The old non-skid on my deck was dangerously slippery and chalky. Painting with additive seemed difficult with mixed results, so I rolled the dice and bought knock-off brand EVA. I did a lot of ciphering and figured 3 sheets of 900mm x 2400mm size would barely cover the entire non-skid on my DSII. A few pieces would have the grain running sideways.
I wanted the brushed style for easier sweeping and found a great deal on Wayfair ($50/sheet). It came with some serious ripples in the backing leaving a few air gaps on the non 3M adhesive. No testing was done, and no installation until all was cut. I used a large roll of paper for templating—tracing the edge of my old non-skid with the side of a crayon. For the rails, I stuck remaining scrap pieces on first, then cut in place. Foam cutting advice came from this fun video: https://www.youtube.com/watch?v=E73AEz7t84E There is almost zero loss from cutting with the snap-off knife.
Placement was very easy by taping one end and the middle, slitting etc. Adhesion was no problem with only oxalic acid as deck prep. I used a hard rubber roller to work the glue but really had no bubbles. I feel like I could remove and re-place a piece if I needed to, yet I had no corners peeling after several months and outings.
I’m super happy with the results, both for cushioning and traction. Making a quick trip to the foredeck while underway is 20 times more relaxed than before. Water beads up like crazy but then evaporates that much faster. I didn’t get to test a heavy deck soaking, but I’ve hosed it off at home and it behaved as expected and dried in minutes.
The downside can be how dirt, dust, crumbs etc stay on the foam. I keep the boat fully covered with a 12’ x 20’ “polyester canvas” tarp at home. And my dirty crocs go in the well as I board. Problem solved. It’s easy to clean the foam but nice to avoid when you can. Trailering and sail camping are fine but I would want the boat covered other times.
And now that my boat looks spiffier, I guess it’s time to touch up my eyesore epoxy repairs. I bought some Tester’s enamel and will try to match it next spring.
