Where it is not possible and/or advisable to leave the wood with no finish, Metalco is able to provide its wood oiling with vegetable-based or water-based paint. Metalco price lists indicate the types of wood and finishes available for each product.
A. Impregnation of vegetable oil:
It is the best treatment for exotic hard woods, such as Pauoro, Iroko, Teak or similar.
This treatment is not recommended in case of softer woods (eg Okoume).
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
This finish is excluded on most types of hardwood such as Pauoro, Teak, Iroko or similar and on Accoya® or wood treated Thermowood®.
Attention: Metalco also strongly advises against the choice of a varnished wood where it is not possible to carry out regular maintenance (see “MAINTENANCE”) and/or in case of placement in particularly harsh weather conditions (saline area, strong pollution, constant exposure to strong sunlight and high temperatures, etc…).
In such conditions, in fact, the layer of paint is intended to degrade quickly, presenting a noticeable flaking.
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.
