How To Fill Cracks On Modern Concrete Countertops

Modern concrete countertops are stylish and unique. But concrete is bound to crack. If you own a concrete countertop, filling concrete cracks is a DIY skill that you should learn. It is nice to be able to instantly fill cracks in your countertop. If you know the basic skills, and have the right tools and supplies for the job, you can readily fill cracks or chips in your concrete as soon as they pop up. This article explains what you need and how to quickly repair cracks.

Tools You Will Need

You probably already own a putty knife or squeegee. Either of these tools can be used to spread and smooth the crack filler.

Caulk Tubes and Large Tubs

Concrete comes in smaller caulk tubes and larger tubes with resealable lids. When filling a narrow but long crack, you should buy crack filler in the form of a caulk tube. These are most useful for countertops since the cracks tend to be very thin. If you are filling a couple of holes or chips in your concrete, it will probably be easier to use a tub. The tubs are usually more cost-effective, and they can be easily resealed to use later. Resealing a caulk tube is harder and the filler is more likely to dry out over time.

Clean Before You Fill The Cracks

It is very important that you thoroughly clean out the crack before applying the filler. The cleaner the concrete is, the better the filler will stick to it. You can use a scrub brush or pressure washer to clean out most cracks. Most importantly, make sure there is not mold or soap scum growing within the cracks.

Filling the Cracks

Now that your cracks are clean, and you have the right tools and supplies for the job, you can get to work. First, you want to try to only get the crack filler inside the crack. This is why the caulk tubes are so convenient. You want to fill in just the crack. That is, you don't want to spread the crack filler on top of the concrete too. The putty knife enables you to scrape the crack filler flat. There could be small build up along the edges of the crack after the filler dries. These can be scraped or sanded away very easily after the filler is completely dry.

As you can see, the prep work and having the right materials is the essential part of this job.
