U-45
About the product
U-45 is primarily used as a clear sealer over concrete or cementitious surfaces due to its excellent wear and abrasion resistance. It is reduced in the field with xylene to achieve application viscosity; this is usually done at a ratio of 1:1 by volume. Solvents with low flash points (i.e., acetone) are not recommended to use as a reducing agent due to rapid evaporation rates; this can be problematic for both application and finish properties. A minimum of 2 coats is recommended for complete sealing of the substrate.
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 material needed from the container onto the floor and spread with a 5-7 mil squeegee. Back roll perpendicular to evenly spread the material. Strike off the material in the same direction as material was squeegeed. Material can also be bucket-rolled using a 3/8″ nap roller cover. For a non-skid finish add 288 grams per 3 gallon kit of PN 1337 S (1-12 oz cup struck off at the top) or 4 lbs. of PN 1335 AO and stir to completely incorporate. Recoat within 10 hours. Clean tools with a solvent similar to Xylene or Acetone. PN C-55 can be used to accelerate the cure.
