The sandblasting equipment is then turned on, with its help the powerful sandy composition under high pressure is supplied. Grinding at the same time is contactless. This processing must be fully over the entire design so that in the end there were no darker ugly areas.

The design treated in this way is completely cleaned by the resulting wood dust and sandstone residues. Must apply high-quality primer. It should be applied to the foundation of a wooden cut immediately after this cleaning.

After that, protective formulations and varnishes are applied to the treated tree. It should also be covered with its antiseptic substances, to give a more decorative type, the design can be painted.

  • High quality level. Processing using sandblasting equipment allows you to achieve an ideal smooth surface, it will not even be small defects.

  • Allows processing in any places. This method will be the best option in cases where it is necessary to process hard-to-reach places, including angular connections, joints.

  • Allows you to give a greater density. In the process of such treatment, the material is consolidated significantly, because the sandblasting unit removes the soft upper layers of the breed. It provides better absorption of various protective impregnations, which extends the service life of wooden products.

  • Ability to process darkened damaged areas. Sandblasting machine allows you to remove rotten dark places on wood without prior whitening.

  • Allows you to make a brightest painting. If you paint the sawn timber after such treatment, then the design will be much more saturated, it will be able to hold longer.

  • The possibility of deep-winning. In this case, wood will acquire a beautiful relief, while the pronounced natural structure of the tree will be visible. Such a technology will give the material more expensive designer appearance.

  • Will be able to come in almost any types of wood. Treatment with a sandblasting unit can be carried out on the surface not only standard bars and boards, the method is also suitable for glued, rounded, profiled material, for imitation of a bar.
