Colour stain & Colour glaze
Water-based colour stain
The term “staining” is used in wood processing to describe a certain surface treatment. The aim is to change the colour tone of the wood. In doing so, the stain accentuates or evens out the natural grain of the wood. Generally, a distinction is made between chemical staining and physical dye staining. ZEITRAUM uses a so-called “HYBRID dye stain”. With these stains, colour pigments are dissolved in water. During the application of these coating systems, the colour pigments first penetrate the “pores” of the wood with the water. The water then evaporates. The pigments, however, remain in the pores. The wood appears in a different shade. By introducing the colour pigments with the help of water, a “deep colouring” is achieved. The lighter “early wood” absorbs more colour than the “late wood” due to its coarser microstructure. Thus, the wood appears as a coloured negative. This type of surface treatment is very durable and there is no danger of flaking paint.
The stain used by ZEITRAUM contains only about 1 % VOCs (Volatile Organic Compounds). The formula is free of wood preservatives, toxic heavy metals and formaldehydes, phthalate softeners, CMR substances and volatile halogen-organic compounds. The only “disadvantage”: it must be varnished afterwards.
The colour glaze differs significantly in appearance and technique from our colour stains. It remains on the surface, so it does not soak that much into the pores of the wood. As a result, it is less transparent and a well covering colouring is achieved. The character of the wood and its structure is visually and haptically preserved and an elegant pore pattern is created. In this way, a colour glaze clearly differs from an opaque colour varnish, although the glaze must subsequently be coated with a clear varnish.
