- Application Equipment
Methods of Application: L&L 300 RCM Mastic can be brushed , rolled or sprayed. Rollers: 1" to 1½" nap. Airless spray equipment: Graco Bulldog 33:1 Pump # 237-435 fed by a Graco Monark 5:1 Transfer Pump # 224-350. Fluid hose requirements: 3/8" ID with ¼" ID whip-end section. Graco Gold or Silver Airless spray gun equipped with a .015" - .029" Graco Reverse-a-Clean tip. Spray equipment with specifications equal to or exceeding those listed above are available and may be used as well.
- Recommended Substrate Condition
Repair substrate and replace blistered polyurethane foam in accordance with the society of Plastics Industry (Spray Polyurethane Foam Division) recommended design consideration and guide specification. All surfaces to be coated must be clean, dry and free of dirt, oil, grease, mildew, rust, wax, chalking or peeling coatings and any foreign matter, which could prevent proper adhesion. Never apply to surfaces which pond water. We recommend L&L POWER PREP + as a pre-wash cleaner. It is fast and efficient and leaves no residue.

Technical Details & Test Data
- Viscosity
L&L 300 Mastic is manufactured in three thixotropic viscosities:
- "Light" brush, roller & airless spray grade
- "Standard" brush, roller & airless spray grade
- Trowel and palm grade
When choosing viscosity range, consider factors such as surface profile and porosity, required film thickness and application methods.

Storage & Handling
- Handling and Storage
L&L 300 RCM Mastic requires no mixing or thinning. Cleans up with soap and water when wet. Xylene required to remove dried material. Protect from freezing. Never apply at temperatures below +40°F. or when freezing temperatures are likely to occur before mastic cures. Discontinue application three hours before sunset. Do not apply when rain is likely to occur. Shelf-life: 19 months when stored indoors at +40°F. to +100°F. Keep container sealed when not in use. Read and understand Material Safety Data Sheets before using product.
