Mar 12, 2020 · The can of Gardz suggests using it as a sealing coat on top of the joint compound before painting. Given that I've used a mix of hot and premixed mud, and can't be sure I won't be sanding back into the hot mud in spots as I finish leveling the surface, that would seem to be sure to uniform the surface as well as block moisture, if their claims ...

Jan 30, 2020 · Gardz is a great product to use for priming drywall. I'm not sure why it doesn't get more use this way. It could just be tradition - it's not a standard white primer. However if people really want what they say they want - i.e. sealing of porous surfaces - Gardz is the way to go.

Feb 2, 2020 · 2) Gardz sealed best - better than 123, but by the 2nd coat of paint the difference was negligible 3) 123 had a slight advantage in hiding texture variations and light sanding scratches. 4) Adhesion was as good as possible for all …

Sep 3, 2013 · Gardz $25 (varies) Rx-35 $25 Klear $15 I think He opened the Rx-35 and Klear cans for me and all 3 products look the same in the can (which is to say, about like skim milk). All supposedly dry clear like Gardz. The only difference in what they claim on the container is that Rx-35 doesn't mention wallpaper paste residue, while the other 2 do.

Aug 20, 2011 · I realize that - Gardz is a clear watery finish for drywall that soaks in and makes a shiny hard finish, closer to shellac in that sense; 123 is a white primer that can be used on many more surfaces including metal.

Jul 19, 2011 · 2) just gardz the joint compound and paint over that. As mentioned above I am not sure if gardz will cause flashing if I only use it on specific areas. 3) gardz only the joint compound and then go over entire wall with a primer like bullseye 123 to ensure no flashing and a consistent primer that covers the entire wall.

Feb 1, 2015 · chrisn, I have only a 1 gallon can of Gardz specifically for sealing the wallpaper adhesive in this bathroom. I had purchased a 5 gallon pail of the Speedhide 6-2 from a local paint store to support his small business and his superior expertise over the SW guy fresh out of …

May 17, 2020 · You dont HAVE to gardz the skim coat, but I like to, because it penetrates the surface and makes it bullet proof. 123 will work as well, as long as you get the dust off the wall. With my shopvac sander, I dont worry about it, though, but wall dust is much less of a concern with Gardz, as it will straight up penetrate a little into the wall.

Dec 26, 2019 · GARDZ is amazing for so many things, but the one thing I can't get it to do well for me is cover patches, the small patches you have with small nail holes, etc. It seems that even with 2 coats of it, I still get a bit of a dull spot.

Oct 14, 2013 · Gardz is your best bet - seals the wallpaper paste and also the drywall compound. You won't need another primer after that before painting your walls. As for the sandpapery feel, I'm assuming the humidity is activating the paste again in some way.
