How to Seal Your Concrete Patio: A Comprehensive DIY Guide

If you have a concrete patio, you know how important it is to protect it from the elements. Over time, exposure to rain, sun, and temperature changes can cause your patio to crack and deteriorate. That's why it's crucial to seal your concrete patio to ensure its longevity and maintain its appearance. In this comprehensive DIY guide, we will walk you through the step-by-step process of sealing your concrete patio using Liquid Rubber, a modern and effective solution.

Using Liquid Rubber: The Superior Solution

When it comes to sealing your concrete patio, Liquid Rubber is the top choice for DIYers. Here's why:

Ease of Use

Liquid Rubber Polyurethane Deck Coating Gives you color options and smooth and textured options for those wanting some extra grip. It is incredibly easy to apply, making it ideal for DIY projects. It comes in a liquid form that can be brushed, rolled, or sprayed onto the surface of your patio. Unlike other solutions that require complex mixing or catalysts, Liquid Rubber provides a seamless and hassle-free application process.

Affordability and Reliability

Liquid Rubber offers excellent value for your money. It provides long-lasting protection against water damage, UV rays, and temperature fluctuations. By sealing your concrete patio with Liquid Rubber, you can extend its lifespan and avoid costly repairs in the future.

VOC-Free and Nontoxic

One of the significant advantages of Liquid Rubber is that it is VOC-free and nontoxic. This means you can apply it without worrying about harmful fumes or health hazards. Liquid Rubber is safe for both you and the environment, making it an eco-friendly choice for your concrete patio.

Identifying the Issue

Before you begin the sealing process, it's essential to identify any existing issues with your concrete patio. Look for cracks, chips, or areas where water pools after rain. These are signs that your patio is vulnerable to water damage and requires sealing. Additionally, check for any stains or discoloration that may need to be treated before sealing.

Preparation for Waterproofing

Proper preparation is key to ensuring a successful sealing process. Here's what you need to do:

Clean the Surface

Start by thoroughly cleaning your concrete patio with Liquid Rubber Deck & Patio Cleaner. Remove any dirt, debris, or loose particles using a broom or a pressure washer. Rinse the patio thoroughly and allow it to dry completely before moving on to the next step.

Repair Cracks and Imperfections

Inspect your patio for any cracks or imperfections. Use a concrete repair product or Liquid Rubber Sealant & Adhesive Caulking to fill in the cracks and level out any uneven areas. Follow the manufacturer's instructions for application and drying time. Once the repairs are complete, make sure the surface is smooth and even.

Test for Porosity

To determine if your concrete patio is porous and requires sealing, perform a simple water test. Sprinkle a few drops of water on the surface. If the water is quickly absorbed and darkens the concrete, it indicates porosity. If the water beads up and doesn't penetrate the surface, sealing may not be necessary.

Etch and Prime the Concrete

Prepare the surface for the application of the sealant using Liquid Rubber Concrete Etch. Etching the surface removes contaminants and minutely roughens the surface, as well as helping by neutralizing the PH of the concrete/masonry, which works to ensure proper and long-lasting adhesion. After this step, use a primer to prime the concrete surface using Multipurpose Primer to fully prepare the surface for the best possible adhesion. 

Steps for Sealing Your Concrete Patio with Liquid Rubber

Now that you understand the benefits of using Liquid Rubber let's dive into the step-by-step process of sealing your concrete patio:

Application of Liquid Rubber

Once the surface is clean, etched, primed and prepared, it's time to apply the Liquid Rubber Polyurethane Deck Coating. Follow these steps to add a protective coating to your patio that is 10x stronger than conventional patio or deck paint:

  • Stir the Liquid Rubber thoroughly to ensure an even consistency.
  • Using a 3/8’’ (10mm) microfiber roller, apply Liquid Rubber Multi-Purpose Primer to the entire surface at a coverage rate of approx. 175 to 200 ft²/ga. 
  • Pay special attention to cracks, joints, and areas prone to water penetration.
  • Next apply one to two thick coats of Liquid Rubber Polyurethane Deck Coating allowing approximately 4-6 hours drying time between coats. Be sure to seal around posts with Liquid Rubber Sealant & Adhesive
  • Allow 24 hours of drying time before heavy traffic or the placing of furniture.

Curing and Maintenance

After applying the final coat of Liquid Rubber, allow it to cure completely. This may take several days, depending on the product and weather conditions. Once cured, your concrete patio will be protected from water damage, UV rays, and other external factors.

To maintain the longevity of your sealed patio, follow these tips:

  • Regularly clean the surface with a mild detergent and water.
  • Avoid using harsh chemicals or abrasive cleaners that can damage the sealant.
  • Periodically inspect the patio for any signs of wear or damage and reapply Liquid Rubber as needed.
