Structural concrete and concrete topping shall include expansion joints which shall be filled with Miracote Mirathane 500 or MC-5 joint filling compound or approved equal. Minimum pitch of 1/4 inch per foot. Covering on-grade floors is generally not recommended. If application is over an on-grade condition, the slab shall have a functioning vapor retarding membrane or sheet beneath slab, and slab should be properly vented. Consult Crossfield Products Corp.)
Floor drains - Division 15.
(Note to Specifier: Floor drains, clean-outs, etc. should be of the "floor-flange" type as manufactured for use with composition floors by most major drain manufacturers. Drain flange shall be finished with substrate. Bi-Level drains shall be used with mortar bed installations)
Insulation, vapor barrier and protective waterproofing
(Consult Crossfield Products Corp. for specific recommendation)
Sheet metal flashing
(Note to Specifier: Sheet metal flashing shall be minimum 26 gauge galvanized. All joint or seams shall be overlapped approx. 3" and caulked with Miracote Mirathane 500 flashing paste or approved equal, installed in compliance with all building code requirements. )
Plywood substrate including framing and blocking
(Note to Specifier: Plywood substrates which are to receive thin-set tile applications shall be a minimum 5/8 inch ( preferably 3/4 inch) exterior grade. Covered with 2.5 expanded metal lath filled with Miracote Repair Mortar. Plywood shall be supported 16" on center and properly blocked. Plywood shall be attached with either screws, screw type or ring shank nails. Plywood substrates which are to receive mortar bed applications shall have slip sheet cleavage membrane both below and above waterproof membrane application. Special care shall be taken to insure waterproof membrane extends up vertical surfaces a minimum of 3" above finish elevation of tile surface.
Slope for drainage
(Note to Specifier: Allow minimum 1/4 inch per foot slope to drain. This can be provided for in the substrate or by application of Miracote Repair Mortar. Care must be taken to provide adequate elevation at thresholds to provide proper slope to drain.)
General: Submit the following in accordance with Conditions of Contract and Division 1 Specification Sections.
Product Data: Submit manufacturer's technical data, application instructions and general recommendations for the waterproof neoprene composition fracture Resistant waterproof membrane system specified herein.

PART 2.00 PRODUCTS
Troweled waterproof neoprene composition fracture resistant waterproof membrane system shall be Miracote Liquid Membrane FR below tile waterproof membrane as manufactured by Crossfield Products Corp.; Rancho Dominguez, California; Roselle Park, New Jersey; Hinsdale, Illinois; Moss Point, Mississippi; Tacoma, Washington; Marietta, Georgia.
The trowel applied waterproof neoprene composition fracture resistant waterproof membrane system shall be composed of a (slip-sheet - for mortar bed applications over plywood or lightweight concrete), waterproof membrane, and protection surfacing (slip sheet - over protection coat for all mortar bed applications), and shall conform to the following standards:
1.) All resin binders and all rubber emulsions shall be compounded with neoprene or E. V. A. Polymer liquids and neoprene shall have a minimum polymer or neoprene solids content of 35% when tested by the dry cup method.
2.) Aggregate for protection coat surface coating shall be suitably graded, fine trap-rock passing a #20 mesh sieve and retained on a #40 mesh sieve.
3.) Slip-Sheet (where applicable) shall consist of an asphalt-saturated glass fiber matting weighing not less than 11 lbs. per 100 square feet and containing no rag or organic fibers.
4.) Fabric used as reinforcement for waterproof membrane or protection coat (as applicable) shall be 7-1/2 oz. woven polypropylene fabric, or when used to reinforce liquid membrane shall be ¾ oz loose woven fiberglass mat or as recommended by the material manufacturer.
