Mineral Bonding Primer is a sol silicate mineral based primer designed to prepare exterior new and previously painted masonry surfaces and glossy or tough to paint surfaces for painting with mineral paints. It provides tenacious adhesion and is ideal when multiple types of surfaces and textures are present. It provides added adhesion when renovating or coating sound acrylic and silicone resin-based coatings. Use on new and previously painted brick, stone, stucco and concrete fiber cement siding.
Coverage will vary depending on the type of surface, porosity and texture as well as application methods, equipment and workmanship. When painting brick, we suggest adding 25% to your area to account for painting all edges of bricks.

You will need an extra bucket, painter’s tape, drop cloths a paint roller with a 3/8” or ½” cover, paint brush, stir stick, paint tray and liner, ladder if necessary, dampened cloth to clean up spatters, latex gloves and eye protection.
Previously painted surfaces should be clean and free of loose or peeling paint, dirt, grease, mold and mildew or other household grime and the surface should by dry. New brick, stone, stucco and fiber cement siding should be dry, sound and free of dirt, dust or other contaminants. One coat of primer is required most surfaces. Deeply textured or extremely porous surfaces may require two coats.
Stir Primer until smooth and homogenous. Use a paint brush to cut in around edges and corners then use a paint roller to apply primer to remaining area. It is best to roll into damp cut in paint to avoid creating a “ridge” between dry and wet primer. Apply primer in an even coat with no runs, sags or holidays. Avoid drips, spills and painting adjacent areas. Clean up spills immediately with a damp cloth as it will be difficult to remove once dried. Clean tools with soap and warm water.
Dry to touch: 2—4 hours at 70°F and 50% R.H.
Recoat: 12 hours
