Before applying the HARD PRIMER SEAL CONSTRUCTION, the surface must be clean, dry and free from oils, grease, dust and any other contaminants. It must be applied with a spalter or brush on the edges where the sealant will be applied. Apply the sealant after it is dry on touch (approximately 8 – 10 minutes), being the maximum time for application of the sealant 2 hours. A thin layer must be applied at once. Overlapping layers may cause surface irregularities, compromising the adhesion to the substrate.

NOTE: Hard Primer Seal Construction does not adhere to expanded polyethylene tarucel.
