For the Consolidation of Porous Stones


CONSOLIDATED DRY is a hygro-hardening (i.e. it polymerizes due to the reaction with moisture contained in the air), one component product based on partially hydrolyzed Polyethyl Silicates. The product is flammable.

Usage field

CONSOLID DRY once applied in several coats, wet on wet, on a natural stone artefact, penetrates deep into the capillaries where it reacts and turns into a silica gel. At the end of the reaction it becomes the new binder.

CONSOLID DRY is used as an impregnating agent for all sorts of building materials with high absorbing capacity: in particular it was specifically designed to protect heritage buildings against decay caused by weather agents.

CONSOLID DRY is ideally suited for the consolidation of medium-high porous materials.


CONSOLID DRY is available in 1 and 5 liter containers.


For the Consolidation of Porous Stones

  • The following rules must be kept into consideration in order to carry out a proper intervention:
  • the surface cleaning shall be undertaken with the gentlest means possible (using DESMOG A or other methods);
  • if the material is in an advanced stage of degradation and the surface very crumbly, a coat of CONSOLID DRY shall be applied at least 2-3 days before starting the washing;
  • apply the product only to dry and absorbing surfaces;
  • for at least 2 days after application, the treated material shall not be exposed to sun or rain;
  • the product shall be applied at temperatures above 25°C and at low humidity (RH = 50% max);

The product shall be applied by low pressure sprinkling, with a brush or a roller, by immersion or tamponing.
The correct method of application involves the penetration of CONSOLID DRY into the healthy stone structure.
To this end it is necessary to carry out a few patch tests to avoid the formation of a superficial crust that might cause, in the long term, an even worse damage than the one at hand.
To obtain a deep penetration it is necessary to apply several coats of CONSOLID DRY wet on wet.
CONSOLID DRY is ready to use. There is no need to dilute it with anhydrous white spirit unless strictly required i.e. when the porosity of the layer to be consolidated is extremely low.
Wait two weeks after the first treatment to allow time for the initial active substance to cure.
Then, if deemed necessary, a second impregnating cycle can be carried out.
Should a colour change toward gray or the formation of shiny layers on the surface occur during the application, it would show the presence of excess material that must be removed immediately with an appropriate solvent.
Check in advance one or more small areas (0.5 m2) to detect any unforeseen incompatibilities: high concentrations of ions can generate white efflorescence.

Average Consumption

It is very difficult to quantify the coverage of CONSOLID DRY, because it varies on a case by case basis, however, the average amount needed is 0.4 liters/m2 up to 10 liters/m2.

It is recommended to determine the exact coverage rate on a surface sample before placing a purchase order.
