Shell-Guard Concentrate is a combination of glycols and borate that must be mixed with an equal volume of water for use. The diluted solution is applied to bare wood and impregnates the wood fibers with the active borate ingredient eliminating and providing protection against wood decay fungi and wood consuming insects.
Like all borate-based wood preservatives the diluted Shell-Guard solution must be applied to unfinished bare wood. One application of diluted Shell-Guard Concentrate is permanent when exterior wood surfaces remain protected with one of our Lifeline exterior finish systems.
