Zinsser Rust-Oleum Corporation Available Rust Oleum 02304 Problem Surface Sealer, 1-Quart, Clear, 32 Fl Oz

Excelente sellador de humedad. Me ayudo mucho con humedad que tenía en el baño. Lo súper recomiendo.

used this after removing wallpaper to seal the drywall before painting, and it worked really well. It went on smoothly, dried evenly, and helped create a consistent surface for primer and paint. It also seemed to seal the exposed drywall well, which gave me more confidence that the final paint finish would look even. The coverage was good, and a little went a long way. If you’re tackling a room after wallpaper removal, I’d definitely recommend this as part of the prep process. It made the painting stage much easier and the end result looked great.

Delivered on time right for the purpose could not buy it anywhere else

Excellent product for sealing up damaged drywall. I used it to help repair the wall after removing the tile backsplash in the kitchen. It sealed up the exposed paper and gypsum without causing it to soak in and lift away. Highly recommend for this type of repair.

This is truly a miracle surface sealer. I had badly crumbled drywall, with the paper gone in patches. Was unwilling to re-drywall so I followed instructions, sanded it down and painted it. You'd never know the problem area was there.
