Forspec PROBOND 1100 is a high-strength, two-component epoxy paste supplied in bulk kit form for structural bonding, filling and repair work. It bonds freshly mixed concrete to sound, hardened concrete on horizontal and vertical surfaces and can be used for prepared static cracks, voids, small patch repairs, anchoring and epoxy mortar. Suitable substrates listed by the manufacturer include concrete, masonry, brick, block, stone, metal and wood where the surfaces are sound, dry and mechanically prepared. It may also be used for selected Forspec sheet-applied waterproofing membrane terminations and as a binder for high-friction surface treatments. This listing covers the bulk two-part kit only. PROBOND 1100 is identified in 10 kg and 20 kg kit sizes; only sizes shown in the variant selector are currently available to order. Do not use on cracks subject to movement. Do not thin with solvents or use for large or deep patch repairs.
  • Provides 55.2 MPa compressive strength and 29.02 MPa tensile strength.
  • Bonds freshly mixed concrete to sound, hardened concrete.
  • Suitable for both horizontal and vertical repair applications.

Technical and product guidance for the item you’re viewing.
  • Two-component, high-strength epoxy paste supplied as a bulk kit
  • Available in 10 kg and 20 kg bulk kit formats
  • 1:1 Part A to Part B mixing ratio for kit use
  • Bonds freshly mixed concrete to hardened concrete
  • 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
  • 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.
  • Product type: Two-component high-strength epoxy paste adhesive
  • Pack sizes: 10 kg and 20 kg bulk kits
  • Mix ratio: 1:1 Part A to Part B
  • Viscosity: 2,210 cPs at 25°C
  • Gel time: 25 minutes for 60 g mass
  • Working time: Approximately 45 minutes at 24°C
  • Tack-free time: 3-5 hours at 23°C
  • Application temperature: 5°C to 35°C
  • Service temperature after curing: -7°C to 50°C

  • Flexural strength: 35.37 MPa to ASTM D790-17
  • Shrinkage on cure: 0.2%
  • Hardened-to-hardened concrete bond strength: 15.6 MPa at 2 days; 20.1 MPa at 14 days
  • Shelf life: 24 months in original unopened packaging stored dry at 23°C and 50% RH
  • Potable-water contact: TDS states compliance with AS/NZS 4020 after curing
  • Limitations: Not for moving cracks, large or deep patch repairs, or thinning with solvents

Forspec PROBOND 1100 FAQs

What is Forspec PROBOND 1100 used for?
PROBOND 1100 is used for bonding freshly mixed concrete to hardened concrete, filling static cracks and voids, small concrete patch repairs, anchoring bolts or dowels, forming epoxy mortar and selected Forspec sheet-membrane termination details.
Can PROBOND 1100 repair moving cracks?
No. The TDS states that PROBOND 1100 is not suitable for cracks subject to movement. Active or structural cracks require assessment and a repair detail designed for the expected movement.
How is the PROBOND 1100 bulk kit mixed?
Pre-condition both components to 21-24°C, combine equal parts of Part A and Part B, then mix at 300-400 rpm for 2-3 minutes. Scrape the sides and base until the mixture is uniform and free of streaks, then apply immediately.
How should the substrate be prepared?
The substrate must be sound, dry and free from dust, oil, grease, curing compounds, sealers and weak material. Mechanically roughen smooth surfaces, vacuum clean thoroughly and allow new concrete to cure for at least 28 days.
Is PROBOND 1100 suitable for potable-water contact?
The TDS states that fully cured PROBOND 1100 is non-toxic for drinking-water contact and compliant with AS/NZS 4020. Confirm the current product documentation and project-specific requirements before use.
