I agree, i spent all day trying to find a decent stamp project that didnt look like a driveway in a Florida housing project. what about flagstone?It gets really hot as i remember from my youth in colorado. The thing is , I have a rusty roof,a barnwood grey siding, and i thought i would go with something with a little oxide to tie in with the roof and contrast the grey.Its in a rural area, Twisp WA. so I cant go too fancy. Origionally I was builing a french country house but it has taken on a little western feel. I'm afraid square pavers would be too estate like though i love travertine . Hence the limestone that can have dark oxides in it but it s really expensive to ship. what about just a colored cement like an acid wash. half the deck is uncovered so if it got wet it cant be too smooth.
