10 Easy Tips to Concrete Sealing. These tips can be used for all types on concrete, bricks, and masonry. Examples would be driveways, garage floors, brick chimneys, patios, block walls, etc.

1. Make sure you understand the different types of sealers that are available for concrete, bricks, and masonry surfaces. There are water-based and solvent-based sealers. Some will enhance the color while leaving a shine. Others will water repel the surface or internally seal.

2. Clean the concrete to remove dirt and grime with water. Pressure Washing would be the easiest. If you have stains, it is best to use a cleaner that is specific to the stain. Examples: Use a degreaser for oil spills, Use a rust remover for rust removal, etc.

3. After cleaning it is important to let the concrete dry before sealing. How long depends on the sealer being used. Typically 24 hours is adequate. Watch out for rain and sprinklers!

4. Prior to sealing it would be advisable to sweep or blow off the concrete with a leaf blower.

5. Apply the concrete sealer per manufacturer directions. Many can be sprayed on with a pump up sprayer. Some are too thick and will require the use of a roller.

6. Take precautions to not get the sealer on other surfaces or vegetation. You can cause discoloration or damage to your plants.

7. When spraying a vertical surface such as chimneys, it is very important to protect roof shingles and the house siding from over spray.

8. Do not apply to much. Following the manufacturer's suggestions as to the amount of coats needed as well to the proper square footage for the substrate you are applying to. Apply evenly as well.

9. Make sure to let the concrete sealer dry thoroughly before foot traffic. Some sealers take longer to cure and they will need longer to dry before vehicles or heavy furniture can be used.

10. Concrete sealers should be reapplied every so often. When depends on the type of sealer used and the amount of traffic. On a horizontal surface concrete sealers typically last 18-36 months, sometimes longer. Vertical surfaces typically last twice as long as a horizontal surface.

    In your case it would be best to start over and remove the uneven sealer. By applying more sealer may compound the problem.

    What type of sealer did he use? Was it a "shiny" acrylic sealer?

    I had a new, uncolored concrete driveway poured. Two days later the contractor pressured-washed and blew it until somewhat dry, then immediately applied a heavy coat of solvent-based sealer which puddled in the joints. It rained about 5 hours later, and the sealer that was puddled in the joints ran out in streams. Now the driveway looks unevenly stained and a mess. Some of the sealant ran down the drain pipes and out into the back woods behind our house. Will we have to strip and reseal? Thanks.

    It is hard to compare since I do not know which sealer (we have 30+) of ours you are inquiring about. Also the sealer from WV, is is solvent based or water based?

    I have sealed my stamped sidewalk every eyar for the past 7 years. Iused a good sealer that can only be purchased in West Virgina, I live in Pa. I mix it with a small can of walnut stain to give it a dark look. Can I do the same thing iwth yours? And will I still have to do it every year? Thanks Bill marusko
