According to JB:I understand why we put thinset under the CBU. But is it actually supposed to stick to the substrate or uncouple? I say uncouple, This has been on ongoing argument with a fellow tile man.
JB ? John Bridge is that a Mans Name, company, I know of the website, maybe 10 minutes I've been on it.Inner10 said:According to JB: "• Cement Backer Boards Cement backer boards, such as PermaBase, Wonder Board, Durock, Hardi-backer, and others are used to “uncouple” a tile installation from the subfloor below. Before they are fastened, CBUs, as they are called, are bedded in thin set mortar, which is the usual adhesive used in setting floor tiles. The panels are then nailed or screwed to the subfloor following manufacturers’ specific directions. CBUs do NOT improve the stiffness or structural value of the floor."
Neither!, although a good thinset will certainly "stick".TileWizard said:I understand why we put thinset under the CBU. But is it actually supposed to stick to the substrate or uncouple? I say uncouple, This has been on ongoing argument with a fellow tile man.
Pretty sure he's still on the air hawking whatever products that give him $$ to do soMIKE ANTONETTI said:I see so many discrepancies on TV, does he still have a show? I watched Lizard Lick and thought it was funny so one sat or sun I watched 3 back to back and figured out it was dramatized and kinda dumb. I think I'm over all those BS shows, flip em!
