I'm doing a shaker style kitchen (sort of!) in our new house build and we'll probably go a powdercoated white splashback. I'm totally in love with the whole look though and I also want to use it in our entrance ceiling and also a feature panel on the exterior of the house (might be too much to do all 3 I think hahaha)!
I saw an absolutely amazing example of it used on the exterior (I think it's your website) and am really inspired. Should it be powdercoated for exterior use also??
