plastering second coat board finish onto dried out first coat.

by andy

How do you do the second coat onto plaster board, using board finish,if the first coat has been allowed to dry out overnight or longer?

The 2nd coat has to go on as the 1st coat is firming up, not after it has set. If it has set then you have to start from the beginning again - with a 1st Coat. The previous 1st Coat will need to have PVA applied to it - to make sure it sticks and to control the suction.
