Polymer Nation SP-15 100% Solids Epoxy Patching Paste
Product Overview
Polymer Nation SP-15 is a three-component, 100% solids epoxy patching paste. Mix 1 quart of Part A with 1 pint of Part B at a 2:1 ratio, then slowly add 3 lb of Part C (PN 1170) until the desired paste consistency is achieved. The cured patch is non-shrinking and has high compressive and tensile strength.
Uses and Benefits
Use for patching concrete holes, cracks, divots, and non-moving joints, and for feathered transitions between differing planes. One 0.5-gallon kit covers approximately 3.2 sq. ft. at 1/4 in. or 150 linear ft. of 1/4 in. x 1/4 in. joint. Apply at 60-90°F and use mixed material within 20 minutes.
