10 years going in full sun - still look great.
By Dutch Sailor from Asheville NC

This product was installed on the entire deck of a 44 ft offshore blue water sailboat. This boat is an all aluminum cutter. While I agree that this diamond texture pattern is a bit hard on tender feet, one can get quite used to it. On this boat, the sand color was installed, glued down with epoxy. As it is rubber (and not plastic), sunlight seems to have little, if any, deteriorating effect on it. It is easy to keep in good shape with a periodic pressure wash. We sailed the entire Caribbean for 5 years - the boat has been in full sun for about 10 years.

Bottom Line Yes, I would recommend to a friend

I will buy this product again.

Verified Purchase

I used Treadmaster to cover a repaired liferaft compartment top in the cockpit sole. It looks good and added strength to a surface that gets jumped on.

sand white Treadmaster is great
By blue sky on st john from st john US Virgin islands

We have a yawl that lives year-round in the Caribbean. Parts of our deck have the sand white treadmaster, (the rest is sand-painted). We moved to the Caribbean from NY 19 years ago -- and some of the treadmaster was installed in the late 1980s and some in the early 90s. So it has survived New York winters and 19 years in the St. John sun. It is still perfect - edges a little more rounded. Still very safe. I was surprised to see someone saying it didn't hold up to UV. In our experience it does. Don't know if the other person was using another color or if the product's manufacturing has changed. We also NEVER use detergents or chemical cleaners -- and that could reduce the life of the treadmaster. We are about to buy some more. It is for safe offshore use - bare feet fine - but would NOT have it everywhere. Don't want to stand on it prolonged in bare feet.

Bottom Line Yes, I would recommend to a friend

Good use for Treadmaster
By Jim in Huron from Huron, Ohio

Was looking for a material for step treads on cabin entry stairs. Old "coin" material was dated and not that non-slip on my 33" Tiara. Resurfaced the stairs with this material, edged the steps with teak. Looks great, excellent non slip. Full varnished teak steps can be slippery when wet. Cuts easily, installed with epoxy resin. Previous reviews were negative on outside use. This should hold up well in the cabin. Can recommend this product for this use. Only drawback is the size of roll, enough for about 6 steps, and pricey.

Bottom Line Yes, I would recommend to a friend

Treadmaster several cons few pros
By sailse from south florida

I spend loads of money/time to install it. They claim it lasts 30 years (maybe some pieces of it" but it will looks so bad after 10 you will spend the high cost to remove it. This should never be used on anything but off-short commercial/racing vessels. It is too ruff for the ladies to lay on in their bathing suite even with a towel. You will tear up your feet if you try to go bear foot even while at anckor. You will get constant complaint from your friends and you may even have to pay for some damaged designed swimming attire.

Treadmaster lasts 26 years
By joper from New Bern, NC

In 2002 bought a 1980 Dutch motorsailer with Treadmaster factory installed. It covers the entire deck. For the most part it has held up well. As of late some of the sheets need replacing. While not cheap, it does its job well. The traction is superb in very wet conditions. I intend to replace the sheets on a as needed basis and recommend it highly.

Bottom Line Yes, I would recommend to a friend

unhappy with treadmaster durability
By Captain bob from Palm Coast Florida

I resurfased theentire deck of a 55' ketch approx. 11 years ago with Awlgrip and Treadmaster. Disappointed in the way the Treadmaster has just disintegrated over the years. I must now strip the entire deck and redo the entire thing all over again. Will use additive in the paint this time. Treadmaster looked terrific when completed but did not survive the exposure to UV

Bottom Line No, I would not recommend to a friend
