DIY: Driveway Repair

Posted: Updated:

When you go to the store to look at caulking and molding, it might seem easy. You see things like concrete and mortar on them, and you think that's a great item. Or you see a flexible one and it shows concrete right on it. Always read the labels -- especially the very small writing on the back. For instance, it might say it's not for horizontal outdoor surfaces where moisture can collect. Very clearly, these are made for vertical surfaces on concrete walls. They can't be used on the flat surfaces outside. They will lift up, they will come out. You need to read the labels.

Don't just trust the guy that's handing you the tube -- read the label, make sure you know what you are buying. Some will say that they are for those surfaces. It might say it's good on driveways and sidewalks, so we'll assume that's probably good for these horizontal surfaces outside. This is a good decent caulking, but we usually have some that are better. What we like you to look for is the ones that are polyurethane base. They usually have a limestone color on them. That tells them that they will match the color of your driveway. There's from PL called S-20, which is a consumer label. A lot of the contractors will buy one called S-L 1. Basically, these products are the same. They are polyurethane self-leveling caulking that will go in and level, nice and easy. Now fall isn't coming quite yet, so why are we out in the heat and the sunlight? Because we want the heat and the sunlight to level the caulking into these cracks.

Now I did my whole driveway last year, but I have one particular spot where the caulking is coming loose. Either I didn't do it right or there was a little movement in that spot. So we are gonad look at improving that spot. We are going to use SL-1 -- this is the self-leveling polyurethane caulking. Goes in, levels nicely, bonds stretches and moves. You always use a utility knife, cut the tube always use a quarter-inch hole that's right about to feed it out. And then make sure you take a nail and puncture the tube to make the product come out. This spot didn't work out really well, so I will pull that out of there and then sweep all the dirt and debris away, so the product can bond easily to the concrete. We'll then put that caulking in the hole. It will be a little bumpy, but I'm not really worried about that because the tube tells me it will level itself out. This is something you can do yourself, get the right help, the right product and this is something you can do yourself.
