Zinsser 2301 Gardz Clear Problem Surface Sealer, Gallon

This product miraculously sealed heavily damaged wallboard when handyman made gouges that went into wallboard paper.

I totally wrecked my bathroom's drywall when I removed the wall tile from 3 walls. Torn, ripped, destroyed drywall paper everywhere! So I googled how to fix it and this product was recommended by several of my fav DIY YouTubers. I pulled off and/or cut all the big pieces and roughly sanded the rest then painted it with Gardz. It's goes on clear and is SUPER watery--NOT LIKE PAINT AT ALL--not that I cared as long as it worked. I applied it to all the destroyed drywall and to the rest of the upper walls where the 1970s wallpaper was removed but left gummy adhesive behind, then let it dry for the full THREE hours. I applied Kilz Problem Surface primer on everything and can't believe how good the walls look! Now that I can see the problem areas (there's only 2 small areas about the size of a playing card), I'll hit them with a bit of mud, sand, and prime again, then I'll be ready for final paint. I'm SO GLAD I trusted my DIY guys and gave Gardz a try. It really saved me a ton of time, effort, and money because I didn't have to replace all the drywall. Super happy with my results!

It does a good job but it has some chunks that don't mix with material

Gardz is one of my favorite new product finds. I am using it to prep walls that were almost destroyed by wallpaper removal. you paint it on the bare patches, then skim with drywall mud for a perfect surface. Without gardz, repair is hit and miss. I used to use Kilz oil based primer. It was smelly and did not always stiffen the torm paper surface. Gards is water based, has a pleasant smell, and works 100% of the time for me. It also seals in the wallpaper glue, so I now spend less time trying to remove it. Another use for Gardz is sealing the edges of MDF before painting. I use gardz to seal and stiffen the porous MDF edges, lightly sand the sealed areas then paint. I get a perfect finish every time! Gardz is also perfect for spot repairs on painted walls. Put it over a drywall repair to seal it, then apply finish paint. No flashing like with regular primers! Rarely need to repaint a complete wall now. I don't understand why Zinsser can't get the big box stores and paint stores everywhere to carry this product. I have ordered now a total of 5 gallons via Amazon. Shipping is expensive and twice UPS rough handling caused product to leak and required it to be reshipped. This great product should be on the shelf in every town!

I had trouble getting the white foam ceiling tiles to stick to the old popcorn ceiling so I covered it with this product and now they are stuck on nice and snug!

Excellent one coat drywall sealer after taking down wall paper and preparing for skim coatings. Easy to apply

The item is great the shipping sucked from this merchant. I no longer want it
