Moisture Content of Wood When Applying TWP
Whether the wood you are staining is new or more aged, the moisture content is an important factor in the timing of stain application. Applying TWP or most any wood stain for that matter to a wood surface that is still holding too much moisture can result in many problematic issues. Trapping moisture in wood can promote the growth of mold and mildew. A moist and mildew infected environment can lead to wood decay and rot. This should be avoided at all costs. Wood rot will most likely progress to structural damage causing expensive repairs and replacements.
After the wood surface has been cleaned and prepped correctly prior to staining, it should be allowed to air dry for several days depending on the age, condition, and porosity of the wood. A good rule of thumb is to let the surface dry for several days before staining and do not stain if rain is expected. A deck that is mostly shaded may take a day or two longer to dry than a deck that sits in full sun all day. Weather and climate can also be a factor. Continue Reading
