Urethane Cement is now the leading technology for durable industrial and food production floor toppings.
Older screeds like Sureshield and epoxy mortar screeds did offer strong floors, but there are essentially bags of dry sand stuck together with resin, leaving millions of voids between the particles.
UC Floor is different. It is a high performance, resin rich mix of resin, cement and fillers. It is a homogenous mixture that is devoid of voids.
So beyond being very strong, semi-flexible and offering high chemical resistance, it can in no way harbour bacteria.
