Reinforced stone strengthener PELICOAT PRO ROC+


PELICOAT PROROC+ is a professional reinforced impregnating agent for restoring deteriorated stones.

The major advantages of the ethyl silicates are their good penetrating power as well as the fact that pores never become clogged which maintains the breathing space of materials.



– Ready to use product. Do not dilute.
– Generally the product is applied by spraying. It is also possible to treat movable parts by immersing them in a bath.
– A brush or low pressure sprayer can be used. Make sure the amount of product applied is absorbed by the stone’s capillary system.
– Avoid applying an excess amount of product which may run off and will immediately be absorbed by untreated parts.
– The materials treated must be dry. The moisture contained in the materials will make the product react.
– Several wet-on-wet treatments are generally needed,and are to be applied at intervals of 20 to 30 minutes.
– To determine the appropriate amount of product to be spread, we advise you to carry out preliminary tests, or to approach a specialized control laboratory.

– Always carry out preliminary tests on a small hidden surface before treating any part.
– The total time needed for the strengthener to deposit silica gel varies from one to three weeks. at most
– Renew operation if necessary 3 weeks after the previous treatment.
– Usual consumption is between 0.5 and 3 L /m² depending on the porosity of the material.


For a preventive application, we advise you to use a less concentrated mixture PRO ROC.
