Job Conditions – Air and substrate temperature for application of Aggre-stone must be 50°F (10°C) or higher and must remain 50°F (10°C) or higher for a minimum of 24 hours. Dry time will vary by temperature and humidity. 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. All exterior surfaces must be sloped a minimum of 1:2. 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. Brick, masonry and concrete should be leveled either with stucco or Master Wall base coats prior to application.
Priming – As the Aggre-stone binder is translucent, priming with Primecoat or Sanded Primecoat is recommended. Primecoat should be tinted to the predominant color of the Aggre-stone. See Primecoat Data Sheet for additional information, allow to dry a minimum of 12 hours before applying Aggre-stone.
Mixing – Thoroughly stir the Aggre-stone finish for one minute using a heavy duty 1/2″ (12.7 mm) drill at 400 – 500 rpm and a heavy duty mixing paddle. Do not over mix. Small amounts of clean, potable water may be added to obtain a workable consistency. Do not exceed 24 ounces (0.7L) of water per pail. Do not add accelerators or retarders to the mixture.
Over the primed surface—Aggrestone 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.

Clean Up—Tools and equipment can be cleaned with soapy water while the Aggre-stone is still wet.
