What is the Best Concrete Sealer?

Best Concrete SealersConcrete comes in many different types and substrates that can be found both for both interior and exterior applications. There are Concrete Driveways, Vertical Brick Walls, Brick Paver Patios, Basement Floors, etc. Concrete is very porous and can be prone to degradation from Water, Ultra Violet Radiation, wear and tear, etc. By sealing or waterproofing your concrete surface you will add life and protection to your surface.

So what is the Best Concrete Sealer?

The answer to that is dependent on why you are sealing, what surface  you are trying to seal, and what your final expectations are.

There are many different types of sealers for concrete and masonry surfaces. Concrete sealers come in both water based and solvent based formulas. They come in generic formulas for all surfaces or formulas that are specific to the surface you are applying to. For example, you would want a Brick Paver Sealer for a Paver Patio and a Chimney Sealant for you Chimney but you could use MasonrySaver All Purpose Water Repellent for both.

So why seal your concrete or brick? The main reasons to seal and waterproof your concrete are:

1. Preventing hairline cracks due to water expansion during freeze/that cycles.

2. Prevent water penetration and seepage of water through walls and foundations.

3. Enhance the appearance by adding a gloss or darkening the overall color.

4. Prevent damage from deicing salts during winter months.

5. Provide protection from “Pitting” or “Spalling” or deterioration of the concrete causing chunks of the concrete to separate from the concrete structure.

Once we understand the surface we are treating and what the reasons we are treating the surface for, then we can narrow down what would be the best concrete sealer to use.

    • Concrete Sealer Help says:

      You can use the SuperSeal 30 for the pavers. Wet look and gloss sealers only look good though on decorative surfaces such as pavers, stamped, stained, etc. If the driveway and garage are regular poured concrete, then these type of sealers will not look good. You would need more of a regular water repellent. What surface type are they?
