Stamped Concrete Sealer

Stamped Concrete Sealer

MasonryDefender® Stamped Concrete Sealer is formulated for use on properly cured stamped concrete surfaces. It leaves an attractive, durable, semi-gloss finish that protects stamped concrete surfaces from damage and color loss due to ultra-violet light, moisture and abrasion/wear.

MasonryDefender® Stamped Concrete Sealer is designed for use on both interior and exterior concrete. It is suitable for use on a variety of surfaces where a durable semi-gloss finish is desired including stamped/decorative concrete patios, driveways, and sidewalks. This product is designed to protect stamped or decorative concrete surfaces once they have been properly cleaned with MasonryDefender All-Purpose Masonry & Concrete Cleaner.





For new concrete: After allowing new concrete to cure for 28
days, use muriatic acid (available at most hardware or home
improvement stores) according to directions to etch and
prepare the surface. Rinse thoroughly and allow to dry
completely before using MasonryDefender® Stamped
Concrete Sealer. It is extremely important to rinse the surface
thoroughly with water after using muriatic acid, or after staining
with an acid-based concrete stain, to bring the substrate to a
neutral ph level (7). After rinsing, surface should be allowed to
dry a minimum of three to five days prior to sealing. Applying
sealer over an acidic substrate will most likely result in failure.
For existing concrete: Clean surface with MasonryDefender
All Purpose Masonry & Concrete Cleaner per label instructions.
If oil or grease stains are present, use a quality degreasing
cleaner available at most hardware or home improvement
stores. If desired, a pressure washer can be used to rinse
cleaner off and may result in a cleaner surface than rinsing with
a garden hose alone. Allow surface to dry, waiting a minimum
of 6 hours before proceeding to next step.

Mix thoroughly before use. Apply two uniform coats of material to
new, previously untreated concrete surfaces with a pump-up
garden sprayer with a fan-type nozzle. You can also use an airless
sprayer, pad applicator, or short nap roller. Allow the first coat of
material to dry sufficiently to walk on, but not more than 4 hours,
prior to application of the second coat. Avoid puddling or ponding
of product: brush or roll material until it thoroughly penetrates the
surface. Block all drains and use absorptive coverings to contain
run-off or excess material. Use soap and water to remove
overspray as soon as possible.

Coverage Rate: 100 – 150 square feet per gallon on concrete.
Coverage rates will vary based on the porosity of the substrate.
Waxing: For best long-term results on interior surfaces, when
cured, Stamped Concrete Sealer should be sealed and protected
with a waxing compound. Failure to apply and maintain a wax
coating will result in premature failure of the product. On exterior
surfaces no wax coating is necessary.

Note: Over-application of material may cause darkening of

Dry Time: 1-2 hours, depending on temperature and humidity.
Allow 4-6 hours cure time before exposing to foot traffic. Allow 6
days cure time before exposure to heavy traffic, such as forklifts,
automobiles, etc.

Cleanup: Remove any overspray immediately with soap and
water. Dry film can be removed using a razor scraper. Thoroughly
rinse equipment with clean water.
