MasonryDefender 2.5 Gallon Penetrating Concrete Sealer for Driveways, Patios, Sidewalks - Clear Water-Based Silane Siloxane Sealer Water Repellent

Used to reseal our breezeway carport concrete surface. Used an all purpose cleaner with my pressure washer for prep, and applied sealant with low pressure 2 gallon hand pump. Nothing particularly difficult with the process. Several things I would note with my experience. I purchased the 2.5 gallon container as a better value over 2 single gallons which I estimated was all I would need. In fact, I wound up using every drop of the 2.5 gallons. Used a stiff brush to disperse pooling, but saw a lot of shadow areas appear while at an early stage of drying. Fortunately, when the surface fully dried these shadow areas were gone and I had a consistently clean matt finished lsurface overall, with one exception. A very small prior oil stain in one area, which had not jumped out when prepping or spraying appeared after the surface had fully dried. But that's a quibble. Obviously, this is one of those products that requires the test of time to tell how good it is as a protectant sealant. But for now, I'm happy with the price, the ease of application, and the final appearance.

Applied to concrete pool deck as a preventative measure for upcoming winter to avoid dirt and such penetrating into concrete requiring powerwashing. Current results - water beads up on treated surfaces (I ordered more). I believe this will have the effect I want next spring. Am buying more to finish the area, I underestimated.
