Wood Stain - Siding Stain

Siding Stain

Siding stain is one variety of wood stain with very high viscosity (others can be quite thin). Effectively, siding stains are paints that do not cover as well and do not form a hard film. They are designed to penetrate better and contain binders that are softer and more flexible, allowing them to last longer than harder, more brittle paints. Siding stain protects against solar radiation especially UV radiation, water, fungus including mildew, and insects. Different siding stains are distinguished by the appearance they impart to wood. Certain solvent-based or oil-based siding stains contain small amounts of paraffin wax, which cannot be painted over, although re-staining is still possible.
