Penofin Common Questions

We’ve gathered the most commonly asked questions about Penofin. If your question isn't answered here, please contact us with any questions you may have.

Application

How much Penofin do I need for my project?

Penofin will cover 150 – 200 square feet per gallon on rough surfaces and from 250 – 300 square feet on smooth surfaces.

What do I do to prepare the wood for a Penofin application?

The manufacturer recommends that you use Penofin Pro Tech wood care products. The cleaner and brightener both come in powder form and are easily mixed with water. They take just minutes to apply and are environmentally safe. The Cleaner is an excellent product to use for regular maintenance or if the wood you are staining is susceptible to mildew or algae growth. Let the wood dry for at least 24 hours and then apply Penofin.

Can Penofin be applied over another stain?

Because Penofin is a penetrating finish and different stains contain different ingredients you cannot be sure that Penofin will penetrate through the existing finish. It is for this reason we recommend that Penofin be applied to clean, bare, dry wood. Penofin can be applied over an existing Penofin finish.

How hot or cold can it be when applying Penofin?

Generally speaking you should not apply Penofin outdoors at temperatures under 45 degrees or above 80 degrees. A good rule of thumb when applying Penofin is to trust your own temperature gauge. If you put your hand on the wood and it is uncomfortably hot, it is too hot to apply Penofin. The product may flash (like oil in a hot pan) and dry on the surface. This will eventually cause darkening, and the coat will chip and peel. If your nose is cold, it is too cold to apply Penofin. The product will not penetrate the wood as efficiently at colder temperatures and the application will not last as long. Short sleeve weather is the ideal temperature range for a Penofin application.

How long will it take Penofin to dry?

Penofin dries to the touch in 4 hours and is serviceable (You can have a party) in 12 hours.

Should I apply Penofin if rain is in the forecast?

Ideally you should apply Penofin 24 hours after a rain and rain should not be expected for 24 hours after application.

It rained and I have these little spots all over my deck. What should I do?

Simply wash the wood with a solution of 1 Cup Penofin Pro Tech Cleaner Step 2 to a gallon of water. This can be done even while the wood is still wet. Apply the cleaning solution to the wood and agitate the affected area for approx 15 minutes with a stiff brush. Rinse thoroughly and let dry for 24 hours. If the surface appears blotchy apply a light coat of Penofin to even out the appearance.

Do I really have to wipe the wood after applying? My deck is sticky, tacky, shiny and dark.

This is the grand daddy of all application questions and the answer is a resounding YES! Penofin is a penetrating finish that penetrates into the surface of the wood. That is where it belongs and does its best work. The surface of the wood must be wiped thoroughly with nap free cloths to assure that no Penofin dries on the surface of the wood. If you allow Penofin to dry on the surface of the wood it will turn sticky and tacky and eventually peel off the surface because it is not a surface coating. It will also interfere with the cure of the product that has penetrated into the wood causing the product to fail to protect the wood fibers.

I didn't wipe the wood after applying and now it's sticky and tacky. What can I do to resolve this issue?

Penofin Pro-Tech Cleaner applied according to directions will clean the finish, once dry. If the wood appears blotchy apply a light coat of Penofin according to the directions on the can remembering to wipe.

How do I clean an old wood surface before applying Penofin?

Use PENOFIN’S THREE-STEP SYTEM to restore and prepare your wood surface for perfect results!

If the wood was previously finished with a brand other than Penofin Oil Wood Finish, use Step #1 Pro-Tech Stripper. If the prior finish was a 100% acrylic water-based product, use a conventional paint stripper. This fast-acting, oil-base finish and paint remover works in thirty minutes! Follow the directions on the label for easy stripping every time!

Also use Penofin Pro-Tech Stripper to ensure proper penetration of Penofin Oil Wood Finishes. To test the wood’s absorbency, sprinkle a few drops of water on the surface; if water does not penetrate after a few minutes, stripping with Penofin Pro-Tech Stripper is necessary.

Next apply Step #2 Pro-Tech Cleaner to remove mold, mildew, or surface dirt. Finally restore the wood back to its original mill-bright color by using Step #3 Pro-Tech Brightener. This easy-to-use wood brightener removes the gray appearance caused by wood tannins.

Old wood: Old wood is more porous and may require more stain to cover the surface. Average coverage per gallon is 250 square feet. Consider that older wood may absorb more finish when buying for the project.

How do I clean a new wood surface before applying Penofin?

Use Protech Cleaner to remove surface dirt and kill mold and mildew spores that may be living in your new wood. Follow the easy directions on the label for fast and effective cleaning.

It is our recommendation to apply a light coat of Penofin Oil Wood Finish to your wood surface while it is "seasoning". Why let the damage occur? Protect your investment from the beginning!

If you have allowed the wood surface to "season" or age before finishing, use Protech Brightener to remove any discoloration caused by tannins. Allow the wood to dry for ideal penetration of Penofin Oil Wood Finish.

How do I apply Penofin for hardwood?

One gallon of Exotic Hardwood Stain provides 300-400 square feet of coverage.

Apply a light coat to clean, dry, unfinished wood by using a pump sprayer or a good quality china bristle brush. Pre-sanding the surface with 60-to-80 grit sandpaper is recommended by some hardwood associations. Wait 20 to 30 minutes for the stain to absorb and wipe the entire surface with a nap-free cloth. Do not over apply or surface will become tacky or sticky. Caution: Do Not Apply to Wood That is Hot to the Touch. Be sure to allow 12 to 24 hours before using. Reapply Penofin several times the first year for maximum surface penetration as soon as wood appears dry or faded. The wood fibers become fully protected and the maintenance will become less frequent over time.

What are some good tips for applying interior wood stain on cabinets, furniture or flooring?

Apply Penofin to a small area. First, sand the area with a 400 to 600 grit wet/dry sandpaper. Be sure to sand with the grain and keep the area wet with PENOFIN. Wipe the area dry and repeat the process until grain is filled and desired patina is achieved. Buff to a polish with a clean, soft cloth. If desired, a polyurethane varnish or lacquer may be applied over PENOFIN after one week.

Product Questions

Why should I choose Penofin over other stains?

Penofin's formula penetrates deep into the woods surface. It coats the individual fibers of the wood, allowing moisture to pass in and out of the wood allowing the wood to breathe. Penofin uses the best, most safe raw materials available and do not compromise for the sake of cost.

All Penofin stains contain Brazilian Rosewood Oil which is a strong, flexible, water-resistant, mildew resistant oil that is sustainably harvested from the seeds of the Brazilian Rosewood tree.

A Penofin application is easy to maintain when applied according to directions. You will never see a surface film when using Penofin, so you will never see cracking, bubbling or peeling. You will also never need to strip or sand again! Simply clean the wood thoroughly, let dry and apply a light coat to any areas of the wood that may show wear and tear. It will easily blend in with the rest of the application.

Why does the lid say not to store in the can?

Penofin recommends that you buy only enough Penofin to complete the job. Once the factory seal is broken it is hard to re-seal a container. Allowing air into the container will dissipate the solvents causing the remaining oils and resins to gel. Unopened Penofin can be stored indefinitely in the can.

How long will Penofin last on my wood?

On a horizontal surface you can expect Penofin 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 exposure.

Can I apply a polyurethane coating over Penofin?

It is not necessary to put any kind of coating over Penofin. If you wish to put a coating over the wood for any reason, allow 7-10 days for the Penofin to completely cure before beginning. At that point, a polyurethane coating will not hurt the wood or the stain.

If you plan on applying Penofin to an area that is already covered in polyurethane or other coating, it is necessary to strip off the coating and clean the wood with Penofin's 3-step cleaning system before applying Penofin Penetrating Oil.

What is a suitable replacement for Penofin Pro-Tech Composite Cleaner Restoration System?

Penofin no longer offers Penofin Pro-Tech Composite Cleaner. The Penofin Pro-Tech Cleaner Step 2 Restoration System is a suitable replacement for cleaning composite decks.

Safety

What is spontaneous combustion? Why do I have to soak the oily rags in water?

Spontaneous combustion is a phenomenon in which a substance unexpectedly bursts into flame without apparent cause. In ordinary combustion, a substance is deliberately heated to its ignition point to make it burn. Many substances undergo a slow oxidation that, like the rapid oxidation of burning releases heat. If the heat that is released cannot escape the substance, the temperature of the substance rises until ignition takes place. Spontaneous combustion often occurs in piles of oily rags, green hay, leaves, or coal; it can constitute a serious fire hazard.

What is VOC?

VOC stands for Volatile Organic Compound, which is a drying agent that causes off gassing into the environment.

Where can I find MSDS Sheets?
