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.
How do you fill and seal the gaps between cement and brick or cement and cinder block AND how do you fix the cracks in a cinder block wall?
I think the best thing to use in both cases is LePage Poly Super Strength Cement, a fortified, quick-setting, patching cement because of its great bonding ability and the fact that it sets up in just a few minutes. Make sure the area to be patched is clean of mold, dirt, etc. Dampen the area with water. Mix up the poly cement into a paste and pour it into the gaps, working it with a putty knife to make sure it is compacted into the gap. Build it up a bit with the putty knife or trowel to ensure that water will runoff. Work quickly because it sets up fast. Read the carton for further instructions. This product is better than just sand and cement since concrete will shrink when drying.
