We live in the uk so wet winters fairly hot summers so I get that stuff moves but was surprised how much it has cracked

Hold up, Quad Max cracked?

Quad max has a lot of plasticizers in it. They will migrate out and the sealant becomes brittle. Also if you took it too thin the sun will destroy it

Maybe the product was bad. I live in US northeast, so we get a lot of expansion and contraction also. The point of the caulking is it’s supposed to be flexible. I think that you had a bad batch of caulking or something.

I used a few different types bought in different batches applied at different times - caulked the whole house! All were well reviewed on Amazon. Strange
