    Damage and repair of wooden items

    The most common damage to wooden items is permanent stains, wood decay, the presence of fungi, cracks and crevices, veneer damage or other structural losses, that need to be recreated.

    Caries

    Woodworms eagerly lay their eggs in the cracks and crevices of the wood. These beetles pose a great threat to any wood, for they feed on it and develop in its tissue. The effect of the bark beetle is round holes in the wood and the presence of sawdust.

    Stains

    When the discoloration breaks through the coating layer and reaches the inner structure of the wood, it is necessary to remove the outer layer of the object and to apply a remover in the form of oxygen acid to its surface. The next step is to touch up the discolored area with paint, and then varnishing.

    Mushrooms

    Mushrooms are one of the other dangerous enemies of wood, which attack the structure of the wood by breaking down its cellulose tissue (brown rot) or lignin (white rot) or both.

    Cracks and crevices

    Cracks and fissures are among the most common damage to wood, which is a material extremely susceptible to changing weather conditions. If the crack is slight, it will be easy to clean and stick them together, using a special vice. If the fissure is deep, it should be filled with pieces of wood and a suitable filler.

    Disinfectants

    On wood infested with insects (bark beetles or termites) a long-term preservative should be applied. Suitable preparations contain active ingredients, which destroy the larvae of pests. Apply the disinfecting agent after removing the wax layer, varnish or paint. It can be applied with a brush, spray on, immerse the object in the substance or inject it into the affected areas.

    Antifungal agents

    Antifungal agents help keep the wood from fungus or fight parasites, which have already attacked the wood tissue. First of all, wooden items should be protected against the effects of water and moisture, both factors favor the growth of insects and fungi.

    Klej PVA

    It is a new generation adhesive, also called white glue, which becomes transparent and shiny when dry. It dissolves in water; It is perfect for bonding any type of wood. It can also be used as a paint bonding agent, varnishes or other adhesives.

    Restoration of small cavities

    A small loss on the surface of a wooden object can be recreated, using wood putty. It is recommended to use a colorless paste and then paint it in the appropriate color. That the reconstructed fragment sticks well to the surface, it should be attached with wooden pins to the better-preserved part of the object.

    Putty for wood

    The consistency of the paste resembles putty. Available in stores. Also includes glue. Offered in several colors, which can be combined to obtain the desired shade.
    You can also buy a natural color paste and color it. Unlike wax, pastes absorb paint, but after painting they do not darken.

    Wax sticks

    Very practical. They are used to fill cavities and small cracks. Offered in many colors and shades. The sticks can be connected just like plasticine. Due to the greasy consistency, they are resistant to water absorption.

    Veneer replacement

    Surface, on which we intend to apply the veneer, it should be clean and smooth. Trim the veneer, leaving a half-centimeter margin on each edge. With a brush, we smear the wood surface with PVA glue and put a layer of veneer on it. Veneer by 30 press with two boards for minutes, and then wipe off the excess glue in accordance with the arrangement of the rings.

    Veneer

    These are thin sheets of wood, which are used as a better quality finish on wooden furniture. Ready-made veneers can be purchased in specialized stores (of the most popular types of wood).

    Loss of an important element

    In the event of destruction or fracture of an element, the necessary detail must be copied, then play it back. To do this, prepare a suitable piece of wood and cut out an element as close as possible to the original part.

    Wood

    For centuries, all types of wood available in a given era were used for the production of furniture and other equipment. Furniture and objects around us, which we intend to renovate, most often they are made of oak, pine trees, walnut, elm, maple, mahoniu, book, ash and larch.
