Zinsser ZINGS1L GS1L Gardz Sealer Primer 1 Litre, 1L, Clear

Zinsser Gardz Sealer Primer is a premium clear, water-based acrylic resin sealer designed for penetrating porous surfaces deeply. This innovative product dries quickly, forming a durable, moisture-proof film that effectively prevents issues such as drywall blistering, bubbling, and softening of texture finishes. Furthermore, it substantially improves adhesion on chalky surfaces and seals in any residual wallpaper paste, making it an essential product for various surfaces and conditions.

Recommended Uses

- Damaged Drywall: Gardz Sealer Primer addresses the common problem of bubbles forming when damaged drywall is skim-coated with spackling or joint compound. It deeply penetrates and seals damaged facing paper, restoring the integrity of the surface and preparing it for successful repairs suitable for painting or wallcovering.

- New Drywall/Joint Compound and Spackling: Newly installed gypsum drywall, along with joint compounds and spackling materials, can be excessively porous, leading to uneven and splotchy finishes. Gardz Sealer uniformly seals these materials, creating a moisture-resistant membrane that protects against future peeling, blistering, or loss of structural integrity.

- Plaster: Fresh plaster is not just porous but often possesses a high alkaline pH of 12.0 or more, which can be problematic for subsequent coatings. Gardz can be applied after allowing new plaster to cure for at least 24 hours, ensuring that the surface is clean, dry, and sound. It effectively prepares old, bare plaster surfaces by sealing them after necessary repairs.

- Calcimine: This old, chalky plaster type can be challenging for modern coatings, but Gardz excels here, penetrating calcimine more effectively than traditional oil-based products. Its moisture-resistant properties aid in preventing water-based topcoats from damaging underlying calcimine layers.

- Wallpaper Adhesive Residue: When using water-based coatings on old wallpaper adhesives, there is a risk of reactivating the glue, leading to cracking and peeling. Gardz is specially formulated to seal in these residues, providing a stable base for new water-based applications.

- Texture and Popcorn Finishes: Ideal for textured walls and popcorn ceilings, Gardz seals these finishes before applying water-based primers or paints. It hardens soft or crumbly materials, those which could soften under traditional coatings, thus ensuring a strong barrier.

- Old Wallpaper: For true paper wallcoverings typically installed before the 1960s, a simple water test can confirm the absence of vinyl coatings. Gardz can effectively seal away remnants of wallpapers, allowing for a neat finish once applied directly to the surface.

- Pre-Wallcovering Primer: This product doesn’t just seal; it also sizes and protects drywall facing paper and skim coats, ensuring a well-prepared surface for new wallcoverings. Moreover, it offers protection when old wallcoverings are removed, safeguarding the underlying drywall.

In summary, Zinsser Gardz Sealer Primer is an exceptional choice for various challenging surfaces. Its versatility, rapid drying, and robust sealing capabilities make it an essential product for any renovation or DIY project, ensuring long-lasting results and a flawless finish.
