This stage’s aim is to get rid of the worm-eaten parts and to see the sound wood.

It has to be done with a manual scraper. For painted woods, you have to scrape with an abrasive disk.
Without doing this stage, sprayed products would stay on the wood’s exterior surface and not penetrate it.

Brush and drill

Then the scraped parts have to be cleaned with a metallic brush to eliminate the dust.
Drill 3 to 5 holes per meter with a Wood Auger bit, in a horizontal line or in staggered
rows depending on the wood section. 2/3 of the beam thickness is the depth to respect.
For very large sections of wood (> 20/20 cm), the holes are made on two opposite sides of the wood pieces.


The aim is to create, inside frame parts, insecticide active zones to eliminate larvae and insects which cannot be reached by a surface treatment.

• Drive in the plastic injectors with a hammer.
• Inject the treatment product between 5 and 15 BAR until saturation by using a
gun and an injection nozzle combined with a MABI pump.
