Kiwi Grip nonskid paint has really impressed me. Almost a year in the tropics and it has retained its color and its non-skid properties and its holding up very well. Being a one coat - one step product I give it high marks for ease of application and durability.
Their special roller produces a nice texture but does throw little threads of paint when rolling out the product, even when I rolled it fairly slowly. The solution was simple; ensure that you mask adjacent areas very well. We used a paper and tape dispenser and papered at least three feet from where we were rolling out the product and that solved the problem.
I wrote about the application process in previous posts. Here is the link for those interested.
