Diamond EVA Foam Sheet - Dark Gray/Black

I love this on my boat, dropped my sundeck weight down by 40lb when wet an 20 when dry. This stuff sticks to everything, easy to clean, looks great, soft to walk on yet still have traction and cool to walk on in 120deg heat index. After putting on the back deck I replaced all of my floor with it

I tested this for a year on my companionway stairs, with daily ins and outs, and it stood up with no noticeable wear and tear and the glue sticks really well. Then I put it in the cockpit and really like standing on it for long periods of time while at the wheel.
So I went for it to replace my aging non-skid portions of the entire deck.
It's traction is better than sandy non-skid, easier on your feet, and rear end when sitting up there, etc. Insulates a bit too which is nice in Kona Hawaii where sun everyday is the issue.
The slight negative is that the width is not cut exactly on the strip of "wood" edge and you have to sacrifice a strip often enough.
This is not a negative but the layout can eat up a lot of material in order to keep the pattern looking correct....but that's normal on a boat. Just be aware that you will need more than 30% plus probably. You'll get better coverage with the diamond pattern with typical sailboat layouts. but not much better as it turns out. I sanded a bevel on all the cut edges before sticking down - much easier than after.

Initial impression is that I am really happy with this product. As you might expect, it's a bargain compared to a professional installation. Admittedly, the custom jobs are going to be nicer but in my case it wasn't worth paying 6x the price for something I wanted to try anyway. The color and texture has been very consistent over several purchases so there have been no issues matching sections. Ignore the water spots in the first two pictures. The foam cuts easily either with a utility knife or a pair of scissors. Application is easy and the adhesive is very sticky. Once applied is is very comfortable to walk on and makes a big difference in the comfort of your deck, particularly if you are barefoot.

Some suggestions for applying: Let the sheet age and relax for a few days prior to using preferably in the sun where it can get hot. The foam will shrink a very small amount so you want that shrink out before you cut and apply. Also, a roller is a must. It was obvious that even after pressing and walking on it, rolling the foam still found areas that did not have good adhesion. Last thing to mention is more of a personal preference. I would suggest making templates and cutting sections as opposed to trying to cut this in place. It's a little more work but you will be happier with the final result. You can find examples on-line.
