Any thoughts on that one?

Hi Greg,

I will be painting (sealing) gyprock sometime in the next 3 weeks so I was interested to know if that comment was true. However, I went onto the CSR home page and got a PDF file (on the link below) about the material but I didn't see anything about leaving it for 6 weeks. I will send an email to their technical department (within the next fortnight) to clarify the remark.

In the meantime can anyone else give an opinion on which sealer is best?, or have all the painters given their opinion?

Cheers
MH

The literature says "make sure the joint treatment is thoroughly dry before applying a sealer".

Lets face it, the muck has to be thoroughly dry before it can be sanded.

That is why we presently have our 2 oil heaters in our laundry and toilet so when the plasterer returns tomorrow morning it will hopefully be totally dry.

Well thats blown our carbon credits. Yep I know what you mean, where I've laid the muck on a bit heavy its taken at least 2 days to dry.
