Internal Wood Stabilizer

Alternative for Waterproofing Wood …with zero VOC’s and zero hazardous ingredients.

Two initial coats of Internal Wood Stabilizer (IWS) provide PERMANENT protection from water absorption.

Permanently protect ecologically sensitive wood projects such as:

1. Raised bed garden boxes
2. Wood beehive boxes
3. Dog houses, birdhouses, or wood cages
4. Wood docks, decks, fences, or wood bridges
5. Wood greenhouses
6. Picnic tables, outdoor wood furniture
7. Wood or log playground structures
8. Wood siding, especially in coastal or wet climates
9. Any other bare untreated exposed wood to be sealed
10. Fence posts, retaining walls or any other wood that will be in constant contact with moisture.

How does it work?

Internal Wood Stabilizer is a clear watery liquid and must be applied to bare, unsealed, untreated wood intended for outdoor use. IWS absorbs and a chemical reaction occurs when it combines with the free alkali that exists naturally in wood. A waterproof gel forms deep within the pores. The gel hardens to hard silicate-like glass crystals which remain permanently imbedded deep within the wood which becomes so dense it can absorb little to no water. IWS does not wear off, never needs re-application and does not attract dirt and spores.

The IWS does not contain any UV inhibitors so the wood will eventually turn silver in color if exposed to sunlight. Our stain CAN be applied over the top of IWS, however, you'd only want to stain the exterior of a garden box, not the interior faces with exposure to dirt. While our stain may not penetrate quite as deeply over the IWS, the crystalline structure formed inside the wood helps stains and paints adhere, so only one coat of stain may be needed.

Coverage : 1 gallon of IWS will double-coat approximately 100 sq ft on rough sawn wood or 125 square feet on smooth wood (length X width to calculate square feet)
