Sikadur®-22 Lo-Mod LT

Low-modulus, fast-setting, medium viscosity, urethane modified, epoxy resin binder for low-temperature applications

Sikadur 22, Lo-Mod LT is a 2-component, 100% solids, moisture-tolerant, urethane modified, epoxy binder capable of curing quickly at temperatures below 50F. It conforms to the current ASTM C-881* Type III, Grade 2, Class B & C and AASHTO M-235 specifications. * Except Gel Time

  • Fast setting for quick turn around
  • Meets 3 hr/1000 psi requirement when mixed as an epoxy mortar
  • Tolerant to moisture both before and after cure
  • Convenient easy mix ratio A:B = 1:1 by volume
  • Excellent strength development
  • Leveling viscosity for easy, efficient application of a broadcast overlay
  • Tack-free in 3.5 hours at 50°F (10°C)
  • Can condition material at elevated temperatures for faster cure rates

Consumption

Coverage

1 gal. yields 231 in3

For traffic overlay - 1 gal yields ~32 ft2

Mortar Binder - 1 gal. of mixed Sikadur® 22 Lo-Mod LT with the addition of 5 gal. by loose volume of an oven dried sand, yields approximately 808 cu. in. of epoxy mortar.
Application steps

SUBSTRATE PREPARATION

Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes and any other contaminants.

Concrete - Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by blast cleaning or equivalent mechanical means.

Steel - Should be cleaned and prepared thoroughly by blast cleaning to white metal finish.

MIXING

Pre-mix each component. Proportion equal parts by volume of Component ‘A’ and ‘B’ into clean pail. Mix thoroughly for 3 min. with Sika paddle on low-speed (400-600 rpm) drill until uniformly blended. Mix only that quantity that can be used within pot life.

To prepare epoxy mortar - Slowly add 5 parts by loose volume of oven-dried sand to 1 part mixed resin
