Prepare the entire teak wood surface for staining by washing away all signs of soiling. If a smoother wood surface is desired, apply sander(s) in gradual degrees (higher to lower) of paper grit and carefully wipe away all sanding residue. In rare instances of resistant stain, employ a commercial grade teak cleaning product. Power rinse teak wood to be stained with clean water, and allow to air dry before applying stain.
Apply wood stain liberally with an uncontaminated brush to the entire surface. Wipe away excess stain periodically as it is slowly absorbed into the wood. The chosen stain will naturally dry and age to a lighter shade than it initially appears.
Wait until the teak wood surface is thoroughly dry (non-tacky) and smooth. Reapply another coat of stain if a darker shade is still preferred. Repeat Step 2.
Apply an approved teak wood sealant with an uncontaminated brush after the stain has dried; this will prolong the coloration's appearance. Apply liberally, and wipe away excess sealant as it absorbs. Allow to air dry.
