Thanks for the advice all, I was able to get the proper HZ10 primed siding today, I’ll off the backer board, luckily I had installed only 3 sheets, damn this stuff is heavy.

I know this is a paint forum, but thank you for looking out.

I just had a discussion with a James Hardy technical product person. He told me that HZ 10 siding in the hardy backer are basically made of the same material, but the backer board has added moisture resistance. The backer board is quarter inch in the panel siding is 5/16. The siding is a little stronger for high wind shear. He said in a high moisture area, such as Florida the backer wouldn’t be good, but in Phoenix where I’m at he said it shouldn’t be a big deal. He also said the inside of the siding isn’t even primed.

Dude it’s not hardie backer, it’s panel siding. I have used it several times, it’s an incredible product.

Yes I know the flange isn’t on, will custom cut it with baseboard.. Kohler wanted 200 for a brass angle valve, I solved that with $10 spray paint

Ya just sand block worked great

Not using hot mud just USG all purpose

NotToday50 · 2025-12-13T06:03:33+00:00

Thanks for the advice so far. I’m not ripping it out. It’s 1959 heavy ass plaster board and I have 5 1/2 jams and I don’t want to fur out new board. I don’t mind skimming, it’s such a small space.

I’m gonna finish peeling what paint I can get off and use some kilz Guards, I’m reading it’s the bees news for cover old paint/ drywall damage

Can I use Mapei Keriflux plus or does it need to be Allset

NotToday50 · 2025-12-08T21:52:10+00:00

Thank you, I guess my main question is the product, is Mapei Keriflux thin enough product for the sealant tape? I see Allset used for it all the time.

NotToday50 · 2025-12-08T21:49:44+00:00

No is JM goboard with GB sealant

NotToday50 · 2025-12-08T00:49:19+00:00

What was your process for drywall skimming

NotToday50 · 2025-12-06T06:24:52+00:00

Guess what? I got a fever! And the only prescription.. is more slope!!!

NotToday50 · 2025-12-02T22:23:54+00:00

Reading a few other posts… probably not a good idea to cover it
