Review: Good stuff. - Easy to apply and does the job.
Review: ABSOLUTE LIFE SAVER!! - 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!

## Questions & Answers

**Q: I plan on us using the in newly plastered walls/ceiling, what is the coverage per litre?**
A: It depends on how porous the surface is, but the spec is between 5 & 10 sq/m. Just wondering why you intend to use on new plaster though, if its to prep for painting them a wash coat of emulsion should do rather than Gardz, if it's to paper then watered down PVA. Garda will do both these things but it's more expensive to do so.

**Q: Would this work on walls that have been painted over distemper or do I need to scrap all the paint off and start again?**
A: I have used this on walls that were distempered.  I brushed off the loose bits then just painted over it with Gardz.  It bonds the surface into a solid base ready for painting over.  It's brilliant!  But it is very messy to use because it's very thin and drips everywhere.  Then again it cleans up with soap and water.  Highly recommended!

**Q: Can i use this to seal a bathroom cabinet after its painted? Does it dry Matt or silky?**
A: It dries slightly silky, but why do it? I used it to seal in old wallpaper paste as it reacts when painted with emulsion paint. I had no problems.

**Q: I've used this to great effect on some inside (brick) walls of an outbuilding. Is it likely to be any good for brick *cellar* walls? (cold not wet).**
A: Hi, Zinsser Gardz is best used on the following surface - Drywall, Plaster, Calcimine, Wallpaper
