I have teak deck as well on my Ribquest: can only recommend; non slippery easy to maintain, nice to walk on with bare feet, and sexy?????? why does our ribs need to be sexy? I just want them to be fast and secure. the only disadvantage is that is weighs more than the traditonal non slip stuff. so make the rib a little bit slower I guess
Oh and it gets a bit darker after a while so getting that grey would become after a while darker!!!
