Parex Highway Framefix Mortar

Highway Framefix Mortar is a polyester based, rapid setting bedding mortar

Parex Highway Framefix Mortar is polyester resin based material used for the bedding and leveling of all types of frames in vehicular road surfaces, capable of withstanding the most demanding situations. The Product is supplied as a two pack system ready for onsite mixing consisting of two tins of base resin and two bags of catalysed filler. The mixed mortar will harden to give rapid strength gain reaching ~50 N/mm² in 1 hour, allowing road opening to vehicular traffic within 45 minutes to 1 hour. The placed frames will resist compressive and high impact loads. The chemical mechanism will continue at temperatures down to 0°C (Winter version), with only a small increase in hardening time. The hardened mortar is resistant to chemical attack from petroleum products and road salt. Two grades, Summer and Winter, are available.

  • Easy to use.

Application steps

SUBSTRATE PREPARATION

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 Parex Highway Framefix Mortar.

MIXING

Mixing must 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 Parex Highway Framefix Mortar, 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 filler has been added until the mix is powder free and uniform. The correct mixed consistency is the same as damp sand. The chemical reaction of setting is rapid.

Note: 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.

APPLICATION

Mix half or full packs only. Variations in mix ratio may alter mortar consistency and compressive strengths achieved.

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 and 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 some 20 to 30 minutes, depending on the surrounding ambient conditions.

CURING TREATMENT

No special curing is required at temperatures between 5°C and 35°C.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with Sika® Thinner C Cleaner immediately after use. Hardened / cured material can only be removed mechanically.
