Stucco Finish Application:
Any nish can be applied to an Isokern replace however with each nish there are different application techniques which
can help with the longevity of your nish. When applying a stucco nish to the Isokern material, it is recommended that a scratch
coat is applied rst to provide a strong base for the system. It is embedded in a wire lathe (not felt backed) which is screwed with
care to the replace unit. Use 1 1/4” Tapcon screws to attach the lathe to the rebox using the minimum amount needed to secure
the wire lathe. A brown coat is applied next to create an even surface for the nish coat. The nish coat is applied last, creating the
decorative nish on the wall surface.
