Benefits of pressure treatment vs coating:

  • Pressure treatment penetrates into the cell structure of wood while surface treatments may remain on top of the wood.
  • Pressure treatment will not chip, peel, flake, or crack; surface treatments may have some or all of these issues.
  • Fire retardant treated wood provides fire protection to all 4 sides of the lumber and plywood. Coatings may only cover one side of the lumber or plywood.
  • Pressure treatment has been used in constructing FR trusses for many years. Coatings may impede truss plate connections.
