Keeping your concrete patio, driveway, or stoop properly sealed is an integral part of long-term maintenance. Aside from keeping your concrete investment looking fresh, sealing keeps water from seeping into the concrete and weakening its structural integrity. All concrete, no matter how well it is poured, needs sealant to serve as a viable outdoor structure for any length of time.
While your concrete should have received a good sealing after its installation, you will need to reseal it periodically to keep it looking its best. You could hire a company to do this, but the process is fairly easy to do yourself – plus, you’ll save money while you’re at it! Here’s a quick breakdown on the DIY-resealing process.
The Basics of Resealing Concrete
Before using any resealing product, you should read the directions provided on the container. While we can provide a general overview of the concrete resealing process, a single blog post cannot possibly account for all the individual variations in the products used to do so. No matter which brand or make you choose, adhere to its instructions for the best results!
Now that that’s out of the way, here are the basic steps for resealing concrete:
1. Pressure-wash your concrete structure. This essential part of the process ensures that no dirt or debris gets trapped as you continue. It also will rid your concrete structure of any old and flaky bits of previously applied sealant. If your pressure washer doesn’t quite get the job done, a scrub brush and some elbow grease can take care of any problem areas.
2. Apply the sealant with a sprayer designed for the job. Make sure the concrete is dry before you attempt this step, and make sure you pick the right sealant to avoid coating failure. Concrete structures treated with water-based concrete sealants, for example, should only be resealed with water-based products. Use as little concrete sealer possible to get the job done, as too thick a layer can cause both aesthetic and future structural problems.
3. Wait for the sealant to dry. Depending on the concrete sealant used, its drying time will vary. Read the instructions on the product you choose to use; it should tell you everything you need to know.
Your concrete patio probably was given a protective coating when it was first constructed to save it from the wrath of the sun and rain. However, this coating doesn’t last forever, and a worn-out concrete sealing job is a recipe for cracks and stains.
