  • Indoor vs. outdoor use: Consider whether your concrete sealing project is for an indoor or outdoor surface, as this may affect the type of product you need. Some liquid rubber sealants are specifically formulated for outdoor use and offer enhanced UV and weather resistance.
  • Finish and color: Liquid rubber sealants are available in various finishes, including matte, semi-gloss, and high-gloss, as well as a range of colors. Choose a product that provides the desired finish and color for your project.
  • Coverage and application method: Different liquid rubber sealants may offer varying coverage rates and application methods. Be sure to choose a product that provides adequate coverage for your project and can be applied using your preferred method (brush, roller, or spray).

Preparing Your Concrete Surface for Sealing

Proper surface preparation is crucial for ensuring a successful concrete sealing project. Follow these steps to prepare your concrete surface for sealing with liquid rubber sealant:

  1. Clean the surface: Remove any dirt, dust, grease, or oil from the surface using a power washer or a concrete cleaner and degreaser. Be sure to rinse thoroughly and allow the surface to dry completely before proceeding.
  2. Repair any cracks or damage: Inspect the concrete surface for any cracks, chips, or other damage, and repair as needed using a suitable concrete repair product. Allow any repairs to cure fully before sealing.
  3. Remove any existing sealers or coatings: If your concrete surface has been previously sealed or coated, you may need to remove the old material to ensure proper adhesion of the liquid rubber sealant. This can be done using a chemical stripper or mechanical methods such as sandblasting or grinding.
  4. Ensure the surface is dry: Before applying the liquid rubber sealant, make sure the concrete surface is completely dry. Moisture trapped beneath the sealant can lead to adhesion issues and reduced performance of the sealant.
