INTER-GRUNT is a general-use priming agent for substrates of any type. It is particularly recommended for smooth substrates of high density and low absorptiveness, e.g. walls, ceilings and other construction elements made of on-site made or prefabricated concrete.
INTER-GRUNT is a general-use priming agent for substrates of any type. It is particularly recommended for smooth substrates of high density and low absorptiveness, e.g. walls, ceilings and other construction elements made of on-site made or prefabricated concrete. Can also be used upon cement, cement-lime, gypsum and gypsum-lime plasters as well as plasterboards. The agent is used for proper preparation of substrates prior to application of gypsum plasters and finishing coats, cement plasters and levelling mortars, thin-coat decorative renders, gypsum adhesives and mortars.
Priming Agent INTER-GRUNT is ready-to-use, manufactured on the basis of dispersion of synthetic resins with addition of quartz sand of high resistance to alkali action. The content of aggregate makes the coated surface appropriately rough, therefore facilitates proper application of subsequent coats and improves their bonding to the substrate. After drying, the coat keeps maroon colour.
The substrate should be stable and cleaned of impurities which might impair the agent bonding, particularly of dust, dirt, form oils, greases, residues of paint coatings and anti-adhesion agents. Poorly bonded substrate elements should be hacked off, loose dusty fragments additionally cleaned with the use of a card. The substrate should be properly aged and its humidity must not exceed 3%.
Keep in tightly sealed original and labelled packages. Keep in dry and cool place, protect against high temperature (above +30°C) and freezing – product freezes and irreversibly loses performance in temperature below 0°C. Protect against direct sunlight. Shelf life is 12 months from the production date given on the package. Incoherence with recommendations listed above may impact the product working parameters.
