Hi, my name is Chris Wade, and I'm a contractor from the city of Los Angeles. Today, I'm going to show you how to repair old grout. If you have old tiled grout in your house, areas you can see some of the discoloration of the grout over time. You can see some of it is starting to flake out a little bit like so. What you want to do is you want to, the first thing you want to do is you want to take a brush and just kind of get the loose debris that's already been sitting there and you want to take any type of a tool that's just got a sharp edge on it, it's skinny, it can get in there, not damage the tile and you just want to flake out whatever you can get out, not applying a lot of pressure because we're not replacing the grout, we're just kind of repairing, repairing what's damaged. It's just old and brittle and you know, you just find the areas throughout your whole countertop that just need to be addressed or walls or floors or this just basically applies to any application that has grout and old grout can be very difficult to get out. It's hard, some of it's been there for 20, 30 years and it's just, it can be a difficult process but now that we've removed all the old grout, the damaged grout, the brittle, whatever the case may be, you just take your grout and you just want to get it in there. Just get it in the areas that you just removed from, just let it get down in there and then you're going to take your sponge that's been dipped in water, squeezed out, just give it a once over, flip it over, give it another one. And that's how you repair old grout. Nothing to it.
