I applied boracare on my old deck without surface finish about 4 years ago. I want to know how many years I will do it again.
Without treating the surface with a sealant, paint or stain after applying Boracare, the product will evaporate out the surface within a couple months. We would recommend doing a complete reapplication of your decking with Boracare and followed by a surface finish. It is important to seal your treatment of Boracare within 1 month with a sealant, paint, or stain to ensure the Boracare is locked into the wood. You will need to reapply the sealant or paint per the product label you choose.
