Inspired by my fellow 310 Captains, i just completed the Plasteak version. The teak & holly Matte matches the our sole perfectly. OK, removal! The Admiral suggested using a hair dryer to loosen up the old treads; like all of her suggestions worked great. Heat up an edge and start peeling. They came right up. then used goof-off for cleanup, especially around the edges which are dirty and may be seen after the new tread goes down. The treads stayed together and could be used as templates. But sticky everywhere. Make sure you cover up everything and wear disposable gloves for removal and install.
Bought vinyl adhesive from Plasteak, and needed about a pint. probably could use any vinyl adhesive from the flooring or hardware store. After cutting the new tread, with the lines matching the lines on the cabin sole, you use a 1/8 trowel to apply the adhesive. Don't use too much, as it will continue to trickle out for several days after install if too thick. Tip for lining up the lines is to start with the bottom step, and keeping matching each stair with the one below. Ya, ya, I messes up the 2 nd step which got canted a bit. Guess what, you cannot get these up after they are set for 48 hours. So I have to live with the off centered one. A small roller would help to seal it down, but a rag in hand seemed to work.
The Plasteak people , Sarah, were very helpful and confirmed that I needed 2 linear feet if I wanted to match the lines. With material and shipping $125. Love the look! Thank you for the inspiration.
