I had severely damaged walls after removing 50 year old wallpaper. This product was recommended in a YouTube video I watched. I didn’t take any chances and used 2 coats, probably overkill, but the walls were more brown paper than painted surface. The product dried to a slight sheen and was a bit tacky. I waited 24 hours (didn’t really need to) before I started the skim coating. There was no bubbling or adverse affects. My project turned out beautifully. I was very satisfied with the results.

I never tried to skim coat over dry wall that’s been torn down to the brown paper, but I heeded the warnings of everything I saw only. After using this product, I had zero issues with doing the skim coat. And it dried in roughly 15 minutes, not the 60 minutes stated on the label. I’m very happy with this product.

We used RX35 to prime & paint over wallpaper that had been up 45yrs! One coat of RX35, then 1 coat of light beige paint with primer covered completely without lifting the wallpaper. We saved a lot of time, money & headaches by not ripping down the wallpaper or having to patch up old dry walls. What a lifesaver! We’ll definitely use RX35 again!

I am an experienced DIY renovator and have completed five home remodels and hundreds of individual projects such as flooring, wall tile, cabinets and woodworking, paint, etc. The Rx-35 was recommended by several stores (including another nationally-known paint chain) as a remedy for covering wallpaper and wallpaper backing in preparation for painting. The circumstance was wallpaper that had been applied over drywall without priming or sizing, making it impossible to completely remove without extensive drywall damage. The Rx-35 performed poorly in this instance causing repeated bubbling. It is also clear which doesn't allow wallpaper patterns to be adequately hidden. However, I switched to a shellac-based product (Zinsser BIN) and it performed flawlessly. It covered/sealed with no bubbling and the white color provided a perfect base for painting. Forgo the ease of cleaning up water-based products such as Rx-25, I would recommend an oil/shellac based product, specifically Zinsser, over water-based solutions in these circumstances as they are much more reliable in their final results.

This is good stuff. We ripped out original wallpaper and had torn drywall. This bubbled as we put it in then dried completely flat. Next up is skim coat.
