Hello all.

Please advise on the best hand saw to cut uPVC fascias. I assumed I could buy a suitable toot pitch blade for my circular saw (I need to cut an angle along a ~3m piece, to match the roof pitch).

However on reflection, I think a hand saw is the safer option.

Thanks in advance.

I fitted uvpc fascia boards, solid type and used standard handsaw, it cuts well and I secured it with stainless steel screws and then applied white silicone rubber in the heads as I wasn't keen on those plastic headed nails sold for fixing.

Sharp, fine tooth hardpoint saw does the job well. Given how cheap the things are from the usual DIY suppliers its well worth buying new if yours has been around for a while. Fine tooth gives better control on breakthrough but the coarse tooth one does well enough if you support both sides..

Best tool I've seen for trimming down along a length is the 18 V battery Makita circular saw with the thinnest blade. Builder who helped me with a job last year had one and it did a super job. He really rates the thin blade but said it doesn't fit a normal circular saw. Having seen that one in action I'd buy one tomorrow despite the price if I didn't already have a decent Hitachi mains powered one that will almost certainly see me out. Don't advise trying a normal circular saw or even the small plunge saws. Can be done but its easy to end up with a spectacular mess. I did get good results with my small plunge saw after "some practice" on the stash of offcuts left from the main extension job.

The half circle blade in a multi-tool does a decent job but its slow and the swarf very fine making it four times as as pestiferous as the usual stuff.

Fine pitch hardpoint as said above will have no problems with it.

I don't change blades in my table, sliding compound or cordless circular saw when I use any of those on uPVC so whatever you have in your saw should be OK unless its blunt. If using power saws cut from the back so you don't risk chipping the edge unless using a downcut blade in a jig saw.
