PetraWood™ was developed to permanently seal, waterproof, and harden wood products. PetraWood™ is water based, non-toxic and non-flammable.
PetraWood™ is NOT a WOOD FINISH, as it works only INTERNALLY to harden and densify the wood – thereby protecting it and extending the useful life of wood structures.
The proprietary catalyst in PetraWood™ allows it to penetrate through the layers of cells in the wood, where PetraWood™ reacts with both the acids and the alkali present in the individual cells of most woods forming an aero silica gel membrane on the surfaces of the cell walls. This membrane forms an internal seal and barrier against water and other causes of deterioration.
Over the 6 to 12 months following application, the aero silica gel membrane formed will hydrate and harden into glass petrifying the wood treated and is effective whether applied on surfaces that will be above or below grade.
PetraWood™ will not permanently alter the color, texture, or any other physical characteristic of the natural wood to which it is applied. If initial darkening occurs, just apply a wood brightener and rinse. Oxalic, phosphoric, and citric acid brighteners will bring the wood right back to pre-treatment coloration.
PetraWood™ provides a prepared surface 300% more effective than wood in the bonding of varnish, stains, paint and mastics. It leaves a “bondable” surface to which a wide variety of coatings, stains or paints can be applied, including polyureas / and urethanes.
Advantages
• Eliminates need for constant reapplication of wood finishes
• A one-time application will petrify the wood to the depth penetrated
• Leaves clear, natural finish with no surface film
• Helps wood retain and structural integrity longer
• Decreases or eliminates deterioration and weathering
• Enables easier ice and snow removal
• Increases resistance to grease, oils and acids
• Non-toxic, environmentally and ecologically friendly
• Easy clean up with water
Uses
• Cedar Shakes
• Decks
• Fence Posts, Rails and Slats
• Wood Shingles
• Piers
• Window Boxes, Frames and Sash
• Wooden Planters
• Anything made of wood needing a longer life
• Serves as a “primer” to increase the bonding and sticking of paint and surface coatings.
