    It depends on how you plan on using DensShield Tile Backer. For Walls and Ceilings on a wood frame (galvanized roofing nail), use either a 38mm or a 45mm. For Walls and Ceilings on a wood frame (buglehead), use a 32mm or a 41mm. For Walls and Ceilings on a steel frame (buglehead), a 32mm. Lastly for floors (either galvanized or buglehead), use a 32mm on 1/2" thick board.

              Great product
              Great product for a DIY person like me. Great price. Great backer board for a shower. Really durable. Cuts really nice with my table saw. Very precise. I tried with a utility knife but the table saw works great cuz the joints are perfect. I was impressed with this product.

                There was some forklift damage to a few of the sheet edges upon delivery. Otherwise as to be expected.

                Good bang for the buck.
                Purchased at HomeD. Great product for the price point. Used it for a master and guest bathroom shower. I just wish they would have recommended a screw. I ended up using deck screws to secure to the walls.

                  Absolutely excellent product. Used different types of backer board in the past. Cuts like normal drywall. Not as lightweight as some products but worth the extra struggle. Easy to install.

                  Works great, and same thickness as drywall
                  Did my daugters bath surround using this stuff. Easy to cut, mount and waterproof.I added a few coats of Redguard as extra precaution but likely overkill for shower walls. What really is nice is that the material was the same thickness as my drywall making butting the two together perfect. I've used Hardi in the past and it is thinner than my drywall creating issues and more boring drywall/texture work.

                    I used this after removing old backsplash took the drywall off with it. I have never put up any board before. I was able to do it without problems. Follow instructions on how to tape and seal seams with correct product. The new backsplash went up and adhered without any issues.
