1. Mixing

Pour the 55 lbs filler material into the mixing tub and start the mixing process. Whilst mixing, slowly add the ROMPOX® DRAIN components into the mixture. Use professional agitator or rotary-drum mixer / compulsory mixer.

2. Add Water

After mixing for 3 minutes add 2 litres | 0.53 gal of water. Fill up the two previously emptied resin/hardener bottles with 1 litres | 0.26 gal of water, close, shake vigorously and add the contents of the bottle to the mixture. Continue mixing well for at least 3 minutes.

3. Pre-Wet

Intensely pre-wet surface. Porous surfaces as well as higher surface temperatures, require more intense pre-wetting.

4. Application

Apply the mixed pavement jointing mortar onto the pre-wetted surface by pouring out in three or four spots to optimise flow capacity. Work carefully into the joints using a squeegee/rubber slider, ensuring it passes deep into the joints and fills them completely.

5. Sweep Off

After approx. 10 minutes the excess mortar on the surface of the stones can be swept off carefully with a large, coarse broom. The correct moment for sweeping, is when white smears no longer form on the stone surface during sweeping.

6. Final Cleaning

Finally, use a soft hair broom to do a final cleaning until all residual mortar has been removed from the surface. Sweeping should be done diagonally to the joint. Do not re-use swept off material.
