Q:Can i use this to seal an interior brick wall in my store?
by|Dec 11, 2022

Answer This Question

A:  Wall - Thank you for your question. Siloxane 7 is designed for exterior applications for its water repellency. For an interior application, you could use DRYLOK® Natural Look Sealer which has a matte finish, or if a gloss sheen is desired, DRYLOK® WetLook Sealer. Both are available on homedepot.com in gallons and 5-gallon containers. If you would like to discuss your project in more detail, please call our Technical Service Department at 1-800-UGL-LABS

    A:  You can but I'm not sure why you would. It's purpose is to seal out moisture. On exterior brick it helps prevent chipping of the brick from the freeze thaws during the winter. At least the kind I have does not change the look of the brick at all.

      Q:Will this product seal the small cracks on edges of mortar on horizontally installed brick allowing water to seep down thru that crack?
      by|Nov 10, 2022

      Answer This Question

      A:  Phil, DRYLOK® Siloxane is not a patching product so if the cracks are open, they should be repaired. DRYLOK® Siloxane 7 is a water consistency siloxane that penetrates the surface without changing the appearance. It can be used after the small cracks have been repaired. If you would like to discuss your project in more detail, please contact our Technical Service Team at 1-800-UGL-LABS or ugllabs@ugl.com

      by|Nov 10, 2022

        A:  It causes the brick and mortar to repel water rather than letting it seep in. But it doesn't seal visible cracks. It's consistency is thin.

            The sealer was easy to apply using a garden sprayer. Seems like it sealed the concrete is there is no more dust. I had multiple problems with delivery- Leaking and missing bottles.

            Great product poor shipping
            I’ve used this before and it works. Problem is that there isn’t protection in the packaging and it leaked all over the place during shipping. If you are getting this online make sure your select ‘pick up in store’.

              Very Effective and surprisingly economical!
              I bought this product to seal some badly leaking chimney shoulders that were already painted. I applied the product liberally using only a car wash brush mounted on a long roof raking pole. It stopped all the leaks in spite of the paint. The product found all the vulnerable crevices and sealed them perfectly even against driving and persistent wind and rain. Amazing.

              The only reason for the poor rating, is because I wanted to use this on my new concrete driveway. I called the manufacturer about an application question and they informed me the product is not recommended for vehicular traffic. My ordering and return experience with Home Depot was fine.
