Hi all,

I did not have time to put a second coat of plaster undercoat (Thistle
browning) on the first whilst this was going off and have had to leave
the plaster overnight. Some sections are still quite damp and others
are drying out (there were different backgrounds I plastered over) but
I now need to put on a second coat.

As I have left the first coat to dry a little, should I put a coat of
PVA (4:1?) over the surface before I put the second scratch coat on,
or will it be sufficient to damp the surface of the plaster down with
water?

Many thanks

Swin


Just PVA it immediatly before plastering as it helps reduce suction of
applying the final coat.
