_{* Except gel time}

Epoxy resin

24 months in original, unopened containers

• Store dry between 4–35 °C (40–95 °F)
• Condition product at temperatures between 18–29 °C (65–85 °F) before using

<20 g/L

2,000 cps

* (H-22 wheel; 1000 g weight for mortar / C-17 wheel, 1000 g weight, neat)

Material cured and tested at the temperatures indicated and 50 % R.H.

Component A : Component B= 1:1 by volume.

• Epoxy binder: 1 L of Sikadur®-22 Lo-Mod FS = 1 m² of epoxy binder at 1 mm thickness (40 mil)
• Mortar binder: 1 L of mixed Sikadur®-22 Lo-Mod FS with the addition of 5 L by loose volume of oven-dried sand will provide 0.0034 m³ (3.4 L).

Substrate must be clean and structurally sound. It may be dry or damp, but free of standing water. 

Remove Remove any dust, laitance, grease, oil, dirt, curing agents, impregnations, wax, foreign matter, coatings, contaminants and any other bond inhibiting material.

Concrete: Should be cleaned and prepared to achieve a laitance and contaminant-free, open and textured surface (surface profile CSP-3, minimum) by blast-cleaning or equivalent mechanical means.

Steel: Steel substrates must be cleaned and prepared thoroughly by blast-cleaning to white metal finish (SP-10).

Pre-mix each component of Sikadur®-22 Lo-Mod FS separately. Empty component B in the correct mix ratio into the component A container. Mix the combined components for three (3) minutes, using a low-speed drill (300 - 450 rpm) to minimize entrapping air. Use a Jiffy® or Exomixer® type mixing paddle (recommended model) suited to the volume of the mixing container. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once, to ensure complete mixing. When completely mixed, Sikadur®-22 Lo-Mod FS should be uniform in colour and consistency.

Do not mix more material than can be applied within the working time limits (pot life). 

Epoxy mortar preparation: Slowly add five (5) parts by loose volume of oven-dried sand to one (1) part of mixed A and B component (binder).

Uncured material can be removed with appropriate solvents, such as xylene. Strictly follow solvent manufacturer’s warnings and instructions for use. Cured material can only be removed mechanically.
