How to Restain & Seal Wooden Swing Sets

Wooden swing sets cause some concern in preserving the wood from harsh weather. By staining the wood and then adding coats of polyurethane to the wood, you can prevent any water damage that nature may try to inflict. Within two days time, you can spruce up the appearance of the swing set and protect the wood from any damage.

Stain and seal a wooden swing set to preserve the wood against the weather.
  1. Sand the wooden surface of the swing set using the 120-grit sandpaper. This will remove any roughness on the surface and smooth away jagged edges.

  2. Sand the surface of the swing set using 220-grit sandpaper. Work into any crevices to create a smooth, stainable surface.

  3. Remove dust from the surface using a damp towel. Wipe the entire surface and allow wood to dry completely before continuing.

  4. Put on rubber gloves and dip stain cloth into the wood stain. Apply stain in a circular motion until every wood surface is covered. Allow stain to set for five to 15 minutes.

  5. Wipe away excess stain using old rags. Do not leave any puddles on the surface as this can create dark spots on the surface. Allow stain to set for four to six hours.

  6. Repeat Steps 4 and 5 if you desire a darker finish.

  7. Apply a thin layer of polyurethane to the entire wood surface using a 4-inch foam brush. Apply polyurethane in long strokes to cover the entire surface. Allow polyurethane to set for six hours and apply a second coat if necessary.
