- 1:1 dual cartridge, no site batching. Fits the FORSPEC Heavy Duty Dual Cartridge Gun
Coverage
A 600 mL cartridge runs about 16.7 m on a 3 x 12 mm crack or 5.0 m at 8 x 15 mm. Minimum 12 mm adhesive depth on gravity feed.
Not for
Cracks under 3 mm (use CRACKLOCK E400L) or over 8 mm (use PROBOND 1100), damp, wet or frosted substrates, concrete under 28 days old, below 5°C or above 35°C, drinking water, or waterproofing. Below 21°C, warm the product to 21 to 24°C first.
Tack-free and grinding times at 24°C.
Seals and structurally reconnects cracks from 3 mm to 8 mm wide
Tack free in 12-20 minutes and grindable one hour after application at 24C

Technical overview
Key applications
- Structural crack repair by pressure injection and gravity feed, 3 mm to 8 mm crack width
- Port injection repair of vertical cracks within the FORSPEC epoxy injection procedure
- Bonding freshly mixed concrete to hardened concrete
- Void and cavity filling in concrete, masonry and other substrates
- Binder for epoxy mortar and spall repair with kiln-dried aggregate
- Anchoring adhesive for bolts and dowels
- Binder for high friction surface treatments on concrete and asphalt
Surface suitability
- Concrete (minimum 28 days old, clean, sound, completely dry and mechanically profiled)
- Masonry (clean, dry and free of dirt, dust, laitance, curing compounds, oils, grease, wax, sealers and coatings)
- Asphalt (as the binder for high friction surface treatments)
Not for use in contact with potable water - the AS/NZS 4020 claim is withheld pending certification. Not a waterproofing membrane. Not for cracks narrower than 3 mm - specify CRACKLOCK E400L for 0.05-3 mm - and not for cracks wider than 8 mm, where PROBOND 1100 covers 3-20 mm. Not for application to damp, wet or frosted substrates; the substrate and the environment must be completely dry. Not for new concrete less than 28 days old. Do not apply below 5C or above 35C substrate and ambient temperature, and below 21C condition the product to 21-24C before use. Extremely cold product will thicken and will not flow correctly, and excessively warm conditions shorten working time. Do not dilute, extend, re-temper or add solvent under any circumstances. Do not leave a partially used cartridge with a loaded static mixer, because the material will harden in the nozzle. Spall mortar thickness must not exceed 70 mm per layer.

Frequently asked questions
-
What is Crack Pro 1200PS used for?
CompatibilityCrack Pro 1200PS is a high-strength epoxy injection resin for cracks 1-10mm wide - used for structural bonding, void filling, and welding cracked concrete back into monolithic structure. Suitable for slabs, beams, walls, and columns.
-
What's the cured strength?
PerformanceCrack Pro 1200PS reaches 55.22 MPa compressive strength (ASTM D695-15) - typically exceeds the parent concrete strength, restoring full structural load transfer across the crack. 100% solids, zero VOC.
-
How is it applied?
InstallationDual cartridge with static mixer (1:1 ratio) or gravity feed depending on crack orientation. Apply at 5-35°C ambient. Pot life is approximately 1 hour after mixing. Tack-free in 3-5 hours at 23°C, full cure 24 hours.
-
Viscosity and substrate?
CompatibilityViscosity 2,210 cps at 25°C - thick enough to fill gaps without running out. Bonds to concrete and masonry. Use with 10mm or 13mm Forspec injection packers and the INJEXA SWM injection pump.
-
Service environment?
PerformanceService temperature -7°C to +50°C once cured. Chemical resistant, waterproof, and clear-amber in appearance. 24-month shelf life when stored sealed.
