As many of our exterior treatments are applied as a fine mist, it only takes about 20 minutes for the product to dry. Once the product is dry, it is set up and ready to withstand the normal weather patterns for the days, weeks, and months to come.  Our technicians will keep an eye on the radar, and make a decision as to whether or not the product will have adequate time to dry.  This is a common concern, but remember, as a valued customer, we provide you peace of mind in knowing you will have a re-treatment warranty in place if need be.
