Do you recommend a 1:1 ratio for existing areas of wood decaying fungus? If so, a 1:1 ratio will take a lot of chemical to treat the whole crawl space under my house - is it ok to spot treat with 1:1 ratio only affected areas and then spray 5:1 ratio for prevention everywhere else? And would I need to wait for spot treatment to dry first before spraying 5:1 ratio or could I just spray around it? Final question, should I spray first and then come back later and put down my vapor barrier? (I saw comment about spray being sticky.)
When using Boracare to treat for an active infestation of wood fungus it is applied at a 1:1 ratio for wood that is 4" thick or greater. Use a 3:1 dilution ratio for wood less than 4" in thickness. You can spot treat the areas that have active fungus and then use the 5:1 for future prevention in the non effected areas. You should be sure to address the moisture issue in the area before or during treatment of Boracare and apply a vapor barrier after the product has dried. Please see the product label for complete application instructions.
