Rio-Crete Smooth Finish Urethane Mortar

Rio-Crete Smooth Finish Urethane Mortar

RIO-CRETE MF is a medium to heavy-duty seamless flooring system typically installed at 3/16” finished thickness. RIO-CRETE MF is tough and withstands thermal shock, impact, abrasion and chemical exposures. RIOCRETE MF provides a smooth cleanable profile with a matte finish. RIOCRETE MF is formulated with a natural additive to be resistant to fungi growth per the industry standard ASTM G-21.

1. To prevent lifting or delamination, keyways (minimum 5/16” wide x 5/16” deep) must be cut at all terminations, joints, columns, doorways, and drains.
2. Clean sand and dust from prepared concrete where the floor is to be installed.
3. A cove base material can be used to install a cove and/or base as required. The cove/base can be installed before or after the installation of the RIOCRETE MF depending on the specification and or the desired result.
4. Pour ½ Gallon Part A into a 5 gallon mixing pail.
5. Add 3 fluid oz. liquid pigment to Part A and mix about 15 seconds using a ½” drill and jiffy-type mixing paddle.
6. Add ½ Gallon Part B and mix another 15 seconds.
7. Gradually add all contents of a RIOCRETE MF Filler into the liquid mixture and blend thoroughly until all particles are wetted out, normally about two minutes. DO NOT BLEND AGGRESSIVLY OR INTRODUCE AIR.
8. Immediately after mixing (within 3 minutes), spread the mixed RIOCRETE MF onto the floor at the desired thickness, using a cam rake or trowel. Typically 3/16”.
9. Lay abutting edges within 10 minutes to ensure a clean edge. A “wet edge” installation is imperative during large placements to avoid lines and ridges in the finished floor.
10. Evenly apply to desired thickness while trying to keep cam rake lines to a minimum. Backroll across slurry with spike roller to help release trapped air and blend cam rake lines. Further roll with loop/texture roller perpendicular to cam rake lines over entire floor to
even and settle slurry.
11. Use of a self-leveling cement smoothing toll will aid in the removal of rake marks.
