Bora-Care is a very safe product and it is considered a green product as well. Typically, it takes about an hour for the surface of the wood to dry. After application has dried completely, it should be perfectly fine for children and pets to re-enter the house.
Just so you know, Bora-Care will not kill, treat, or prevent mold growth. It only works for fungus or wood destroying insects, not mold. Only Bora-Care with Mold Care will treat and kill and prevent mold. Bora-Care will take at least 30 days usually to diffuse through the entire piece of wood. This of course depends on the thickness and moisture content of the wood. The outer layer though usually dries within 24 hours or at least is OK after 24 hours to treat again or apply a stain or sealant to the wood.
