I can get them basically back together by gluing but that leaves some dents (the dog chewed them!) and splits that need filling.
So what would people suggest for finishing the repairs (and/or some of the initial gluing), am I after a glue that can fill cracks or am I after wood filler (or some other sort of filler)?
I'm concerned that wood filler may not adhere well enough on the fairly small dents and splits. On the other hand I can't find any glue that seems to have the properties I need. PVA glues mostly specifically say that the joints need to be tight and well fitting, polyurethane glues expand and fill gaps but I don't see it being easy to use them to fill and smooth cracks. Would I be better off using a silicone sealant of some sort? The bricks are painted so the colour and texture of the result don't matter too much.
Any ideas would be most welcome.
