Aggrelime is available in standard or custom colors, Aggrelime may be applied over Master Wall® Base Coats or stuccos or interior surfaces. Aggrelime is available in five-gallon (19L) pails and is typically troweled onto the wall surface with a stainless steel trowel and finished with a variety of techniques.

Master Wall Base Coats
Prepared & Base Coated Surfaces of:
Interior Drywall made ready for paint
Others approved in writing
Job Conditions - Air and substrate temperature for application of Aggrelime must be 50°F (10°C) or higher and must remain 50°F (10°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. High temperatures will reduce working times, Low temperatures and/or high humidity will extend working, set and dry times.
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 7-14 days.
Interior Drywall- Prime surfaces with Sanded Primecoat primer prior to finishing. Bond test prior to application on previously painted surfaces.
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 Aggrelime using a heavy duty 1/2" (12.7 mm) drill at 400 - 500 rpm and a heavy duty mixing paddle. Small amounts of clean, potable water may be added to obtain a workable consistency. To avoid unintended color variations, add the same amount of water to each pail. Do not exceed 3 ounces (0.1L) of water per pail of finish.
Application — Apply Aggrelime to match the approved sample texture or effect using the selected tools and techniques. Extra care is needed to ensure a very smooth base coat has been achieved as the finish will not cover wall irregularities. Using a stainless steel trowel, apply Aggrelime to a uniform but tight thickness. Allow this first coat to dry to the touch and apply a thin second coat and allow it to take up. Floating or finishing options:
Float the finish lightly with a Lexan float. Produces a lightly mottled, fine finish.
After the second coat finish has taken up slightly, trowel again in one direction with a stainless steel trowel. Produces a super smooth finish.
For consistency, use the same methods and application techniques across the entire wall surface. The Aggrelime finish is intended to replicate the appearance of natural limestone. The application technique will have larger flat areas with small pit marks and possibly burn marks and varied color/texture conditions. This variation is intentional and part of the properties of this finish. For best results two thin coats are recommended.
For Professional Results
Apply finish coats away from direct sunlight. Cold joints or color variations can occur if the finish dries too quickly.
Consider priming stucco surfaces with Primecoat to even out finish absorption.
Surfaces exposed to the weather must be sloped (6:12 minimum).
Do not apply to gypsum board or insulation board products.
Clean Up—Tools and equipment can be cleaned with soapy water while the Aggrelime is still wet.
