A unique solution for trees with damaged limbs or trunks! Tree Bandage penetrates into the wound and forms a glassious covering that actually becomes part of the tree. Non-toxic and non-hazardous with zero VOC, the water-based formula will not harm the tree or bush. When applied, the silica in Tree Bandage forms a silicon dioxide (quartz) protective bandage. Only minutes after application, the bandage begins forming. Within a week, the bandage is usually completely hardened, allowing calluses to form over the wounded area. Immediately after trimming or pruning, apply Tree Bandage using a brush or sprayer (when treating large areas or shrubs). Two or three applications may be required to fully cover the wound area. Coverage is 100 square feet per gallon per coat.
