Deck planking and gap

Post by Tony Hain »

Building a Tahoe 23. Wondering what approximate width of deck planking and gap between the planking people used.

I use 1/4". You can buy plastic spacers for tile at he box store for very little.

I used 1/4 on my barrel back. I used slightly thicker deck boards ~1/4-5/16 than standard. Wondering if the thicker caulking (3M 3000uv) will be an issue? Another question is whether varnish needs to be removed from gaps? I’ve not purposefully put varnish in the gaps but hard to keep it out when brushing...and wonder why I would remove it?

I filled the gaps with epoxy and varnish.

I went with 3/16. GarWood ran that on theirs. What you often see are deck seams that have been reamed out over the years of recaulking so you can do that too. Probably easier wider if you are using contrasting wood stripes
Wish to correct myself on this one and add a vote for Jim’s 1/8” width for the seams. :)

Classic boats had 1/8 caulk lines. See page 12 of my build. I coated the grooves with varnish before applying the caulk. Boat life caulk was great. Link below. Scroll down on page 12.

Thanks Jim. I read somewhere (Classic Boat Connection?) that boat life caulk shoukd not be used for thicknesses greater than 1/8. I have 1/4 width and depth and have been thinking of going with 3M 3000 uv. I'm not planning to varnish over it and paint as you have done (looks fantastic). I do wish I'd gone with narrower gaps. As you can see...that ship has sailed.

Thanks everyone for your comments. So it looks like I am aiming for a gap between 1/4" and 1/8". It will depend on the width of the planking. I think I've read people working on around two and a 1/4 to 1/2 inches. Any comment on planking width would be appreciated.

I haven't decided which way to go on the caulking yet. Have finished the cover boards and king board and will post pictures on my build post soon. I am at that point where I have to decide on the deck colour etc.

I misspoke earlier. I did not fill the gaps. I did epoxy and varnish before filling with caulk. My deck planks are 1 7/8". That is the same as the width of the masking tape.

Thanks Bill. That’s how I interpreted...

My deck planks, in the picture, are about 2” wide. I measured and calculated but still made slight adjustments in the widths of the last several boards to help me get a wider board at the edge. I can’t tell they are thinner by eye. Bill’s idea of 1 7/8 would make taping a lot easier.

Yes, matching board width to available masking tape size makes a lot of sense if possible. So plank width probably more like 2" than 2 1/4".
