CEMTEC CONGUARD XTRA is a siloxane based penetrating sealer designed specifically for the
treatment of masonry materials and concrete surface. CEMTEC CONGUARD XTRA protects concrete and masonry surfaces from the effects of exterior exposure and weathering. CEMTEC CONGUARD XTRA penetrates deep into the surface pores and reacts chemically to provide a durable, long lasting barrier against water and salt intrusion. This can substantially reduce the damaging effects of acid rain, efflorescence and dust/dirt degradation.
