  • Patent number: 4146599
    Abstract: A device for applying exposed aggregate, which is utilized on the exterior and interior of building and home construction, as well as other structures, has been developed that consists of a rigid to flexible type backing with a resilient material such as foam or the like attached thereto forming the face of the device. It is essential to the device of the present invention that the resilient material forming the face of the device has sufficient resiliency to insure that aggregate that is placed thereon will not easily roll off the face of said device and yet in no way inhibit the adhesion of the exposed aggregate on a prepared surface when applied. In utilizing the device of the present invention and in carrying out the method of the present invention, aggregate is placed on the face of any number of devices of the present invention and such devices are used to directly apply aggregate to a surface such as a wall which has been prepared to receive exposed aggregate.
