Laminating into Tight Corners - Expert with 30yrs experience Shows 6 Methods (+ what to avoid!)

[@THIAUDI]

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

Great tips thanks. 👍

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.

I call it 6mm confetti! Awesome video

What about outside corners?

[@AndyGoesOutside]

did you let the chop strands and resin cure or harden at all in the corner before continuing with the regular layer of matt @2:40?

[@ecfibreglassuk]

Hi, We just went straight on with the fibreglass matting. If you let the 6mm chops cure you could end up with pull marks in the gelcoat side where the thick 6mm filler has cured shrunk back applying at least one layer of matting over prevents this.

How to polishing and painting processe fiber items

[@ecfibreglassuk]

for painting you would need to speak to a paint supply to get their advice on suitable primers for their products but most fibreglass laminates will take car primers and paints, also marine primers and paints. for polishing fibreglass/GRP (Glass reinforced plastic) you can use products such as the farecla or ROAR range of polishes from our website, unfortunately we do not have a video on polishing.

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

[@ecfibreglassuk]

There are certainly challenges trying to bond thermoplastics with various resins. Most resins will not bond to ABS, PVC, HDPE etc Polyester resins are a definite no, Epoxies can bond if the surface is keyed enough and the epoxy type is flexible. Epoxies, such as West system’s G-flex, can provide good mechanical bonding for flexible ABS parts, the effectiveness largely depends on the degree of flexibility in the ABS part. There is a video on KZbin where an ABS canoe is cut in half and bonded back together with G-flex then totally thrown about to show how strong the repair is kzbin.info/www/bejne/jXS2YaSoeZiAh7s However, if the bonded parts experience significant movement, solutions like plastic welding might be the most durable option.

Please can we apply gelcoat on silicone mold ?

[@ecfibreglassuk]

Gelcoats can sometimes come out of a silicone mould quite tacky due to a reaction with most standard silicone. So it best to test first with your particular silicone. Addition cure silicone, sometimes refereed to as platinum cure silicone, can usually be gelcoated without issues as shown in this video approx 6.57minutes in.... kzbin.info/www/bejne/kIO9q4qHbd6roZo bear in mind however that gelcoats are a polyester and contain styrene solvents which can eventually dry out rubber moulds and reduce their lifespan compared to plasters ect.

You coumd have tested polyester glue in corner. That s the method I personally use most of the time.
