Hi, I'm Dave Osborne. With over 50 years experience as a journeyman carpenter, foreman and contractor in heavy construction I enjoyed working with apprentices and sharing the tricks of the trade that others shared with me. Now I get emails from Members all over the world and we include many of my answers in our Free Monthly Newsletters. Some of my answers include drawings and instructions specific to a project, but may also answer your questions. I use correct construction terminology, so you can confidently inform your building supply dealers or contractors exactly what you need.

If you run into a problem or need advice your Membership includes unlimited email questions to me through our Ask Dave quick response button.
I'm confused about whether or not to tape the joints on 1/4" wonderboard, a cement backer board for tile. The manufacturer says not to, but people in the trade say to tape them with fiberglass drywall tape. Any insight on this would be greatly appreciated.
Actually James Hardie recommends the use of a 2" fiberglass tape embedded in thinset mortar to tape and mud the joints.
