DAMAGED DRYWALL
GARDZ prevents bubbles that form when damaged drywall is skim coated with spackling or joint compound. It penetrates and deals damaged facing paper, restoring it to
a sound surface for repairs, making it suitable for painting or wallcovering.
NEW DRYWALL/JOINT COMPOUND AND SPACKLING
GARDZ penetrates and uniformly seals, creating a moisture resistant film that protects drywall from blistering,tearing and other damage when re-decorating in the
future.
PLASTER
Allow new plaster to cure at least 24 hours before applying GARDZ. Old bare plaster must be clean, dry and in sound condition. Repair any cracks or holes with spackling paste
or joint compound before sealing the surface.
CALCIMINE
GARDZ penetrates calcimine more effectively than oil-based coatings and has much lower odor. GARDZ prevents water-based topcoat or paint or texture finishes
from softening up calcimine layers.
WALLPAPER ADHESIVE RESIDUE
Water-based coatings or texture finishes will re-activate old wallpaper adhesive which results in cracking and peeling. GARDZ completely seals in residual adhesive
which can ruin water-based topcoats and texture finishes.
TEXTURE AND POPCORN FINISHES
Use GARDZ to seal textured walls and popcorn ceilings. It penetrates soft or crumbly texture material and hardens it, creating a durable, water-resistant barrier that prevents
primer or paint from softening texture material underneath.
COVERAGE
350-450 sq.ft./gal. (8.6-9.8 m2/l) depending on application method and surface porosity.
SURFACE PREPARATION
Surfaces should be clean, dry, sound and free of dust, dirt, grime, grease, oil, wax, mildew, wallpaper adhesive, or any contamination that may interfere with adhesion.
If unsure of cleanliness, always wash surface with household ammonia and water solution, appropriate cleaning solution or solvent (do not use TSP as a cleaner).
Remove any peeling and/or unsound coatings. Sand any remaining paint film edges smooth. Countersink exposed nail heads, spot prime and fill all nail holes and gouges
with Ready-Patch® spackling compound or equally suitable material.
WARNING!
If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS
BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH-Approved respirator to
control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the National
Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.
MILDEW
Remove interior mold and before painting with a solution of one cup household bleach per gallon of water. Rinse well. Always wear protective clothing and goggles to
prevent eye and skin contact with bleach. Do not add ammonia or other cleaning products to the bleach solution. If you are concerned about mold and mildew behind walls,
underneath flooring, in commercial buildings and schools, follow appropriate guidelines for mold removal.
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 â“ For best results, use a high quality nylon/polyester or synthetic blend bristle brush with flagged tips.
Roller â“ Use a 3/8â 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.
Sprayerâ“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 manufacturerâ™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 manufacturerâ™s instructions for clean up and storage and protect adjacent areas from overspray.
LIMITATIONS
GARDZ is not recommended for floors or decks or surfaces subject to immersion or prolonged contact with water.
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.
TOPCOATING/WALLPAERING
When dry, GARDZ may be topcoated with any standard architectural water-based or oil-based primer or topcoat. GARDZ is compatible with all types of joint compounds
and spackling pastes and any texture or popcorn finish may be applied over it. Some types of wallpaper and translucent wallcoverings may require an additional coat of
an opaque primer such as ShieldZ®Universal.
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 manufacturerâ™s directions to clean spray equipment. Dispose of unused or
unwanted product in accordance with local laws regulating water-based coatings.
