What is the best way to seal joints on fibre cement sheets before painting?

I would have to say some form of flexible sealer if you don't want to use cover strips.
no more gaps of sicaflex or something suitable.
any hard filler like puty or bog will get spat out sooner or later.
Unless it is interior(ISH) then you could set it like plaster, but recessed edge boards would be required. then its likely to crack anyway.

have found in the past that something like no more gaps still leaves a line in the material ( perhaps it was just me ) so would be interested in how to put it on without leaveing the crease line

David,
if you want a seamless joint then you will need recessed edge sheets, villaboard for interior or harditex for exterior. The recessed edges are then filled with a combination of reinforcing tape and jointing compound (different systems for interior and exterior).

If you are using Harditex aka blue board the best product I found is called GranoFlex add 10-15% of off-white cement (if you use grey cement it will turn dark grey or black and may be more difficult cover when you paint).
That product adhere incredibly well, make sure you clean your tools properly and when dry it remains a bit flexible so it does not crack. The finish is not very smooth and if you dont use a texture coating you may need to fill it up before painting.
Only problem is that it is only sold in 15kg drums so if just have 2 or 3 sheets to join it can be a bit expensive.
For indoors or villaboard James Hardie have a joining compound that works well, forgot its name.
Hope that helps |

Cheers | Actually, they are just interior Hardiflex(?) sheets 2400x1200. Some of the existing sheets have cover strips and that's OK for that part of the house.
Feature walls don't look all that good with cover strips, Thanks for the suggestio.
