Interior Mineral Primer

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 drywall and plaster should be sanded smooth with all dust removed.  One coat of Mineral Primer is required for previously painted surfaces and two coats may be needed for new drywall to create a uniform mineral matte surface.

Primer should be well mixed with a slow speed drill and paddle attachment until homogenous.  The primer may be too thick to stir by hand.  Do not thin primer, apply as supplied. 

Apply primer by brush, roll or airless spray.

• Nylon/polyester brush
• 3/8” to ¾” nap synthetic roller cover (depending on surface texture)
• Airless spray:
  • 3000 psi, minimum
  • Tip: 031” tip minimum
  • Remove pump manifold filter and spray gun filter (use only siphon tube filter)
  • Back-roll from ceiling to floor for best results

Apply primer in a full, even coat to completely cover surface.  For new drywall, two coats may be required for best results.  Apply without drips, runs, or sags in wet primer. 

Drying times are temperature, humidity and thickness dependent.  Cool and damp conditions will slow down drying.

Dry to touch:  2—4 hours at 70°F and 50% R.H. 

Recoat:  4—6 hours

Clean spills, spatters, hands, and tools immediately after use with soap and warm water. After cleaning, flush spray equipment with a compliant cleanup solvent to prevent rusting of the equipment. Tools should be kept in the paint material or in water during work breaks.
