1 — clean out joints to a depth of at least 30 mm (minimum joint width 5 mm). The surface to be joint-fixed should be cleaned of all impurities before work commences. Adjoining surfaces that are not to be joint-fixed are taped off.

2-4 — pour the filler components (25 kg sack) into the mixing process. Whilst mixing, slowly add the separately packaged resin/hardener component (2 plastic bottles stuck to each other) completely into the mixture. After mixing for 3 minutes add approx. 2 litres of water and continue mixing well for at least 3 minutes.

5 – pre-wet the surface. Porous surfaces as well as higher surface temperatures require more intense pre-wetting.

6 – apply the mixed pavement fixing mortar onto the well damp surface and work it carefully into the joints using a squeegee/rubber slider. Application time at + 20ºC is approx. 20-30 minutes.

7-9 – after approx. 10-15 minutes the excess mortar on the surface of the stones can be swept off carefully with a large, coarse broom. Then use a soft, hair broom to do a final cleaning until all residual mortar has been removed from the surface. The correct moment for sweeping, is when white smears no longer form on the stone surface during sweeping. Sweeping should be done diagonally to the joint. Do not re-use swept off material. During initial period a very thin film of epoxy resin remains on the stone surface and intensifies the color of the stone and protect it from dirt. This film, however, disappears from the surface in open weather and through abrasion in the coming months.

10, 11 – the freshly jointed surface needs to be protected against rain for the next 12-24 hours. The rain protection layer must not be laid directly onto the paved surface, this is to ensure sufficient air circulation. Safe rain protection is afforded by the specially developed ROMEX protective surface mats, that can be simply laid on the surface.
