Description

Prefinished Cladding in Siberian Larch Pine and Spruce

Primer coating is a very important process that ensures the long life of prefinished external cladding, the primer coat gives the cladding initial protection against weather conditions and also creates a suitable base for adhesion of the finishing top coat. Primer paint also contains agents that protect the cladding against mildew and blue stain after it has been installed, if the cladding needs to be chemically impregnated for durability this should be done before primer and top coats are applied.

If you don’t want to finish cladding boards with paint before they are installed, the boards should be at least primed, (although in order to avoid colour differences that may occur later in the area of board joints after drying, we recommend covering the boards with at least one layer of top coat before installation.

For the primer coating Puidukoda uses the water-borne alkyd primer paint Teknol 1881 manufactured by the company   Teknos      in Finland, which also contains additives to protect against mildew and blue stain. The structure of the alkyd oils used as binding agents in the primer paint is finer than that of acrylate used in acrylic primers so it penetrates deeper into the timber and gives better protection and adhesion with the top coat compared to common acrylic primer paints.

Teknol 1881 can be coated with 8 water-borne paints or oil-based paints.

For the primer coating our partners use an industrial automated coating machine Ceetec IP250  which coats all four sides of the boards with primer to ensure maximum protection of the boards against moisture and other weather conditions. The painting machine is equipped with high-speed rotating brushes, which apply an even paint layer on the boards and force the coating deep into the wood even on fine sawn surfaces. It is almost impossible to achieve this kind of quality finish with handheld tools, especially in site conditions.

Finishing with an Opaque Top Coat

The top coat is the final layer of prefinished external cladding, giving the cladding an aesthetically pleasing appearance and protecting the boards against solar radiation and rain, but remaining flexible enough to resist the expansion and contraction of timber when subject to fluctuations in relative humidity. There is no doubt that the best solution for this is acrylic paint, which, compared to oil based paints, is significantly easier to maintain and refinish, (the paint coating does not crack or peel  but becomes matt). During maintenance painting only loose particles need to be removed, then the cladding is washed and refinished). An opaque finish is also the most durable of all topcoats, (compared to transparent finishes it has significantly better solar radiation resistance properties). A finished layer of the correct thickness is very important to ensure the maximum lifetime of the cladding which is virtually impossible to achieve using hand held tools in site conditions. If the top coat is applied too thickly the result will be that the paint will dry unevenly and proper adhesion to the board will not be achieved, resulting in surface cracks which will later mean the paint layer will  peel off. The best and most durable result is achieved by applying the paint on the surface in several thin layers ensuring that the layers have the correct thickness. The chosen colour shade is also of critical importance – the more pastel (bright shades will fade quickly) and lighter (dark colour shades absorb more solar radiation and thus volume fluctuations in the paint and cladding are more extreme) the colour is, the longer it will last.

For painting Puidukoda uses the Nordica EKO water based semi matt acrylic top coat, manufactured by   Teknos     in Finland, which can be tinted with  opaque colours. The top coat is applied to the surface of the timber on a paint line with high pressure spray equipment which guarantees that the paint layer is even, smooth and of the required thickness, ensuring the durability of the surface coating.

The paint layer thickness for a smooth board is approx. 0.12 mm and for a fine sawn or brushed board is approx. 0.13-0.15 mm.

The Teknos painting system has, in addition to a primer coat, 2 layers of top coat. and we offer cladding  with a final finish consisting of two top coats. If necessary we can also offer with a single top coat which should be finished with a second top coat after the cladding has been installed.

Painting with Translucent Top Coat

A translucent top coat is a semi transparent wood finish achieved by combining pigment with a clear base. Pigment is also what gives the coating its protection from UV Light – no pigment equals no protection. Because this coating is semi-transparent it doesn’t contain any pigment in the base, (and therefore less dry material), its resistance to UV light is diminished and durability is less than that of a board with an opaque top coat. We recommend using an opaque top coat of a light pastel shade on fine-sawn boards for maximum durability with minimum maintenance, depending on the house location and architecture this combination may last 15  years or more without additional maintenance.

Please remember that translucent paints may have to be refinished every 3-7 years (depending on the type of timber used, colour and;the buildings location and architecture).

For translucent coating Puidukoda uses semi matt Nordica EKO or matt wood preservative Aqua Primer manufactured by    Teknos    in Finland, which can be tinted with different translucent colours. The Teknos painting system has, in addition to a primer coat, 2 layers of top coat. and we offer cladding with a final finish consisting of two top coats. If necessary we can also offer with a single top coat which should be finished with a second top coat after the cladding has been installed.
