Zinsser ZINGS500 GS500 Gardz Sealer Primer 500ml

Zinsser Gardz® Sealer Primer is a versatile and efficient clear sealer designed to address a variety of surface issues, particularly in drywall and plaster. This water-based, acrylic resin primer deeply penetrates porous materials, providing a robust moisture-proof film that effectively prevents problems like blistering and bubbling on drywall surfaces.

Key Features

Zinsser Gardz® Sealer Primer offers numerous benefits that make it an essential product for both DIY enthusiasts and professional contractors:

- Fast Drying: The primer dries quickly, allowing for efficient project completion without long waiting times.

- Moisture Resistance: It forms a hard film that prevents moisture damage, ensuring lasting protection for treated surfaces.

Recommended Uses

Gardz® is specifically formulated for a range of applications, making it ideal for various scenarios:

- Damaged Drywall: It effectively seals damaged facing paper, ensuring a sound surface for repairs and preparation for painting or applying wallcoverings. It prevents bubbles when surfaces are skim-coated with spackling or joint compound.

- New Drywall and Joint Compound: New gypsum drywall and joint compounds are often porous, leading to uneven finishes. Gardz® penetrates these materials, creating a moisture-resistant film that combats future damage.

- Plaster Applications: For freshly applied plaster, which is highly porous and alkaline, Gardz® can be applied after allowing the plaster to cure for at least 24 hours. It is essential to ensure the surface is clean and sound before priming.

- Calcimine Sealing: Gardz® is particularly effective for sealing calcimine, an old and highly chalky plaster. It prevents water-based topcoat paints from damaging the underlying layers.

- Wallpaper Adhesive Residue: The primer integrates seamlessly with old wallpaper adhesive, sealing it in to prevent moisture-related issues during the application of new water-based coatings or texture finishes.

- Textured Surfaces: It is well-suited for sealing texture finishes and popcorn ceilings, providing a durable barrier that protects against the softening of texture materials during painting.

- Old Wallpaper: Suitable for sealing true paper wallpapers, Gardz® can be applied after ensuring any loose edges are removed.

Additional Benefits

Gardz® does not just seal; it also binds chalky surfaces and strengthens soft textures, making it ideal for pre-wallcovering and as a bonding primer for old, flaky paint. With its clear finish, it guarantees maximum compatibility with various topcoat options while also ensuring a strong bond to existing glossy or solvent-based paints.

In summary, Zinsser Gardz® Sealer Primer is an essential solution for anyone dealing with problem surfaces, providing both sealing and reinforcement to ensure lasting, beautiful results.
