Lava 20 Fast Primer is a transparent, rigid, deep penetrating, quick drying and fast curing polyurethane primer.Mainly used as a primer for polyurethane waterproofing coatings and polyurethane joint sealants on absorbent surfaces like: Concrete, Mortar, Plaster, Wood etc.

CONSUMPTION:0.200 kg/m? in one layer
This coverage is based on practical application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature, humidity, application method and finish required can alter consumption.

Application. Surface Preparation
Careful surface preparation is essential for optimum finish and durability. The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the membrane. Maximum moisture content should not exceed 5%.
Substrate compressive strength should be at least 25MPa, cohesive bond strength at least 1.5MPa. New concrete structures need to dry for at least 28 days. Old, loose coatings, dirt, fats, oils, organic substances and dust need to be removed by a grinding machine Possible surface irregularities need to be smoothened. Any loose surface pieces and grinding dust need to be thoroughly removed
WARNING: Do not wash surface with water! WARNING: Do not use a metal-ball blasting machine to grind the surface, because the heavy metal-ball impacts, destroy the cohesion of the concrete surface and lower its stability.
Apply Lava 20 Fast Primer by roller or brush, until the surface is covered. You can use airless spray allowing a considerable saving of manpower. While the primer is still a bit tacky, apply the polyurethane coating or the polyurethane joint sealant.

RECOMMENDATION: If the surface is very brittle, like lightweight concrete or high porous cement screed, apply two layers of Lava 20 Fast Primer
