Special end grain sealer – protects against cracks resulting from weathering!
Clear wood coating developed especially for sealing end grains in order to protect these against cracks resulting from weathering. Osmo End Grain Sealing Wax minimises water absorption as well as drying-out at end grains. 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.
Osmo End Grain Sealing Wax is especially suited for the end grains of decking made of hard and softwoods, such as Bangkirai, Teak, Massaranduba, Garapa, Cumaru as well as Pine, Spruce, Douglas Fir, Larch, Cedar, Thermowood etc.

NUMBER OF COATS
Two coats on an untreated substrate; for renovations, normally one coat on the clean surface is sufficient.

Wood surface must be clean, dry and frost-free (moisture content max. 20%). Osmo End Grain Sealing Wax is ready to use. Do not thin. Stir well.
The finished surface and the product coverage are influenced by several factors, including the condition of the wood. Therefore, a trial application is always required, especially for unfamiliar surfaces.
With Osmo Flat Brush, apply generously to end grains. To achieve an 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.
With Osmo Brush Cleaner (free of aromatic compounds).
Approx. 3-4 hours (normal climatic conditions, 20-23°C/ 50-65% rel. humidity). Ventilate well while drying. Lower temperatures and/or higher air humidity may increase drying times.
Osmo End Grain Sealing Wax is clear and therefore it can be applied universally. Please only apply to end grains. Not for area treatment. Wipe away any excess wax from other surfaces with a cloth. Oils enhance the natural tone of wood (permanent wet effect). After drying, we recommend coating the other wood surfaces with Osmo wood finishes (e.g. Bangkirai-Oil, Massaranduba-Oil, Country Colour or Natural Oil Woodstain).
