F-52 SL 28

F-52 SL 28 Urethane Concrete Slurry Overlay

F-52 SL 28

Product Overview

F-52 SL 28 is a revolutionary formulation that allows longer working time with a snap-cure. It combines our urethane resin and Iso with our proprietary blend of portland cement, lime and fillers (PN 1352 SL 28). It has been formulated to provide the highest degree of impact and thermal shock resistance of any urethane concrete on the market. It’s low odor and easy application make it perfect for industrial and durable decorative applications.


F-52 SL 28 is most often used as a self-priming, Slurry Broadcast flooring system. It is used to achieve 1/8″-3/16″ in one pass or when a decorative broadcast element is to be included. F-52 SL 28 can also be used as a primer when concrete floors exhibit high moisture transmission levels. It can also be applied to green concrete.


The preparation method for each project is determined by a full understanding of the substrate to be coated, the chemistry of the coating system being used, the coating system thickness, and numerous other factors. The coating installer should fully read and understand ICRI Guideline NO.03732 and OSHA 29 CFR 1926.1153 before starting preparatory work. The aim, of preparing a substrate for coating applications, is to roughen the surface, remove weak layers, contaminants, dirt, debris and present a solid, clean, dry substrate for the primer. If unsure as to the level of preparation needed contact Polymer Nation at lab@polymernation.com.

The data below represents the most pertinent information needed by a professional installer to understand and efficiently install this material. The data was gathered at temperatures of 72-75 F and 30-50% RH. A wide array of independent and company test data has been compiled on this product but is too large to place on this Technical Data Sheet.

Mixing & Installation A mixture consists of 1.1 gal A, 0.75 gal B and 28 LB. of C (PN 1352 SL 28). Combine part A and B into a single container, large enough to accept the entire kit (1 mix equals 5.5 gallons when Part C is added). Premix liquids at 350 RPM for 1 minutes using an appropriate mixing blade or mixing machine. Pour material on to floor and spread to desired thickness using a screed rake or notched squeegee. Once material has leveled, back roll with a spiked roller to aid in the release of trapped air. If a broadcast has been selected, begin broadcasting evenly across the floor, following the same order in which the slurry was installed. Whenever possible, work the shorter distance not the longer as this will help keep a fresh edge and make for easier blending. Temperature should be descending , not ascending during application and cure of slurry. This is critical whenever a broadcast will not be cast into the wet slurry. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone.
