Jointex CSG (Cold Store Grade)

Jointex CSG is specially formulated for fast curing repairs to concrete expansion or construction joints in cold stores and other low temperature environments. It results in a long lasting repair as it offers high strength and allows 100% movement within the joint.

Use on:Concrete. For other substances contact Polycote Experts.
Use where:Internal/External
Typical industries:Cold store fridges and freezers. Non toxic, but is odourous so OPEN food products should be sealed or removed until the vapour has dispersed
Type of job:Filling/repairing concrete expansion or construction joints

Approximate coverage:6 kg unit – 29 Linear metres @ 10 x 10mm
Cure time: Pedestrian traffic 1 hour @ 20°C

Application temperature:0oC to – 30°C
Depth of repair (1 layer):10mm – 25mm
Fully cured strength:26N/mm²
Number of parts supplied:2
Priming required:No. Only for very porous surfaces – use Polycote Primer CSG

Please consult the technical data sheet for full technical product data.

Preparation: Thorough substrate preparation is essential.

All joints must be clean, dry and free of dust, loose material or previous joint sealant. Shotblasting is recommended. A gas torch may be used to help remove oil or moisture from the surface.

If the edges have broken away – repair using Polycote Cretex® MC. Depending on the extent of the repair, the Cretex® material may be supported using a thin polythene-covered batten until firm, OR the joint may be totally filled with Cretex and re-opened once cured using a suitable width of diamond saw cut, providing a clean-edged joint. Please contact Polycote Technical Helpline for advice and the appropriate Data Sheets.

Jointex™ CSG does not normally require a primer, unless the substrate is very porous, in which case Polycote MC Primer CSG should be used.The prepared joint should be part filled using flexel or kiln dried sand, leaving a minimum depth of 10mm. Tape may be applied to mask the surface each side of the joint during pouring, but this should be removed as soon as material is placed.
Caution – Jointex™ CSG is methyl methacrylate based and has a characteristic odour during the vaporising of the solvent. Although non-toxic and non-injurious to health, this can cause tainting and OPEN food products should therefore be removed or sealed during and following application until the vapour has dispersed.

Mixing: Cool the materials in a freezer prior to mixing.Empty the resin Part ‘A’ into a clean plastic mixing container and add the complete quantity of hardener/filler Part ‘B’. Mix thoroughly to ensure complete dispersion of the hardener. For best results use a heavy duty slow speed drill with a mixing paddle.

Ensure thorough mixing as an unmixed product will result in a poor or non-cure situation.

Application: Apply immediately using a jug or suitable container to pour the mix directly into the joint.For a professional finish and maximum joint protection, fill to slightly above the level of the surrounding area, but not to the point of overflow. Once cured, the top of the filler may be chiselled flush to the level of the floor.
