Method of coating concrete floors with photocurable coatings

摘要

A method of coating a concrete floor is disclosed in which the concrete surface is coated with a homogeneous liquid coating composition containing maleate or fumarate unsaturation in combination with vinyl ether unsaturation and a ketonic photoinitiator, the wet coating is allowed to seep into the concrete surface and to flow out on the concrete surface to form a smooth coating, and this coating is cured by exposing it at light having a wavelength in the range of from about 200 to about 600 nanometers.
