Description
Zinsser Gardz is a unique water-based sealer for porous and potential problem surfaces. Gardz is formulated to deeply penetrate and dry to a hard, moisture resistant film that seals and binds down porous, chalky and crumbling surfaces, paints and textured finishes.
Zinsser Gardz takes the “problem” out of problem surfaces. Deeply penetrating, it dries to a rock-hard, water-resistant finish; this protects surfaces from damage during the next redecorating project.
Gardz is recommended for damaged drywall, new drywall, spackling and joint compound skim coats, plaster, calcimine, uncoated wallpaper, wall covering adhesive residue, textured paint and more.
Application
- Stir well before using.
- Do not thin.
- Using a brush, medium nap roller or sprayer, apply Gardz liberally to the entire surface to ensure good penetration.
- Do not over-apply or coating will sag.
- Gardz appears milky blue-white during application but dries-water clear; properly sealed surfaces should have a uniform sheen when viewed at an angle.
- Reapply to areas that have been missed or not sufficiently coated.
- Apply when temperature is above 10?C and below 32?C.
- Warmer temperatures will accelerate and colder temperatures will prolong the dry time of this product.
- Do not apply if humidity is greater than 85%.
- Close container after each use.
- Coverage Approximately 9 – 11 square metres per litre depending upon porosity of the surface and method of application.
- Textured or skim coated surfaces will be very absorbent and may require a second coat.
- Brush ? For best results use a quality nylon/polyester or other, similar, synthetic blend bristle brush with flagged tips. Do not overload the brush or the product will drip and run on vertical and overhead applications.
- Roller ? Use a roller with a 3 / 8? or less synthetic nap. Apply Gardz to walls from the bottom up to prevent product from running down the wall. If this happens, back-roll or brush out the runs to even out the film.
