Product Performance Warranty
PENOFIN® exterior finishes are warranted to perform when applied to wood surfaces according to label instructions. For Blue Label Penofin expect 2 - 5 years on vertical surfaces, 1 - 2 years on horizontal surfaces depending on use and weather exposure. We recommend preserving the beauty of your horizontal surfaces by staining every 9 - 24 months.
Maintenance
- When you use Penofin, maintenance is a snap. Because Penofin is a low-solid product, there is no stripping or sanding necessary. Simply wash the surface with water and a mild detergent. Allow your wood surface to dry completely, approximately 48 hours before application.
- Follow the application methods listed on the previous page for a fresh and beautiful wood surface.
Coverage
Coverage depends on application method, texture, and moisture content of wood. Coverage is less on rough surfaces, more on smooth surfaces. Average coverage is 175-300 sq. ft. per gallon.
Cleanup
- Penofin is an oil-based product. Clean brushes and other application materials with mineral spirits or paint thinner.
- AVOID SPONTANEOUS COMBUSTION of oily rags. Soak all used cloths in a covered metal bucket of water, ensuring the cloths are completely covered with water. Cover until they can be properly disposed at your local hazardous materials drop-off.
Hardwood Application
Use a brush or sprayer. Brushing gives best results. Brush thoroughly and back brush Penofin into the wood leaving no excess. Wipe entire surface after 20-30 minutes with a nap-free cloth. Do not allow film to develop on wood surface. Apply when there is no chance of rain during the process or during the twelve-hour drying time. If rain occurs spots may develop on wood surfaces. Do not apply in direct hot sun! A minimum air temperature of 45° is required during application and drying time.
Repeat this application within 3-6 months and again within 10-12 months. Over time the wood fibers will become fully protected and maintenance will become less frequent. Product should be applied more often to horizontal areas and also areas with high ultra-violet exposure or heavy traffic. Store all oily cloths in water in a metal bucket until properly disposed.
