Abstract

A method of applying a bound particulate rubber outdoor surface comprises the initial step of providing a prepared base onto which the surface is to be applied. A primer layer is applied to the base, and is composed of a mixture including water such that the layer is wet when applied and dries as the water in the mixture evaporates. A fluidized stream of particulate rubber is directed onto the primer layer before the primer layer dries so that a layer of particulate rubber is formed on top of the primer layer and settles at least partially in the primer layer. Thereafter, the primer layer is allowed to dry before application of a binder layer over the particulate rubber. The binder layer also is composed of a mixture including water. A fluidized stream of particulate rubber is then directed onto the wet binder layer so that a layer of particulate rubber is formed ont op of and settles in the binder layer. An additional binder layer is applied over the layer of particlate rubber after the binder layer immediately beneath the layer of particulate rubber dries, and these last two steps are repeated until a surface of desired thickness is formed. A latex-bound, particulate rubber outdoor surface is also disclosed which includes alternate layers of binder and particulate rubber, wherein each layer of particulate rubber is at least partially embedded in the binder layer immediately therebelow as well as in the overlaying binder layer.
