Page 2 Recommended Mortar Mix  1 part cement  ½ part hydrated lime (optional)  Plasticiser to supplier’s instructions  5 parts sieved builder’s sand. Good mixing is critical, using a Cox mixing paddle is strongly recommended. Mix for 4 or 5 minutes to achieve a smooth, buttery mixture free of lumps. If mixing in a container, ensure that there is no unmixed material in the corners. Adding more water is no substitute for good mixing.

Use the Black Nozzle for pointing and the Grey Nozzle for grouting (mortars are too coarse to flow through the grey nozzle). If the gun blocks, then remove Barrel (steps 5‐6 from previous page); empty contents and try re‐mixing. If product will not flow properly; this may be due to:  Incomplete mixing  Insufficient plasticiser in mix  Sharp sand or gravel in the mix  Sand and cement premix separating in the bag (ensure when using pre‐bagged mix, that dry materials are mixed properly  Nozzle opening to fine. Avoid mortar contaminating the gun by regularly rinsing the rod and plunger assembly, always wash barrel and nozzle thoroughly after use. Adjusting the plunger The plunger is adjustable for wear. Tightening the nuts will squeeze the rubber to tighten its fit in the Barrel. ...
