Are Osmo products suitable for veneered wood?
Most timber manufacturers advise that oil or wax treatments are not suitable for their veneered doors but they rarely explain the reasoning.
Veneer is a thin slice of wood glued to the construction and following the absorption of an oil or wax treatment, there is a small risk of the glues delaminating from the veneer.
However, Osmo Door-Oil is a recommended finish for interior veneered doors, especially those from Howdens Joinery and LPD Doors – thanks to the combination of oils and waxes which build a high viscosity and quality product with a low solvent content, thus avoiding the risk of delamination.
Osmo finishes have been used for many decades on veneered surfaces without problems. Please always seek advice from the manufacturer and follow the instructions on the label and apply thinly. A trial application is always recommended.
For exterior veneered doors it is advisable to check with the manufacturer first, since Osmo UV-Protection Oil may be suitable if a clear/natural finish is desired.
Alternatively, Osmo Natural Oil Woodstain offers a selection of colours. As a guide, the darker the colour – the higher the UV-resistance. Please always test application prior to use. Please be extra cautious when using on glazed doors and always check with the manufacturer prior to use.
