How to Seal Concrete

As you should already know, adding a sealer to your concrete is essential. The sealer is vital for protecting the concrete’s appearance and integrity. After you’ve given the concrete enough time to dry, you will want to add an appropriate sealer to it.

The good news is that sealing concrete isn’t too difficult. You just need to make sure that you have the right supplies and properly prepare the concrete. Within this guide, you will learn exactly how to seal your concrete. Please seek professional advice before sealing concrete.

 

Tools And Materials Needed

Before getting started, you’ll want to make sure that you have the appropriate supplies and materials. The requirements will depend on your current situation.

If you’re working with new concrete, you will need fewer supplies. If you’re trying to reseal concrete, you’ll probably need more items.

  • Paint sprayer or roller
  • Putty knife
  • A vacuum cleaner
  • Asphalt brush
  • Chemical stripper
  • Concrete repair
  • Degreaser
  • Concrete sealer

 

When To Apply Sealer

If you’re working with new concrete, you’ll want to let it cure before trying to seal it. Wait at least thirty days before applying the sealer. Also, make sure that you keep an eye on the weather.

Sealer should be applied in dry conditions. Otherwise, it will not adhere to the concrete. The temperature should remain above 50 degrees Fahrenheit for at least three days.

Step 1: Clean The Concrete

Once you’ve gotten everything ready and Mother Nature is working in your favour, it is time to get started. Go ahead and clean the concrete thoroughly.

Use a broom to sweep away the dirt and debris. You’ll also need to remove grease, paint, and oil. You can do so using a degreaser. You may also need to use a knife to scrap away dried paint.

Either way, make sure the concrete is completely free of dirt and debris, before moving forward. Be sure to get rid of stains at this point as well. Anything that isn’t removed will show up in the final product.

Step 2: Mop It

Now, mop the floor with cleaner and water. You should use the shop vacuum to clean up remaining debris and water. Be sure to give the floor twenty-four hours to dry.

Step 3: Fix Cracks

If you’re going to be resealing an old floor, you should make sure it is free of flaws, such as cracks. Use a concrete repair sealant to fix any problematic areas. Use the putty knife to spread the sealant into the cracks and crevices.

Step 4: Remove The Old Sealer
You may have already sealed the concrete. If so, you’ll want to use a chemical stripper to remove it. You can also use a sandblaster, but this is best left for professionals.

Step 5: Apply The Sealer
Finally, you’ll want to apply the sealer to the concrete. Do not put it on thick. Instead, you should apply the sealer in two thin layers. Wait at least two hours between the first coat and the second.

Remember to stay off the sealer until it has completely dried. Depending on the sealant in question, it may take up to three days to dry thoroughly.
