VIMASIL ACQUA is an excellent water repellent, solventless primer, based on a mixture of silane and siloxane, suitable for many absorbent mineral substrates, such as “monochouce” renders, bricks, sand-lime bricks, natural sandstone, and mineral renders. It has self-cleaning lotus leaf repellent effect to water, dirt, oil, grease, atmospheric pollutants and fumes. VIMASIL ACQUA reduces the capillary absorption of the building without clogging the pores or the capillaries. For this reason, there is no impairment of the building material’s breathability.
The product penetrates via capillary absorption consolidating and protecting it from cracking caused by penetration of rainwater and the disintegrating action of freeze-thaw cycles and other atmospheric agents, maintaining the vapour permeability of the treated surfaces and preventing saline efflorescence with a high water repellent action.
