Osmo Polyx-Oil Effect Raw 3044 is a lightly white pigmented finish suited for light coloured wood species – in particular, Oak.
Application of Raw 3044
For example, when the wood is untreated or after the surface has been sanded, it is important to apply thinly and spread well, along the grain. The white pigments must penetrate the surface to ensure an almost invisible effect is achieved.
White Pigment Remains Visible
If the white pigments remain visible on the surface, this is a result of the oil not penetrating the surface properly.
This can happen due to a number of reasons including:
- Over application
- A lack of removing the excess
- Poor application method e.g. application against the grain
Raw 3044 on Darker Wood Species
Darker coloured or ingredient-rich wood species may also highlight the white pigment. Carrying out a trial application beforehand is required, especially for unfamiliar surfaces.
As a solution, you can try lightly sanding the excess white pigment back once the surface is dry. We recommend using a sanding mesh type abrasive of P180 grit. This is because a mesh will not clog as easily as sandpaper.
The sanding process should be carefully carried out by hand using a sanding block behind the sanding mesh and working along the grain of the timber.
Ideally work on full, yet isolated boards working up to the edges of the boards accordingly. Only use light sanding pressure that is enough to cut away the excess pigment and avoid cutting into the wood.
You can practice this technique beforehand if you have any areas/boards in an inconspicuous area.
Once cut back, carefully remove the dust with a soft dry brush and vacuum cleaner. Please avoid anything wet!
Once prepared, apply Raw 3044 more thinly with a brush.
Please apply along the grain and stretch out well. If white is visible, stretch out further or remove excess product with a lint-free cloth before it dries.
Also, we recommend you avoid applying a clear oil over partially sanded areas as this will tend to darken the wood surface.
