Chevron Shingle Oil is a straw colored, low viscosity oil designed for use as a shingle or shake dressing for shake roofs, wooden fencing, wood siding, and log homes.
Chevron Shingle Oil penetrates the wood surface to enhance or replace natural oils and resins leached out by cyclical exposure to sun and rain. Although Chevron Shingle Oil retards the aging process, it will not renew wood that is already weather damaged.
Loose dirt and debris should be removed before the oil is applied. The roof should be hosed with water 24 hours prior to application to lessen the possibility of over application. Alternatively, a licensed contractor can power wash the roof thereby removing weatherdamaged wood, allowing oil to absorb into new wood.
Chevron Shingle Oil may be applied by brushing or spraying. The typical application rate is 150-300 square feet per gallon. Application rate depends on the type of wood and the rate at which the oil saturates the wood.
Do not overapply — Over application may lead to shingle or shake "cupping" and the presence of oil in rainwater runoff.
Do not add color pigments — as they will lump and settle out.
Do not walk on treated surfaces — Chevron Shingle Oil is a petroleum oil and is slippery.
Do not use on flat surfaces, such as decks. Properly licensed contractors may add certain chemicals, such as antifungal agents and other substances, to Chevron Shingle Oil. Be sure to find out what safety or health restrictions may apply to these additives.
