Abstract
An improved terrazzo floor or wall construction of reduced thickness bonded and adhesively secured to an underlying sub-surface through the medium of an intermediate liquid impermeable sheet. A frangible terrazzo veneer is bonded to the liquid impermeable sheet and the sheet in turn is adhesively secured to the underlying sub-surface by a rubberized asphalt or the like elastomeric material to permit lateral movement of the sub-surface relative to the said facing veneer to obviate cracking of the veneer due to cracking or lateral movement of the sub-surface.
Claims17
In combination, a sub-surface, a sheet of flexible pre-manufactured liquid impermeable material, an elastomeric adhesive securing said sheet to said sub-surface, a frangible thin facing veneer, and a bonding agent securing said facing veneer to said liquid impermeable sheet, said bonding agent compatible with said sheet material and with said facing veneer whereby said facing veneer is rigidly secured to said liquid impermeable sheet, which facing veneer is applied in the form of a wet slurry mix, said elastomeric adhesive permitting lateral movement of said sub-surface relative to said facing veneer.
A method for attaching a frangible thin facing veneer to a planar sub-surface comprising:
- causing adherence of a pre-manufactured liquid impermeable sheet to a sub-surface by an adhesive layer and applying said frangible veneer thereover while in a wet slurry state and bonding said frangible layer to said liquid impermeable sheet through a bonding agent compatible with said impermeable sheet and facing veneer whereby said frangible layer is rigidly secured to said liquid impermeable sheet, and wherein the adhesive is selected so that said adhesive layer will allow lateral movement of said sub-surface relative to said frangible thin veneer.
