Progrout Handy Hints:

1. Getting the correct mix can take some practice depending of type of sand and finish required due to regional variations in building sand.

2. Hydrated lime can be used as an alternative to plasticiser.

3. The mortar mix needs to be fairly creamy when mixing in the bucket. If it will not pump, it is too stiff or there is not enough plasticiser/lime.

4. Periodically stir the mortar in the bucket to prevent it becoming stiff.

5. Smaller nozzles require a slightly wetter mix. If the nozzle blocks the mix is too stiff. If the nozzle drips, the mix is to wet.

6. Before removing the nozzle to clear blockage, first try immersing the tip in a bucket of water and reverse the motion of the drill for a few seconds, suck up a little water then revert to forward motion

7. Wetter mixes will dry slightly weaker, e.g. a 1-4 mix will dry to a 1-5 mix

8. ALWAYS use fresh cement and clean equipment

9. Building sand used MUST be sieved for successful pointing. NOTE: Some cements are now manufactured with their own plasticser and no further additives should be necessary.

10. Wet inside of hopper before use and do not overfill.

11. 5mm, 8mm, 10mm and 15mm diameter nozzles are available if required. Use more cement and plasticser to form a creamier wetter mix to ensure there are no lumps in the sand or cement.

12. Wash out the hopper with a hose using a spray attachment after finishing work or leaving for long periods between jobs.

13. Do not forget to lubricate the bearing housing daily using a general purpose grease. Periodically the gearbox will benefit from internal cleaning and re-lubricating.

14. To prevent build-up of mortar around the outside of the bearing housing and to increase life, thinly smear around the top with grease.

15. Always fully charge batteries before commencing work. New batteries improve significantly after a few discharges and recharges.
