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.

Should the joint be deep, this can be filled with either kiln dried sand (commonly known as Block Paving sand) leaving a depth of no less than 10mm from the surface. Make absolutely certain that you carefully dust off the shoulders of the joint so that the Jointex can get a good clean surface to grip. Alternatively, our Foam Backing Rod is quicker and cleaner. This can then be inserted and ‘squashed’ into the joint, again, leaving at least 10mm down from the floor surface. Cut the nozzle at an angle to facilitate the placing of the compound and apply using a caulking gun. ­ Should a perfectly flat finish be required, the product can be pumped in sightly proud of the surface and once cured, cut through with a sharp knife / Stanley blade to leave a nice clean joint. Do not traverse until completely dry.
