Any one ever used webber {lac) light weight adhesive coat over a minerall wool system? the rep said a 6mm coat for this system max and then sends out a 10mm expansion bead that must be used with this system,he then said 10mm will be okay, i,m going to have to coat out to the 10mm bead for an acryllic finish and wondered if any of you guys have much knowledge of this gear, i,m sure some of the talented ones have Cheers
