Slide 10: Mixing
Construction Mixing Pre-mix both A & B components 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 Sika Corporation
Slide 11: Application: Broadcast Overlay
Construction Application Broadcast Overlay 1. Prime prepared substrate with Sikadur 22, Lo- Mod (or optional Sikadur 21, Lo-Mod LV) 2. While primer is tacky, spread the mixed Sikadur 22, Lo-Mod with a 3/16 in. notched squeegee 3. When material levels, broadcast the oven-dried aggregate slowly, all
Slide 12: Application: Broadcast Overlay
Construction Application Broadcast Overlay 4. Remove excess broadcast aggregate after epoxy has set • Ultimately the broadcast aggregate should be applied to excess at a rate of 2 lbs./sq. ft. Sika Corporation
Slide 13: Mixing: Epoxy Mortar
Construction Mixing Epoxy Mortar • Slowly add 3-6 parts by loose volume of an oven-dried silica sand to 1 part of mixed Sikadur 22, Lo-Mod and mix until uniform in consistency. Sika Corporation
Slide 14: Application: Epoxy Mortar
Construction Application Epoxy Mortar 1. Prime prepared substrate with mixed, neat Sikadur 22 Lo-Mod resin 2. While primer is still tacky, apply mixed epoxy mortar by trowel or vibrating screed Sika Corporation
