- Applications & Coverage
- Apply Prep Coat Plus with a stainless steel trowel to achieve a minimum dry thickness of at least 2.0 mm (1 /12 inch) and embed DuROCK Fiber Mesh as per system specifications. This may require two passes, allowing the first coat to cure sufficiently to be dry and firm to the touch before application of the second coat. Applied as an adhesive, Prep Coat Plus shall be rendered with a notched trowel, conforming to the adhesive pattern delineated in the system specifications.
- Substrate must be clean, dry, and free of cracks or loose material. Surface and ambient temperatures must be at least 4°C (40°F) a minimum of 24 hours, and must remain so until Prep Coat Plus has dried. Do not apply Prep Coat Plus in direct sunlight at temperatures exceeding 30°C (86°F) and protect from winds exceeding 25 km/hr (15 mph) as well as precipitation for at least 24 hours.

- Storage & Mixing
- Store Prep Coat Plus above 4°C (40°F) and below 40°C (104°F), off the ground and in a dry place away from direct sunlight. Employ temporary protection measures as needed. Under no circumstances shall Prep Coat Plus be permitted to freeze.
- Using a stainless steel or corrosion resistant mixing blade and power drill, mix one-half pail of Prep Coat Plus with 10 kg (22 lbs) Type 10, 20 or 30 Portland Cement. Mix at 400 – 500 rpm, ensuring not to induce air into the product, until a uniform consistency is attained. Let the mixture stand for 5 minutes, then re-mix before use.
- Up to 250 mL (8 oz) of potable water can be added to a full mix of Prep Coat Plus to adjust workability in hot temperature conditions. Accelerators and other additives are prohibited and will void warranty. Discard any material that has begun to stiffen.
