How To Apply Osmo End Grain Sealing Wax

Always do a small test area before starting any project to assess compatibility and end result. Follow the manufacturer’s instructions on the tin at all times.

  1. Apply End Grain Sealing Wax generously to end grains with an Osmo Soft Tip Brush
  2. For optimal protection for strongly absorbing end grains, apply the sealing wax two times wet-in-wet or, after drying, carry out a second coat
  3. Wipe away any excess wax from other areas with a clean, lint-free cloth

For routine maintenance, simply re-apply Osmo End Grain Sealing Wax to exposed end grain as and when required
