Preserve and protect your concrete investments with Concrete Responder Sealer Water Repellent.
This premium penetrating water repellent utilizes a silane-siloxane formula to provide long-lasting protection for a wide range of concrete surfaces, including driveways, patios, walkways, and structures.
So, how does it work? Concrete Responder's advanced formula penetrates deep into the pores of your concrete. The silane and siloxane molecules react with the silica and other minerals within the concrete 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, Concrete Responder is designed not to alter the appearance of your concrete.
Key benefits of Concrete Responder:
- Advanced Silane-Siloxane Formula: Penetrates deeply and reacts with concrete 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 concrete while reducing biological growth, chemical, and water damage.
- Ideal for a variety of concrete applications: Preserve and maintain your concrete surfaces.
- Easy to apply: Use a spray, roller, or brush.

from 76 reviewsI bought from them a few different times, the product comes quick, high quality, definitely recommend
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.
Great product. My order was filled quickly. We had some mortor joints we repaired and the color samples were ordered were a great match.
Great products and fast shipping, provided exactly what I needed. Highly recommend!
I couldn’t get the Type O mortar locally and Pro Mason Supply got it to me fast
Got their type O for my 1940's house. Works great, amazing product. Their support staff was also very helpful at editing my order. Highly recommend
Great customer service. Emails were responded to in a timely manner, answering all questions in detail. Product was easy to work with and the job finished off beautifully
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!
Took me a year (due to pauses in the project) but I’m finally finished! Stripped thick white paint off of my fireplace and all the scrubbing and scraping left the brick with a grey wash. I used the burgundy stain and it’s like it was never painted!
Will need help with the proper dilution level of your stone gray color
Loved how this turned out. Before and after. I used the charcoal gray and added randomly. I LOVE the way it turned out!!!
Fantastic experience. Ordering is so easy, shipping is fast, and the plaster has been easy to use.
