Weight: 70lbs (32kg)

Working Time: Ready to use right from the pail after pre-mixing. Formulated for production application.

Drying Time: Varies by air temperature, humidity and surface temperature. Under normal room temperatures Superior Elastomeric Finish will firm set in 8-12 hours and fully set in 48-72 hours. Protect the finish from rain and temperatures less than 40F (5 C) for a minimum of 24 hours.

Application/Storage Temperatures: 40F (5C) to 110F (43C). Store out of direct sunlight.

Shelf Life: 2 years under normal conditions.

Application Procedure

Job Conditions - Air and substrate temperature for application of Superior Elastomeric Finishes 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. 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 14 days.

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 Elastomeric Finish. Substrates of brick, masonry or concrete should be leveled smooth using either Master Wall base coats or stucco.

Mixing - Thoroughly stir Superior Elastomeric Finish 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 color variations, add the same amount of water to each pail. Do not exceed 24 ounces (0.7L) of water per pail of finish.

Application - Apply a uniform thickness (about 1/16", 1.6 mm) of Superior Elastomeric Finish to the substrate using a stainless steel trowel. Spread evenly and then scrape the finish coat down to a thickness no greater than the largest aggregate in the material. Immediately float the finish coat using a plastic float to the desired texture. Always maintain a wet edge to achieve uniformity of texture and color.

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).

Finishes are intended for the approved substrates listed above and should not be applied directly to gypsum board or insulation board products.

Clean Up-Tools and equipment can be cleaned with soapy water while the Superior Elastomeric Finish is still wet.
