Mabef easels are treated with raw linseed oil which represents the most natural method to protect the wood surface without drastically changing its natural features.  The wood is impregnated in its internal fibres emphasising all the sensations that only a natural material can give.

 To always keep its natural colour in the original wooden grains and to moisturise the wood, preserving it from cracking, we suggest to apply raw linseed oil with a soft cloth for the natural finishings.  For lacquered finishings we suggest to use products made with bee wax, to be applied with a soft cloth.

 As we are dealing with “live” materials, solid beech wood is subjected to shrinkage or expansion owing to changes in heat and/or in dampness which can cause a slight instability of the product or a light friction of the sliding parts.  To remove these inconveniences, it is suggested to tighten or to unloose the screws or the nuts according to the problem.
