A. Yes. With PENOFIN.
Q. I want to put a clear finish on my deck/home. What do I use?
A. We have a Clear in both Blue and Red Label. The Clear tone products allows the wood to weather naturally. Our complete product line was formulated to show the beauty of the wood.
Q. After applying PENOFIN, I have areas that are shiny and areas that are not. What is wrong and how do I fix it?
A. In most cases this indicates overapplication. After 24 hours drying time, wash the surface with Pro-Tech Cleaner; with some heavy scrubbing this should correct the problem. Rinse well. Power washing at 600 psi may also be used.
Q. How long will it last on my deck/house?
A. On a horizontal surface, PENOFIN Red Label may be expected to perform for an average of 9-24 months, and 2-5 years on a vertical surface. The time will vary depending on the percentage of sunlight and weather. Our premium lines are formulated to last longer.
Q. If I apply one color of PENOFIN (Example: Transparent Redwood) and I want to go with another color of PENOFIN when reapplication is needed (Example: Sierra), can I do that?
A. Yes. All PENOFIN colors contain the same ingredients, just different amounts of colored pigments. However, you will not be able to make the surface lighter by applying a lighter shade. As always, you should test a small area before use.
Q. Can PENOFIN be applied over another stain?
A. No, not without proper surface preparation. Recommendation is to clean surface and remove previous finish, usually by a pressure washing or sanding. The exception is Penofin over Penofin.

A. Penofin dries to the touch in 3 hours and is serviceable in 12 hours; it is fully cured in 7 days.

Q. How can I tell if the wood is too hot to apply PENOFIN?
A. If the surface is hot to the touch, it is too hot to apply PENOFIN. Be particularly careful in the heat of the day. Product can flash and dry on the surface without penetrating.
Q. What do I do if my wood has mildew growing on it?
A. Use Penofin Pro-Tech Cleaner.®
Q. Does PENOFIN bead water?
A. No, it does not need to. Penofin has no wax by-products. Moisture passes through the wood as vapor. No warping, cracking, or peeling.
Q. What about my deck getting wet?
A. There is nothing wrong with your wood getting wet (it was a tree). However, standing water can lead to rot. PENOFIN will help to protect your wood by coating the wood fibers.
Q. How long should I let my new deck season before I apply PENOFIN?
A. We recommend applying PENOFIN immediately without allowing the wood to season for maximum protection.
