New Non-Skid for the Companionway Stairs


The companionway stairs have an inset for Treadmaster SP which I removed prior to varnishing the companionway stairs. I ordered a single sheet of teak colored Treadmaster SP to replace the original material with. There is just enough material in one sheet to replace all of the companionway treads twice. The original installation was obviously designed to allow for easy replacement over the years. Thank you again Oyster for building a boat with a mind toward long term maintenance!

I used a straight edge and a single edged razor blade to cut the pieces to fit. Note that each of the treads is just enough different to require a custom cut to look proper. The project took most of a day to complete and then an additional few hours to polish the brass rub strakes which go over the intersection between the teak and the non-skid material.

I used "Weldwood" contact cement and each tread required approximately one small bottle. In California real contact cement is only available in small containers at a cost of about $5/bottle but at least it is still available. The issue is the volatiles which are very carefully controlled in southern California.

The result is beautiful!


When cutting the pieces I made sure there was a very good straight edge on the front and that the piece was a bit snug across and then was trimmed to fit. The contact cement took out the snuggness making for a perfect fit.

The DeWalt 18V portable vacuum with HEPA filter has been a godsend!

Cutting Treadmaster SP is very easy, a very sharp razor blade works very easily although it is important to keep the cut straight up and down. to get a nice clean edge. I leave the back of the step with too much material and trim to fit after the contact cement has completely cured.

The forward edges of the stairs have a bit of a turn out which requires some careful trimming. It may be that there is supposed to be a bit of teak which fills in those spots but now it is just being filled in with the non-skid material.

Careful trimming with a straight edge is important!

All of the pieces are now cut!

The blue tape is in two layers, the lower marks the beginning of the brass strakes so I can find the screw holes again. Over that one extra bit of tape is applied to help with getting the contact cement applied without getting it all over the varnished teak

Everything is finished except for gluing down the bottom piece. It turns out that the strakes on the three steps are are even because the Treadmaster SP is just the right thickness to make it flush. The bottom tread has the treadmaster on top of the cover for the generator and so it stands up by the thickness of the treadmaster SP. With the overlap the metal strake does not look right as it is angled so I have cut the piece of non-skid so it is completely under the brass strake and then is cut back to look like the upper treads.
