ATLAS UNI-GRUNT – fast drying priming emulsion
Description:
ATLAS UNI GRUNT PRIMER is an impregnating sealer for priming, manufactured on the basis of the finest quality water dispersion of polymer resins.
The main characteristics
• reinforces absorptive substrates of any type
• high yield, quick-drying
• decreases and unifies substrate absorptiveness
• for application in temperature up to +30°C
• improves bonding to the substrate
• underneath floors and screeds
• underneath adhesives, plasters, top finishes, paints
The main parameters• consumption: 0.05 – 0.2 kg/1 m²
• further work just after 2 hours
Properties
Very short time of drying – depending on temperature and air humidity, ap- plication of next layers on a primed substrate is possible after:
– 15 minutes – for adhesive mortars ATLAS and painting coats on cement-lime plasters, silicate hollow blocks and aerated concrete blocks,
– 2 hours – for floors and self-levelling screeds.
Reinforces top surface of primed mineral substrates – penetrates into material structure, reinforces it and improves its load-bear capacity.
Improves yield of paints, top finishes and adhesives – increases yield of ma- terials used for the next layer application, reduces their consumption by sealing structure of a primed substrate.
Facilitates application of the next layers – painting coats, adhesives, top finishes and fillers, floors and self-levelling screeds, adhesives for carpets, wallpapers, adhesives for thermal insulation etc.
Decreases substrate absorptivity – prevents from excessive water retention from the product applied on the primed substrates: cement screeds with or without floor heating, various types of renders etc.
Unifies substrate absorptivity – owing to the presence of ATLAS UNI-GRUNT, product applied as the next layer has uniform setting conditions on the whole surface, including areas with local repairs.
Bonds non-stable substrates – reduces dust on floors, screeds and plasters. Intended for application at high temperature – recommended for use at tem- perature from 5°C up to 30°C, indoors and outdoors.
Very low VOC content – 15-times reduced content of volatile organic com- pounds in terms of legal requirements.
Transparent, solvent-free and water-soluble – product is colourless after drying, does not cause substrate discolouration.
For application with a roller, a brush or with a sprayer.
ATLAS UNI-GRUNT Priming
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.
