General—Air and substrate temperature for application of Lumia 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 Lumia.
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 Lumia 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 up to a maximum of 6 ounces (0.2L) but is not normally required. To avoid color inconsistencies only use product with the same batch numbers for a section or elevation.
Application—Prime the surface with Master Wall® Primecoat or Sanded Primecoat tinted to match the predominate color of stone in the selected Lumia color. Allow Primecoat to dry a minimum of 12 hours prior to finish coat application.
Trowel Application—Apply the Lumia Finish to the clean, dry and cured base coat with a stainless steel trowel about 1/16″ to 1/8″ (1.6-3.2 mm) thick. Trowel finish uniformly onto the primed surface. Lightly float with a plastic float eliminate trowel marks and irregularities and expose the mica chips. Clean the float often during this process, making several passes to produce the final texture and appearance.
Clean Up—Tools and equipment can be cleaned with soapy water while the finish coat is still wet.
For Professional Results
Apply finish coats away from direct sunlight.
Surfaces exposed to the weather must be sloped (6:12 minimum).
