## Description

Zinsser Gardz & reg; Sealer Primer is a clear, water-based, acrylic resin sealer that penetrates deeply into porous surfaces. It dries fast, and forms a hard, moisture-proof film that prevents drywall blistering and bubbling. It binds down chalky surfaces, strengthens soft texture finishes, and seals in residual wallpaper paste. Gardz & reg; Sealer Primer can be applied to high-pH surfaces, and is easily cleaned up with soap and water. Recommended Uses: Damaged Drywall: prevents bubbles that form when damaged drywall is skim coated with spackling or joint compound. It penetrates and seals damaged facing paper, restoring it to a sound surface for repairs, suitable for painting or wallcovering. New Drywall / Joint Compound and Spackling: new gypsum drywall, joint compound and spackling are very porous and can make finish coatings appear splotchy and uneven. It penetrates and uniformly seals, creating a moisture resistant film that protects drywall from blistering, tearing and other damage when redecorating in the future. Plaster: freshly applied plaster is extremely porous but also extremely alkaline with a pH of 12.0 or more in many cases. Allow new plaster to cure at least 24 hours before applying. Before priming old, bare plaster, be sure to determine that the surface is clean, dry and in sound condition, taking care to repair any cracks or holes with spackling paste or joint compound before sealing the surface. Calcimine: is a very old form of plaster that is extremely chalky and water-sensitive. It penetrates calcimine more effectively than oil-base coatings and has a much lower odour. Because it resists moisture, it prevents water-based topcoat paint or texture finishes from softening up calcimine layers underneath. Wallpaper Adhesive Residue: water-based coatings or texture finishes will reactivate old wallpaper adhesive, resulting in cracking and peeling. Formulated to completely seal in residual adhesive and prevent it from ruining water-based topcoats and texture finishes. Texture and Popcorn Finishes: Can be used to seal textured walls and popcorn ceilings before applying water base primer or paint. 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. Old Wallpaper: most of the wallpaper installed before the 1960’s was true paper, with no vinyl coating. To determine if the wallcovering is a true paper wipe a wet sponge across the surface, if the water is readily absorbed it means there is no vinyl coating. This type of wallcovering can be effectively sealed. First, peel away any loose or frayed edges, or whatever remains should be firmly adhered to the wall. Apply as you would to any other wall surface. Pre-Wallcovering Primer: penetrates, seals, sizes and protects drywall facing paper and skim coat, providing a properly sealed surface for new wallcovering. At redecorating time, it protects the surface of the drywall when the old wallcovering is stripped off. Builder & rsquo;s Flat Paint: penetrates chalky, builder & rsquo;s flat paint and binds it to the wall, providing water-resistant protection from paint, wallcovering and texture finishes. Zinsser Gardz & reg; Sealer Primer 1 Litre Colour: Clear. Size 1 Litre.Innovation. Quality. Problem solving. Zinsser was founded on these principles in 1849 and has remained true to its original charter for more than 150 years. William Zinsser The company has been responsible for many industry firsts: B-I-N & reg;, the first shellac-based primer-sealer; Bulls Eye & reg; 1-2-3, the first water-based universal primer; DIF & reg;, the first commercial solution for wallcovering removal and Perma-White & reg;, the first mould and mildew-proof paint. More recently, Zinsser launched Bulls-Eye 123 Plus – a water-based primer delivering performance previously only seen in solvent-based primers – reflecting its ongoing commitment to innovation. Zinsser has earned a reputation as a company that listens to contactors and develops new products – or adds features to existing products – to meet their changing needs.

Review: Works well, quality product from established brand. Recommended. - Good primer sealer. I use this on fresh new plaster to seal and prime ready for paint. Goes a long way as it’s a thin viscosity so acts as a mist coat. Works well, quality product from established brand. See pics of bare plaster sealed/primed and finally painted white. Recommended.
Review: Good stuff - Very pleased with this, well worth the money, better than just using pva. Adherence and coverage was very good. Will use it again for sealing walls after plaster repairs.

### ⭐⭐⭐⭐ Great product but disappointing delivery
*by A***H on 17 September 2025*

I’ve used Zinsser Gardz before and it’s an excellent product – does exactly what it should, seals surfaces really well and gives a great base for painting. I had no issues with the product itself and would definitely recommend it. Unfortunately, this particular order was delayed quite a bit, and by the time it eventually arrived I no longer needed it, so I had to return it. A shame, as the product is fantastic, but the delivery experience on this occasion was disappointing.
