Product Description

Osmo End Grain Sealing Wax protects the end grain from cracks during all elements of weathering. Minimises the water absorption, as well as the seasoning of the end grains.

Osmo End Grain Sealing Wax makes the surface water and dirt resistant. Swelling and shrinking as well as 'bleeding' of the contents of the wood will be reduced. Osmo End Grain Sealing Wax also protects from the inside as it is absorbed into wood capillaries. Swelling and shrinkage as well as the leakage of wood extractives are reduced. It is clear and thus can be used universally.

Wood surface must be clean, dry and frost-free (moisture content max. 20%). Osmo End Grain Sealing Wax is ready to use, please do not thin. Stir well before use.
The finished surface is, among other things, influenced by the wood‘s natural characteristics. Therefore, a trial application is always required, especially for unfamiliar
surfaces. Apply generously to end grains with Osmo Natural Bristle Brush. To achieve optimal protection for strongly absorbing end grains, we recommend applying the sealing wax two times wet-in-wet or after drying carry out a second coat.
