hello to everyone , ain't posted for a long time , hope everyone is keeping busy . quick question for everyone , a builder im working for wants me to go over existing s and c spa finish with parex then re dash it . :RpS_unsure: just wondering if this is ok to do , i was thinking of putting a scratch coat of parmarex on first then finishing off with the maite for the dash coat . the existing render is rock solid by the way, and not painted ( and before anyone asks i don't know why the customer wants it redone lol :RpS_mellow: ) or should i just use the maite as a scratch coat and then again for the dash coat , any thoughts fellas :RpS_unsure:
