- Repairing a Fibreglass Crack doesn't have to be daunting. We've put together an easy to follow guide specifically aimed at those new to fibreglass!
As always if you missed any of the steps outlined in the video, please keep reading. If you have any questions or would like to buy any of the products featured in the video, you can find them (and us!) at www.fibreglass....
Step 1: Familiarise yourself with any MSDS or TDS sheets prior to purchasing or using the fibreglass materials. These products are hazardous and have a strong odour so great care should be taken on how and where you use them.
Step 2: Inspect the area to be repaired. In this case we are using an old fibreglass lid. Sand the inside of the product using 80 grade sandpaper.
Step 3: Take a clean cloth and wipe down the sanded area with Acetone.
Step 4: Weigh out 0.5kg of resin. Add catalyst at a rate of 2% e.g. 20ml for every 1kg and mix well. 2% applies for room temperatures.
Step 5: Brush on the resin and apply the pre-cut mat to suit your area to be repaired. Apply more resin and roll in with a paddle roller. Repeat this process until three layers have been applied.
Step 6: Leave to cure at room temperature for 3-4 hours.
Step 7: When the resin has fully cured, sand the area with 80 grade sandpaper and clean the dust with Acetone.
Step 8: Sand the cracked area on the outside of the product using 80 grade sandpaper.
Step 9: Using a cloth and Acetone, clean the dust from the sanded area.
Step 10: Mix 0.1kg (100g) of Gelcoat, adding catalyst at a rate of 2% - again using room temperatures. Mix thoroughly.
Step 11: Using a mixing stick, apply Gelcoat to the cracked area.
Step 12: Carefully apply masking tape, lifting back to ensure that no air pockets have been trapped in the Gelcoat.
Step 13: Leave to dry for 3-4 hours at room temperature.
Step 14: Remove masking tape and clean down with Acetone.
Step 15: Sand the cured Gelcoat starting with 180 grade sandpaper and finish with 1000 grade. Wet the sandpaper with water first.
Step 16: Apply Farecla compound to shine and finish the repair!
That was brilliant. Straight forward without all the bullshit dialogue.
Great video and very helpful!, thanks!
Music is annoying..! Had to mute it.
How do I repair it if I can’t get to the backside of the crack
just throw gel in there lmao
This is exactly how I fixed my bathtub and pool slide 😂
I'm looking to repair an old pool slide that has a lot of cracks in it- did you use fiber glass mats in yours? I'm trying to figure out the best process
@@jessicakelly204 that’s actually just what I did. The mats are thicker than the sheets so I didn’t have to use as many layers. I let it cure for an entire day, sanded the hell out of it and painted it with rusteoleum bathtub spray paint. It’s not completely blended but it’s safe and looks good enough haha
Perfect!!
What are the names of chemicals and ratio
Nice one
Good video... rubbish music
what chemical can be use to fix a broken mannequin??
Very good video - however it's difficult to work with units like kg and percentages for resin and catalyst, is there a reference using the units on the product labels - ie: ounces? Ratios are tough too...hard to be accurate. And how do these ratios change with temperature? Would you recommend doing this in 40-degree weather? Second question is, if the crack is deeper, and your first application of gelcoat still leaves a depression, can you simply repeat the same process to add more material? How is the gelcoat surface prepared for a second "coat"? Lastly, will any type of masking tape work or is this a specific type for this application?
Tempature does make a difference. But sometimes you have no choice. Can keep resin, hardner, & part inside to keep warm/warmer till ready to work on it. A spot light or heaters can keep things warm too. But if warmeded up to much, the hardner may kick in sooner. You can always put more hardner in colder temperatures.
I recommend gelcoating for skimming layers. Anything deep I’d lay some glass down on a propoly prepped surface first, , then gelcoat on top of that. Remember gelcoat doesn’t have much structural properties.
Learn the metric system...
@@christerboysen2465 Which one? There at least three or four metric systems floating around the world. The Japanese have their JAS system. The Germans the DIN and the French have something unexplainable. The English are trying to standardize but it's slow. The whole world is confused about the metric systems, Plural. The USA kicks in 250 Million dollars every year trying to get the metric standards agreed upon world wide, (ISO) yet bassackwards people make fun of us. Truth is the US system has most standards set in stone, more so than the rest of the world and our manufacturing shows it. My shop ordered 6mm screws from Mexico and 6mm nuts from Japan and they would not screw together. The meter and the yard are both arbitrary. Accuracy is wholly dependent on the instrument/operator doing the measuring.
@@650gringo simply use the average of all the different metric systems, what could go wrong?
@@christerboysen2465 Agreed. They should just use the metric system, but they won't they just keep finding stupid excuses to keep doing stupid stuff. For that is the American way lol!
Does this work for bath tubs crack?
Yes
So one has to weight the liquid then add 2%.......I don't think that explanation makes it any easier if someone understands the metric system or not. You are dealing with liquids, can't there be something like mix this much ml of resin to this much of ml of catalyst? Sorry, this is confusing that way it is presented and has nothing to do with metric or standard. I can say for certain that some of you bashing the standard system don't even know to figure out what 2% of 0.5 kg is.
wow
Can it also a Crack mannequin
easy on a Lid, and by a Pro....LOL
