PENOFIN® penetrating oil finishes are formulated to enhance and protect the natural beauty of your deck. Your deck will look newer and last longer with proper care and maintenance. *Available in one quart and one gallon sizes.

Causes of natural wood aging:

Sunlight
Ultraviolet radiation breaks down the cellular structure resulting in a "graying effect."

Moisture
Water settles in the open cellular layers wherever there is a break and promotes rotting.

Temperature
Freezing and thawing, especially where water has penetrated the inner cellular layers, accelerates cellular deterioration.

Microorganisms
Mold and mildew are particularly common trouble makers. Green, black, or gray discoloration is caused by mildew colonization.

Particulate
Particulate matter comes in many forms such as dirt, soot, pollen, and food. These organic particulates provide nutrients for microbial growth and accelerate wood deterioration.
Inorganic stains may result from iron in nails or other hardware, darkening the surface. Lime found in mortar mixes may leach from adjacent brick or stonework and coat the deck surface causing a variety of staining.

Extractive Bleeding
Extractives, include tannins and other polyphenolics, colorings oils, resins, gums, etc. They contribute to such properties as color, odor, decay, and flammability. Water soluble extractives will cause stain discoloration. Non-water soluble extractives such as pitch and resin may bleed through the surface and harden there when the solvent evaporates.

Penofin First Step Prep Application Instructions
With plain water, thoroughly wet the surface and surrounding vegetation to remove dirt and avoid streaking. Apply First Step Prep to the wet surface with a brush or pump-up sprayer. Allow to set for 15-30 minutes, then rinse away with plain water while brushing with a stiff natural bristled brush. Rinse again and allow to dry thoroughly before treating with Penofin Exotic Hardwood Formula. In extreme cases, two applications of First Step Prep may be needed. Available in Quart or Gallon.
