With some kits from Petite Properties on the bench, I asked them which glue they recommended. A bottle of 502 adhesive was waved at me - apparently, it's the only PVA in the workshop.
I knew I'd seen the stuff somewhere and a quick web search took me to Tool Station where it's a fiver for a litre. Fair enough, when I was passing I picked some up.
The dolls house makers are right. To date, I've been a Resin W man, or a big tub from Homebase depending on the job in hand. This stuff flows a bit better than Resin W but not as a freely as the cheap stuff. It grabs quickly and dries as fast as any.
Decanted into a Metcalfe Models Ultra Fine Tip applicator, it's very easy to use too. Even from the big bottle, it's controllable and the nozzle of this doesn't seem to gum up as fast as the resin W version.
The frames of Polar Bear were laminated up and seem to have stuck. I'm sure someone will say all PVA's are the same, or that they have used this stuff for 100 years, but I'm impressed, which is why I put it on here.
