Great video .....watching your videos has given me more confidence....now I'm going to restore my old boat from when I was fresh out of high school....a 1975 glastron cv16.....complete restoration in and out .....thanks for explaining so much of the different ways to do things
hi Andy! I'm a first time commenter but long time lurker. I'm finally pulling the trigger on a Sumner dinghy restoration, and this video couldn't have come at a better time. I'm upping my order to the 5 qt tub to go with my B size 5:1 Total Boat epoxy. Thanks again for all of your GREAT informative and entertaining videos! I also started a youtube channel (Scientist Sails), but it'll be a long time if ever before I come close to your great quality work. Cheers!
I support your use of the scale as it gives consistency! I mix small batches on the scale, both epoxy and polyester resin, to get consistent results. The Superbond epoxy comes premixed and never runs. But I still use the scale to get a consistent mix one to one. The Superbond is a 2 gallon (a gallon of thickened resin and a gallon of catalyst, 1:1) for about $200.
Very useful Andy 👌 all makes sense. Iam using poly for my project due to costs , and mix ath powder into resin to make up a filler, can vary the amount for consistency but mainly use a mayo to peanut consistency. The consistency for using on wood makes perfect sense as the wood will soak up a fair amount of that moisture from the mix.
Got it - 1.0, 1.5 and 2.0 as a going in ratio (based on temp, resin type).. Then 1 Tub, 2 Tubs and 3 per TB epoxy kit. I like the 2 Tub recommendation per kit too!! Thank you!!
Thanks so much for this! I'm using epoxy for the first time, and I've been wondering how much silica I would need for making fillets. Now I know, really appreciate it.
Hello Andy! First thank you for sharing your knowledge! I was in the middle of a restoration project (67 fiberform). When I ran across your site! All though, a boat builder by trade, your onsite help immensely!! Amazing how just simple formula's get complex if not used " in a while" Battling the dreaded "C" word (Cancer), but with the excellent care I'm receiving in Mexico, I hope to reopen my lifelong dream of bringing the classics back to life in Eastern Washington. It wouldn't have happened without your positive show! Make it a great day!
Andy, I've been redoing the transom on my 1984 Grady White 24 foot project boat. I know you're a Totalboat product fan. I've been using FGCI Superbond epoxy to glue the Coosa board to the existing transom. It doesn't run and has a long working time...just mix it and stick it. For the edges where the Coosa meets the hull I use Totalboat Structural Filler. This time of year in Florida it gets cool at night. If I catalyze at 1% it takes two days to cure, need to do 2% close to 60 degrees. It mixes easily and goes into the gaps with a nice smooth finish. I just need to add the fillets where the 1708 fabric will attach the transom to the hull.
Great information Andy, that gives ma a good base to start with. Gota luv those mixed imperial/metric measurements.😂😂 For us who have no idea about imperial measurements. i did some conversions Ketchup = 1lt base, 500ml hardener, 92 grams of silica Mayonaise= 1lt base, 500ml hardener, 125 grams of silica Peanut butter = 1lt base, 500ml hardener, 185 grams of silica. Awesome ptactical knowledge video. Cheers.
I love the breakdown that you do here, Andy. Thanks so much for that! I would have loved it a biiiiiit more if my kit from Jamestown hadn't just been delivered with only one gallon of glass balloons. Heh. Whomp whomp...off to order two more! ...stupid keel.
I would love to see you lay up some CSM & 1708 Fiberglass on some bulk heads before I have to do my Main bulkhead in my 1988 Catalina 30, I wanna see how you tab and where you would make your cut for the sheet of Marine Grade Plywood because we all know you can't fit a full sheet into the cabin. Love all the videos you make and all the free information you share with us all I appreciate all that you do.
I have two technique tweaks. 1. Pour from full jugs with the spout up, which minimizes drip. 2. Drape slightly oversized piece of plastic wrap over your scale. Spills of next to no concern. Thanks for your very informative and useful videos.
Andy Thank you for the video. Very helpful. If I can take it 1 step further, when I am working with epoxy or fiberglass I do everything in volume. No scale for me to bugger up with resin. Keep It Simple Sammy. So 1 gal of silica is 128 oz and weighs 226 grams. One ounce of silica will weigh 1.77 grams. Using your calculations the following is a general rule of thumb to get you into the thickened epoxy ball park. As a disclaimer I would want to try this on a couple of different sample sizes. Using only 6 oz of mixed epoxy is a small sample. Ketchup - 1 oz of mixed epoxy needs ~ 1 oz of silica, Mayonnaise - 1 oz of mixed epoxy needs ~ 1.4 oz silica, Peanut Butter - 1 oz of mixed epoxy needs ~ 1.8 oz silica,
Great explanation. The instructions on the kits, esters, say to mix resin and hardener before mixing the the thickener. Given the short reaction time and the time to blend in the thickener, it doesn't give much time to apply the mix. I have mixed in about 1/3 of the hardener then started mixing in the thickener and the rest of the hardener toward the end of adding the thickener. Do you have any comments on this. Thanks,
Hey Andy, I am presuming that the boat behind you in this video was painted with Alexseal. Could you tell me what is the hull's paint color (above waterline)? Thank you!
When you were talking about bonding plywood would it beneficial to before hand to coat the plywood with unthickened epoxy? My thinking is it would absorb all that it will. Am I right in thinking that?
It is easy as "1,2,3" -- 1 tub of silica per kit for ketchup, 2 tubs of silica per kit for mayo and 3 tubs of silica per kit for peanut butter. Of course for 2 to 1 epoxy of Total Boat.
Is there any chance you could address doing a fiberglass repair on the keel of a motor yacht up on blocks ? I have a 1966 Hatteras that has fiberglass damage along the keel ( video on UA-cam Lady Barbara 5 3 22 Hull inspection) and was wondering if there is any specific things that help with the repair being upside down over my head. Thanks Tom
Excellent. Subtitles with metric system would be great (temperature, weight, volume). Anyway I think I understood nearly everything. last point : we're not obliged to use a respirator when getting ketchup, mayo or peanut butter out of the fridge ? 🤣🤣 Cheers from old Europe !
I have a question, I have made a flat surface with fiberglass and it's not as flat as I thought, there is a dip in it and water sits there. It collects enough water for it to be annoying. I've already Gel Coated it but I need to fix it. What would you do to fill that dip? Can I fill it with resin, or cabosil and resin, or do I need more chop strand to fill it? Thanks ps. I would never have attempted doing any glassing without your videos.
I’ve begun a quest to learn about fiberglass to make a custom shower pan for a Van build. I’m guessing if it will hold a boat together, then it will hold to a shower pan.
I tried to make fairing compound with poly resin and grindings of fiberglass and mine came out like jelly and would just fall off transom. Not sure what I did wrong. I tried not as much filler but it just ran off to. It was cold and I didn't raise the temp. Not sure
Hey Andy. Thank you for your great tutorials! Have you ever looked at Bakers Percentages? Main ingredient being 100% The others being % weight of the main ingredient: Resin 100% Hardener 50% Silicate 10% Easy to scale and one UOM could make it easier for a lot of folks.
Andy, please consider re-doing this video in metric. Ounces are both a weight and volume. Example: the mayo number you give at 17:45 is "90 oz per 128 oz (aka gallon)". What does that mean?? Is that about 5.5 pounds per gallon?
In Response to that question. I am located on Canada too, and you can get certain Total Boat products shipped, however it is costly and not everything can be shipped. I used to order it and pick up at the border or during a trip to US. However I have not been able to for some time. I previous inquired about Canadian Distribution, however at the time there were no plans for this. Just a little FYI
@@boatworkstoday Thank you. I am on my third boat repair. The prices for epoxy here are crazy. 300 for a 1 gallon kit. Total boat has much better pricing I just need a way to get it here! Have a great Sunday!
I asked TotalBoat that question a couple of weeks ago, they said NO! Very dangerous goods, no can do, etc. I then asked if they're sourcing a distributor overseas but got no reply. So I guess the more people that ask them the greater chance of them eventually going international. Seems like a good product.
You don't miss a thing lol ;-) It's a removable section of railing for loading stuff up top; it's been that way since we bought the place and haven't taken the time to drive them home :-) Yet lol
Great information...I'm also bad in math but how about this: 150g resin, 60g hardener = 210g epoxy. 11g silica for ketchup = 5%, 15g for mayo= 7.5% and 22g for PB = 10%. Does that work? Like making bread.
I felt like Andy when I redid the rotted wood on my 82 wellcraft sportsman fuel tank hatch cut the wood to fit with one inch short on screw hole sides and went to town on peanut butter resin set in the wood and pb the edges so no wood would be in the new screws holes area came out superb and use total boat with the silica power and yes must use respirator with silica power doesn’t even budge w my 300 lbs on it love it along with my fuel tank compartment rebuild with new tank two years ago good info Andy I mixed in the hardener and quickly mix in the silica and slap on the inside of hatch spreed it quickly layed in first wood then pb second even quicker with a helper then pb the sides and smoothed out came out good 🇺🇸🇺🇸🐟🐠🎣🛥🌴⛱🙏🏻🙏🏻

Andy, again spot on. Great video. You just can't imagine your vids have maximize my restore on my 1990 4-winns 205 Sundowner.
Thank you sir.

Hey mate, just found your awesome channel. Can you please do a vid on basalt matting and epixy. Love you work from down under Australia.
Thank you. Great info

Good content! Have you done any videos on refinishing the ever popular 13’ whaler?
Thanks for that info. I always wondered about that. I wonder if that is close to the west system.
I have two technique tweaks. 1. Pour from full jugs with the spout up, which minimizes drip. 2. Drape slightly oversized piece of plastic wrap over your scale. Spills of next to no concern. Thanks for your very informative and useful videos.
Put the scale inside a ziploc bag, it will never get sticky...
Andy Thank you for the video. Very helpful. If I can take it 1 step further, when I am working with epoxy or fiberglass I do everything in volume. No scale for me to bugger up with resin.

Thanks for this! Going one step further, one "fluid ounce" (the volume unit) = 2 tablespoons, and 8 fluid ounces equals one cup.
SUPER INFO!
great video. thank you. what mixing ratio and consistency would you use to repair cobweb like crack in and old spa?
I wish I would’ve seen this video two years ago that’s good information that I didn’t know
Great explanation.
The instructions on the kits, esters, say to mix resin and hardener before mixing the the thickener. Given the short reaction time and the time to blend in the thickener, it doesn't give much time to apply the mix.
I have mixed in about 1/3 of the hardener then started mixing in the thickener and the rest of the hardener toward the end of adding the thickener.
Do you have any comments on this. Thanks,
Hey Andy, I am presuming that the boat behind you in this video was painted with Alexseal. Could you tell me what is the hull's paint color (above waterline)? Thank you!
When you were talking about bonding plywood would it beneficial to before hand to coat the plywood with unthickened epoxy? My thinking is it would absorb all that it will. Am I right in thinking that?
Absolutely! Unfortunately that's a step that many skip
Just make sure you laminate before it cures. Becasue then you're just making a mechanical bond with epoxy on epoxy.
👍👍👍 cool info
I have the impression that this applies mainly to laminating hard parts. Does this apply at all to working with Glass Mat or Cloth? If so, how?
It is easy as "1,2,3" -- 1 tub of silica per kit for ketchup, 2 tubs of silica per kit for mayo and 3 tubs of silica per kit for peanut butter. Of course for 2 to 1 epoxy of Total Boat.
All that on a bun will seal you up...
Can you use silica with fiberglass resin? Or epoxy only
is it ok to use a auto fiber glass for stringes and transon
Is there any chance you could address doing a fiberglass repair on the keel of a motor yacht up on blocks ? I have a 1966 Hatteras that has fiberglass damage along the keel ( video on UA-cam Lady Barbara 5 3 22 Hull inspection) and was wondering if there is any specific things that help with the repair being upside down over my head. Thanks Tom
Excellent. Subtitles with metric system would be great (temperature, weight, volume). Anyway I think I understood nearly everything. last point : we're not obliged to use a respirator when getting ketchup, mayo or peanut butter out of the fridge ? 🤣🤣 Cheers from old Europe !
I have a question,
I have made a flat surface with fiberglass and it's not as flat as I thought, there is a dip in it and water sits there. It collects enough water for it to be annoying. I've already Gel Coated it but I need to fix it. What would you do to fill that dip? Can I fill it with resin, or cabosil and resin, or do I need more chop strand to fill it?

ps. I would never have attempted doing any glassing without your videos.
I see a lot of people using sawdust as a filler. What are your thoughts about that? Any downside to that?
I’ve begun a quest to learn about fiberglass to make a custom shower pan for a Van build. I’m guessing if it will hold a boat together, then it will hold to a shower pan.
For anyone not in the US confused why he is using weight oz for volume it works out to 177ml of epoxy in his 6 oz batch.
Here's a question opposite of thickening. What do you recommend to thin epoxy out? I've read to warm it up in the jug in a warm water
But I've heard that can shorten working time.
I tried to make fairing compound with poly resin and grindings of fiberglass and mine came out like jelly and would just fall off transom. Not sure what I did wrong. I tried not as much filler but it just ran off to. It was cold and I didn't raise the temp. Not sure
Fairing would be more along the lines of a mixture of (mostly) micro-ballons and silica :-)
Hey Andy. Thank you for your great tutorials!
Have you ever looked at Bakers Percentages?
Main ingredient being 100%
The others being % weight of the main ingredient:
Resin 100%
Hardener 50%
Silicate 10%
Easy to scale and one UOM could make it easier for a lot of folks.
Hey Andy - you're in Michigan now - it's not mayonnaise, it's miracle whip LOL (Another Andy originally from the Keweenaw)
One could mix this in a sandblasting cabinet?
Should I copyright this idea?🙂
Vinyl-Ester thickening essentially the same?
Andy, please consider re-doing this video in metric. Ounces are both a weight and volume. Example: the mayo number you give at 17:45 is "90 oz per 128 oz (aka gallon)". What does that mean?? Is that about 5.5 pounds per gallon?
👍👍
use wood flour
, can you use Wheat flour as a thickener ?
Hello from Canada land! Andy do you know if any total boat suppliers that ship internationally? I am having a difficult time finding a supplier.
Unfortunately I don't think so :-/ Might be worth giving them a call and asking though!
In Response to that question. I am located on Canada too, and you can get certain Total Boat products shipped, however it is costly and not everything can be shipped.
I used to order it and pick up at the border or during a trip to US. However I have not been able to for some time. I previous inquired about Canadian Distribution, however at the time there were no plans for this.

Is humidity a factor?
Not really :-) Humidity does come into play when Amine Blush is concerned but this 2:1 epoxy is Amine Blush free :-)
How about finish driving those 2 screws in the mezzanine handrail post.
You don't miss a thing lol ;-) It's a removable section of railing for loading stuff up top; it's been that way since we bought the place and haven't taken the time to drive them home :-) Yet lol
If you put a batch of thickened epoxy into a vacuum chamber and evacuate the air bubbles. It will be much stronger and easier to work with.
Silica is a bugger to mix….but if you leave it for a while, the lumps magically disappear
Great information...I'm also bad in math but how about this: 150g resin, 60g hardener = 210g epoxy. 11g silica for ketchup = 5%, 15g for mayo= 7.5% and 22g for PB = 10%. Does that work? Like making bread.
Hi, Are you out of focus or is it my screen that do not work correctly?
lets get the boat finished brother
Been sick past couple weeks, this was all I could get done. On the mend now
You need to know these things for projected profit and loss margins otherwise you'll loose your ass on supplies.
Andy you are definitely weird, but so is most of us I suspect so it's ok
Ah, peanut butter is the fabricated one, not the biological one. That has too much oil in it, which is more like the ketchup one!
If you can't measure it, you have nothing
I felt like Andy when I redid the rotted wood on my 82 wellcraft sportsman fuel tank hatch cut the wood to fit with one inch short on screw hole sides and went to town on peanut butter resin set in the wood and pb the edges so no wood would be in the new screws holes area came out superb and use total boat with the silica power and yes must use respirator with silica power doesn’t even budge w my 300 lbs on it love it along with my fuel tank compartment rebuild with new tank two years ago good info Andy I mixed in the hardener and quickly mix in the silica and slap on the inside of hatch spreed it quickly layed in first wood then pb second even quicker with a helper then pb the sides and smoothed out came out good 🇺🇸🇺🇸🐟🐠🎣🛥🌴⛱🙏🏻🙏🏻
