Sealers, Stains, & Finishes

NBS 30 Wood Insect Repellent

Designed for use in exterior coatings, Outlast's NBS 30 will inhibit insects such as ants, cockroaches, beetles, mites, spiders, fleas, ticks, silverfish, dirt daubers, bees and wasps from burrowing through exterior surfaces. NBS 30 is soluble or dispersible in commercial oil and water based exterior paints or stains. It's also a great insect control spray by dispersing it in plain water for a gentle, botanical approach. NBS 30 is NOT an insect killer and is not intended for control of termites or other wood ingesting insects.
