Akemi Stain Repellent Nano Effect gives outstanding impregnation. It is formulated on high-quality, organic substances and is food safe as certified by a German testing institute. It gives a special impregnation which strongly repels water, grease and oil. It is used to protect flooring, table tops and working surfaces made of absorbent natural and artificial stone and can be used internally and externally. Akemi Stain Repellent Nano Effect protects the stone from staining spots and makes removing of any such spots much easier whilst the stone is left able to breathe. The protection begins to take effect after just a few minutes and is fully effective after 2-3 hours, whilst normally leaving the colour of the stone unchanged. Beginning of protective effect (20°C): 10 - 20 min. Consumption: approx. 1 - 15 m²/litre, depending on the absorbency and the composition of the stone.
