This impregnation product is non-toxic, non-irritant and water based and uses microscopic (nano) fluoropolymer particles to permanently protect the surface from penetration by paints, oil and water and to allow it to “breath” naturally.
A nano particle is so small that it almost defies description and the incredible nanoscience ensures that every nanoparticle is gainfully employed and permanently bonded on the mineral surface.
One coat provides years of protection and, as a bonus, keeps stone clean and prevents moss growth; it also makes it very difficult to place posters or stick chewing gum
Drying time varies from 4 to 10 hours depending on the weather. Cost will vary depending on the surface to be treated, but typically an area of 100 square feet can be permanently protected for under £50.
