We are often asked what makes PENOFIN different from or better than other products, so we have compiled a list of the most common questions about PENOFIN products.

Q. Can PENOFIN wood finish be applied over another wood stain?

A. No, not without proper surface preparation. Recommendation is to clean surface and remove previous finish, usually by use of a pressure washer or sanding.

A. Our only clear finish is for interior use only. We would suggest the transparent finish designed for the type of wood you want to coat. (Examples: Cedar/Marine for cedar or teak; Transparent Redwood for redwood.)

A. This indicates overapplication. In most cases, washing the surface with a solution of TSP (Tri-Sodium Phosphate) and water, (with some scrubbing) after seven days drying time, will correct the problem.

A. On a horizontal surface, PENOFIN wood finish may be expected to perform for an average of 9-18 months and 3-5 years on a vertical surface. The time will vary depending on the percentage of sunlight, weather etc...

A. Yes. All PENOFIN wood finish 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.

A. Yes. Allow 7-10 days drying time for surface to be completely dry and cured. Both water- and oil- based products can be used.

A. Yes. PENOFIN has a gold-line of interior finishes.

A. No. PENOFIN is not a food-grade product.

A. Yes. With PENOFIN.

A. Approximately seven to ten days, depending on the weather.

A. All PENOFIN wood finish colors can be used on any type of wood. However, Chestnut and Sable blend out the green the best in pressure treated lumber and give it a natural wood tone.

A. If the surface is hot to the touch it is probably too hot to apply PENOFIN wood finish. Do not apply PENOFIN wood finish in direct sunlight. Product can flash and dry on the surface without penetrating.

A. Look at PENOFIN's blotter tests. PENOFIN wood finish penetrates better than anything on the market. It is the only product with Brazilian Rosewood oil. PENOFIN wood finish is one of the few wood finish products on the market containing transoxide pigments, the colorant developed to give automobiles their tough finish.

A. Clean with a solution of 50% bleach and 50% water with a small amount of detergent added to remove and kill the mildew spores.

A. Water beading is accomplished in most stains by adding wax (paraffin). As soon as you get one hot day your finish will no longer bead water because the wax melts. Penofin wood finish does not need to bead to protect wood.

A. There is nothing wrong with your wood getting wet (it was a tree). However, standing water can lead to rot.

A. 30 to 60 days depending on weather, humidity, etc.

A. WEATHERBLASTER contains ingredients common to fertilizer and can burn your plants. Just rinse with plenty of water and it will be fine.

A. WEATHERBLASTER will not remove old finishes. WEATHERBLASTER removes the gray tannin from wood bringing back the mill-bright beauty.

A. Use the red tip (1/4 GPM) for transparent PENOFIN wood finish and WEATHERBLASTER, the blue tip (1/3 GPM) for PENOFIN mist tones and the yellow (1/2 GPM) for heavier applications.

A. The new product has a different type of solvent and no longer contains 1,1,1 trichloroethane, otherwise, the products are identical. They contain the same colorant, mildew, and ultraviolet protection and Brazilian Rosewood Oil.

A. PENOFIN needed to change the drying agent in its VOC formula in order to comply with new VOC regulations.

A. Yes and more. The new dryer in the VOCII formula enables PENOFIN to offer an interior line in the VOC compliant products. So, you can also obtain Natural, Medium Walnut, Dark Walnut, and Appalachian Oak interior PENOFIN.

A. Absolutely. The two VOC products are completely compatible and can be used side-by-side. The two formulas can even be mixed together.

A. Yes, you can apply the VOCII formula with brush, sprayer, or stain pad. It has a little more viscosity and takes slightly longer to dry.

A. The VOCII PENOFIN formula cleans up with mineral spirits or paint thinner.

A. Yes.

A. The new VOCII PENOFIN is better smelling than the old VOC formula and doesn't linger as long after application.

A. The new VOCII Penofin still outperforms the competition.

A. Yes, this product is an oil-based product and care should be taken during application. See the Material Safety Data Sheet and the label for specific instructions.

A. The VOCII formula performs just as well as the old VOC formula.

A. Lab testing and field testing was performed and test results showed that the new VOCII PENOFIN formula actually outperforms the old VOC product in some applications.
