A tough single pack polyurethane joint sealant. Flexible and chemical resistant. Used in hundreds of industrial areas. Very easy to use.
Concrete, brickwork, blockwork, stone, timber and other porous substrates should be primed with Polycote SP Primer prior to application of Jointex™ SP. No primer is required for application to non porous surfaces such as cast iron, galvanised steel and aluminium. Painted metal surfaces do not normally need priming, but apply to a test area first to ensure compatibility.
Jointex™ SP is mid grey in colour.
Jointex™ SP is supplied in 380ml cartridges, 12 cartridges per pack, complete with polyethylene nozzles.
Thorough joint preparation is essential.
Any previous joint filler should be removed and all loose debris raked out. The prepared surface should be dry, clean, sound and free of flaking or loose material. Porous surfaces should be primed with Polycote SP Primer – see ‘Suitable Substrates.
A single coat of Polycote SP Primer should be applied if appropriate using a clean dry brush and allowed to dry for 60 minutes. Jointex™ SP should then be applied as soon as possible and in any case within 8 hours.
1. Cut the cartridge tip carefully.
2. Attach the nozzle and cut to required bead size.
3. Apply using a standard sealant gun.
4. For bonding GRP products, apply 1–2 continuous beads to the back and press firmly into place immediately.
