High performance, one-step, non-toxic wood stain-sealer

Vermont Natural Coatings Exterior Penetrating Stain with PolyWhey technology is a low-odor, durable, element-repelling, semi-transparent stain and topcoat for the outside of raised garden beds, wood siding, decks, fences, furniture, and other outdoor wood surfaces. It may be used on new, pressure-treated and weathered wood (pressure treated wood should sit for 6 mo to a year before application).

NOTE: Image swatches on our website are on Pine. If you have a different specie of wood, the appearance may be different. Please order a sample to confirm the actual appearance on your wood.

The natural strength of whey protein makes Vermont Natural Coatings Exterior Penetrating Stain a protective, environmentally safe finish for all exterior wood applications. It is non-toxic, has low odor and contains no biocides, fungicides or anti-microbial agents. The pigments act as a natural UV inhibitor.

By using recycled whey protein, Vermont Natural Coatings eliminates the need for heavy metal driers, toxic co-binders and carcinogenic solvents typically found in wood finishes. The whey used in this product is a natural by-product of the cheese-making process used by Vermont farmers. It surpasses every national, regional, state and county air quality regulation.

NOTE2: This product requires a wet on damp two-coat application. This means apply the second coat while still damp, but BEFORE it dries. If you wait too long and the first coat dries, you will not be able to apply the second coat—it will just bead up. How long you wait in between coats depends heavily on temperature, humidity and wind conditions. If it's windy and >80 degrees it will dry in a few minutes so you will need to work faster and in smaller areas 3' x 3' at a time before moving to the next section. Best practices require application in shade and during cooler part of the day. Cooler damp conditions mean it will dry more slowly and you will have more time in between coats.

NOTE3: Not recommended for use over super dense woods such as Teak, Ipe or Garapa/Brazilian Ash.

NOTE 4: It's the pigments in the different colors that block UV rays and protect the wood much longer. Using the Caspian Clear will not hold up as long.

NOTE 5: Can be applied over oil-based stain or finish, as well as other water-based finishes. HOWEVER, the product can only be applied over other finishes that have been sanded. The Exterior Penetrating stain NEEDS to be able to penetrate the wood, which it can do IF an old finish has been sanded, but cannot if the film build of the original finish remains.

Apply with brush, paint pad, or spray. Under normal conditions treated wood will be fully cured in 48 hours. One gallon will cover approximately 200 sq. ft on rough sawn-400 sq. ft. on smooth wood depending on porosity of wood. Colors include: Caspian Clear, Autumn Red, Lakeside Cedar, Acorn Brown, Sterling Gray, Royal Cherry, Balsam Green, Bison Brown, Brackish Brown, Golden Cedar, Coastal Gray and Granite Gray.
