About the product
Product Overview
SP-20 is a flexible aromatic urethane that has extreme tensile strength with an A shore hardness of 75. It is easy to install, has little odor and has elongation of over 1000%. It far outperforms epoxy membranes in crack-bridging and as a waterproofing membranes under Polymer Nation floor systems.
Uses
SP-20 is primarily used as a membrane in parking decks and waterproofing applications. It can also be used as a flexible broadcast resin, as a binder in flexible floor applications and bulked up using fumed silica to make a flexible patching paste.
Preparation
The coating installer should fully read and understand ICRI310.2R-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. If unsure as to the level of preparation needed contact Polymer Nation at techservice@polymernation.com

Mixing & Installation
Combine all of part A and B into a single container, large enough to accept the entire kit. Mix at 350 RPM for 2-3 minutes using an appropriate mixing blade and making sure not to introduce excessive air into the solution. Pour the entire content from the container onto the floor and follow normal squeegee and back roll or cut and roller techniques. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone. When a thicker membrane is desired, mix PN 1620 S with a full kit. This mix will cover 160 square feet at 60 mils and spread evenly up to 200 mils.
