Why lining darkens
Blackening of the cladding board is quite common, especially in the case of construction work on its own. In this case, the technology of wood processing is usually violated, leading to damage to the material by mold and fungus. As a result, the presentation of the tree becomes worse: it turns black, saturated with moisture, warps.
Most often, the reason for the color change of the lining is the adverse environmental impact. In addition, the tree darkens as a result of improper maintenance or its low quality characteristics. For this reason, when balcony decoration or summer cottages, many are trying to replace harmless and environmentally friendly material with toxic fire-hazardous plastic.
A feature of any tree is the gradual loss of freshness and attractive appearance. This does not depend on the means by which the wood was treated before facing.
You can use different types of lining:
- cedar shalevyka is very sensitive to sudden temperature changes and the effects of water;
- linden material is more stable, but also darkens over time;
- pine and larch respond equally to weather conditions.
A competent approach to solving the problem guarantees the strength and reliability of the wood paneling.

What to do when darkening the lining
There is no need to disassemble the wood panels that have lost their natural appearance and install new ones. Craftsmen came up with many ways wood lightening. They use:
- oxalic acid;
- hydrogen peroxide;
- bleach.
There are special ways and means to correct the situation and preserve the natural structure of the tree. To this end:
- treating the surface with a brightening composition;
- coat it with lighter tone;
- sanding;
- paint.
Whitening products:
- Do not spoil the structure of the tree;
- non toxic
- harmless;
- refractory;
- give the material wear resistance.
All these methods of whitening have not only advantages, but also disadvantages. When using clarifying compositions based on active substances (chlorine, hydrochloric acid), in order to maintain their effect, lining on top is covered with a protective varnish light color.
The greatest effect is achieved if the product is applied in several layers. In this case, it will not be possible to achieve the initial appearance, but the exterior will significantly improve.Coloring allows you to completely change the appearance of the surface, but the effect of the wood structure disappears.
The method of processing with sandpaper and further coating with acrylic makes it possible to restore the lining to its former beauty, to increase its resistance to weather changes. When processing the front surface, do not forget about the back side.

Preparation for painting
Before coating the lining with varnish or acrylic, it should be cleaned of dirt and degreased with an alkali-based solution, and then sanded with a flat pumice or grinding wheel. This will require tools:
- sponge and brush to remove contamination from the surface;
- roller, brush or spray for applying reducing and clarifying substances.
This operation leads to the loss of all protective characteristics of wood. To restore them, treatment with a disinfectant is necessary. He will not only be able to protect the tree, but also improve the quality of the varnish coating.

The use of conventional oil paint to renew the surface gives it an artificial shine and hides the natural pattern of the tree. In addition, such coverage is short-lived and will soon require modernization. When using acrylic varnish for wood panels:
- the original pattern is preserved;
- provides attractive appearance;
- resistant protection against moisture and weather changes is created;
- lining service life is extended (up to 8-10 years).
Depending on the degree of darkening, you can use the concentration of the solution in the finished form or dilute it with water in a ratio of 1: 1. To avoid differences in the tone of the coating, it is necessary to apply a test smear in an inconspicuous place. After that, the coloring of the paint is selected.
The recovery procedure consists of step-by-step operations:
- surface cleaning;
- drying wood;
- antiseptic treatment;
- sample and shade;
- applying acrylic paint.
Final lining finishing is often used in the repair of balconies and summer cottages. In order for the casing to maintain a beautiful natural look for a long time, it is necessary to observe the rules for the operation of wood material and to know how to lighten it. For a good restoration of darkened panels, choose the right bleaching method. For this purpose, it is advisable to consult with specialists or familiarize yourself with the instructions.
