My husband works for a canadian distributor of azeck and timbertech (he manages that product) We are starting our deck this weekend. So far, my experience with the samples we have at home (weathered teak, and english walnut) is it doesnt get that hot. The darker colours will, but so does a wood deck stained dark. English walnut is a medium brown and Im surprised that it doesnt get that hot, and if you have wet feet it feels less hot. We are still planning on doing mostly weathered teak with a boarder of English walnut. What sold me is you wont get splinters from being barefoot on the deck. My daughter gets crazy splinters at my parents cottage no matter how diligent we are replacing dock boards. We have a small platform built from the english walnut we are using while our deck gets built and I havent found it slippery at all. My husband said its not supposed to be, but like any wet surface you can still slip ?

he said its a very common misconception with the product.
As said above, sunscreen with stain, and I think my husband said bug spray does too, so you have to be careful about applying those.
Its expensive, but I think the benefits are worth it. Im looking forward to not having to replace it!
