hello its amazing how to make liquid polyester to fire reardant ? just antimony or other powder also needs?

Hello, thank you for this wonderful demonstration, I'm about to carry out to a similar experiment and I'm grateful for this video. I wanted to ask tho, the mixing ratio prescribed the company for part 1 and 2 is 1 to 1.06 but you used 1:1. Does that not cause any issues at all?

Answered my question for sure. Thanks. I thought it needed to be sandwhiched between another chop strand matt before applying another biaxel matt.

Very helpful explanation

Would you say the mould is not compromised with the Thickened Latex ? I was unsure whether to use the Thickener.

Many thanks, Very Useful.

Saw this at reception the other week. Great work!

Where U warking I know to use Faber glass to laminate I'm in SA KZN

Greetings fom australia fred . Great job you have all done . Stephen , anne smalls nephew.

Love the video but hate the music!

Always find it impressive when seller creates videos that are objecttive and informative without salles woffle. Its rare and only happens up North.

I'm working on bonding ABS material with resin but having trouble finding the right fit. I've tried both epoxy and polyester resin, but the results haven't been ideal-FRP hardens once it dries, while ABS remains flexible, so they don’t bond well together. Does anyone have recommendations on a resin or adhesive that could work better for this? I'd appreciate any insights or suggestions

A little bragging here. I am the gentleman who invented the corner roller. I'm also the inventor of a roller that is made of something that we could call a bottle brush. Whenever I made a mold I avoided a sharp 90° or less corner. Whenever a sharp corner was necessary I had a solution for that as well. I made a compound of resin, fumed silica and 3 mm glass roving. The compound is made to be very thick. The solution it's not foolproof but I had very little problem with it. Yes, I'm old as the hills and twice as Dusty.

This is very useful and encourages me to get back into doing some fibre-glassing.

Interesting. At some point soon I need to build an odd sized (7x16') semi permanent shed that can be assembled by one person. I initially thought of welding up 6x4 and 7x4 steel box section frames for the side walls, a pair of 3'6" wide panels with the sloped roof angle on the top for the back wall, and a couple of door frame halves for the front, then skinning all these in painted 9mm plywood. But these panels would end up being ridiculously heavy......... And have you seen the price of plywood at the minute !!! I've never had much luck with fibreglass moulding in the past, but after seeing this video I'm thinking I might need to look into the possibility (And costs involved) of making the walls in a similar way to how you made these doors. Maybe if I encapsulated a "Batten wood" frame around the edges, and a couple vertical wooden stringers up the middle, it might even be strong enough without most of the metal framework? I just need to work out what kind of loads the walls could see if the corrugated sheet roof I'm intending to use had, for example, a foot of snow all across it, and how much it would cost in materials per panel to make them structural enough to carry that. 🤔

Hello, great video, thank you. On an avg how much area would be covered by 1kg of gel coat.

Can I use the PU skin to cover a Styrofoam head??

I am also a fiberglass craftsman

I was doing it wrong, i was mixing the gelcoat with 5-10% styrene to thin it for brush on application.

Amazing that you can still talk and breathe with that polyester resin next under your nose..it must be epoxy resin…but you said it isnt..😮 Not a good example for a youtube course..just put some mask on, please..

Thanks! It is both surprising and disappointing when this happens. Mine happened on the first layer of gelcoat painted into the mold, before anything else was layered on top of it. Possibly from too much styrene mixed in at the factory. Mixing the special tooling gelcoat 1:1 with regular white gelcoat and adding a lot of hardener seemed to prevent it. This has not happened again since I finished that one batch of tooling gelcoat.

Why not roller for a textured finish?

What about outside corners?

Did you say flow coat is good for the inside of a hull? I have a fibreglass hull which is rough inside (under tank etc) just want to brush something on to help the water flow out quicker…. Any advice would be much appreciated

How can I get some of your tools in Ghana west Africa

I am job

If we want 2 layers (external ..not in mold)..can we use first gel coat..leave it for a day and then apply topcoat ?will the gel coat cure with top coat on top of it?thanks in advance..

hello grate mask also do you teach mask making ? also where can i get the material's that u used in this video?? i am in the uk

thanks a lot for this video

I came here to learn a little more about casting a fiberglass part in a two part mold. This was exactly what I needed! Thank you. KZbin channels like this really do the lords work for specific technical knowledge.

Thank you! 🙏🏽

❤❤

You talk, but in the end, you said nothing. Another useless video. Do you know something from fiberglassing?

Nice job....I want to apply some very thin ply as a second skin over fibreglass to make inside boat look nicer.......could i use No nails, Gripfill or some kind of variations to stick panels on.

Haha when you crease glass you break the glass which is what gives strength, this dude knows what he is doing lol

That looks awful. That's not a flow coat, it's simply gelcoat with wax in it! The idea of a flow coat is that it flows to produce a flat surface.

Please i need this chemical... please drop me ur contact

2:55 why would you mix ‘bondo’ with a round-end stick instead of a spreader or a putty knife??!! This seems nuts.

can i use vinyl ester as a resin while second layup of chopped strand mat

How do I get the chemical

Thanks for your tip's❤ from sri lanka 🇱🇰

So much for helping me overcome this suffering! I'm from Brazil!

Get a closed container big enough for the brushes to stand inside then place a glass inside nd fill half way with acetone then put the brushes inside after wiping as much resin as u can with a old cloth and then close the lid on the container till u next need to use the brush. Leave it somewhere u wont get direct sunlight and make the container is air tight. Take the brush out nd dry it with a cloth nd leave it for 2 mins for the acetone to dry out nd use it. The brush will feel like brand new every time

Excellent, excellent, excellent instruction. Thank you!

how do you know if it is bwn yellow or black you need?

Hi I’m in the process of restoring my boat and want to repaint it… my question is after gelcoating some fibreglass patch ups that I have done can a apply flowcoat over the whole boat after lightly sanding it? Looking forward to any advise thank you

So is it recommended to have a bit of air circulation like a desk fan blowing across the part? No heat just air moving.

Thank you very much, sir. I've faced this problem myself and till before this video, I couldn't have figured out why this happens. We've searched and searched for days and never got the answer. Appreciate this video.

Thank you ❤
