CCS Grout, Polyurea LWL

A two-component, long work life elastomeric polyurea system used for interior and exterior joint nosing, spall repairs, and concrete restoration. It can be applied as a neat binder for crack and joint filling, or blended with aggregate for mortars, concretes, and flowable grouts.

·         Polyurea LWL Part A (resin)

·         Polyurea LWL Part B (hardener)

·         Polyurea Primer (required for damp surfaces or maximum bond on dry surfaces)

·         Aggregates:

o        For mortars: High silica sand (>85% SiO₂), washed, kiln-dried, graded.

o        For concretes: 1:1 blend of 3/8" gravel and #16 or #20 mesh sand.

·         Rebuilding joint nosing

·         Repairing spalled or deteriorated concrete

·         Gravity filling of saw cuts, control joints, and non-structural cracks

·         Mix Ratio: 1:1 by volume (Part A:Part B)

·         Primer Required: Yes, on damp surfaces or for maximum bond strength

·         Installation Temperature: Minimum 50°F

·         Cure Temperature: Minimum 40°F

·         Gel Time: ~25 minutes (60g mass)

·         Touch Dry Time: ~1.5 hours

·         Hard Dry Time: ~5.5 hours

·         Substrate Prep: Clean and sound; 250 psi minimum tensile strength for concrete; SSPC SP 5 for steel

·         Aggregate Use: Max aggregate size not exceeding 1/3 of installed thickness

·         Primer Application: 8–10 mils thickness (coverage 160–200 sq ft/gal)

·         Cured product is UV resistant and retains elastomeric properties without embrittlement

·         Resistant to vehicular impact, abrasion, automotive/aircraft fluids, and deicing chemicals

·         Not resistant to hydrocarbon solvents

·         No VOCs; environmentally safe

·         Do not thin or add solvents

·         Shelf life: 1 year in original, unopened containers stored between 60–90°F

·         Clean tools with acetone or appropriate solvent before material cures

Requires nitrogen blanket for preserving partially used Part A containers
