Always ensure the surface to be treated is clean, dry, and free from any dust or possible contaminates.

• Remove any loose or peeling paint or wallpaper by sanding or scraping the surface. (Always take special care when sanding or scraping old surfaces, ensure to wear a suitable face covering to avoid inhalation.)

• Seal any stains with Zinsser Stain Killing Primer-Sealer

• Cut away loose or torn drywall facing paper with a razor or sand back with 80-grit paper until a sound area is reached. If drywall is gouged, remove loose pieces of gypsum core

• Remove loose wallcovering and residual wallcovering adhesive using DIF Wallpaper Stripper

• Skim coated or spackled areas should be sanded smooth using 100 grit sandpaper


Before applying stir the product thoroughly and test a small area.

• For best results use a quality nylon/polyester/synthetic brush with flagged tips. A roller can be used we recommend a 3/8” or less synthetic roller

• Do not overload the brush

• Apply Gardz to walls from the bottom up to prevent product from running down the wall

• Brush out any runs as they occur

• When applying to ceilings do not press hard or the product will drip out of the roller

• For ceiling applications where a roller would be too messy Gardz may be applied using a power sprayer or garden sprayer

• Maintain a distance of at least 45 to 60cm between the spray tip and the surface for pressure sprayers and 30 – 45 cm for garden sprayers

Note: Some types of wallpaper and translucent wallcoverings may require an additional coat of an opaque primer after use of Zinsser Gardz.

Note: Always follow the manufacturer instructions found on the tin.
