Over Zealous Sanding

Here´s my first ever creation based entirely on Swaylockian advice. It´s been a complete solo flight so far but I´ve now reached a stage where I need some guidance.

I´m working on a 5.9 quad. Everything had gone pretty smoothly until I had my first run in with Epoxy. I´d never had any contact with laminating anything before and was caught out by my inexperience. My batch of epoxy started to kick really quick the day I did the bottom lam. In my inexperience (and slight panic as the epoxy started to get alarmingly hot in the container) I ended up with some pretty hefty excess lumps of dried resin, which I then attacked with the sander. As you cans see from the photo this has left me with some serious marking.

My question is how can I keep my project from going off the rails, aesthetically speaking? I had thought about painting the worst areas? Hot coating with pigmented resin? Setting down another laayer of glass? I´m really not sure what would be best.

I’d get it as flat as possible and then give it a thin gloss coat of epoxy.

Tape the rails so that the resin can flow off without dripping onto the lower side…

Let that set and repeat on the other side…

You can tint/colour epoxy so that it covers a multitude of sins…

Mix smaller amounts, you’d probably use about 120ml for each side…

Ask Chip, he did it on the Bushfire Fish…

Good job so far…

After looking at your umm, ordeal, I’d say sand the glass until it is almost all gone.

Then, re-glass. (consider this your penance, or punishment, ha.)

One other thing, the weather is pretty warm in most of Brazil, so epoxy will kick faster.

The epoxy in your bucket will kick even faster than on the board. So my advice is to

ALWAYS pour the entire contents of the bucket onto the board and spread it out. It

will stay wet almost twice as long.

Depending upon the brand of epoxy, you should have about 20 minutes of working time.

This is very sensitive to room temperature. Best is around 80 to 82F At 85F you will

start to see instability. I suggest you do your first glassing early in the morning and

as the temperature goes up, your board will harden.

Good Luck.

Thanks for the advice guys. I´ve learnt my lesson with pouring on all the resin. The deck came out much better. Hicksy by tinting my gloss coat do you think I´ll be able to cover up most of thos scratches?

If these are just scratches, they shouldn’t show after hotcoating on them. Just sand everything nicely and hotcoat. It should come out nice.

You know,I have made perfect boards that didn’t ride so perfect…they rode ,but not to my standards,completely !

…some of the hacks I’ve built have been some of the best riding boards…EVER !!!

Just to give you guys some feedback. I hotcoated the board the way she was with some pigment mixed in and it turned out quite well, for a newbie anyway.

All the scrathches have diappeared! Hurrah!

Then I did the worst pinline ever! And a pretty shocking leash loop too.

Hotcoated the deck…

Managed to go over the fins with some resin! Hopefully that will sand off. So just got some serious sanding and polishing to go now and number 1 is done. I´ve learned a lot through trial and error and it´s been a really steep learning curve but a lot of fun too. Thanks swaylocks for providing the initial stimulus. I owe you a beer.
