The perfect mortar for 126 year old bricks (granite boulder and brick foundation built in 1900). Very happy with the mortar and clear instructions. Thank you ProMason!

Worked perfectly. Stain changed color of existing brick to the tone I was expecting giving it new life and blends with other new finishes.

I haven't had a chance to mix and use the mortar yet. However, the customer service is great. They immediately sent a replacement package of colorant since the original had leaked.

Easier to apply than I anticipated. My first time staining brick and I was nervous on how it might turn out because I was going from dark brown tone bricks to gray tone (before and after photo submitted)Blended my own color combo and It looks amazing.

The stain covers well and a quart did a good amount of surface area. The perfect shade was achieved by mixing 2 colors. It looks great and is a nice brick border update!

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.
