The feature for which this material is popping-up is because it is water-based, the primer that eventually suits the softwood exterior. The product allows you to work both on household and exterior wooden stuff hindering the mold & mildews.

Like any other work-process, the application of primer also has an initial preparation. The steps include cleaning the dust, chalk, rust, grease, & peeling paint from the targeted wooden piece.
