Preserve and protect your masonry investments with Responder Sealer Water Repellent.

This premium, non-film-forming, natural-look water repellent utilizes a silane-siloxane formula to provide long-lasting protection for a wide range of masonry surfaces, including brick, stone, concrete masonry units, and stucco.

So, how does it work? Masonry Responder's advanced formula penetrates deep into the pores of your masonry. The silane and siloxane molecules react with the silica and other minerals within the masonry to form a breathable, water-repellent matrix. This allows vapor to pass through, preventing moisture buildup, while effectively blocking water absorption, protecting against cracking, spalling, and efflorescence.

With its no-sheen natural finish, Masonry Responder is designed to not alter the appearance of your masonry. It is also ideal for use on many historic structures.

Key benefits of Masonry Responder:

  • Advanced Silane-Siloxane Formula: Penetrates deeply and reacts with masonry to form a breathable, water-repellent barrier.
  • Water-based formula: Easy to apply and cleans up with soap and water.
  • Affordable, long-lasting protection: Premium higher solids-content formula provides long-lasting protection against water damage.
  • Excellent coverage: Covers up to 250 square feet per gallon.
  • No-sheen natural finish: Helps maintain the natural appearance of masonry while reducing biological growth, chemical, and water damage.
  • Ideal for modern masonry and many historic applications: Preserve and maintain masonry.
  • Easy to apply: Use a spray, roller, or brush.

I purchased the Pro Mason Supply masonry stain in hopes of muting the orange tones in the brick around our fireplace. It worked even better than I had hoped. I was so happy that it muted the orange and love the warmer brown hues. It was very easy to apply and there is no odor - and dried quickly!

I bought 5 gallons of PHL 3.5 Lime Mortar to repair the old stone walls of my basement. I am about halfway done the job. I will soon order another 5 gallons because this product is perfect for the job.

Ordered masonry stain to change the color of my stone grout. Love that I don't have to re-grout in order to get the look I'm going for. Keep up the good work!
