Expert Verdict — Reviewed by the SuperArbor Pro Desk
Sikadur-33 is the paste you choose when you need a port-sealing surface coat that reaches injection strength fast, so crews can inject the same day. For wide or overhead cracks, keep the paste layer tight and uniform and begin injection at the 1-hour mark on small test ports before committing the whole crack.
Epoxy resins can cause skin sensitization; wear gloves and eye protection and follow the product safety data sheet.
