Application:
Joint Preparation:
The joint sealing slots should be accurately formed. The concrete must be sound, dry, and free of oil and frost. The sealing slot surfaces must be well prepared to remove dust and laitance by grit blasting or grinding. The slot should be blown out with dry, oil-free compressed air just prior to priming. Care should be taken to ensure that the slot is formed to the required depth and any expansion joint filler is tightly packed. A tight fitting cord or bond breaker should be inserted at the base of the slot to ensure that the sealant only bonds to the joint sides.
Priming:
The prepared surface should be primed with SpECseal 200 Primer. The contents of the curing agent should be emptied into the base component and stirred with a spatula until the product appears uniform. The mixed primer should then be applied to the prepared substrate by a stiff brush at 10 m²/litre. If the primer appears to be absorbed into the surface easily, it will be necessary to apply a second coat once the initial coat is tack-free. SpECseal 200 must then be applied just after the primer becomes touch dry but before it has fully reacted. The sealant should be applied between 1 hour to 3 hours after priming. If the primer is left to dry longer than 3 hours, the surfaces must be re-primed prior to applying the sealant.
Application Temperature Range:
5°C to 50°C. Care should be taken to avoid application at ambient temperatures below 5°C, as frost may still exist in the slot and the cure time may be extended.
Equipment Cleaning:
Clean equipment with SpECseal Cleaning Fluid.
Usage Rates:
It is essential that adequate ventilation is provided and all personnel avoid inhaling the vapours produced. If working is necessary in a confined area, sealed respiratory equipment is strongly recommended.
