Problem Solver - Moisture

Problem

Timber to be coated should have a moisture content close to what it will be in service. Below 14% for interior timber and between 15-18% for exterior timber is recommended, and 5% maximum in most masonry. You can obtain a moisture meter to check the content of a surface. Certain finishes do have moisture permeability allowing moisture to escape.
