Colas Resin 4

It displays rapid strength gain and cures quickly to allow road opening in the shortest time possible, usually within one hour. It reaches a typical strength of 50N/mm² in one hour under normal conditions.

• Re-bedding of raised manholes
• Support of road furniture
• Bedding of frames in new roads
• Most rapid opening of newly placed frames and road furniture

Laitance and all loose material including dust, oil and grease should be removed in order to produce a sound substrate. Any loose brickwork should be re-bedded using a slightly resin rich mortar mix.

To achieve the most consistent mortar mix, mechanical mixing is recommended. Mixing may be carried out in the plastic package pail or a similar suitable mixing vessel. Suitable mixers include a slow speed high torque drill and Mortar Stirrer. For full pack mixing of Colas Resin 4 pour all of the resin contained in the two tins within the pack into the mixing pail. Slowly add the catalysed filler while continually mixing. Continue mixing after all the catalysed filler has been added until the mix is powder free and uniform. The chemical reaction of setting is rapid. The mixed mortar should be placed immediately after mixing. The working time may be extended in cold ambient conditions and may be shortened in hot ambient conditions.

Set suitable levelling shims onto the working surface ready to receive the frame or unit. Place the mixed mortar onto the prepared surface and lower the frame or unit onto the mortar and knock down onto the pre-set shims to line and level.

The bed thickness applied in a single application should be between 5mm to 50mm. Thicker support beds can be achieved by applying further material as soon as the lower bed has hardened sufficiently not to distort under the additional work. The placed mortar will have hardened sufficiently to carry out further work, such as haunching, within 20 to 30 minutes depending on the surrounding ambient conditions and product grade. Clean tools with Solvent before mortar has started to harden.

Curing: No special curing is required at temperatures between 5°C and 35°C. For placing temperatures outside this range contact our National Sales Office on 01925 632616.
