To finish strong you need a Superior Primer that can help solidify and protect the surface. Integrally colored Sanded Primecoat Primer helps make finishes brighter and deeper, reduces efflorescence and extends finish coverage rates and provides extra grip for the textured finish. Suitable for priming new stucco and concrete that has a pH of 13 or less.

Job Conditions – Air and substrate temperature for application of Sanded Primecoat must be 40°F (5°C) or higher and must remain 40°F (5°C) or higher for a minimum of 24 hours. Provide temporary protection to protect the wall system from damage until permanent flashings, caps and sealants are installed. Store materials within prescribed temperature limits and out of direct sunlight. Working and drying times are based upon normal room temperature conditions and will vary with temperature and humidity.
Preparation – The substrate must be approved by Master Wall Inc., clean, dry, structurally sound and free of efflorescence, oil, grease, form release agents and curing compounds or anything that would affect bond. Painted surfaces are not acceptable and must be removed.
Concrete – Must have cured a minimum of 28 days prior to the application of Sanded Primecoat. If form release agents or curing compounds exist on the surface, they must be removed with a solution of muriatic acid or similar product (with appropriate precautions). Remove any residual acid by flushing with water. All projections must be removed and any voids filled with F&M, F&M Plus, or MBB.
Masonry – Skim coat with F&M, F&M Plus, or MBB to achieve a smooth level surface. If joints are not struck flush, multiple coats may be required. Contact Master Wall for more information.
Stucco – Must have cured to a minimum pH of 10 or less or aged 7-14 days and be clean, dry and hard with a prior to the application of Sanded Primecoat. If additives were used in the stucco, it is recommended that a test patch be made to evaluate bond strength of the Sanded Primecoat to the stucco.
Master Wall Base Coats or Finishes/Previously Painted Surfaces/Cement Composition Siding— Install and prepare according to published guidelines. Surfaces should be clean, dry, cured and ready to receive coatings.
Mixing – Thoroughly stir Sanded Primecoat into a homogenous consistency. Small amounts of clean, potable water may be added to obtain a workable consistency. Do not over mix. Do not exceed 24 ounces (0.7L) of water per pail. Do not add accelerators or retarders to Sanded Primecoat.
Application – Sanded Primecoat can be applied by brush, roller, or airless spray equipment. When using a roller, a maximum ¾” (19 mm) nap is recommended. Apply Sanded Primecoat in an even, continuous coat of about 3 mils, maintaining a wet edge.
Tools and equipment can be cleaned with soapy water when Sanded Primecoat is wet.
