Abstract: A multiple layered waterproofing coating comprising a first, flexible layer having relatively high flexibility, adhesiveness and elongation properties, which is adapted to bridge cracks even in low temperatures, and a second, protective hard layer having high tensile strength and low adhesiveness properties. The layers are prepared from liquid formulations which are spray applied to the surface to be coated, primarily in below-grade foundations. The first, flexible layer is formed by spraying onto a surface a liquid formulation which provides a dried coating layer having high flexibility, adhesiveness and elongation properties. A second, protective layer is formed over the first, flexible layer by spraying over the first layer a liquid formulation which provides, when dried, a hard coating layer having high tensile strength and modulus, and low adhesiveness properties.

Abstract: Mixture of rubber and urethane binders for stable floor surfaces such as gyms, basketball courts, volleyball courts, pool decks and the like. The rubber and binder are pre-mixed and sealed in a vacuum sealed bucket or bag so that the mixture can be directly applied at a job site without additional mixing. A top coat having an 5 to 1 ratio of dyed rubber and binder forming a ½ thick surface can be used for sidewalks, running tracks and pool decks. A base layer having a 8 to 1 ratio of buffing rubber and binder can be used under the top coat for forming a shock resistant floor. Curing of the mixture on the floor surfaces can be done by adding water, through humidity or by natural rain.
