old plaster board

[oasis]

pricein a big job loads of board on stud..but it looks like its been sat there a while and the scrim is black?
any thing i should do before skimin?

 

[richardbrown]

You can get black scrim,in fact I found it very good.
If the boards have been sat for a long time or have got damp then I would seal them first before skimming.

with PVA?

 

[richardbrown]

Yes thats the cheaper option 4-1 apply with roller then go for it, or if your feeling flush then bonding agent but pva will be fine

you could put some cream of tartar in your finish to slow the set down never done it myself but it does work

i know some spreads and they swear by cream of tartar they reckon it's brilliant stuff, they said 2 or 3 heaped teaspoons per gauge , i've never used it
