STONE CONDITION ASSESSMENT
In this phase two in situ essays are carried out to measure the current stone deterioration relating to the colour and hardness of the stone:
The product is applied through gun spraying twice a day. The period of the treatment application is 7 days depending on the deterioration condition of the stone and the environmental conditions. The product is applied by our experienced staff under the strictest conditions of safety and quality, in that way, we can optimise the product performance and the regeneration and consolidation of the stone.
In this phase, we proceed to bubble-wrapped the building in full, or, failing that, we just bubble–wrapped the area where the product is going to be applied with the aim of keeping the recommended humidity and temperature conditions in order to apply the product correctly. The material which is used for the bubble-wrapped is a latest generation plastic, made from plastic polymers which allow the implementation of jobs even under the most adverse climatic conditions.
TRACKING OF THE TREATMENT
When the application of the product is finished, it must be kept bubble-wrapped for, at least, 7 days with the aim of keeping the suitable humidity and temperature for the drying. With the tracking of the treatment we can prolong the effectiveness of the product.
LASER CLEANING TECHNOLOGY
The laser cleaning technology is the most accurate cleaning method to preserve our heritage. It is dry cleaning by using light pulses which remove the harmful deposits without using chemicals, abrasives, water or waste materials which can damage historic surfaces. Besides, laser cleaning is a procedure which guarantees excellent results without damaging the heritage and the microbial flora living inside the stone.
ASSESSMENT OF THE RESULTS
We carry out again the two essays which were conducted in the first phase of the regeneration process with the aim of assessing and demonstrating the effectiveness of the product once applied:
