Osmo Exterior End Grain Sealing Wax

Please note: Osmo End Grain Sealing Wax cannot be shipped to the greater Los Angeles area due to restrictions.

Osmo End Grain Sealing Wax is perfect for all exterior wood projects where the end grain requires protection from weathering and water ingress. Ideally suited for use as a decking end grain sealer, this product is compatible with other products in the Osmo exterior wood finishes range. The surface is water and dirt-resistant. Swelling and shrinking as well as 'bleeding' of the contents of the wood will be reduced. It is clear and is therefore universally applicable.



Timber end grain should be clean, dry and free from surface contaminates that may form a barrier or seal.




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
