Types of wood and available finishing for each product are listed on Metalco catalogues and in this web site.
A. Pigmented vegetable oil impregnation treatment
Attention: wood surfaces treated with oil naturally tend to turn grey in a variable period of time depending on the environmental characteristics of the place of installation of the product. The formation of the grey patina is a physiological reaction and is a self-protection of wood against weathering, while not affecting
the quality of the product. It is still possible to reduce the greying of the wood by making a regular renewal of the oiling process (see “Maintenance”).
CYCLE FOR OILING
B. Water- based paint
Attention: Metalco strongly recommends not to choose varnished wood when a regular maintenance is not possible (see “Maintenance”) and/or in case of severe atmospheric conditions (saline area, high pollution, steady sun and high temperature exposure, etc.). In such conditions, in fact, varnish coat will quickly deteriorate, causing a visible peeling.

On wood elements, Metalco offers warranty only against rot. In contrast, no warranty is provided on the duration of the treatments painting and oiling, although performed in a workmanlike manner, as influenced by numerous factors beyond the manufacturer’s control and may vary from environment to environment. For aesthetic and functional reasons Metalco requires regular maintenance of wooden surfaces (in conditions not particularly aggressive, at least annually). In the case of products which have undergone treatment or touch-up paint that require complete repainting, firstly sand to remove surface dust, dirt and any old paint. Secondly, proceed to the drafting of a good water-based paint for wood with brush or spray, as indicated on the product. The product must ultimately be left to dry (usually a time varying between 2 and 12 hours, depending on the amount and mode of application and climatic conditions). For products that have undergone treatment in oil and that need a touch up, simply proceed to lightly sand the surface to remove deposits of dirt, and then apply a new layer of oil. It is beneficial to proceed with the renewal of the oiling process when you notice that the layer of the previous treatment has lost consistency and is disappearing
(there is no standard but the timing depends on the conditions of “stress” in the environment where the product is placed). In case of any doubt about the proper maintenance procedure, please contact the Metalco Quality Department for advice.
In caso di dubbi sulla corretta procedura di manutenzione, è possibile rivolgersi all’Ufficio Qualità di Metalco per una consulenza.
