Problem

Remedy

1. Unknown floor conditions

· Start with a medium or soft diamond bond.

2. Soft, open and porous floors

· Start with a hard bond or medium hard diamond bond.

3. Very hard and trowelled floors

· Start with a medium soft, soft or very soft diamond bond .

4. Diamond glazing

· Choose a softer diamond bond.

· Increase grinding pressure.

· Change tool speed.

5. Quick diamond consumption

· Choose a harder diamond bond

· Reduce grinding pressure

· Mount 6 diamonds per carrier instead of 3

6. Machine moves hard or switches off

· Reduce grinding pressure, remove saddle weight.

· Reduce tool speed

· Choose a different tool

· Mount a full diamond set.

7. Coating removal

· Work with 50% overlap to get a better result

8. Scarifying & shot blasting

· Floor grinding achieves a more uniform surface compared to shotblasting and scarifying.

9. Hard Floors: Grinding becomes slow

· Use a soft bond diamond

· Use a higher grit diamond

· Vary the tool speed

· Vary the weight

· Use sand or concrete dust

· Use wet grinding

10. Soft Floors: Diamonds wearing fast

· Use a hard bond diamond

· Reduce the weight

· Increase the tool speed

· Increase the forward movement

· Use a full set of diamonds

11. Bolts and metal object in the floor

· Any objects in the floor must be cut or removed to prevent damage on machine and tools.

12. Cracks in the floors

· Use cement based filler, for holes and close joints
