General—Air and substrate temperature for application of Superior Stone must be 50°F (10°C) or higher and must remain 50°F (10°C) or higher for a minimum of 24 hours. 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 and surfaces should cure for a minimum of 28 days. Stucco should be cured until clean, dry and hard—typically 14 days.
Interior drywall should be finished and made ready for paint. Prime surfaces with Sanded Primecoat primer prior to finishing with Superior Stone.
Base Coats – Must be flat, dry hard, and free of efflorescence. Master Wall base coats must cure a minimum of 12 hours before application of Superior Finish. Substrates of brick, masonry or concrete should be leveled smooth using either Master Wall® base coats or stucco.
Mixing—Thoroughly stir the Superior Stone Finish using a heavy duty 1/2″ (12.7 mm) drill at 400-500 rpm and a paddle similar to a Wind-lock B-MTW mixer. Small amounts of clean, potable water may be added to obtain a workable consistency. To avoid texture or coverage variations, add the same amount of water to each pail. Don’t exceed 24 ounces (0.7L) of water per pail.
Application—Prime the surface with Master Wall® Primecoat or Sanded Primecoat tinted to match the predominate color of stone in the selected Superior Stone color. Allow Primecoat to dry a minimum of 12 hours prior to finish coat application.
Superior Stone Finish is typically applied in one or two coats, trowel applied with a stainless steel trowel. Apply the coating to the thickness of the aggregate taking care to avoid trowel marks in the finish surface. Let first coat dry prior to beginning a second coat. Smooth to match approved sample.
Contact Master Wall regarding spray application.
Clean Up—Tools and equipment can be cleaned with soapy water while the finish coat is still wet.
