Rookie here: It is my understanding that "mat" does not work well with epoxy due to the binders in the mat; therefore, can 1708, which does work well with epoxy (?), be used exclusively without applying the mat as a base? I'm preparing to install a reinforcement transom in an old I/O that I'm transitioning to an outboard motor. I'm using 2-pieces of 3/4" plywood for the project and will combine that with the transom already in place....the objective is to extend the transom to the bulkhead and pay special attention to glassing-in the transom ends to the fiberglass hull. I've have already ordered 90-feet x 50" of 1708 and a couple of gallons of "Total Boat" epoxy and slow hardener. I'm in SW Florida and the temps here are now in the mid to upper 80's during the day - humid. It is good protocol to use 1708 exclusively with the epoxy to both seal the plywood transom, add strength and integrity to the wood while also feathering the 1708 to the fiberglass inner hull to counter the forces of the motor on the transom? I'm a little confused concerning the application of mat or strand, which requires a polyester resin (?) and 1708 which works with epoxy for strength. Thank you for your help...much appreciated. Your videos are invaluable.
@FishBumpTV3 ай бұрын
Glad you are enjoying the videos! Yes, mat does not work as well with epoxy as it does with polyester or vinyl Ester resins. Epoxy doesn't have the solvents in the resin that dissolves the binders in the mat, which makes it a little more difficult to work with. Most 1708 has a layer of 3/4 Oz csm stitched to the backside of the main 45 degree glass strands, but it is not held together with binders like pure csm is. 1708, 1808, and 6 Oz finishing clothe are the most popular fiberglass fabrics when working with epoxy resins. I hope this helps and best of luck with your project!

I am restoring a 1981 TMI Sailboat (Chrysler design) and have large areas such as in the sail lockers and settees that need mat and woven or 1708 to restabilze the surface to re-gelcoat. I know epoxy covers nearly all, but I would like to use vinylester or polyester resin - For economy of material mainly. How do I know if the original resin by manufacturer is compatible with vinylester or polyester resin? Thank you

Glad you are enjoying the videos! The vast majority of fiberglass boats ever built are going to be polyester resin. Probably only 5 percent or less are built with epoxy. There is not any easy way that I know of to test your boat, but I can almost guarantee that it is polyester. So using a good quality iso polyester laminating resin or vinyl Ester resin should work well. There are links below our video descriptions if you would like to use the same kinds of resin we use in our videos. I hope this helps and thanks for watching!

Ok I will try to make this as short as possible. I am working a Stratos late 80's and they used mostly woven-roven on stringers and I think that is where a lot of failures come from because of where it is woven seems that it created holes that water could get through and the quality of the fiberglassing was poor. In your professional opinion which I value highly! how many layers of 1708 would you use to equal woven-roven on the stringers and other places that they have used it. I want to use only 1708 and chopped strand. My stringers are so bad that there is just a skeleton of fiberglass with a few chunks of wood in the bottom of them. I will use all of the techniques I have learned from you to make this boat better than it ever was. I will be using only Coosa board for it. To sum it all up I think you have the best boat repair DIY videos on KZbin and I commend you for starting this channel. Thanks so much and have a great day!
@FishBumpTV3 ай бұрын
Glad you are enjoying the videos on the channel and finding them helpful! We used 3 layer of 1708 on each side of the Coosa stringers on our 29, and it is very solid. Be sure to consider the quality of the resin as well. A quality isophthalic polyester laminating resin, or even better a vinyl Ester resin is really going to help improve the strength and quality of the job. I hope this helps and wish we the best with your restoration project!
@DarkSevariant3 ай бұрын
One thing I would mention, internet says, it takes about a gallon of resin, to wet out a yard of 1808. Joe, if I didn't care about looks, could I use complete mat for both layers, and call it done? Then just sand out the edges prior to paint? The Roven is nice, but I'm not going to fiberglass the hull of my my 50' Beneteau Man, that finishing cloth is transparent, with a nice finish.

@FishBumpTV7 ай бұрын
There is no one resin that is perfect for all applications. Most boats are built of polyester resins. But once the poly resin has fully cured, you are relying on a mechanical bond, vs a chemical bond when adding new stringers, transom etc. As far as secondary bonding goes, epoxy is the best, followed by vinyl Ester, then polyester. They can all be used with success in certain applications. A clean surface, with VERY aggressive grinder marks or tooth is critical. We get this by using a 24 grit disc on a high speed grinder. Then vacuum the surface, and wipe down with acetone. I plan on doing a video on this topic very soon. I hope this helps. Thanks for watching!

Hey Joe a 3' deep 16' x 40' barge type bottom for a house boat. How much resin would I need please.
@FishBumpTV7 ай бұрын
That's a good question. Different Temps, plywood, type of glass fabric and how many layers as well as the person doing the work could all have an effect on how much resin you could use on a job like that. You can usually figure on approx 2 to 3 Oz of resin used per Sq ft covered with 1 layer of 1708 biaxial. Based on your Diminsions you are looking at 880 or so Sq ft. Let's round up to 900 Sq ft x 3 Oz per Sq ft on the high end would be 2700 ozs divided by 128 Oz per gallon would be 21 gallons of resin used approximately for one layer.I would recommend at least 2 or 3 layers of biaxial with a finish coat of csm or mat as well, for a vessel this size. This is just just my opinion of course! And a ballpark estimate. You should do your own calculations and research, as well as talk to your local fiberglass and resin suppliers. Safety is always a factor on a project like this so you may also want to pay for some more technical advice from a boat builder marine surveyor or boat repairman in your area. Hope this helps, thanks for watching!

What fiberglass cover should i use to cover these fins with so they hold well to the base? I was thinking 2 layers of 1708 and and extra 6" wide tape joint of 1708 on the angle area where they connect to the base.

Glad you are enjoying the videos! The 1708 biaxial is going to be the stronger of the two materials. The csm is good for initial bonding and finish cosmetics. You should use the materials where there best qualities will work for you. We plan on doing more structural fiberglass videos soon as it is much easier to discuss best techniques and options that way. Hopes this helps, thanks for watching!

Joe, are you familiar with the product Plascore, a honeycomb material made by Plascore, Inc, in Zeeland, Michigan, and if so would it be a good substrate for fiber glassing a boat deck? Your time and consideration is apreciated.

Sorry, I am not familiar with that product. I am a big fan of the Coosa board that we used to build our 29 ft charter boats. We have had really good performance out of it! Hope this helps, thanks for watching!

you mention 1oz. CSM. I have been using 1.5 oz. and sometimes 2oz. Csm. should i be using 1oz? i hope this isnt a stupid question. but yes i have some trouble with conforming to bends.

I like the 1 Oz because it works out much easier in my opinion, and remember that csm doesn't work as well with epoxy resin as it does with polyester and vinyl ester resins. I hope this helps and thanks for watching!

you mentioned on working with fiberglass, kay down CSM first then woven roving, would it be safe if we do CSM then woven roving then another woven roving then biaxial or just alternate the material like CSM then woven roving then biaxial? thank you. please reply.
@FishBumpTV8 ай бұрын
The only fiberglass fabric that you should not laminate on itself over and over again is woven roven. If you have csm and roven to work with, you would always start with csm then roven then csm etc. You would always want to start and finish with csm on any project when you are also using roven. With 1708 and 1808 you can stack them on themselves over and over again with no problem. With 1708 and 1808 you can use csm on the last layer as a better cosmetic finish. You can also use layer after layer of csm stacked on itself with no bonding issues, it just will not be as strong as alternating layers of csm first then roven then csm. You may want to watch the video How to fiberglass over plywood, which we just did it should be helpful.. I also offer consulting on an hourly fee for folks that need more of my time. Hope that helps ,and good luck with your project!

Do I need to turn my fiberglass boat over to do repairs on 1ft crack below the water line. Also, do I need to use epoxy resin?
@FishBumpTV7 ай бұрын
It is easier to do repair work right side up if that is an option. If it is a smaller boat, I would turn it over. If the damage is below the waterline that makes it more critical, Could be structural damage. Damaged glass should be removed, and new glass applied. We don't currently have a video detailing that process, but hope to have one soon. Yes, epoxy is the premium choice for that kind of repair, followed by vinyl and polyester resins. Hope this helps, good luck with your project!

@FishBumpTV5 күн бұрын
1 layer of 1708 biaxial, followed by a layer of 1oz csm is what I put on the floor of our 29. We doubled that amount in all of the corners for strength. The vinyl ester resin from fiberglass warehouse would work very good for that application. Of course you could put down more glass than that, but I wouldn't put down any less.

Hey Joe, what glass and what layering would you recommend to replace my stringers with styrofoam or EPS?
@FishBumpTV7 ай бұрын
There are many different ways stringers can be built. I imagine the original stringer were lumber or plywood and they rotted out. If that is the case I would go back with Coosa board in the same thickness as the original, or slightly thicker. Two layers glued and screwed together with with the joints staggered is the way to go. On most boats 3 layer of 1708 with the edges staggered works good in most cases. We have a video or two where we are working on the stringers and glassing them in our boatbuilding series that might be helpful. Stringers are not an area to take shortcuts or skimp on materials, so always a good idea to go on the heavy duty side of things. Of course these are just suggestions, and every boat is different. Hope this helps, and thanks for watching!

I am 100,000% against glassing over wood (for obvious reasons). What type of composite decking sheets are boat manufacturers using these days, that they are fiberglassing glassing over? Just like the boat in the background in this video. Not an ounce of wood in it.

@@trentmiller7532 Coosa is the main plywood replacement core. There are other lightweight cores like divinicell and airex, but they have to be glassed pretty heavily on both sides to get any real strength.
