- Create a loose slurry mix of roughly 80% Lime, 20% Portland cement, and water.
- Dab a mason’s brush with the slurry mix and wipe it on the brick thickly.
- Dip the mason’s brush in clean water and dab off some of the slurry. Over time, weather will continue to wear down the finish.
Mark likes to use a masonry-based whitewash material for exterior brick because it’s more durable against the elements. The lime and Portland cement he used can be found at masonry yards and some specialty home centers.
