Rust-Oleum Problem Surface Sealer | Seals & Protects Against Rust | 02304

SPark: This product is very runny so keep that in mind. It worked well for me while making updates to my bathroom. I would recommend this product to anyone. If you’re reading this and you had drywall that didn’t want to give up the wallpaper that was attached to it and you need to skim coat then get and use this product before you skim coat. Everything will go much smoother once you lock in all the fibers of the drywall.

Lanica Millsap: Works great for me. It makes a nice surface seal in the torn paper areas on sheet rock so that they remain seal down.

Vince: Used this sealer after removing wallpaper and also in conjunction with sheetrock repairs. I had my doubts that it would do what it says it can do. I was wrong. Goes on easy and provided a stable base for a top coat of paint. The paint finish was excellent - the walls look almost perfect. This product works. My only negative remark is on the odor - be sure to setup a fan and open windows to get the odor out.

Jennifer Collins: This stuff is great! I wish that I had found it sooner. I am renovating a mid century home with wallpaper and wood panelling in every room. And every room had different adhesives. I bought this product for the dining room, the final room and the room I wanted to make a show stopper. It smoothed over just about all the imperfections in the walls from stripping, sanding, removing the impossible to remove glue from the panelling. This room is perfect compared to the other rooms where you can still where I attempted to sand, spackle and patch.
It goes on very thin. For one room, you only need about a quart. I would only buy a gallon if you have multiple rooms to do.
Great stuff! Wish I had found it sooner.

Matt A: Good for sealing torn paper on drywall before paint, if you can find this in a spray bottle it would be more practical though

Amazon Customer: My drywall paper peeled when prepping a room for painting. This sealer worked for coating the area prior to priming. I would recommend it. Seller was fast at sending the item!

MS Duffield: 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.

haggis: This is basically a huge container of mod podge as far as I can tell. It is thin and watery but soaks into torn drywall paper very well and seals it up nicely. Smell is not too bad. I used it to fix a wall after taking down wood paneling. If you are planning on skim coating over this stuff though, you need to be aware that you will have horrible bubbling problems on any coat of joint compound after your first coat. Your first coat will be fine, but any mud you put on top of that first coat will look like your house is possessed and your mud was mixed with holy water. Not a few small bubbles... more like the wall is boiling and or carbonated. This seems to be because the Guardz seals the wall up so well that moisture/air no longer penetrates. Your first skim coat of mud once dry is porous like a sponge and full of air. When you apply another coat on top, the moisture soaks into your dry first coat and drives the air out of it. With the wall being sealed by Guardz, the air has nowhere to go but up to the surface, creating bubbles. Then you think maybe you can go over the surface with your knife and knock the bubbles down, but the pressure you apply must force even more air out of...

John: Helps glue all the drywall in place so fixes hold better. Water based so don't leave outside in shed during winter.

Helen Barker: 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.
