Description
Zinsser Gardz(r) Sealer Primer 1 litre Colour: Clear.Size 500ml.Zinsser Gardz(r) Sealer Primer is a clear, water-based, acrylic resin sealer that penetrates deeply into porous surfaces. It dries fast, and forms a hard, moisture-proof film that prevents drywall blistering and bubbling. It binds down chalky surfaces, strengthens soft texture finishes, and seals in residual wallpaper paste. Gardz(r) Sealer Primer can be applied to high-pH surfaces, and is easily cleaned up with soap and water. Recommended Uses: Damaged Drywall: prevents bubbles that form when damaged drywall is skim coated with spackling or joint compound. It penetrates and seals damaged facing paper, restoring it to a sound surface for repairs, suitable for painting or wallcovering. New Drywall / Joint Compound and Spackling: new gypsum drywall, joint compound and spackling are very porous and can make finish coatings appear splotchy and uneven. It penetrates and uniformly seals, creating a moisture resistant film that protects drywall from blistering, tearing and other damage when redecorating in the future. Plaster: freshly applied plaster is extremely porous but also extremely alkaline with a pH of 12.0 or more in many cases. Allow new plaster to cure at least 24 hours before applying. Before priming old, bare plaster, be sure to determine that the surface is clean, dry and in sound condition, taking care to repair any cracks or holes with spackling paste or joint compound before sealing the surface. Calcimine: is a very old form of plaster that is extremely chalky and water-sensitive. It penetrates calcimine more effectively than oil-base coatings and has a much lower odour. Because it resists moisture, it prevents water-based topcoat paint or texture finishes from softening up calcimine layers underneath. Wallpaper Adhesive Residue: water-based coatings or texture finishes will reactivate old wallpaper adhesive, resulting in cracking and peeling. Formulated.
