Timberireland.ie aims to exceed your expectations in the supply of decorative and structural wood-based panels.
Valchromat is a panel made of wood fibres coloured in the production process. The fibres are impregnated with organic colouring agents and chemically bound to one another by a special resin which lends Valchromat unique physicochemical features, allows exploring the third dimension, the beauty of textures and the best of engineering.
Valchromat added value of comes not only from colour, but from the distinct composition.
Made in Portugal
Valchromat is produced in Portugal.
On the surface small wood fibres are visible, fibres which did not absorb the organic dyes. This peculiarity gives Valchromat its unique and natural look. Because wood, it’s main raw material, has natural variations in tonality, Valchromat can also show variations in colour.
Valchromat is classified as an MDF.HLS, it is a panel that can be used as a structural element to support loads in humid environments.
It has a higher density than a normal MDF, being more homogeneous throughout the thickness.
Greater resistance to flexion, elasticity modulus and internal cohesion, which allow its use in structural applications such as pavements supported by beams and structural walls.
Ease of Mechanizing / Milling
One of the mechanical characteristics that the panel has is the ease of being mechanized / milled without crumbling its interior.
Lower abrasion of tools
When cut, drilled or mechanized / milled it causes less tool wear.
When the panel is varnished or painted, the repulsion that arises after applying the finish is minimal.
A finish should be applied to the Valchromat panel to protect its surface and maintain its natural appearance. The finish may be varnish, wax or oil.
Given that there will be a difference in shades of the panels from the same batch, before installing them, the panels should be laid out side by side and ordered so as to minimise these differences in adjacent panels.
Before starting work, the panels must be placed side by side, organizing them to try to minimize these differences between adjoining panels.
Of the three kinds of finishes described, the varnishes are the most complex and at times the most difficult to choose given the broad range available on the market. Any wood varnish can be applied to Valchromat.
Two-component acrylic varnishes are widely used, as they do not yellow over time. The water-based varnishes change the natural colour of the panel less.
When a varnish finish is applied, the first coat applied is a primer. After the primer has dried, the panel should be sanded with fine sandpaper with grit size 320, to remove the granules that may result from peeling.
Next, a varnish finish is applied in one or two coats, in line with the manufacturer’s instructions. Between each layer the panel should be sanded using fine sandpaper with grit size 320.
Different varnishes have different appearances, from matt to gloss.
Primer and the varnish from the same manufacturer should be used to avoid incompatibility between them.
Wax or Oil Finish
The waxes or oils are usually applied with a single coat on the pre-prepared surfaces.
These kinds of finishes should not be applied on panels for installation in moist environments, such as kitchens and bathrooms.
