When my family and I were living on our first boat, a British built ketch in the Mediterranean, we visited many American boats and I always admired the way they used teak and holly or maple for their floors - or to use the correct nautical term, the sole. The shiny teak and white wood strips certainly enhances the interior of any boat, and it was one of the reasons I bought Britannia, which is American built with the same soles.

During all the time I have been working on all the alterations shown on this website I used the forward cabin as a workshop, and traipsed through the saloon with all manner of equipment and tools. I didn't remove my shoes every time either - it was just too much trouble, so the floors suffered and became scratched and dull. The white strips were hardly visible in places and the whole floor was crying out for attention. As the major modifications came to an end, I began to think how I might restore the floorboards. Whichever way I restored them a very important criteria for me was to ensure they finished up with a non slip surface. This was uppermost in my mind, because six months earlier I had slipped in the saloon and snapped both bones in my lower left leg, along with dislocating of the ankle. The injury was still giving me warnings about moving around on boats, so it was imperative I achieved a non slip surface.

                                                                                                PREPARATION:

The easiest sections to start working on were the twelve 3/4” inch thick plywood lift-up floorboards. The dirty ingrained varnish needed stripping from the thin veneer and like any wood restoration job preparation is the key. The more effort made at this early stage the better the final result.

Before I could even start cleaning the boards, I had to repair some of the damaged and missing sections of the strips and edging. I had kept some spare pieces of the original floor from the work I had already done, so I carefully scored both sides of the strip joint with a sharp knife, then using a newly sharpened 1/4” inch chisel I was able to actually ease the 3/8” inch strips out of their grooves. After cleaning out the damaged groove in the floorboard I glued a new strip in place and clamped it tight with a flat plate.

Many of the edging strips around the boards were also broken or missing, so I cut new 1/4” wide teak strips on my table saw and glued them along the edges. I also filled smaller indentations and chips with brown colored plastic wood.

The underside of the plywood must have been insulated at one time, but all that was now left was a dirty layer of dry adhesive that quickly clogged my belt sander. I had to use paint stripper and a wide chisel to scrape it off, then sand the plywood smooth. I also removed the brass lifting handles recessed into each board. Eventually all the boards were repaired and ready for sanding and cleaning.

At this point I give fair warning to anyone planning to work on their own veneered floorboards. Even when new the veneer is very thin, and if it has been worked on previously it might be extremely thin. Mine looked to be generally about 1 mm thick (3/64” inch), but thinner in places where it was scratched and dented.

I began sanding a board using a square orbital sander with 80 grit, but it hardly removed anything and would have taken an age to sand the hard varnish off. So I switched to my 3” inch belt sander with 100 grit. This removed more of the old varnish and grime, but it also highlighted areas that were slightly lower that the sander skimmed over. Attempting to sand down to these levels with a belt sander was a mistake, because I cut through the veneer in a few places, exposing the white plywood beneath.

There has hardly ever been a job I have done on any boat that has not created another job, or even two, and this project was no exception. It brought back the maxim every DIY boater should have tattooed up his arm, so he sees it before he starts a job. “If it ain't broke, it probably will be when I fix it!”

There was nothing I could do about this error until I started varnishing, so I continued sanding, but considerably more carefully. Belt sanding did not remove all the varnish or ingrained dark spots and scratches in the wood, so I pasted the boards with Goof Off Semi Paste Pro Stripper, then scraped if off with a 1” wide chisel. I scraped the dirt and varnish out of the deeper indentations with a sharp knife, then sanded them by hand to blend into the remainder. It was a slow but effective process. Eventually, after a week all the removable floorboards were repaired and sanded. A final preparation was to wash them with Teak cleaner, then scrub them with a stiff nylon brush. This still released an amazing amount of dirt and I did it twice on a few boards, but eventually they dried a clean bronze color with beautifully highlighted white strips.
,                                                                                                    VARNISHING:

Before starting to varnish I wanted to do something about the undercuts I had made with my belt sander, that had exposed the plywood. I had previously used a wood stain on plywood to make it look roughly the same as teak. It is called Golden Mahogany by Varathane. I carefully brushed this over the exposed areas and hoped for the best. I then replaced the brass lifting handles that my wife Kati had cleaned to a bright shine, and masked the edges. This was easier than trying to mask the actual recess without the handles in place. If varnish had run and dried in these cutouts it would need scraping out again, to allow the handles to fit back flush with the floorboard.

Normally the objective of varnishing on a boat is to achieve a high gloss finish, but it is invariably slippery, especially when wet. My concern was to finish up with a non-slip surface, so I asked everyone I could how this might best be achieved, and found different methods.

I called some of the major paint manufacturers and learned that two, Epifanes and Rustoleum, have a fine granular substance that when mixed in the final coat of varnish leaves a dimpled non skid surface. I also found an intriguing method on the Internet that advocated sprinkling salt on the final coat of wet varnish. Then, when the vanish was dry, hosing it off with water thus dissolving the salt and leaving an indented surface.

The easiest method that was suggested was simply not to sand the floorboards between coats of varnish. I especially liked this idea because hand-sanding twelve floorboards every time, between five coats of varnish, not to mention the large fixed floor areas, sounded like very hard work. I decided to use Epifanes clear gloss wood varnish, because their specification specifically mentions the varnish can be over coated within 72 hours “without the need for re-sanding.”

My first coat was a 50/50 mix of varnish and mineral spirits to make sure it soaked into the wood. I laid it on with a new medium hard brush always in the direction of the grain. I was pleased to see that even after the first coat the areas I stained blended quite well with the teak, and the strip repairs were almost invisible

I allowed the boards 24 hours to dry, then I had to remind myself not to sand the surface. Old habits die hard. The second coat was roughly a 75/25 varnish/thinners mix that brought out the color and beauty of the wood, already with a hint of a shine. By this time my garage was littered with floorboards resting on benches, boxes, and anything else I could find to keep them flat, and off the floor. After two more applications of 75/25 mix the boards gleamed. A final coat was neat varnish and I also gave the edges of the boards two coats.

Since I had not sanded between coats the surface remained quite coarse to the touch, but not enough to be felt with deck shoes or even bare feet. Upon testing a wet board it proved to be remarkably non-slip yet, it was also glossy. But there was still one final operation on the removable boards, the underneaths were still bare plywood, so I masked the edges and painted them white. It was a great relief to finally see all the shiny boards in place on the boat, but they also highlighted the horrid fixed sections of floor that I had not yet touched.

I then set about the back-aching, kneeling down job of sanding and cleaning the non removable sections. Some of these were also damaged and needed new strips splicing in. I stripped the old varnish off using a combination of belt sander and vibrating sander, to be able to get into the corners, but I still had to use paint stripper to remove the more stubborn spots. Then there were multiple coats of varnish to be applied, but thankfully no rubbing down in between.

It was harder work cleaning the fixed floorboards, but all the time I had the removable boards as an incentive. Eventually they all had a gleaming matching non-slip surface.

Even though I say it myself, the appearance is now spectacular! The cabin sole looks new, with a clean professional and safe finish. My predicament now, is I hardly dare walk on them!
