Sashco Penetreat 3.5 Gallon - Powder Concentrate Sashco's PeneTreat is a borate-based log home preservative that protects against wood-ingesting insects and rot. It comes in a powder concentrate form, so it is easy to mix. It is also environmentally friendly, safe for people, plants and pets. It contains no glycols, but penetrates as deeply, and offers the same protection as glycol based borates. When sprayed or brushed onto bare wood, PeneTreat forms a protective shell to defend against rot and wood-ingesting insects. It is easy to use and EPA Registered.
You can use penetreat on Interior and exterior log surfaces. Please note that PeneTreat will only work when applied to bare wood.
