Misleading details
Got produce expecting it to be rubber both sides…it was gravel on top. Never did any good with gravel for valleys on roofs before, so tried to return it. They wanted me to pay for shipping which was anywhere between $60 to $100. They indicated if it was over $30 to contact them, not satisfied with even having to pay anything for the return…dissatisfied customer…

From roofs to ramps
For years we have been looking for a solution on our properties handicap ramps and how slippy they are. We added a layer of this and it has worked wonders for us. As this isnât a traditional use of the product it was nice to use it for something so beneficial to the handicapped members of our family!
