Hi All,
I'm aware when applying multi finish it's best to the leave the PVA mix 24 hours before applying a second coat before starting to skim, but I was wondering when you have a damaged wall with plaster which has crumbled away do you still need to leave the wall for 24 hours after applying the PVA mix or can you roll on your PVA mix and leave it a half hour and then start laying in your thistle bonding coat onto the PVA mix with the bonding sticking better than multi finish or is best practice always wait 24 hours after applying the PVA regardless of bonding or finishing?
Cheers,
