Sealing Concrete and Bricks
Sealing concrete and bricks is very easy. Just clean and apply a sealer. Water Repellent Sealers come in many various types and can be specific to the type of substrate that you will be sealing.
- The use of a pressure washer is suggested when cleaning exterior concrete. Cleaning chemicals are not needed when removing dirt, grime, and vegetation. If you have stains on your concrete then we would suggest using a cleaner that is specific to the type of stain. i.e. Rust remover to clean rust, Oil stain remover to clean oil drips, etc. For interior concrete just use a mop and bucket to clean.
- Removal of old sealers is suggested if your previous sealer has failed. Usually this is noticeable by a yellowing or whitening of the old sealer. Make sure that your substrate can absorb a new sealer. Test be dribbling a few drops of water on the substrate. If it beads up immediately, then a new sealer may not penetrate properly. Some sealers or waxes are considered “film forming” and can be applied on top of other sealers.
- Allow the substrate to dry thoroughly for 1-2 days or what is recommended by the manufacturer.
- Blow or sweep off any dirt or grime.
- Apply sealer by rolling or spraying. A sponge type roller usually works better then a nap roller.
- Let dry for 3-4 fours for foot traffic and 24 hours for vehicular or heavy duty traffic.
*Make sure that you follow all manufacturers instructions.

I have a 105 foot by 30 foot concrete driveway and a 18 foot by 16 foot concrete patio. They both are 4 years old. I just finished power washing them and need to apply a sealer. I live in St. Louis MO so freeze thaw is a concern. I am looking for a product that will protect my concrete, keep it’s original appearance and not make the surface slick when wet. Product suggestion please, and how much product will I need?
Thanks,
Mike
10 Gallons for 2 coats
Just installed 950 square feet of CST paver wanted to know how much SB-6000 I would need
It is not possible to remove an old sealer without chemicals.
I need to remove the sealer/stain from our concrete patio. Can anyone tell us what would be good to do this without chemicals?
After stripping look at the Super Seal VOC versions as it is allowed for NY.
Have a stained concrete area around the pool that whited out Need to strip with the Brick Paver Sealer stripper. roughly 700 square feet Then need a good sealer I live in New York and all I can get is junk any recomendations My buddy suggested that I look up this site
Try pressure washing with a concrete cleaner and degreaser.
MY CEMENT PORCH STEPS WITH BRICK PAVERS WILL NOT COME CLEAN. IS THERE A WAY TO FIX THE APPEARANCE? THE PROBLEM IS THAT THE RAIN WATER FROM THE ROOF COMES DOWN ON THE STEPS DUE TO A FAULT IN THE GUTTER DESIGN AND THE STEPS AND ESPECIALLY THE CEMENT PORTION HAVE NEVER BEEN RESEALED. CAN THE LOOK BE RESTORED IN ANY WAY? THE STAINING LOOKS LIKE DIRT AND OIL.
There is no way to fix the yellow without removing the sealer. If it does not bother you then just reseal over top of it. Most concrete sealers ([url]http://www.opwdecks.com/concrete-sealers.htm[/url]) in general should be re-applied every 2-3 years.
Very good article, thanks. I love it that you don’t need any special cleaning supplies, a good pressure washer will do very nicely.
If the old sealer has yellowed but still appears to hold well, would you suggest re-sealing? Or will it still last for a while?
