Melted Board

[mpbanskie]

Hi,

Just a short note of caution, we left one of our boards exposed to sunlight while we were out for two hours. On return the board had sagged very badly in the areas where the paint was darkest.

I won't name the brand as having had a search on surf board forums, I believe this would apply to all of our surf style construction boards on a warm enough day, be especially of boards with dark colours.

Regards

Duane.

You shouldn't be leaving the board out like that, if you do you should buy a board sock.

More information on where board was left in the sun? Was it on the boat? In the board rack?

I would hope a board is designed to sit in a board rack on the boat for the day without a sock on it.

I leave mine in the Bimini top all day while on the water. I have never had an issue, but I would love to know where yours was left out. I did have a issues with a board expanding on me, but that was because it had a chip out of it and I didn’t repair it. Water got in the board and it had about an 8” round bulge that was 1” tall. Learned the hard way and had to buy a new one. Thank goodness it was a old spare board.

Automotive interiors can reach 185F max in Death Valley. But realistic temps are maxed out at 165F even in Texas.

Interested in what resins are used on boards than melt below 165F

Most epoxy used in surfboard construction had a HDT (heat deflection temperature) of 120F + or -

Def do NOT leave them in the sun. Keep them in a bag/sock when not in use. In addition to heat UV will cause discoloration. Def do NOT leave them in a car.

Rule of thumb - if you wouldn’t leave your dog in the situation don’t leave your surfboard. - hahaha

Yep. Bought my first wake boat last year and the salesman sold me a decent $700 board to get started on. Left it in the board rack all day while on the water and the glue holding the carbon fiber shell let go, caused a huge bubble on the bottom of the board. At first they weren't going to warranty it but I convinced them if they don't they damn well should start putting a sticker on the board warning people against leaving in direct sunlight. I had no idea but do now. They gave me a new board and now I make sure that all my boards get used (water will keep them cool obviously) or stored in the shade for longer periods.

Board manufacturers need to use better epoxy, it’s not rocket science.

A board SHOULD survive in a board rack. I understand that some boards are made offshore and use questionable resins with probably very little quality control.

A surf board isn't designed to be stored in the rack, especially a custom one. They are made to surf and be light as possible. Cheaper boards are heavier and can stand up to being in a rack all day but suck surf wise. You don't have this issue with skim boards, at least not with phase 5, they're made like a tank but have less foam inside. Surf style boards are fragile.

[larry_arizona]

I admit I am new to boards and have MUCH to learn. I understand that being lighter is better, however, UV stable high temp resins should not add mass or rigidity.

Possibly a board maker could educate us on the reasons certain automotive grade (-40C to +85C) exterior epoxies are not used.

I appreciate the OP, I would never have known boards melt.

Thank You!!!

You are looking at it wrong - it’s not that surfboards aren’t for board racks it’s that board racks aren’t for surfboards.

Surf boards - real boards - are designed to maximize performance and to surf. They are not intended to go on board racks or Bimini tops on a boat. Board racks are a wakeboard thing not a surfboard thing. Round peg in a square hole.

Keep them in the shade or in the water - the boards will thank you.

[larry_arizona]

Thanks for that, hence why Supra has a surf locker.

Wake boards in board rack, surf boards in surf locker or a board bag.

Making sense now.

Where are you finding them for $30? The cheapest I have found is $38 on Wakemakers.

I found some surf socks for ocean boards that were of course too long, but a good deal on amazon. I used them with the too long end for a while, and eventually had my mom cut them down to length and sew them back together. The wife has one with a round tip that works great for her Doomswell Spark Plug, and mine has a pointy tip (like an ocean shortboard) that's great for my Doomswell Nubstep.

I would wonder how many of our boards would fit in the surf locker. I have a Doomswell Nubstep with the John John Grom fins and it's pretty thick all together. I'd think that maybe my board could fit, but certainly not 2 or 3 of them.

We'll regularly be out on our boat with mine and my wife's Doomswell surf boards (on the cargo bimini in board socks with bungees securing them on padded crossbars). Then we'll have 3 wakeboards, and two more compression molded surfboards (my kid's phase 5 scamp and a ronix caption "boat board" that all fit in wakeboard racks. We usually carry the wakefoil board, and that goes on the overhead board racks that I built, and we'll also throw my buddy's EPS foam core board up on the overhead rack also (because it's too thick and fragile for board racks).

Here's a good example of my need for board storage. Typical weekend day and we used all of these boards. (and my son wasn't with us, so his wakeboard and surfboard weren't on the boat that time).

But you can see the board socks on mine the the wife's boards. When we're trailering, we can fit the Ronix caption, adult wakeboard, and my friend's EPS surfboard in our playpen locker under the bow. My wakeboard and surfboard go in the Port locker (my son's surfboard can go in there too). The wife's Surfboard and my slalom ski ride in the starboard locker and we can put my son's wakeboard in there too if desired. The Foilboard goes on the floor when trailering. We can leave surfboards up on the overhead racks if we want when trailering--they have cambuckle straps and it's like having a surfboard on a roof rack of a car.

The surf locker would hold 1-2 medium length boards, it is length limited.

The Supra Bimini sleeves are nice with the attached cinch straps, skim boards will fit the ptm racks......just need to get some sleeves.

I can sew , so thanks for the ocean board sleeve idea.[emoji106]

I wouldn't be concerned with length, I'd be concerned with thickness with the big thruster fins on my surf style boards. (ya know, it's not always about length, it's thickness! THAT'S WHAT SHE SAID!!!). Mine and my wife's Doomswell boards are 4'6 and 4'4 respectively, so they're short but thicker. For us, the cargo bimini is really important. I've got my setup pretty dialed for storage, but I wouldn't complain if someone parked an SA in my driveway!!!

The skim board we have is compression molded. I don't see that one having any melting issues. Just our thicker EPS foam core surf style boards that get socks.

do a search on Amazon for "Surf board sock" and you'll get lots of hits on ones that you can chop down to size. :-D

[Shoebox]

Good call . . . thanks.That looks like the Ronix sock I have. It's nice but not very durable. It's almost like woven yarn, and gets holes easily.

[MJHSupra]

That foil makes the boat look like a spy plane. Pretty cool.

With all those boards, who needs a bimini?

[KnoxMojo]

I can fit 2 skim boards with fins in the SA locker, maybe my Doomswell Drone with no fins and one skim. 3 skims with no fins attached. I have surf socks, paid about $25 each on eBay. The mission are nice, but they aren't $30, the ones he posted are a different brand.

haha. you know that I REALLY just keep the foil up there to look cool while cruising around. It's all about the 'street cred'.

Exactly. We pretty much NEVER run the fabric on the bimini frame. (I modded the frame to have bungees that work w/o the cover)
In fact, the only time we really ever take the bimini cover out is if it starts raining! LOL

Oh, and you can't discount the use of the bimini frame for drying out wet life jackets and neoprene once we get back home!

Best to keep quality surf style boards in a board bag, this will thermally and impact protect it. Sock really only provide some amount of UV protection. Sock, actually get very hot in the sun. Many people get their boards wet and the sock damp to provide an evaporative cooler effect. The resins do not melt, but can soften, all epoxies can soften with heat. Epoxies used for surfboard are designed around flexural characteristics, modulus, viscosity, clarity, ease of use, etc. You aren't going to recreate the wheel here by trying to come up with a better resin. Air inside a foam core will expand with heat, this can cause pressure to build up which can result in many different things depending on the board build, age and condition. Maybe nothing, maybe water pushed out from a hole or ding, maybe a small bubble, maybe a big delamination. Warping or sagging can occur can also occur. Often people don't realize their board is warped. I see garage band builders all the time put out warped boards because they do not really understand the building process.

yeah, guess who was producing these first and whose been manufacturing board bags specifically for wakesurfboard for well over a decade.....

Vents are not new, vents have been going onto EPS cored surfboards since expanded and extruded polystyrene were first used as core material. We use to manufacture our own vent system that we sold to others. Vents go out of style and come back into style. Most custom board don't have vents because the core material is better or can be better quality.
General rule of thumb if the core material is less than 2lb pcf and the board is over 6' long you might consider a vent, also if the board is produced in china with potentially lower quality core material then a vent is a cheap safe guard. Might help, might not.

Hi,

OP Update - My first attempt to use the sun to reshape the board was not the best idea, the board has become very badly delaminated to the extent that last night I used a dremel to cut out a large section of glass - about the size of an LP if anyone remembers them. Under the glass, the foam is badly melted in a pattern that follows the black pattern of the paint scheme.

In addition to the delamination the glass itself is also warped, if it had not warped as badly I would have tried injecting resin under the glass to fill and rebind the glass/resin/foam.

My current plan is to learn what I can from the many surfboard repair videos online and have a go at filling and reglassing.

Will take some pics as I go in case anyone else finds themselves with a melted board and wants to learn from my repair/mistakes.

Soooooo, no black surfboards with foam cores if they plan to see direct sun for any extended period of time.

Go get some lightwight spackle and fill/cover over your melted foam. Once dry it will sand nice and easy. In the past these products were bright white, but many of the brands at big box stores have been colored grey to match normal spackle/mud, or have pink dyes that turn white. In your case since you will likely be painting it anyway you can use the grey stuff. Lightweight spackle is used by the industry to fill and smooth out rough foam, especially low quality EPS. Modern high quality EPS designed for surfboards does not require this step. This will seal your foam and allow you to get a finish suitable for re-glassing. You can hit us up and we can walk you through everything and even get a rebuild kit together to redo your board.

Cheers, Nick

I don't know how many guys suggested it...but surf sock your board when you are not riding it. If it's really hot and / or in a bimini surf pocket, put your board in the sock. Throw the whole thing in the water. A wet surf sock acts as A.C. for the board. Direct sun on hot days will warp surf boards. And they aren't cheap!

Quick update on the melted board as not many of us have taken a power tool to our boards, here is what I found expect first and unexpected second -

Expected
Its a polystyrene foam core, very similar to packing foam
There is a wood stringer with something like fibreglass tape over the top, I assume the tape is bonded and provides some additional rigidity rather than just cosmetic for reasons we will get to in a minute.
The polystyrene core is wrapped in at least two layers of fibreglass cloth on the bottom and at least one on the top

And now the unexpected -
Cosmetics - The paint is not paint, its a thin screen printed synthetic fabric which is sandwiched between two layers of glass on the bottom or the board
On the top the fabric is covered by resin without the layer of glass over it

Impact of the cosmetic layer - While tearing down the damaged area it was possible to score the top layer of fibreglass and pull large sections away this seemed to be a result of a poor bond between the synthetic fabric and lower layer of glass.

I have a video which I will upload if and when I find my go pro cable, in the meantime here are some picks of the current state of the repair, next step is to a new layer of glass on the prepped area.
