhesion to the substrate - guarantees that the applied product achieves maximum parameters (e.g. strength, adhesion, hardness) by preventing moisture absorption by the substrate. Binds loose particles of dust and dirt, as well as dust remaining after sanding and dedusting surfaces.

Designed for application at elevated temperatures - recommended for use between 5 °C and 30 °C, indoors and outdoors.

Very low VOC content – 15 times lower than the requirements for volatile organic compounds.

• Substrate and ambient temperature during application: from +5 ºC to +30 ºC.

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

Plastic containers: 1 kg, 5 kg, 10 kg, 20 kg.
