How Do You Polyurethane Driftwood

Protect the driftwood and its finish with two coats of polyurethane. Apply the polyurethane with a paint brush, using smooth strokes. Allow the first coat to dry for several hours before applying the second.

How do you seal and preserve driftwood?

Place the driftwood in a bucket to transport it home. If it is a bit buggy, soak it in water for several days and then let the wood dry out in the sun. Or place a smaller piece in a sealable plastic bag, spray a little insecticide in the bag — not directly on the wood — and seal the bag closed overnight.

How do you condition driftwood?

Mix a solution of one part bleach to nine parts water and fill a large container so that there is enough solution to completely submerge your driftwood. Place your driftwood in the solution. Soak your driftwood for 3 or 4 days, changing out the disinfecting solution each day.
