The useful life will be increased two <br /> to three times. <br /> The easiest guide for estimating preservative consumption is <br /> t� figure absorption of approximately 1/2 gallon per cubic foot of <br /> wood; or 10 - 12 gallons will treat 1,000 board feet (1" to 2" thick) <br /> in a three minute cold soak. <br /> Brush or roller metho3: Tlie key to satisfactory treatment by , <br /> this met o is t e app ica.tion of liberal amounts of preservative <br /> in order to gain maximum penetration and retention. Use a natural <br /> bristle brush or a 3/4" to 1 1/2" nap roller, depending on the <br /> surface roughness. <br /> Coverage will depend greatly on the wood species, seasoning and <br /> texture. Smoother surfaces will require 225 to 250 square feet per _ <br /> gallon. For applications over rough surfaces, expect to get approxi- <br /> mately 100 square feet per gallon. Two applications are recommended <br /> with 24 hours between coats. <br /> Spray method: While this product may be sprayed, we do not <br /> recommen it. ATCO #1402 Copper Preservative is toxic to all fungi <br /> and plant liPe, ay well as termites and wood borers, Mist drifting <br /> or dripping onto plants or foliage may defoliate or kill them. Zf <br /> spray application is the only feasible method of apglying the pro- <br /> duct, use low pressure and a large orifice and avoid atomizing the <br /> liquid. Other precautions to minimize contact on undesirable sur- <br /> faces including the applicator, other humans and animals should be <br /> implemented. Coverage is approximately 200 square feet per gallon. <br /> Retreatment should be considered after three years, depending <br /> on the exposure. <br /> if it is desirable to paint the treated surface, it is best to . <br /> do so after the treatment has had some time to weather. Either <br /> water or oil based paints may be used. Weathered surfaces require <br /> 1 or 2 coats. Applications of paint within 72 hours of preservative <br /> treatment usually require two coats because the initial coat may • <br /> suffer some bleed-through. <br /> Clean tools, brushes, rollers, etc. with paint thinner. Remove <br /> from skin with waterless hand cleaner. <br />� <br />
