How To Reseal A Concrete Patio

A concrete patio is a great way to add outdoor living space to your home. However, concrete is a porous material, so it can absorb water and stains over time. If you want to keep your concrete patio looking its best, it's important to reseal it every few years.

Resealing a concrete patio is a relatively simple process, but it does require some time and effort. Here are the steps you need to follow:

1. Clean the patio

The first step is to clean the patio. This will remove any dirt, debris, or stains that could interfere with the sealant's adhesion. To clean the patio, you can use a pressure washer or a garden hose with a nozzle attachment. If you're using a pressure washer, be sure to use a low-pressure setting so you don't damage the concrete.

2. Repair any cracks or holes

Once the patio is clean, you need to repair any cracks or holes. This will prevent water from seeping into the concrete and causing further damage. To repair cracks, you can use a concrete patching compound. To repair holes, you can use a concrete filler.

3. Apply the sealant

Once the patio is clean and repaired, you can apply the sealant. There are two types of sealants that you can use: water-based sealants and solvent-based sealants. Water-based sealants are easier to apply, but they don't last as long as solvent-based sealants. Solvent-based sealants are more durable, but they can be more difficult to apply.

To apply the sealant, you can use a roller or a brush. Be sure to apply the sealant in a thin, even coat. Once you've applied the sealant, allow it to dry completely.

4. Maintain the sealant

Once the sealant has dried, you need to maintain it to keep it effective. This means cleaning the patio regularly and resealing it every few years. By following these steps, you can keep your concrete patio looking its best for years to come.

Additional tips

Here are a few additional tips for resealing a concrete patio:

Be sure to test the sealant in an inconspicuous area before applying it to the entire patio.
Apply the sealant on a day when the weather is mild and dry.
Allow the sealant to dry completely before using the patio.
Reseal the patio every few years to keep it protected.
