How to Add Linseed Tung Oil for Paint & Stain on a Redwood Deck

Linseed and tung oils soak into the pores of redwood, providing a protective coat and adding sheen to a deck's surface. When used with stain, each oil seals the stain into the redwood and keeps moisture out. When used with paint, the oils prevent moisture from seeping through the paint into the redwood. Stain and paint shouldn't be used together, but either can be used in conjunction with linseed or tung oil.

Instructions

  1. Stain

    • 1

      Sweep all debris off the redwood deck. Spray the deck clean with a garden hose or power washer. Allow the deck to dry thoroughly.

    • 2

      Scrub the surface of the redwood deck with #0000 steel wool pad soaked with denatured alcohol or paint remover wash. Allow the redwood deck to dry thoroughly.

    • 3

      Pour stain into a paint pan. Make sure the stain description states the product has a mold-resistant chemical in it. Although resistant to moisture, linseed is especially inviting to mold. Dip a long-handed paint roller into the pan to cover the roller with stain. Apply stain to the redwood deck. Work in 4-foot sections. Allow the stain to dry thoroughly.

    • 4

      Apply the tung or linseed oil to the dried, stained deck with a paintbrush or clean cloth. Apply additional oil to areas that look dry and wipe away any excess oil with a cloth. Allow the oil to sit for 15 to 20 minutes.

    • 5

      Smooth rough patches on the deck with a #0000 steel wool pad.
