Maintenance

Stain and seal a wood fence

A fence finish needs preparation that matches the wood and existing coating. Use the chosen product’s instructions to plan cleaning, drying, application, and future care.

What you'll learn

  • How to identify the existing finish before choosing a new product
  • Why preparation and moisture requirements come from the product instructions
  • What to check on a small inconspicuous test area
  • Which access and surface conditions to discuss with a staining contractor

Project checklist

  1. Identify the wood and existing coating, and read the new finish’s compatibility and preparation instructions.
  2. Check for damaged boards or loose connections before surface preparation. Have structural problems assessed first.
  3. Choose a cleaner and application method allowed by the product instructions; protect adjacent plants and surfaces.
  4. Check the product’s wood-moisture and weather requirements instead of assuming a fixed drying period.
  5. Test the finish in an inconspicuous area and follow the labeled application, cleanup, and disposal instructions.
Safety note

Do not assume paint or stain can go over any existing finish. Ask the manufacturer or a qualified contractor about compatibility before coating the whole fence.
