Area Preparation Surface must be clean and free of all dust, dirt, mildew, oil, loose wood fibers and other contaminants. Use an exterior wood cleaner to prepare new wood prior to coating, and to clean and restore weathered, dirty surfaces and remove mildew stains. After rinsing, ensure surface is free of standing water. Remove grade stamps or pencil marks by sanding. WARNING! If you scrape, sand, or remove old paint, you may release lead dust or fumes. LEAD IS TOXIC. EXPOSURE TO LEAD DUST OR FUMES CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a properly fitted NIOSH-approved respirator and prevent skin contact to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the USEPA National Lead Information Hotline at 1-800-424‑LEAD or log on to www.epa.gov/lead. Follow these instructions to control exposure to other hazardous substances that may be released during surface preparation. Application Details Surface should be dry or damp to the touch - but not visibly wet. Remove any standing water. Avoid staining in direct sunlight or on hot surfaces. DO NOT THIN. Stir thoroughly and often during use. Apply to a small area and allow to dry to ensure acceptable appearance and penetration. Intermix containers to ensure color uniformity. Apply one thin coat with a high quality brush, roller, paint/stain pad or by spray equipment. When rolling or spraying, always back-brush for best results. To help avoid lap marks, apply to only a few boards at a time, and maintain a wet edge. Apply when no precipitation is expected for 24 hours, and when air and surface temperatures are 35°F to 90°F (2°C to 32°C) and will remain above 35°F (2°C) for the next 24 hours. Drying Time Normally dries in 24 hours when applied in temperatures of 50°F (10°C) to 85°F (29°C). High humidity or low temperature application may prolong drying time. Coverage Approximately 250 to 350 sq. ft. (23.2 to 32.5 sq. meters) per gallon (3.78 Liters) depending on application, wood texture and porosity. Cleanup Clean brushes and tools with warm, soapy water.
