Sikadur 22 Lo-Mod: Epoxy Resin Binder
Sikadur 22 Lo-Mod is a 2-component, 100 % solids, moisture-tolerant, epoxy resin binder. It conforms to the
current ASTM C-881, Type III, Grade-2, Class-C and AASHTO M-235 specifications. Questions? Contact Us.
Sikadur-22 Lo-Mod may only be used by experienced professionals. Use neat as the binder resin for a skid-resistant broadcast overlay. Use also as the binder resin for epoxy mortar and concrete for patching and overlays.
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.
Preparation Work: Concrete – Should be cleaned and prepared to achieve a laitance and contaminant free,
open textured surface (CSP 3-4 as per ICRI) by blast cleaning or equivalent mechanical means. Steel – Should be cleaned and prepared thoroughly by blast cleaning to white metal finish.
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 3 parts by loose volume of oven-dried sand to 1 part of mixed
Sikadur®-22 Lo-Mod until uniform in consistency.
APPLICATION METHOD / TOOLS:
Broadcast Overlay – Prime the prepared substrate with Sikadur-22 Lo-Mod. While primer is still tacky, spread
mixed Sikadur®-22 Lo-Mod with a 3/16 in. notched squeegee. When material levels, broadcast the ovendried aggregate slowly allowing it to settle in the epoxy binder. Ultimately the broadcast aggregate should be applied to excess at a rate of 2 lbs./ft² Remove excess broadcast aggregate after epoxy has set. Priming is an optional step in the broadcast overlay applications.
Epoxy Mortar – Prime prepared substrate with mixed Sikadur 22 Lo-Mod or Sikadur 21 Lo Mod LV. While primer is still tacky, apply epoxy mortar by trowel or vibrating screed. Finish with finishing trowel. Priming is mandatory when using the 22 Lo Mod as an epoxy mortar.
