Water repellent and anti-efflorescence alkylsilane solution for masonry

Code: CSX.0159

Components: 1

Appearance: Liquid

Silane-based water-repellent emulsion, penetrates the capillary pores of mineral substrates and reacts with the hydroxyl groups on the surface forming an invisible water-repellent barrier that does not allow water to penetrate but which leaves the breathability to water vapor unaltered. Specific for preliminary treatments against the saline efflorescence of masonry bodies, in green building interventions and in the restoration of period and monumental buildings.

SANAREG is an alkylsilane water emulsion, non-hazardous, non-toxic and VOC-free. The application of SANAREG does not alter the original wall breathability.

Particularly indicated in combination with the cycle of natural dehumidifying plasters UNTERSANA, SANATIGH and SANASTOF. This also applies to UNTERSANA, CALEOSANA and SANASTOF.


From 0.10 to 0.20 kg of SANAREG for each square metre of surface to be treated, based on the porosity of the support.

Use fields

Inhibition of saline efflorescence in dehumidifying remediation with the application of renovating macroporous plasters.

Preparation of supports

Remove the soilings and saline manifestations by vigorous brushing; then eliminate any dust residue. Surfaces should be as dry as possible at the time of application.

Use method

Apply SANAREG by nebulisation, proceeding from top to bottom: it can also be applied with a long bristle brush. After a few hours remove surface excesses. In the case of the subsequent application of plasters, paints, etc., preliminarily and carefully rinse the treated surfaces.
Not to be used for surfaces intended to remain "exposed" except in case of preliminary verification of application results.
SANAREG is a moderately caustic solution at the implementation stage: do not ingest, wear protective gloves, goggles and clothing, take the necessary precautions.
SANAREG has an aqueous base, for this reason, its effectiveness is not compromised even if the support is not perfectly dry at the time of application.
