EFAdeck™ Original 451 industrial paint

Application:
Provides concrete floors with a strong, dust free, chemically resistant surface. Light grey color is standard. This product is for professional use only.

Properties:
Hard wearing, with good resistance against water and chemicals. The abrasion resistance is measured according to Taber-abraser (ASTM D 4060-84): 38,7 mg/1000 rpm. Spills of gasoline, engine oil, diesel, waste oil, battery acid, or brake fluid will not harm the paint, if the spills are removed without delay.

Pre-treatment:

UNTREATED FLOOR:
The floor must be clean and dry - max. 10 % RH. If the concrete has been steel trowelled to make the surface impenetrable, thorough grinding is recommended (pls. see below). Due to poor adhesion, concrete floors to which curing or sealing has been applied can not be painted with EFAdeck™ Original 451.

PRIMING:
The concrete is primed using either EFAdeck™ Original 451, thinned by 30% Synthetic Thinner 0700 68063, or EFAdeck™ Original 454 clear. In order to achieve good adhesion the primer layer is preferably applyed by a broom.
NB! By painting on self-compacting concrete / self levelling compound the first layer has to be diluted 50 % with Syntetic Thinner 0700 68063 and the second layer by 30 %. The toplayer must not be diluted.

FINAL TREATMENT:
After min. 4-6 hours or max. 24 hours drying time, apply one coat of EFAdeck™ Original 451, by brush or roller without thinning. If the paint dries more than 24 hours there is a risk that the topcoat does not adhere to the primer layer. It is recommended to paint with a thinned (ca. 10-30%) EFAdeck™ Original 451 or to sand the floor then. Ensure there is adequate ventilation during application and the entire drying process, as with insufficient ventilation gloss inequalities can occur. If required, a third coat may be applied after min. 12-16 hours, but before 48 hours.

GRINDING OF CONCRETE FLOORS:
Prior to painting a concrete floor, it is necessary to check if the concrete will allow the paint to penetrate and adhere. This may be done by placing drops of water on the concrete surface and observe if the drops remain as pearls on the surface, or if the concrete surface absorbs the water. If the water penetrates the concrete surface, the floor will be ready to paint after cleaning and vacuuming. If the water remains as pearls on the surface of the concrete, the concrete must be ground with a suitable floor grinder or shot blasted. The grinding must be through enough to allow the water droplets to penetrate into the concrete. Sweep or vacuum clean the floor.

REPAINTING OF OLD EFADECK FLOOR:
Loose EFAdeck™ Original 0451 has to be removed. Clean thereafter the floor with EFAdeck™ Cleaner 10% solution and rinse carefully with water. Bare spots without EFAdeck™ Original 451 must be primed with EFAdeck™ Original 451 thinned by 30 % Synthetic Thinner 0700 68063. Paint then the floor with 1-2 layers of EFA deck™ Original 451 undiluted - see: New concrete floor.
