How to use

Suitable surfaces Softwood (pine, larch, spruce etc.) and various hard woods. Drying time may increase and colour may change in cases of dense woods such as oak, chestnut or tropical woods. Try wood stain on a sample area first.
Surface requirements The surface must be dry and free of dust and grease.
Application Evenly apply thin layer with lint free cloth or single-disc application machine in cases of large surfaces. Only use if temperature is above 10°C.
Thinner The bio pin Weather Protection Stain comes ready for use. If necessary dilute with water.
Preparation For tropical wood or oak try wood stain on hidden area first. Cut or burn out resin ducts. For ecological and health reasons bio pin Weather Protection Stain does not contain any biocides. For construction wood (eg timber frame) reliable protection against wood-destroying fungus and insects and limited protection against blue-stain can be achieved with bio pin Boric Salt. For unlimited protection against fungus and blue stain please apply conventional blue-stain protection primer.
