Interior/Exterior Brick Sealer

Interior/Exterior Brick Sealer

MasonryDefender® Interior/Exterior Brick Sealer is designed to seal interior or exterior brick & masonry walls, giving them a slight satin sheen. It is formulated with a durable acrylic resin that reduces water penetration on exterior walls, and minimizes brick dust on interior walls; making brick walls easier to clean and giving them an attractive satin sheen.


MasonryDefender® Interior/Exterior Brick Sealer can be used on most types of above-grade, vertical, interior or exterior masonry surfaces including: brick, stone, stucco, adobe, and moderately dense substrates. It provides a slight satin sheen. If cleaning is necessary on exterior surfaces, use MasonryDefender All Purpose Masonry & Concrete Cleaner.






If necessary, clean exterior surfaces with MasonryDefender
All-Purpose Masonry & Concrete Cleaner per label
instructions. Allow adequate time for the surface to
thoroughly dry before sealing the surface.

Mix thoroughly before use. Apply two uniform coats of
material to masonry surfaces with an airless or lowpressure sprayer. You can also use a brush or roller. Start
at the bottom and apply in a saturating spray. Apply
sufficient material to create a six to eight-inch rundown
below the contact point. Always back-roll to assure proper
penetration and to achieve a uniform application. Allow the
first coat to dry completely, approximately two hours, before
applying the second coat. Reapply second coat in the same
manner as in the first coat. In the case of extremely porous
substrates, additional applications may be necessary. Use
soap and water to remove overspray as soon as possible.
Coverage Rate: Approximately 80-150 sq. ft. per gallon.
Coverage rates will vary depending on surface porosity. Do
not thin product.
