SP-24 Flexible Aliphatic Urethane Wear Surface
SP-24 is a flexible aliphatic urethane designed to provide a semi-flexible wear surface as part of a traffic coating system or waterproofing floor system.
Overview
SP-24 is a flexible aliphatic urethane designed to provide a semi-flexible wear surface as part of a traffic coating system or waterproofing floor system. It is easy to install, has little odor and provides a UV stable, tough, abrasion and chemical resistant topcoat.
Uses and Benefits
SP-24 is primarily used as an intermediate and topcoat in parking deck and waterproofing applications. It can also be used as a binder for floor applications that require more resiliency than epoxy floors typically can provide.
Limitations
SP-24 is designed to be applied between 15-25 mils as an intermediate or topcoat. Ideal application temperatures to be between 60-90°F. Cooler temperatures will increase cure times. Warmer temperatures will decrease working and cure times. Verify that substrate temperature is above 5 degrees of dewpoint during application and cure of material to avoid a potential amine blush.
Preparation
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. 310.2R-2013 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.

Mixing & Application
Do not split kits. Combine all of part A and B into a single container, large enough to except the entire kit. Mix using a 350 RPM mixer using an appropriate mixing blade for 1.5 – 2.5 minutes making sure to not introduce excessive air into the material.
Disposal: Dispose of material, containers, solvents, etc., per Federal, State and local guidelines, rules and laws.
