Base 381 Tilt Panel Primer is a high performance, solvent based acrylic primer specifically formulated for tilt panels and precast concrete surfaces. Base 381 Tilt Panel Primer has been designed to promote adhesion and provides an alkali resistant barrier improving the life and performance of acrylic based paints and textured finishes.
All surfaces should be clean, sound and free from dry or loose material which should be removed prior to application. Where required, water blasting or acid washing should be carried out prior to application of Base 381 Tilt Panel Primer.
Base 381 Tilt Panel Primer is a solvent based primer and will out perform water based acrylic primers in the presence of form releasing agents. Form releasing agents will prevent the penetration of water-based primers which must be completely removed where Base 381 Tilt Panel Primer can tolerate small amounts of these agents.
Do not apply Base 381 Tilt Panel Primer if rain is expected within 24 hours of application. Keep newly sealed concrete protected from rain for at least 12 hours.
Concrete should be allowed to cure fully (at least 14 days) before application of Base 381 Tilt Panel Primer. Any crumbling, loose or protruding sections of concrete should be removed by grinding and/or acid etching.
Prepare a dilute solution of hydrochloric acid (1 part acid to 20 parts water) and broom over surface. Ensure surface stays wet for approx. 10 minutes and then pressure clean at approx. 3000psi using a liberal amount of water. Allow to dry.
Base 381 Tilt Panel Primer is a solvent based primer and has a strong odour – apply in well ventilated areas only. Base 381 Tilt Panel Primer is highly flammable – take all precautions to ensure no source of ignition is present when applying.
Base 381 Tilt Panel Primer should be applied as 1 even coat over the entire surface. Do not pour over the surface and attempt to flood the area or allow to pool. Use steady long strokes and avoid overworking the sealer or pushing your roller too quickly as this may trap air bubbles in the coating.
Keep the pail sealed when not in use.
Avoid application on hot surfaces.
Base 381 Tilt Panel Primer may be applied using a brush, solvent-resistant roller or airless sprayer. Care should be taken to avoid overspraying onto adjacent surfaces. Any overspary should be cleaned up immediately using a clean solvent soaked rag.
Base 381 Tilt Panel Primer will be touch dry within 1 hour and fully cured within 24 hours.
Base 381 Tilt Panel Primer should be top coated within 1 week of application.
