Stop working and allow the caulk or sealant to dry or cure. As soon as you get the sealant to the correct height, I want you to cover the caulk with a 1/8-inch layer of the dry sand. I want you to fill the gap as the sealant instructions say and only do about a foot of the gap. Start filling the gap at the farthest corner where you don’t look so much at the gap.

I beg you to read the instructions on the label as well as any other printed literature that comes with the sealant. It’s very important that you follow the directions to the letter when working with these caulks and sealants. Once they cure, they produce a tenacious bond with the two concrete slabs. Do an online search and you’ll discover these in minutes. Look for a hybrid urethane sealant that incorporates silane and end-capped polymer technology. These are normally not found at home centers. I’d then use the caulk that the pros use on institutional and commercial buildings. What I’d do if I were you is to clean out the gap to a depth of about 3 inches. Asphalt-saturated fiberboard was the staple expansion joint material of choice for years. When installing a new slab against an existing one, many concrete masons put expansion joint material between the two slabs. You need to fill it with something that’s flexible.

If you keep the interior of your home at the same temperature throughout the year, your house slab is quite stable and static with respect to size.

Concrete, like just about any other material, can expand and contract as the temperature goes up and down. In the building world, many of us call that gap an expansion joint. The unsightly gap to the right of the sliding screen door is supposed to be there. But before we do, let’s discuss the gap you’re wanting to fill and why it’s important that you do this job right.

Jeff H., Simi Valley, CAĭEAR JEFF: Thanks Jeff for checking out my videos! I’ve got hundreds there about lots of topics.

I’m trying to determine whether to caulk the crack or fill it with some cement-based patching compound.
