SUBSTRATE PREPARATION
Clean and sound surface shall have at least a wood float finish. All holes, joints, and cracks and honeycombs in concrete or masonry surfaces shall be filled with an approved grout and allowed to cure. High spots in concrete or masonry surfaces shall be cut off or ground down to prevent damage/puncture to the pedestal base.

For a bonded application, the pedestal may be adhered to the substrate with an approved adhesive. The first paver shall be installed to the correct elevation before using a levelling device to serve as a reference. Subsequent pavers shall be installed and checked to ensure consistent and correct elevation, till a sturdy and rigid raised flooring is obtained, free of rattling, squeaking or other noises.
