Fiberboard, wood, and wood products coated with PyroCoat EX1 produce a smooth, hard, fire resistant surface. With proper curing or the application of a top coat, the coating becomes water resistant and washable. Since the product is completely inorganic it will not burn and, therefore, no toxic or corrosive gasses are given off.
The dried coating will sustain heats in excess of 3,000° F.

- Recommended Applications
PyroCoat EX1 may be applied by spray, dip, roller, or brush. It must be applied in several coats with no more than 4 mils of wet coating per layer. It is important that the coating is dry before a new layer is applied. The total amount of coating will depend on the degree of fire resistance required. A typical application level to achieve good fire resistance over wood would be two coats at about one gallon of PyroCoat EX1 per 100 square feet per coat. For the coating to be water resistant, it must be heat cured at 248 F to 266 F for two hours.
The temperature should not exceed 275 F or it will begin to expand forming a porous, bubbled texture. This is due to the release of a large quantity of water of hydration. If heating the coating to achieve water resistance is not practical, a light coat of FRC-EX5 or PyroCoat EX12 may be applied over the PyroCoat EX1.
PyroCoat EX1 may be pigmented. Before adding pigment, check with PyroTech.NOTE: While PyroCoat EX1 functions well on many materials, it does not provide fire resistance to every product. The buyer accepts liability for determining whether the product is suitable for the buyer's intended use.

Storage & Handling
- Storage and Handling
The recommended storage temperature for PyroCoat EX1 is between 50° F and 100° F. If the product is stored below freezing, it should be brought back slowly to room temperature and stirred.
PyroCoat EX1 is alkaline (pH 11.2) and appropriate precautions should be taken when handling. Wear a protective mask, gloves, and safety goggles to avoid potential nasal, throat, skin, or eye irritation while applying the product.
Before using PyroCoat EX1 it must be stirred well to redisperse.
PyroCoat EX1 can only be applied to surfaces which have not been previously painted or sized. Before application, it is best to clean and sand the surface. Clean all equipment immediately following use with warm water and mild detergent.
