10 Easy Tips to Concrete Sealing
These tips can be used for all types of 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 overspray.
8. Do not apply too much. Following the manufacturer's suggestions as to the number 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.
