hi there did a re skim the other day and soon as i put the plaster on the wall it went off and started cracking? :oops:

apply pva mixed with water just before skimming a wall it will provide a key for the plaster, give you more working time and create an even suction background.

In addition to PVA, you can also wet the wall a bit prior to plastering. The cracking is the quick loss of moisture out of the plaster. Lee

i am a plasterer by trade, and the best results are by first apply a sealer coat of 1:4 pva to water, allow to dry completely then apply a tack coat of 1:2 pva to water..allow to partially dry then skim.
