Whatnot – Removal of wood decay and reconstruction of wood losses. Furniture attacked by bark beetles or mechanically damaged is seemingly unusable. However, it is worth repairing damaged equipment and restoring its functionality and former nobility. It requires a lot of commitment, but the reward for the effort will be the end result.
Wood, which we will use to recreate the damaged elements, it should be similar to the species of wood, the furniture is made of. As a last resort, it can be replaced with another type of material with a similar grain pattern, and then paint over the fitted piece.

• Syringe and needle

• Wood fixer
• Beech wooden slats
• Mahogany wood slats
• Walnut-colored wooden slats
• Klej PVA
• Mahogany-colored varnish
• Steel wool with granulation 0000
• Walnut colored beeswax
• Cotton cloth
Before the renovation, this beautiful shelf was attacked by decay of wood. The elements of the furniture, weakened by the decomposition process, broke. Everything was covered with dirt and numerous stains.
1 First, with sandpaper, carefully remove the layer of dirt and old varnish. In this way, we will prepare the foundation for subsequent treatments.
2 After deleting layers; dirt, which could reduce the effect of the insecticide, impregnate the surface and inject the insecticide into the bark beetle holes; several times, at an interval of fifteen days.
When the insecticide dries, in the same way, we inject the hardener into the wood, made of acrylic resins (Paraloid-B 72, dissolved in a 10% xylene solution). Then cover the secured holes with wax of the appropriate color.
3 From beech wood, trim the skirting missing in the side finish of the piece of furniture. Grind the finished element with sandpaper, until we have a completely smooth surface.
4 To recreate the rotten legs of the shelf, you need to use two glued mahogany strips (individual slats do not match the thickness of the legs). The slats should be cut evenly and carefully fitted, so that the gluing is not visible. Lubricate the surface of the slats with glue, Put both elements together and press them with a vice. In order not to damage the wood, put pieces of plywood between the bar and the vice jaws, which will protect the wood against scratches.
5 In order to reconstruct the beech frame supporting the shelf, we form a pin that connects the frame with the shelf's leg, by appropriately trimming the element shown in drawing no 5. A kind of wooden protrusion is created, which will fit into the hole already existing in the leg.
6 A hole must be made in the new leg of the shelf to connect to the shelf frame. Marking the exact location and size of the hole, we clamp the leg in a vice and use a suitable chisel to enlarge the hole to the correct size.
7 To connect two parts of the wood, we cut out unnecessary fragments, matching the elements to each other. We shape the finished parts with a file or sandpaper, all the time checking, whether they fit well together. The precision of execution is extremely important, otherwise the join will be visible.
We paint the new parts with walnut-colored alcohol paint. Apply one diluted layer of paint to the pieces of walnut wood, while the beech-colored parts are covered with three layers.
8 The moment has come, to connect the new parts to the original piece of furniture. Cover the joined surfaces with glue and press the whole thing down with a vice. After the glue dries, we cover the visible joint with wax in the appropriate color.
9 So that the surface of the wood is uniform, it should be protected with three layers of mahogany varnish. Finally, all elements are polished with steel wool of granulation 0000 and cover with beeswax, then gloss with a cotton cloth.
