Nasier products are environmentally friendly detergents, suitable for removing some type of patinas from several cultural heritage materials.
Nasier products consist of stabilized enzymes with micro-nanotechnologic, inorganic and inert structures. The products differ in the type of patina to be removed and the substrate to treat.
Yes, it is only strictly necessary to blend them properly until the product becomes opal white and homogeneus throughout its volume.
Nasier products are to be considered safe for both operator and environment. There are therefor no special PPE for their use. However, it is recommended to use gloves or skin protective systems to avoid allergic reactions to the product (as reported in the Safety Data Sheet).
The products can be applied with ambient temperatures between 5°-38° C. Outside the indicated range, they may be subject to changes.
Depending on formulations, the pH varies from 6.5-7.5, 8.5 up to 9.
No, thanks to technology of which are made of Nasier products it is not necessary check the Ph of the substrate to treat.
Generally, all the Nasier formulations have a yield as 4 square meters per kg.
Yes, Nasier products are really developed in order to use the enzymatic cleaning also on extended surfaces.
It is not necessary to use products to prepare the surface. However, we recommend removing dust, or in the case the most voluminous mosses, from the area to be treated using brushes or water.
It is possible to apply them by brushes, spatulas or rollers in the case of larger and homogeneous surfaces. They can be applied directly or via interface (e.g. Japanese paper). It is not necessary to avoid contact with the metal parts of the brush.
Yes, they can be applied on wet surfaces and it is also preferable in the presence of high temperatures. In this case, we therefore recommend spraying the stone surface with water before application in order to maintain a certain humidity during the product's installation times.
It applies a layer of a couple of millimeters, enough to keep the application moist for the required processing times.
Yes, even if not strictly necessary for the application, it is still possible to apply a transparent film to prevent any dripping of the gel or which, in the presence of high temperatures, dries before the end of the shutter speed.
Application times vary from a few minutes up to approximately 90 minutes. They depend on the nature of the material, the nature and thickness of the patina, the environmental temperature in which the artifact is placed.
No, Nasier products are classified as cleansers, as a consequence do not have disinfectant function.
No, because the biocide might interfere the action of the product.
Yes, if a surface previously treated with a biocide product and adequately rinsed shows a regrowth of biological patina after a certain period, Nasier can be used to remove the new patina.
No, Nasier has not an effect on inorganic patinas.
No, Nasier has not an effect on pigmentation residues due to treatments with biocide products.
No, the products contain neither pigmenting substances nor components that produce pigments by reaction with biological patinas. Any pigmentation could be due to an incomplete and correct mechanical removal of the biological patina.
To remove the patina degraded by the action of the product, a mechanical action is required, the methods of which vary according to the nature and state of conservation of the product
No, Nasier are not toxic substances and the washing water after treatment can be allowed to flow into the surrounding environment without damaging flora and fauna
Yes, once the removal is complete, it is possible apply the product again, even if the area is still wet.
Correctly removed, Nasier products do not release any remains on the surface. Therefore are compatible with any other next treatment or product.
