If you have never used fiberglass before, THIS is the video for you! Fiberglass cloth selection can be confusing, there are so MANY choices! Don't let that stress you out! MOST fiberglass work is done with 5 basic fabrics. Learn their uses, and how to cut and shape raw fiber glass the easy way in this video. This is a follow up video to several other HOW TO fiberglass videos here on the channel, so feel free to check them out. We try really hard NOT to fill our videos with lots of fluff or filler content, so be sure to watch all the way to the end, or you might miss out on some useful information. Fiber glass work is not rocket science, BUT you do need to follow ALL the steps or your work may not turn out right. If you have a question about fiberglass use and application, feel free to comment below. I will do my best to answer your questions. If you find this video helpful, please remember to subscribe, like, comment and share with a friend. Thanks so much for watching!

@FishBumpTV 4 ай бұрын

Thanks! 1oz is just easier to wet out because it is thinner material than 1.5 oz. They make 3/4 Oz, but I find it to be somewhat delicate to handle. Just remember that csm doesn't work well with epoxy resins. Polyester and vinyl Ester are fine with csm. Hope this helps, thanks for watching!

In this area, they call the CSM matt "angel hair" and the roven woven "matt". Only other thing they use is "chopped glass" which everyone seems to hate. Funny how you get colloquial terms in different areas.

@FishBumpTV 4 ай бұрын

Glad you are enjoying the videos! I have done some body work on cars and trucks in the past, but boats are obviously our main area of expertise. If I understand you correctly, I would feather or transition the glass as you get to the edges or seams of the fender or hood. If it is a body line, or crease you may have to use a premium body filler or putty to get the shape you need. I will try to do a video on body work and fairing out glass soon. Hope this helps, thanks for watching!

Capt joe, I see in your videos you lay up your coosa with alot of vinyl Esther resin and you run 1708 by axial and finish it off with CSM is that because your CSM does not have styrene bonding in it ?

@jamincorrodi8084 3 ай бұрын

Nice and concise Capitan! A follow up video would be appreciated: How do you come up with a layup schedule? How thick is a layer of cloth? Do you always do mat first and last, or is it not needed first with the xx08 fabrics? i.e. 1.5 oz mat - 1708 - 1808 - 1708 -1.5oz mat? Mat matters more for visual finished surface, or is it needed to hold extra resin for a good bond (or both)? How do you estimate how much material to buy? is there an waste percentage that is common, 10%? How much resin/yard would you estimate? How many layers can do in a single layup? How do you decide to have a core vs solid glass?

Depends on what you are doing but always put first and last mat it gives better finish and let you easier remove bubbles from product than when you leave rowing mat Layer of mat 450 gram is about 0.8mm with resin and its about 1 kg its very dependent on temperature with higher temperature you use less resin its just more liquid water like when in low temps it gets more jelly and you ideally should put about 70% of fiberglass but its kinda unrealistic in hand made laminate its way easier to work with it if you put more resin :S Material is estimated by square meters at least here in eu and yea 10% is about right but ISO reduces it to like 6% or something around You see if you put mat and rowing on gelcoat you get nasty looking imprint of rowing so to avid that you should put like 3 or 4 layers of mat and then put rowing How many layers you can put at once? well it also depends on what initiator you use with peroxide its about 5 "450 mat+650 rowing in m+r+m+r+m" but it also varies with temperature with about 27c you get first curing in about an hour with 1% of initiator "1% its 10ml of initiator for 1kg of resin" when in 20c you put like 2% with curox initiator you can put up to 9 layers also depends on temperature be aware tho product may bend or warp in a undesired way its better to put less layers at the time most of the time you decide by cost for example you need to laminate some part non visible in the end so you put two mat layers and call it a day if you use mat rowing mat you use more materials than needed to achieve the same result for example you make a form and you want to reinforce walls so the keep shape so instead of putting few more layers you put instead few pieces of wood planks and laminate them with two mats and get sturdy wall for cheep we use steel beams "heavy" or wood planks "mid" poliuretan foam "light" for reinforcements for good bond its better to know time of curing for gelcoat its better to put mat layers when gelcoat is harden and slighty sticky or when is squeeky when move your fingers on surface for mat its better when its harden and dry try to scratch it using metal blade or nail if leave scratch its good to go if leaves hairs then wait and before putting another layers just sand it a little for better bonding about gramature of fiber glass mat for more complicated shapes put smaller gramature like 150 for first layer when less complicated or flat surfaces you can put like 450 or 800 gram mat for rowing for flat its good 90 degre single woven but for complicated shapes its better double woven rowing

Or should I use some biaxial fabric like you did on your repair video? The damage on my boat looks similar and might be a through hole. If the standard mat and woven roving is sufficient, what thickness should I buy regarding woven roving?

@FishBumpTV 28 күн бұрын

Glad you are enjoying the videos! Yes, you can use mat and woven roven instead of 1708 if you prefer. Just remember to always start and finish with mat. It bonds better on the first layer than roven, and has better cosmetics on the last coat. I like 18 Oz roven personally. I hope this helps and thanks for watching!

I usually recommend removing all of the gelcoat and get down to solid fiberglass. I usually use a 24 grit sanding disc to put a very aggressive tooth or surface on the original fiberglass so that the new fiberglass can bond better. I hope this helps and thanks for watching!

That could be a serious structural problem and might require some serious fiberglass repair work. Most damage on boats could be considered cosmetic, but if it is leaking water into the hull, that would be structural damage. We have not done any videos on that kind of repair work, and it might be something you should talk to a repair shop about. At least see what they would have to say.

@FishBumpTV 4 ай бұрын

It varies from boat to boat. Large boats require more glass than small ones. Commercial work boats are usually built heavier than pleasure boats. So there are many factors. Also just plain experience working with many boat of different sizes you get to see what works. Our 29 ft custom charter boat we built has 2 layers of 1.5 Oz csm for a skin coat, then 10 layers of biaxial on the hull bottom. That yields around a 1/2 inch thick laminate on all flat panels. Nearly 1 inch where it laps in the keel and chines. Hope this helps, thanks for watching!

@kyyurtman1416 4 ай бұрын

Tearing the Matte is the same principle as finish drywall or using body filler and even spray painting.. We call it feathering out the edges. Tearing the matte creates the feathering effect when transitioning to another surface. It can reduce or even remove the visual layer change.
