Wood Treatment



National Guardian Wood Treatment is a specially formulated penetrating sealer and conditioner which reacts with properties inherent in all wood and wood-based materials. Wood Treatment is an aqueous compound which works from the inside and becomes an integral component of the material. Wood Treatment provides the following benefits:

– Seals against water penetration and damage
– Aids in preventing damage from mildew
– Resists warping and cracking
– Resists insect damage
– Increases resistance to fire
– Improves adhesion of other coatings

National Guardian Wood Treatment is not a surface coating which will wear off or be affected by weather or ultra-violet radiation. Treatment with National Guardian Wood Treatment does not change the appearance of most wood species. As a non-toxic, non-flammable, odorless, clear, acid resistant compound, National Guardian Wood Treatment greatly extends the useful life of wood products and structures without environment impact.

The increase in fire resistance is a distinct advantage of National Guardian Wood Treatment over other methods and products. Wood Treatment will resist the de-laminating tendencies commonly associated with flame retarding compounds. By reacting with and altering the materials utilized by insects as a food source, Wood Treatment negates the damage of insect infestation.


National Guardian Wood Treatment should be applied to materials that are free of paints, coatings or other foreign materials. Pressure treated woods are acceptable for use with Wood Treatment and the moisture-proofing benefit of Wood Treatment will prevent the qualities of pressure treating chemicals from leaching from the wood.

New Surfaces
Usually require no special preparation, however all materials to be treated should be as dry as possible before application of Wood Treatment.

Extremely dense or old wood should be washed with National Guardian Pre-Treatment and allowed to dry prior to the application of Wood Treatment.


SHAKE WELL BEFORE USE. Do not dilute National Guardian Wood Treatment with other liquids or compounds. Use as supplied. Saturate the surface with Wood Treatment by brush, roller, mop or low pressure spray. Special requirements or volumes may be treated by immersion or dipping and treated materials should be stored to allow maximum air circulation.

Apply liberally and allow for full saturation. Vertical applications should be applied from bottom to top with approximately a three inch run-down. Treated materials should be allowed to dry for three to five days before the application of paints or stains.
