Product description
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, top-coat application, wallpapering and painting.
3 x more safety. 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 absorption,
- unified absorptivity on entire surface
- ensuring highest possibly adhesion to the following layers..

Packaging:
Plastic containers 4 kg
Properties
  • Primed substrates have decreased and unified absorptivity, which ensures better adhesion of the following layers.
  • Emulsion penetrates into the substrate, bonds aggregate grains and reinforces primed layer.
  • Ultra efficiency – one 4 kg packaging of ATLAS UNI-GRUNT ULTRA is sufficient for priming:
  • - 53 m² of floor prior to the application of self-levelling mass, - 280 m² of plaster prior to the application of top coat, installation of ceramic cladding, installation of waterproofing, fixing of thermal insulation, - 360 m² of substrate prepared for painting and wallpapering.
  • 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 parameters
  • 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 Consumption. Primer consumption is: 0,022 – 0,075 kg/m² and in practice consumption depends on substrate absorptivity level.
