Thanks all. I've had a look at the bucket glove. At the moment it's only available in a 300mm diameter by 300mm high bucket which is not even big enough to fit a tiling trowel into to be honest.
Those ones are around £20 each and you would need 3 realistically. I think the larger ones that are supposed to be coming out soon are for their own 30L buckets and you could imagine them being around £35 each.
I'm not convinced they would work with flexible
tile adhesive either. Certainly my attempts to knock flexible
tile adhesives off a flexible bucket don't work very well!
Guys, those of you who said you might be interested if the product ever did come to market,
I would be really interested to know what price you would be willing to pay for a pack of 10 liners. They would be made out of 2mm thick plastic and definitely stand up to a mixer paddle knocking them around, based on the prototype ones we've tried already.
I'm also going to investigate whether it's possible to make it so that the plastic liner can be reversed inside out and used a 2nd time too.
