LASER

Cleaning involves the use of energy... see more

Cleaning involves the use of energy, which causes the organic and inorganic compounds of the pollution layer evaporate. This allows for their very safe removal.

Technology

Laser cleaning of monuments is the most effective and the safest of all of the methods used so far in the restoration of monuments. Often this is the only way to perform cleaning without harming the surface. Laser technology has been used in the treatment of all types of pollution of facades and architectural details, bridges, steel and aluminum structures, sculptures, textiles and paintings.

Technical specification:

Energy (mJ)335 (300)
Pulse duration time (ns)8/12
Average power (W)40 (36)
Frequency (Hz)120
Dimensions (cm)140x80x80
Weight (kg)350

Laser technology allows cleaning of plastics, ceramics, concrete, metal, wood, paper and fabric... see more

Safety of the cleaned surface

Laser method is a non-contact one, which does not have any mechanical or chemical impact on the cleaned surface. Mechanical cleaning causes irreversible loss in the historic substance and often causes going too deep through the pollution and patina layer. This method removes layer of cleaned surface, destroying relief, high relief, and traces of the sculptor's chisel. In case of chemical cleaning, strong acids not only remove unwanted buildup of pollution but they remove the minerals from the stone surface. In case of chemical cleaning it is not possible to determine precisely the depth of product penetration as well as stop the reaction in the event of failure.

The pollution from the surface can be cleaned in a surgical manner... see more

Owing to usage of visible laser, the pollution from the surface can be cleaned in a surgical manner generating the minimum loss of the material. By appropriate choice of power and wavelength, the laser gives full possibility of control over the thickness of the layer removed. This gives possibility to get rid of a particular stain from the surface, as well as a single buildup of pollution. This method, owing to elimination of dust and moisture allows maintenance of selective surfaces that are surrounded by other historical elements. This applies in the interiors of churches, palaces, museums.

We are able to perform the work twice faster... see more

Owing to the possession of two lasers, we are able to perform the work twice faster. Work efficiency of one laser can reach from 2 to 5 m2 per hour.

We are in possession of a car specially adapted for handling and transporting the laser. Working on high scaffolding and hard-to-access places is made possible by the use of optical fiber, the operation range of which can be up to several meters.

The laser technology, in contrast to the traditional one, does not use of water... see more

The laser technology, in contrast to the traditional one, does not use of water, caustic solvents, solutions, abrasives or other chemicals, hence after execution of works a minimum amount of waste is produced.
