Moulding Chipping

[Sibbs]

I have used the arqadia moulding below for the first time and have noticed that it is chipping during the pinning process. I wondered if anyone has used this moulding and come across the same problem? If so, is it me causing it (too much pressure ???) or is it a common problem with this type of moulding? I use a M4 manual underpinner btw.

Moulding Ref: 404167000

Thnx

I have used a similar one in the past (402167015) which has a very thick coating and it chips a bit when cut.

These are very cheap mouldings and once my current stock is used up I will replace it with one from another supplier which will cost a little more but make a nicer job. I can get it at the same price though if I buy 30m at a time which would seem sensible.

Chipping on pinning rather than cutting? Where is it chipping? an image could be helpful
Cold weather can make the coatings on these mouldings much more brittle

Here is a photo fo the problem. When cutting it, it looks fine. Only when I took it out of the pinner that I saw the chipping. It may well be that it is just cheap. It is chipped on all but one of the corners.

Jonny, what is the new moulding you have come across?

These mouldings have a thick layer of compo which does chip easily especially when your workshops a bit colder
I've seen it sugested to warm the moulding first when its cold- wrapping in an old electric blanket for a while could be a solution

[Sibbs]

mmmm now there's an idea. I might try warming the ends with an old hairdrier first. Worth a go!

Going over the area with a marker pen of the appropriate colour before joining will not cure the problem, but will make it much less noticable.
