How To Seal A Concrete Countertop?
There’s a myth about sealing that only professional people can seal the countertops with concrete. Well, that’s not true even a little bit.
This sealing process is relatively easy, and you can do it by yourself at home. Just get ready with your tools, follow this step by step procedure below, and start sealing.
Step 1: Check the Environment
You know, concrete dries too fast. This drying fact mostly depends on humidity, temperature, dew point, and concrete types. While Epoxy Coatings or Acrylic sealers may take 36 - 48 hours to dry, the Silicates may dry up within 1-2 hours!
And, you can’t seal countertops with dried concrete.
So, it’s better to seal your countertop in somewhere with an ample amount of shade. If you are working with kitchen countertops, it will be better to work indoors.
Because wind can dry up the concrete and outdoor dust can hinder the beauty of your sealing. Further, it may cause streaking when wiping off.
And, indoor sealing is by far the best solution To get rid of these problems.
Step 2: Mix the Sealer Dilution
Choosing the concrete sealer and diluting it might be the most critical part of your entire sealing process.
Remember, the generic concrete sealers are formulated for sealing the walls or floors. It’s kinda tricky to work with those sealers while sealing countertops.
Try to get the best concrete countertop sealers to get the best output from your sealer.
If you have the sealer on hand, it’s time to dilute it by maintaining the appropriate water and sealer ratio.
You may follow this ratio - 70% water : 30% sealer to get the best output. This is the appropriate mixing proportion to properly apply the concrete layers on your countertop without facing any clumping issue.
Step 3: Saturate the Countertop with Water
Now, saturate the countertop properly with soapy water. It may take a few minutes, so be patient about that.
After it's been soaked properly, clean it with 100% cotton cloth. You know, cotton is renowned for its softness and causes no harm to the surface.
However, if you wax or seal the countertop before, you have to eliminate those previous wax or seal. Mineral spirits will be an excellent choice to remove previous waxes.
Step 4: Apply Countertop Sealer
In the second step, we have prepared our sealer. Now, it’s time to apply that on the countertop. Try to apply the sealer from the corners to get the best result.
Ensure that you’ve applied the right amount of sealer throughout the whole countertop, and don’t miss a section.
Now, keep it like this for at least 5 minutes. The sealer will soak into the concrete properly by this time.
Step 5: Wiping the Excess Sealer
Get your previously used rag once again and get rid of the extra sealer from the countertop. But don’t dry it up entirely while wiping it up.
Leave a tiny amount of sealer on the surface so that the surface doesn't dry up completely.
Apply the sealer 3-6 times onto the concrete until it stops darkening. If the water is dripped on the surface, it’s the sign of a well-sealed countertop.
That’s all, folks! It’s the end of our guide about how to seal concrete countertops. Now, it’s time to test our work!
Once you've completed the sealing process, let it dry overnight. We will perform a water drop test on the next day to check the sealing quality.
Pour a little amount of water on the countertop and let it sit for around 10-15 minutes. If you don’t face any darkening issue, it means the countertop has been sealed properly.
Conducting this test for once is enough to get the result. But, you may run this water drop test multiple times to get the pitch perfect result. The result will be the same for each test!
Sealing the countertops with concrete is quite a simple task. Simply take some precautions, follow this step by step guides about ‘how to seal concrete countertops’, and you’re done!
Enjoy your newly remodeled countertop!
