Jointex XFH is a two part MMA based flexible jointing compound combining a resin and a hardener. It is specially formulated to achieve a very rapid cure at normal ambient temperatures. It offers high strength with excellent elongation characteristics, allowing up to 150% movement within the joint.
Typical Uses
Jointex XFH is ideal for rapid repairs to concrete expansion or construction joints, minimising disruption to busy areas of continuous traffic due to its outstanding speed of cure. Typical applications include factory and warehouse floors.
Suitable substrates
Jointex XFH may be applied to old and new concrete.
Colour
Jointex XFH is grey as standard. Other colours are available to order subject to minimum quantity.
Packaging
Jointex XFH is supplied in pre-measured quantities as a two part 4L unit, comprising a resin (Part A), and a hardener (Part B).

Please consult the technical data sheet for full technical product data.
Preparation
All joints must be clean, dry and free of dust, loose material or previous joint sealant. A gas torch may be used to help remove oil or moisture from the surface.
If the edges have broken away – repair using Polycote Cretexâ„¢ EP. Cretexâ„¢ MC may be used if a faster cure is required. 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 Cretexâ„¢ 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 XFH does not normally require a primer, unless the substrate is very porous, in which case Polycote MC Primer Std should be used. Insert Foam Backing Rod into the prepared joint, leaving a maximum depth of 20mm. 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 XFH 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
Thoroughly mix the container of resin to ensure dispersion of the contents, then pour the entire hardener ‘Part B’ into the resin ‘Part A’ and 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 the level of the surrounding area, but not to the point of overflow.
Application Temperature
Temperature of application should be between 3ËšC and 30ËšC.
