We took down the Wood pan line in our old home. Built in 1880. All the room is red brick. Except for this one spot that it looks like they ran out. Using pro Mason stains, I was able to make coordinate better with the rest of the room. Very happy with the results! It would have been impossible to achieve without being able to dilute and combine the stains to make multiple colors to match the variants in the original bricks.

This was awesome. It mixed very well, and even though its still curing, it is very hard now. It was also fun to mix up a mortar by hand the same way they used to do back in the day.

I had my steps repointed but they were way to light and slot of cement left on the brick. These stains worked amazing. Darkened the mortar and made the bricks look new!! Love this product! I used dark buff for the mortar and mixed burgundy and dark red for my brick.

I purchased a type-o mortar concentrate and am very satisfied with the speed of receipt and overall quality of the final product. I particularly appreciated the clear instructions that came with the product that took any guess work out of the picture. I am a homeowner and not a professional mason but this company has allowed me to make reasonable repairs to my chimney brick work with confidence.

My tile/mason guy convinced me to not add any color to my mortar and it drove me insane that I let him talk me out of my vision. I just put the Cream stain on my grout for my bricked floor in my mudroom and I can't begin to tell you how happy I was with the result. We ended up using it strait and didn't water it down. There were some areas that absorbed super quickly and needed a second coat. I can't wait to seal it in to protect it.
