Surface Preparation: Allow plaster or new patches to cure at least 24 hours before applying Gardz. Old bare plaster or surface must be clean, dry, and in sound condition. Repair any cracks or holes with spackling past or joint compound before sealing the surface.
Application: Apply only when air, material, and surface temperatures are between 50-90ºF (10-32ºC) and the relative humidity is below 85%. Thoroughly mix before using. DO NOT THIN. Apply GARDZ liberally to the entire surface using a brush, medium nap roller or sprayer, to ensure good penetration. Do not over apply or the coating will sag. GARDZ appears milky blue-white during the application but dries water clear. Properly sealed surfaces should have a uniform sheen. Reapply to areas that have been missed or lack sufficient coating.
Brush: For best results, use a high quality nylon/polyester or synthetic blend bristle brush with flagged tips.
Roller: Use a 3/8 in. nap or less synthetic roller cover or the Zinsser WallWiz® roller. Apply GARDZ to walls from the bottom up to prevent product from running down the wall. For ceiling applications (popcorn) GARDZ may be applied using a power sprayer or garden sprayer.
Sprayer: GARDZ may be applied using HVLP or airless sprayer systems. Use a 0.011 to 0.013 tip and 800-1200 psi for airless application. Maintain a distance of at least 18-24 inches between the spray tip and the surface. If the surface is too fragile for power spray application, GARDZ may be applied with a garden sprayer. Pour GARDZ into the tank and pressurize according to manufacturer’s directions. Adjust the nozzle settling to dispense product in a fine, consistent fan pattern, keeping the spray tip at least 12 to 18 inches from the surface. Follow manufacturer’s instructions for clean up and storage and protect adjacent areas from overspray.
Dry Time: Dries to the touch in 30 minutes and is ready for finish coating or wallpapering after 3 hours. Allow more time at cooler temperatures.
Clean-Up: Clean up spills and paint drips with soap and warm water. Wash application tools in warm, soapy water immediately after use. If product has dried on an application tool, soak it overnight in a solution of ammoniated household detergent and water. Follow equipment manufacturer’s directions to clean spray equipment. Dispose of unused or unwanted product in accordance with local laws regulating water-based coatings.
