Hi, this is Nicholas Iarocci, the home source guy, owner of Source Development, a home improvement company in Garnerville, New York, and this is how to repair running cracks over drywall or plaster. So, I've simulated a running crack that you'd find in drywall or plaster. You'd seal the drywall crack in a very typical fashion by running compound over the crack. However, if the crack is large, you'd apply either paper tape or this fiberglass mesh here. I'm going to show you both. This is a fiberglass mesh I'm applying. So, homeowners prefer this particular form of tape because it's self-sticking. There's no compound coat before. Once it's installed, fill in with compound. Although homeowners prefer fiberglass mesh, I prefer the paper tape. Reason being is that the paper tape seems to isolate any further cracking. So, I prefer the paper tape. So, I'm going to apply a liberal portion of compound to the crack. Apply the tape over it. Once the tape dries, you apply further coats until you've got a finished product. So, once the tape's been applied and the finished coats are done, you'd apply an elastomeric cover to conceal the crack. And what happens is that this rubber coating expands and contracts, so if there's any further cracking, this will help conceal it. And this is how to repair running cracks over drywall or plaster.
