Overview & Features
- Fills prepared static cracks and voids from 3–20 mm
- Suitable for horizontal and vertical applications
- Low 0.2% shrinkage on cure
- Suitable for selected Forspec sheet-membrane terminations
- Compliant with AS/NZS 4020 for potable-water contact after curing
- Not suitable for cracks subject to movement
Application Guide
- 1. Confirm the repair is suitable for a rigid epoxy. Do not use PROBOND 1100 on cracks subject to movement.
- 2. Allow new concrete to cure for at least 28 days. Mechanically remove dirt, dust, curing compounds, oils, grease, sealers, coatings and weak material.
- 3. Rough-grind, scarify, bush-hammer or otherwise texture smooth surfaces, then vacuum clean. Both bonding surfaces must be sound, dry and contaminant-free.
- 4. Pre-condition Part A and Part B to 21–24°C. Combine equal parts in a clean pail and mix at 300–400 rpm for 2–3 minutes, scraping the sides and base until uniform and streak-free.
- 5. Apply immediately while workable. At 24°C, the stated working time is approximately 45 minutes and reduces as temperature rises.
- 6. For static cracks and voids, inject or gravity-feed the mixed adhesive into prepared openings from 3–20 mm wide. Fill larger voids in layers to limit trapped air.
- 7. For anchoring, partially fill the prepared hole, insert the bolt or dowel with a slow twisting motion, remove excess and leave undisturbed. For small spall repairs, cut to sound square edges, press in the adhesive and trowel flush.
- 8. For selected Forspec sheet-membrane terminations, prepare the reglet, install the membrane to its current TDS, fill and trowel the termination flush.
- 9. Protect the repair until fully cured before loading, traffic, grinding, overcoating or flood testing. Cure varies with temperature; verify the current TDS before use.
- 10. Clean uncured residue from tools with a mild solvent. Cured epoxy requires mechanical removal.
