Freshly treated lumber should be protected from rain. For lumber 2 inches or less in thickness, one gallon of Sta Brite P is combined with 200 gallons of water. Stronger solutions are needed for lumber thicker than 2 inches, for tightly bundled lumber, sur faced wood and for prolonged exposure to adverse conditions, such as high humidity or frequent rain, or when ultra low volume applicators are used to apply the solution. Surfaced lum ber normally retains only one-half as much fungicide solution as rough cut wood and hence needs a concentration of double the Base Strength to deposit the necessary amount of fungicide on the wood. Dilute 1 part Sta Brite P with 10 parts of water or 1 gallon of Sta Brite P with 15 gallons of mineral spirits or equivalent solvent.
Mild agitation is necessary during the dilution process.
The best results will be obtained if wood to be treated is immersed for 3 minutes or longer. Allow at least 1 hour between applications. Make certain all surfaces are fully treated to obtain the maximum benefits. Less paint is needed over wood treated with this water repellent wood preservative. Dilute 1 part Sta Brite P with 10 parts water or 1 gallon of Sta Brite P with 15 gallons of petroleum solvent.
