PenaShield® Penetrating Fungicide, Termiticide and Preservative is a ready-to-use borate-based wood preserver that kills and prevents termites, carpenter ants, wood boring beetles and decay fungi. PenaShield is a water-soluble treatment containing proprietary penetrants that allow it to diffuse quickly and thoroughly into wood.

PenaShield is great for treating decks, fencing, wood-working projects, wooden play structures, sheds, and more. It can also be applied to roofs after old shingles have been removed. Apply PenaShield to pressure treated and/or to older wood after it has been cleaned. PenaShield should always be applied before sealing or painting. PenaShield can be used to treat any bare wood you want to last when used according to label instructions.
