Surface 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™ EP. Cretex™ 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 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™ XFH does not normally require a primer, unless the substrate is very porous, in which case Polycote MC Primer Std 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™ 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 shake the container of resin to ensure dispersion of the contents, then empty the resin Part ‘A’ into a clean plastic mixing container and add the complete quantity of filler powder 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.
Jointex™ XFH has a characteristic odour during application which is nontoxic and non-injurious to health.
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.
Application Temperature
Temperature of application should be between 30˚C and –30˚C.
