Thats a nice technique. Sand the tape line while the tape is still on. It keeps you from digging into the foam.

great vids,thanks. do you know how to do the peel off before set type deck grip to stop any need for wax.? my mal has this.

[@marccefalu9741]

Hey, me again lol! Sorry, but I'm doing an epoxy resin for the first time and your tip to sand the cutlap, use a few relief cuts and it'll peel right off....SPOT ON MY FRIEND! I used that for trimming the hull lamination on the deck and it worked out AWESOMELY! Question: will this work on trimming the deck lamination also? Not sure here cause the deck lam is bonding with the hull lam....and a little worried about sanding thru both the deck glass and also the hull glass...which wouldn't be good......

[@Shrednaught]

It’ll work both ways, you just need to be careful. Use an extra layer of tape ( so 2 layers ) and that’ll give you a nice high ridge line to sand and you should be all good.

[@shaharfunis8524]

great job !! can you explain more about the paint technic, is it pigment mixed with the epoxy? if so , how did it not mixes completely into 1 color?

Yeh it is just surfboard specific pigment and epoxy. There is a few tricks to not middle the colours together. If you watch the glassing part of the video I think I show them all. If not in this video then definitely in my other resin swirl vids 🤙

Awesome work....thank you Shrednaught for posting all these vids and being so diligent in replying and helping people out...quick question: do you use Additive F with the epoxy? Researching as I'm doing a board in the BioScience Epoxy resin and a lot of peeps recommend additive F....?

[@Shrednaught]

My pleasure 🤘 I’ve used the sanded.com version of additive F. It did help with the sanding coat. Less fisheyes/bubbles. Just check with bioscience epoxy whether additive F is compatible with their resin. I’ve never used their resin so I can’t comment on this.

Great video , built a few wing boards but want to start being a little artistic! When do you use the posca paint ? Just before the hot coat ?

[@Shrednaught]

I only use posca after the hot coat and prior to a final clear acrylic coat. I have heard of people using under hot coats but it can have a tendency to run if kicked hot.

[@6to6surf4]

does epoxy fumes smell as bad as Poly? thanks

[@jeffsauers17]

Great video. I have a question regarding the removal of the tape for the cutlap. There seems to be a bit of tear out when you pulled the tape up, do you go back and fill that? Otherwise would using some heat reduce that issue when pulling the tape?

[@Shrednaught]

Eps always seems to have that tear out. That’s the nature of eps. You can fill them if they’re quite bad but I didn’t. If they’re only around single bead size I just fill with resin whilst laminating. Heat does release the glue on tape better but it can also cause the eps to outgas with the temp change.

[@jeffsauers17]

@@Shrednaught thanks for the information! I didn’t think of the outgassing at all.

[@anon8730]

Never seen you do the polish step? What's the reason for that? I know it's time consuming but the finish is great

[@Shrednaught]

I don’t do polishing often. I do love the look but it’s hard to find the correct resin where I am.

[@robertcain3426]

I dont if its relavent to the new fin boxes, not the original FCS anyway, but in the old days with original style fin boxes we would put a 4 or 6 oz on the face of the box begore install which you can glass straight over. Youd do that by laying 4 or 6 oz cloth on a glass table, the fin slab table in those days, and laying the boxes face down on the laminate. Cut the exess glass off around the box and rough sand the face and insert them in the board and glass right over them. The last stage is after sanding or finish/gloss coat use a router with a guid st the bottpm the bit to cleanly rout out the box. Maybe you cant do it on the Futures if there is a screw im the side. Anyway i must be reminisci ng.

[@Shrednaught]

That sounds like a great idea. What were the fin boxes called you would use?

[@robertcain3426]

@@Shrednaught we only had one style of fin box in those days. I think theyre still around on single fin retro boards. The reason i used to do it was extra strength, not easy to year out the box with the laminate on top of it.

[@Shrednaught]

Thanks. I’m using keyline epoxy in this video. I would recommend.

[@6to6surf4]

Good tutuorial, was wondering if you use a tint or pigment with epoxy will it still discolour? like a clear epoxy will eventually go yellowish even if its not expose to UV. Cheers

[@Shrednaught]

I’m sure if you use a surfboard specific epoxy resin and tint it won’t dis-colour in a way you’re referring to. It may change colour tones eventually over time but I doubt it’d be significant enough to realise. 🤙

[@6to6surf4]

@@Shrednaught thanks mate!

[@JohnMiller-gl3ih]

Excellent work as always. Love the videos. Would like to know if you have a general rule as to how much resin to mix per side for lam and coats, etc.? I find that I usually mix too little or way too much resin. You seem to always have just enough to do the task and was curious what your formula was for determining that amount.

[@Shrednaught]

Thanks mate. For the lam I’ll be honest I mostly just make an educated guess. Depending on board length and amount of glass. I always aim for too much resin rather than too little. I’d rather have couple bucks left over rather than stuff a board. For the fill coat I always just use a plastic cup that holds 400-450ml and that seems to be perfect for all but the bigger boards. For an exact formula table I am pretty sure green light surf supply has one online you can use. Yew! 🤙

[@45surfboards]

Green light surf has a chart you can use and they give you all you need to know on your board length to resin ratio

[@douglassheeks8260]

Shred: Fantastic works of art. On your "Swirl" video, I believe you mentioned the board was ordered. Seriously, how do I place an order, including all the necessary details (design, size, colors, shipping to USA, etc.)? BTW, I do not do "Facebook." Is there another platform we may use to communicate, such as email? Many thanks.

[@Shrednaught]

Thanks mate. Unfortunately I don’t ship over seas as the price is just too outrageous. Best bet is to find a local shaper and have them reconstruct what you’re looking for. 🤙

[@dannyplayerorecinos6758]

Que buena técnica 😊

[@adamfiala7005]

Thanks so much for your videos! Do you seal the EPS foam before glassing? I’ve heard this is necessary for a resin tint but maybe not if it’s opaque?

[@Shrednaught]

Yeh if it wasn’t opaque you’d need to seal to get the consistent colour. Or a spray. With the clears or even this swirl I didn’t seal it as it’s so adhoc anyway that you can’t notice the slight change on colours.

[@nicd7718]

Thanks for posting those videos, they're very informative. Can I ask about taping the hard edge, like you say you want to make a little dam. What prevents the "dam" part of the tape from touching the glass and sticking to it when you brush your hot coat on? Especially going from side to side, doesn't the brush push it onto the rail?

[@Shrednaught]

I’m not entirely sure I’m on the same level but I’ll try answer anyway. The glass should be dry to the touch by now so the tape won’t stick to it. If you mean the resin over the tape and then hardening? That’s a possibility and if that happens you can sand away the tape when sanding the hard edge back in. The tape also doesn’t stick to the resin hard edge resin when it’s wet or to the gelled stage but it will be stuck if you let the resin fully cure. So always best to pull the tape when the resin is gelled and green but not full cure Hopefully I answered something there for ya mate 🤙

[@lock446]

Thanks for making these priceless videos! I'm about to glass a board with epoxy and wondering if you need to use any additives to make sanding resin? (I'm used to poly), or do you just sand the lam resin ?

[@Shrednaught]

Epoxy is able to be sanded without any additional additives. Although there are some that claim to make it easier to sand or help the fill coat with fish eyes etc:

[@beachmaster9042]

When you pull tape and foam beads off, what do you do? TY

[@Shrednaught]

You can fill with spack filler if you want. If they’re not huge I just fill when glassing.

hi mate what did you use for pin line?

[@Shrednaught]

Just posca pen

[@marccefalu9741]

Ok, last epoxy resin question...I swear! If you're doing resin pin line/s in epoxy how well do you have to sand the hotcoat? 80 grit, 120 grit....I am assuming the smoother the better, but maybe that's backwards...I'm such a newbie 😅

[@Shrednaught]

Good question. You need to leave enough grit in the resin for the pinline to hold too, but also don’t want the resin to bleed under the tape. I’d go with 120 and really push the tape down for the pinline

Do you have any tips on how to prevent the epoxy bleeding through when doing cutlaps? I am using the green 3M stuff, working on a clean board and pushing it down with a razor blade, but it still happens quite a lot. I heard it's harder due to the long hardening time of epoxy and its thinner consistency. But still, any ideas that might help? Loving your videos! Many thanks for all the amazing content :) Greetings from Germany

[@Shrednaught]

Epoxy is a harder medium to work with than poly. I’m going to assume you’re using eps? Try your best to get the foam as flat/flush and with as little bead tear as possible. It sounds like you’re doing everything correctly but like you have mentioned epoxy can be thinner and takes longer to cure/kick. Also as epoxy starts to catalyse it’s produces heat ( exotherm ) and this can effect the tapes glue. Try your best to remove as much resin from the glass ( as practical ) where the tape is on the laps to try and help. If all else fails just do a nice pinline to hide the bleed through. Thanks for watching, appreciate it 🤙

[@Rebecca-it8ll]

@@Shrednaught I am using XPS, but I guess the same applies here with the bead tear. Many thanks for the detailed reply. Best shaping channel out there in my opinion!

[@Shrednaught]

Yew! Thanks. Any further help just hit me up 🤙

[@ichorousmedia]

With epoxy, even with the good tape, does it leave residue or have any bleed through after having to wait so long for curing? I also noticed when you pulled up the tape it seems like it ripped out some foam on the deck too. I doubt you encounter any of these problems with poly...

[@Shrednaught]

Yeh it can. But there is ways around it. You’re correct, my tape did pull some small beads up. I could of used a hair dryer/ heat gun lightly to warm the tape glue up. The thing with eps is that it’s so light you can fill these small voids with resin and it’s unnoticed. They then add a tether point into the foam IMO Both eps/epoxy and poly/pu have their pros and cons and using either can be decided when thinking about the application ( wave ) wanted to be surfed. Cheers for watching 🤙

[@ichorousmedia]

@@Shrednaught thanks for the reply! I have yet to glass a board with epoxy and have limited experience using them in the water as most of my boards aren't very light.

Yeh the dark colours you want to use less of. So with swirls if you’re using a colour set you also need to think of what colours they’ll make if combined. Green and orange make brown. So use colours in the same palette and you’ll generally get what you’re after. Darker colours always over power

What fin box system do you prefer? FCS II or Futures?

[@Shrednaught]

For my personal boards I have mostly glass ons. I initially did go with fcs2 as I could determine the cant for the specific board. But I do like futures as they have a larger selection of fins. For the most part I use whatever the customer wants.

[@Carkshark]

I ask because I've lost fins with the FCS II system when I didn't use screws. Now that I use screws, I think it defeats the whole purpose of the system and the tight fit has caused me problems with cracks around the boxes when inserting or removing fins enough times. Do you think futures will give me better luck with less board repair? I only have one set of FCS II fins, so I don't have a lot money put into that system yet.

[@Shrednaught]

@@Carkshark yeh same. I’ve also lost fins. So now I always use a screw in the front. That way I won’t loose the fin but it’ll still pop out if it’s hit hard and not take the fin box out with it. Im not sure about the tight fit? Are you using genuine fcs2 or an aftermarket fin? Maybe a light sand on the fin tab will help.

[@Carkshark]

@@Shrednaught Started with a set of FCS II Medium performers in "Glass Flex" (plastic). I tried the single screw trick after the first time I lost the right fin, but a week and a half's worth of surfing later the damn right fin came out again. Each time I had one come out I recall turning right really sharp before dismounting. So, now I use two screws for all the fins. Didn't have any more fins come out so I got rid of those plastic medium fins and bought a set of FCS II Mick Fanning Large fins. Great fins, just don't like taking them out and messing up the glass around the boxes on my polyurethane board. By tight fit, I'm talking about the force needed to pop the fins in or out against the tab in the back half of the box.

[@Shrednaught]

@@Carkshark ah yeh I see. I guess grub screws are the only thing to prevent that. For popping the fins out I bought this leverage tool called “ fins out”. It works amazing and was only about 15 bucks. You should check it out 🤙

[@mikenuke]

oh my , i see 2:05, this little bastard tape, is taking of grains of the eps...how do you deal with this...please answer, you made such a perfect job shaping a baby butt surface and this ruins all your effort. what is the density of the foam you use.and how do you deal with this situation after it happens, do you glass bubble filling it again?

[@Shrednaught]

Unfortunately this is the norm for eps. The construction of the foam beads just allows easier tear out. You can sometimes mitigate it using a hair dryer or similar to warm the glue on the tape but in all honesty it looks worse than it is. It’s a very high density foam. If the tear out was significant I’d use a spack or a qcell mix but for this board I just glass as usual and fill with resin. The weight on eps is light enough that doing this doesn’t make the board feel too heavy. Cheers 🤙

[@mikenuke]

I use eps 200 and I have no problem of this kind.

[@Shrednaught]

No bead tear using the same method of allowing the epoxy resin to fully cure then sanding back the tape line? That’s rad eps if so. 🤘
