Mortar washing is a technique used by masonry contractors and DIYers to revitalize old brick home exteriors or create a distressed appearance for new faux brick or real brick surfaces. It involves pre-soaking the brick with water and cleaning the surface, then applying a mortar mix to the brick in an even coat. Brick masons mix a slurry of sand and cement to create a paste they sponge. They assess the brickwork, check for signs of damage like loose mortar or large cracks, and address structural issues before cleaning.
To apply mortar wash, first inspect the bricks for cracks, holes, and soft spots in the mortar. Repair any damages before cleaning and test a small area of mortar wash. German smear relies on mortar for the brick-brightening effect, while whitewash involves paint. A true whitewash is when white paint is thinned out with water and washed over the brick.
To apply mortar wash, mix dry mortar with water using a 70-30 ratio. Apply wet mortar over a wet brick or stone wall and then wash some of it off with a wet sponge or hose. Apply mortar to grout lines, holding the knife perpendicular and working across the line.
Mortar wash is a hand-applied technique that completely covers all bricks on a surface with a specially formulated mortar mixture. The process involves cleaning the brick, mixing mortar in a wheelbarrow, dampening walls with a garden hose, and applying mortar.

Great article; I am inspired! I can’t find that specific type of mason cement, lots of “quikcrete” options out there. Would Sakrete, Type S Masonry Cement” be equivalent (as that is all that I have available)? And is that Grey that you used or do you have to find a white (because I cannot find white anywhere)? Thank you!
