Two Hotcoats?


I’m currently working on my first board, it’s a 7’6" egg. It’s been an eye opener!

Anyway, I did the lam and my laps were a bit rough, I sanded them down (but I now realise I didn’t sand enough, it should’ve been very flat). I’ve done a 6oz bottom and 2x 6oz top.

So I did the hot coat with a few bumps round the laps and then sanded it all flat. However on some of the laps I sanded into the weave to get it completely flat (not alot, maybe in about 5 places around the laps, each an inch or so in length). Anyway, I was going to gloss but figured that because I’d hit the weave in a few places that I’d do another hotcoat and then sand this to finish instead. I’ve already done the second hot coat but there’s a couple of things that are worrying me.

  1. Is a second hot coat any use in this situation? Have I just added more weight to the board for no benefit?

  2. Will the second hot coat bond to the first hot coat properly? I did sand it all but it was quite smooth.

  3. Should I sand the second hot coat quite hard as it feels like I’ve added a fair bit of weight to the board? I used 450ml of resin for each side on the second hotcoat.

  4. Is it worth doing the gloss coat?

Many thanks for any advice.

Hi Thurso, you Scotish by any chance.

Don’t worry about hitting the weave on the laps, perfectly normal when your starting out, even most pros will his a bit of weave now and again.

You need to sand heavy if your hot coat is thick to reduce wieght, if you hit weave anywhere else. especially the rails dont sand any further in that area, just concerntrate on getting it all smooth, if you have any small shiny spots go back and hand sand those areas.

Any exposed weave will disapear with a gloss coat, you can still only go as far as a sanded finish or go further through the grits, compound, wax and buff to a shine.

Hi Woody,

Many thanks for the response. Yes, I live in thurso.

I’ll sand down the hotcoat tonight, the board is actually for my brother in law who’s learning to surf. Do you have any idea of what

sort of weight the finished board should be? I only ride shorter boards myself and this has alot more volume, just worried I’ve been a bit overzealous with the resin.

Cheers again.

Hey Thurso,

I’m just a garage hack like many. If I plan on a gloss coat I sand the hotcoat pretty heavy knowing the gloss will make a few weave areas disappear and then am very careful around the rail areas when I sand. A bit of weight is a good thing in a beginner board I think because once the board is up to paddle speed it will maintain it’s speed a bit longer than a light board for that all too important transition from prone to up on the feet. Same is also true as you get a bit older and slower. Know what I mean? Mike

Hi Mike,

thanks for comment, I was at work when asked question so was working from memory and comparing weight to the feel of my other boards. I got home tonight and measured weight of board at 5.9Kg, I then weighed my biggest board (7’2" rounded pin) which weighed in at 4.8Kg, given the extra volume and the size of the egg I think this is in proportion. I was just worried that I’d gone a bit too liberal with the hotcoat.

thanks again for input,


If you’ve hotcoated the board a second time and you’re worried about weight just keep sanding with your sander set as low as possible. Take your time and you should be fine. In the future, if you expose any weave just hotcoat those areas and hand sand. It’s pretty simple. I’ve hotcoated twice before as well. Never had any problems with doing this, just make sure you cut the wax off the surface.
