In one bottle you can look at Alpa Polyfluid, for example. It protects against moisture, mold and mildew. For waterproofing of facades Polyfluid is recommended by injection: under high pressure waterproofing composition is injected into the material for 2/3 of the wall. On contact with water Polyfluid crystallizes and forms an impermeable barrier, impervious to rising water. Thus a waterproofing belt is formed along the entire wall. The effect is achieved after 4 hours and lasts for up to 8-10 years.

You can also consider a cheaper option, such as a hydrostop. Impregnation forms a hydrophobic coating, reliably blocks the penetration of moisture through the pores and capillaries, penetrates deep into the surface structure of the stone (up to 5 mm).Intensifies the hydrophobic properties of concrete and cement building mixtures
