Hi guys

Bought a used 14x23" WOW Muon yesterday. Used then and also this morning. Following ins and outs in choppy conditions this morning I realised one of the screws for the carry handle was loose. Removed the screw and noticed the screw was straight into the carbon, no screw mount. After checking pics online noticed that the board does not actually come with a handle and someone has installed one on the rail by screwing straight into the carbon.

Was able to suck water out of both holes and after leaving in the sun for 5 mins further water came out and could also hear the fizzle sound.

Would be great if people might recommend best course of action. I was planning on leaving the board to dry for a couple of weeks before filling the holes with 24hr epoxy resin, possibly with some talcum powder mixed in.

Have also noticed some small blistering close to one of the holes and on the underside of the board. Is this a major issue or can I forget about it?

Have attached pics.

Just a note that I think the Muon is great. Very stable for 23", cuts through chop well and picks up bumps nicely. Haven't actually used it in flat conditions yet. Hope it glides well :)

Thanks in advance for any tips/recommendations.

Jon

I would weigh it and see if you can find an accurate weight to compare it to. Do you have any idea how long it had been since it was last used before you bought it?

Weighed when I got back from the water and it was 13kg. Website says approx. 12.0kg. Will weigh again in a weeks time.

Website weights are not very reliable, the actual weights can differ a lot.

The best methods to see if there is water in the board are:

- make a small basin around the hole with tape, and put soapy water on the hole and the board in the sun, for 2mn max. If you see bubbles, there is a leak

- take a paper towel, twist a corner into a wick that you insert in the hole. If it comes out wet after 30mn, there is already water in the board

Hey Colas

Thanks for taking the time to reply. I know that water did get into the board. I was able to suck a small amount out when I got home yesterday. I tried again this morning and couldn't suck any water, so hopefully it wasn't too much.

just wondering about best course of action. I'll try the paper towel trick.

Do you think a couple of weeks to dry before putting epoxy in the holes would be okay, or is a board screwed once water gets in?

Is the blistering related to the water getting in?

There will be damaged water logged foam around the holes regardless of how much drying out is done.
Your course of action suggested is ok & what 90% of people do to their boards.
If you love the board & want to keep it forever then grind around the hole and dig until you find dry foam, replace the foam with new stuff then glass/carbon over the top.
Cheers

Thanks so much for all of the replies.

So the EPS foam (I assume it's EPS?) inside the holes doesn't look too bad, pretty white actually, albeit there was water in there so there has to be damaged foam.

I plan to fill the holes with a polyurethane expanding foam, as per the boardlady's recommendation...

Only thing is, you can only buy the 2 part marine stuff in large quantities at higher cost. I was thinking of using Sika Boom Expanding Foam, from Bunnings, however I'm not sure that this would be different to 'marine' grade??? The product description says it is a polyurethane base. Would anyone know whether this would be a good substitute to purchasing the 2 part marine stuff?

Ill let the expanding foam fill the hole, then cut out maybe 2mm below the level of the carbon, then apply epoxy mixed with talcum powder and tape over that while it sets, before wet sanding it smooth.

At least that's the plan. Would be interested to hear anyone's thoughts.

Don't bother with PU foam. just take any packing EPS foam, detach the small balls of foam and fill the hole with them.

Once you put epoxy resin + microspheres in it, it will re-create a super strong and light "foam".

Thanks Colas. I'll go with that.
