First and foremost, the average time from the application of a stain to the next application is 3-5 years on all products. Some stain companies may boast longer application times and less stain frequency, but any professional will tell you this rule of thumb is the safest to follow. The stain needs to be reapplied before weathering occurs so that the next coat is an even finish around the full exterior of your home. Catching this window and applying another layer or a topcoat is vital in not only saving money but preserving your logs. A maintenance program is vital to extend the time in-between stain cycles as well as identify weakening stain as soon as it is visible.
