Frequently Asked Questions

Can Penofin be applied over another wood stain?

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

I want to put a clear wood finish on my deck/home. What do I use?

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

After applying Penofin wood stains, I have areas that are shiny and areas that are not. What is wrong and what do I do to fix it?

This indicates overapplication of the wood stain. 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.

How long will the wood stain last on my deck/house?

On a horizontal surface, Penofin 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...

If I apply one color of Penofin wood finish (Example: Transparent Redwood) and I want to go with another color of Penofin wood finish when reapplication is needed (Example: Sierra), can I do that?

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.

Do you have anything to cover pressure-treated wood?

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

How can I tell if the wood is too hot to apply Penofin wood finishes?

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

How does it compare to other wood stains on the market?

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

What do I do if my wood has mildew growing on it?

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

Does Penofin wood stain bead water?

Water beading is accomplished in most wood 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 does not need to bead to protect.

What about my deck getting wet?
