Product description

Substrates primed with ATLAS UNI GRUNT ULTRA have decreased and unified absorptivity, which ensures adhesion of the following layers.
Emulsion penetrates into the substrate, bonds aggregate grains and reinforces primed layer.
Ultra efficiency – one 5 kg packaging of ATLAS UNI-GRUNT ULTRA is sufficient for priming:
- 50 m2 of floor prior to the application of self-levelling mass
- 115 m2 of plaster prior to the application of top coat, installation of ceramic cladding,
- 150 m2 of substrate prepared for painting.
Special pigment contained in product colours the substrate, which enables to control the work progress, while the primer is still wet and when it dries – the colour does not decrease ability for covering of painting coats.

Main properties

    - significantly improves adhesion to the substrate - decreases and unifies substrate absorptiveness - underneath adhesives, plasters, top coats, paints

Main parameters

    Emulsion density: approx. 1,0 g/cm³ Substrate and ambient temperature during work: from +5 ºC up to +30 ºC Further work after priming (depending on substrate type): - after 15 minutes – plasters, silicate hollow blocks, aerated concrete blocks - after 2 hours – self-levelling floors

3 X MORE SAFETY

Go top

Proper substrate preparation is a base for a success of the entire construction project. The use of ATLAS UNI GRUNT ULTRA, a primer consisting very high content of polymeric dispersion, guarantees safety and assurance that the further works will be carried out on substrate:,

- with optimally decreased and unified water absorption,                

- unified absorptivity on entire surface,

- ensuring highest possibly adhesion to the following layers.

USE

Go top

ATLAS UNI-GRUNT ULTRA is a priming agent for various types of substrate (walls, floors, ceilings), for indoor and outdoor use.

For priming substrates prior to the application of floors, installation of ceramic cladding, plastering, floating, wallpapering and painting. 

Depending on type of construction work and place of application, primer should be diluted in compliance with the instruction.

PRIMING

Go top

Substrate preparation

The substrate should be dry, free from dust, dirt, oils, grease and wax. Remove any loose, poorly bonded layers prior to the emulsion application. In case of gypsum plasters, the sediment formed during sanding should be removed.

Emulsion preparation

ATLAS UNI-GRUNT ULTRA is manufactured as an ultra-efficient emulsion, ready for use after dilution in water in the following ratio:

-       1:3 underneath the floor,

-       1:6 underneath the plasters and top coats,

-       1:8 underneath the paints. 

Priming

The emulsion should be applied upon the substrate with a roller, brush, or spraying machine with thin and uniform coat. For the very absorptive and weak substrates, priming should be carried out twice, with wet on wet technology. In case of priming of surfaces underneath the floor. such emulsion should be poured on substrate and distributed evenly without forming puddles. If the substrate is still absorptive after product drying, priming should be repeated.

Surface use

Painting, wallpapering, tiling, etc., can commence when emulsion dries. The primer should form matt surface after drying. Time of drying depends on temperature and humidity conditions:

-       15 minutes – plasters, silicate hollow blocks, aerated concrete blocks

-       2 hours – floors and screeds

CONSUMPTION

Go top

Average consumption of ATLAS UNI-GRUNT ULTRA:

- 0,1 kg/m² underneath self-levelling screeds,

- 0,043 kg/m² underneath top coats, adhesives for ceramic cladding,

- 0,033 kg/m² underneath paints.

In practice consumption depends on substrate absorptivity level.
