Answers to Your Questions About Concrete Sealer

concrete contractors in san franciscoThere are a number of concrete finishes that you can apply to your new driveway, patio, or floors. The most practical thing you can do to finish off your concrete project is to seal it, which helps to protect concrete from cracking, staining, and chipping. The following are some answers to common questions about sealing concrete. If you’re not confident in your ability to seal concrete yourself, enlist the help of one of the better concrete contractors in San Francisco.

What Should I Do to Prepare My Concrete for Sealing?

Before you start staining, you have to be sure that your concrete has been fully cleaned. If there is dirt or oil on your concrete’s surface, the sealer will not properly adhere to it. Use a stiff-bristled brush and a specialized concrete-cleaning solution to remove grime. Any leftover stains will be sealed under the sealer and will be unsightly.

When and How Should I Apply Concrete Sealer?

Apply concrete sealer on warm, sunny days, and preferably when humidity levels are low. If you try to apply your sealer on overcast or wet days, it will not properly cure. Ideally, you want to work on this project during the summer months when the sun is out. Do not attempt to seal your concrete when temperatures dip below 60 degrees. Also, test a small area with the sealer before you apply it over the entire surface. That way, you’ll know you have the right product for your concrete construction job.

Should I Wear Protection?

When working with any concrete sealer, err on the side of caution and wear protective gear. Concrete sealers usually contain harsh, corrosive chemicals that can cause you harm if they make direct contact with your skin or eyes, or if fumes are breathed in. Be sure to wear goggles, gloves, and appropriate clothing.

Am I Okay Only Applying One Coat?

To ensure even coating of sealer over your concrete construction project, plan to apply several thin coats. Additionally, concrete sealers degrade over time, so you will need to reapply them periodically. To keep your concrete looking its best, reapply your sealer every two to three years.
