Get tips on how to patch a concrete walkway with an epoxy compound. Find out how Roundup will kill crabgrass and keep it from growing up through the concrete.
LESLIE: Doug in Tennessee, you’ve got The Money Pit. How can we help you today?
DOUG : I’ve got a crack in my concrete – my walkway  in front of my home – and there’s crabgrass that’s continually growing through it.
DOUG: I’ve tried everything. I’ve tried different patches to go in it but it keeps going strictly coming right back up through the center of it.
TOM: Well, are you trying to patch the concrete or are you trying to kill the crabgrass?
DOUG: I’m trying to do both.
TOM: OK. Alright. Well, when you patch – first of all, killing the crabgrass is one thing; I like a product like Roundup for that. But in terms of the crack, what you need to do is to stop using more concrete or cement to patch that and use an epoxy patching compound. Epoxy is much more flexible and adheres to the concrete surface and it doesn’t freeze and break and strip away. So epoxy products are much more successful in making a repair that’s going to stick and stay around for a long time to come.
DOUG: OK, well that sounds good to me. I’ve tried several things but I have not tried epoxy.
TOM: I think that’s the solution, Doug. Thanks so much for calling us at 1-888-MONEY-PIT.
