Concrete sealant provides a protective coating for masonry surfaces. Seal a stamped concrete sidewalk with a non-breathable sealant to protect the surface of the stamped concrete from absorbing moisture, which can allow water to freeze below the surface and increase the rate of deterioration of the concrete. Apply a new coat of sealant annually to protect the stamped concrete from the weather and reduce the risk of stains from spills.
Things You'll Need
- Stiff broom
- Plastic tarps
- Concrete sealant
- Hand pressure sprayer tank (if spraying)
- Paint roller (if rolling)
- Thick-napped cover (if rolling)
- Broom handle (if rolling)
Clean the stamped concrete with water from a hose and stiff broom. Allow the concrete to dry thoroughly before applying sealant.
Place plastic tarps over grass and/or gardens along the edges of the stamped concrete to protect them from overspray from the sealant.
Mix concrete sealant with a paint stir, making sure to combine the sealant completely. Scrape the bottom and sides of the container to blend in all settled particles.
Pour the concrete sealant into the reservoir of a hand pressure sprayer. If using a paint roller, fill a paint tray with sealant.
Start spraying at one end of the stamped concrete sidewalk and apply the sealant with a sweeping movement of the sprayer wand. Keep the wand moving and apply a thin coating without leaving puddles. If applying the sealant with a paint roller, start from one edge and roll the sealant onto the concrete in a thin, even coat.
Allow the sealant to dry according to the time recommended on the product label. Apply a second coat after the first coat has dried.
Remove the tarps from the vegetation on the edges of the sidewalk as soon as possible to prevent damage to grass and/or plants.
Tips & Warnings
- Rock salt can interact with the sealant and cause degradation of the protective coating. It is preferable to use a shovel or broom to remove snow from stamped concrete.
