Expert Verdict — Reviewed by the SuperArbor Pro Desk
Sikadur-31 Hi-Mod Gel is the standard pick when a structural epoxy must stay put on vertical or overhead concrete because its gel consistency resists sag. Mix full kits at the stated ratio, avoid extending it with solvent since it is 100% solids, and apply within the data-sheet pot life. For horizontal crack injection or bonding fresh patches, this paste doubles as a reliable interface binder.
Epoxy paste can cause skin and eye irritation and sensitization; wear gloves and eye protection and review the Sika safety data sheets before mixing.
