Protecting and restoring wood
� If the piece of furniture or beam has areas that are seriously deteriorated, i.e. they have lost their consistency, we recommend a previous step, sawing off that section or scraping it with an adze, for example.
�If you need to reinforce the piece, you can use joints or pegs.
� Remove the furniture from the place where it was, especially if this was an insect-infested spot. These are usually damp, dark and poorly ventilated.

Several solutions for the same product
� Clean the affected area with a stiff-bristle brush.
� Apply the anti-insect product. There are several formats. A paint brush will cover the whole surface.
� You can also inject it by drilling small holes in the wood, then cover them with plugs or wood cement.
� The traditional method is with an injecting needle. Inject the liquid into the holes left by the insects when they emerge from the wood.
� You can also use spray. There are spray devices with a thin tube that you can stick in the insect holes.
� Then there is the possibility of soaking the wood. For instance, place the legs of a table or chair in a bowl full of anti-insect liquid. The wood will absorb it.

Preventive treatment
� In both old and new wood it is a good idea to prevent attacks from insects that feed on wood.
� There are a variety of chemical products designed for this purpose. One efficient technique is to apply a deep varnish over the entire wooden surface. Most manufacturers of varnish offer a product like this.
� These normally flat, colorless products penetrate deep in the wood and are absorbed. They also protect against environmental factors such as fungi, mold and scum.
� It is applied with a brush or spray gun.
� You must repeat the operation after letting it dry as suggested by the manufacturer.

Tips
� When a piece is seriously damaged sometimes you have no choice but to replace it, be it a leg, beam or parquet floor. If the attacks is limited to one spot, you must eliminate it to keep it from spreading.
� If you cannot work in an isolated, well-ventilated place, you can do these procedures then seal the furniture or the damaged area of it. Keep it sealed the length of time recommended by the manufacturer.
