Apply Stain with Spraying and Back-Brushing

What happens here

Apply the solid color masonry stain to the wall using the airless sprayer. Immediately after spraying a section, follow up with back-brushing. This technique involves using a large, stiff brush to work the freshly sprayed stain into the porous surface of the brick or stone. Back-brushing is crucial for ensuring that the stain deeply penetrates all the tiny holes and textures, especially on un-coated or very porous masonry, leading to a more durable and natural-looking finish without a thick film. The goal is to achieve a stained, not painted, appearance.
