The builders that did my bathroom tiled into my bath so you get two good seals. They started tiling from a bit of stripwood after working out the layout and the hight of the bath so they only needed to do a single row of tiles with the bath in place. I was unsure about it but after seeing it for myself it made sense and you're not just relying on that single bead of silicone.
Today was tarting up the garden and protecting the back of the shed that gets hit with the most sun (lol) and rain. It was so dry I could go left to right three times without stopping to let it dry. I hate the colour but I never actually see that side.
I want to replace the decking but i've got enough on atm so we'll have to go with home bargains grey for now.
