Gardz High Performance Sealer Water-Base 2.5 Litre

Zinsser Gardz worked really well on my walls, which were in very poor condition. It sealed the surface effectively and covered up the worst of the damage, giving me a much better base before painting. It was easy to apply and made a noticeable difference to the final finish. A very useful product for anyone dealing with flaky, porous or damaged walls.

Great stuff! Needed to use a sealer after removing wallpaper and wanted to paint walls. Really easy to use, covered really well. No smell. Quite watery, so I needed to be careful with application. I also used on eggshell paint, as I wanted to repaint, so a great versatile product. The can covered a large area, so great value for money. Paint adhered nicely over without any peeling issues.

Easy to use

I used this product to seal our kitchen ceiling after removing wallpaper. It is very drippy and thin so if too much on the roller can be messy. On the plus side, it is very sheer and covers well. The finished ceiling looked flawlessly smooth and shiny. I highly recommend Guardz to prime and seal plasterboard ceilings and walls, especially in rooms where there is moisture and grease. I’ll definitely be using it to seal the tongue and groove walls in our guest bathrooms.

Look absolutely no further if you are doing a plasterboard and tape joint job. For dry lining this product is awesome. In fact after using similar products for the last 20+ Years I would say this is the best. It goes on with a brush or roller, sinks in and dries out quickly with a superb hard finish, useful on those external corners! Overall I give this 5 stars. I'll be buying it again. Also, give Wood Finishes Direct a look. They sell some good products and have very good prices.

We’ve always had trouble with the wall going up our stairs. Every time we paint or the weather turns cold, little air bubbles appear. We had dado rails and decided to pull them off BUT it took about 4/5 layers of paint with it so we then had no choice but to scrape and peel every single bit of paint off! We saw this as a blessing in disguise though as we’ve always wanted to go back to bare plaster to sort out the problem. We sanded and cleaned every area, after one coat, it was still doing it!! But this time the paint was scratching off by our finger nails too. So we had to re sand what we’d already done!! Nightmare! After researching, we came across ZINSSER GARDZ, we figured maybe there’s old wall paper paste on the walls as it’s an old house. Zinsser Gardz looks like watery milk but smells of rabbit wee! So I recommend opening windows and wearing a face mask. Also, don’t use a brush! It flys everywhere! Use a small foam roller. It dries like a glue and your wall will be shiny. After one coat of our desired paint we had no paint scratching off and no bubbling! After a few coats, it was perfect! We’ve finally got our walls back! It’s taken about a month of back and forthing and lots of tears but we got there in the end! Yay!

Excellent product

Does the job. Using 2.5l tub I was able to coat one small bedroom (including ceiling) with a single coat.
