FIBERLGASS CRACK REPAIR | HOW TO REPAIR A CRACK IN A FIBERGLASS BATHTUB USING FOAM & BONDO GLASS

Welcome back to DP TUBS for another Fiberglass Crack Repair video. This fiberglass bathtub had a crack that needed just a little foam support as I patched it back up using bondo glass. Don't forget to message me and follow me on instagram to see more of my work.

Same..been on my own for 10 years...3 special needs children...I do everything literally...even had to do my entire roof on my own...electrical panel as well...I also work on my vehicle...I can do anything with God..& you tube!!

[@jaimerogers6379]

I'm in the process of doing the same thing.

[@brucefaith]

Thank you for this video. I had to patch a large crack that had been "patched" previously by a house cheap flipper and this was such an amazing step by step. Saved me.

[@frankstarr3359]

Thanks for posting this video. This will keep me from having to replace my tub. 👍🏻

[@sabrinaconery3471]

Thank you so much for this video. I'm searching for a way to repair my tub and a friend recommended using bondo glass and now I feel confident that adding the spray foam underneath will make a big difference in the longevity of the repair.

[@FunkyColdMedinaDIY]

Great job! Ive seen videos of others using flex seal but I think i will use the bondo glass since it has the fibers in it. Thank you very much and have a blessed day😁😎✌️

[@mistermister124]

I have this same exact issue and I will follow your instruction to the letter. Thank you. A month ago I really did think I had to do a total remodel so I am so happy now. Thank you

[@DPTubs]

Awesome! Let me know how it goes

[@mikegarcia7844]

Great video, straight to the point.

[@charlietan3770]

Had few cracks on bathtub with 1 really large one, will try out the PU Foam fill the hollow space to see if it's able to sustain the weight first. Then maybe later only do something about cosmetic crack on top. Thanks for sharing this, really informative.

[@kelvinlyons3401]

All got to say is that this is great video

[@fredborchuck1532]

Useful video. I would like to see a video of you doing a fiberglass repair on the inside wall of a tub where you have to work on a vertical surface.

[@DPTubs]

I have a few videos like that already! Check out the fiberglass repairs or fiberglass hole repairs videos of mine. Search “DP tubs fiberglass hole repair”

[@eddiegutierrez3524]

That was a great tutorial thank you so much for your video..

[@redkay8442]

I've been trying to just use flex seal. This is amazing. Once I have to fix it again [been multiple bandaid fixes], I'll get the supplied and try. Thank you again!

[@GetFamousORDIETRYING]

that flex seal shit works great, i used it on mine too, but check it out sooner than later. after a few months the epoxy and flex patch i used started leaking and it almost rusted through an iron gas line thats under it in my floor . get a peek theres gotta be an access hole somewhere

[@deadfury54]

Thank god I found a video on this and it’s so well done. There’s about a 6-8” crack in my bathtub insert and don’t have the money or materials to replace it

[@juantrevino8608]

Great job! Im ready to do a couple of wholes in a shower.

[@jasonbaxter5727]

Great job on the tutorial. I do bathtub repair as well. We don’t use paint from a can though. There is a product called prevail. It’s an aerosol can with a removable jar for your paint. This allows you to get an exact match by mixing your paint. I’m sure you know of it but just wanted to throw it out there for you. Get back with me if you’d like to bounce some ideas off each other.

[@Apexpropertycare]

Hey man, I’m in Canada and just getting started in the biz. Any info would be great that you could share with myself, I also wanted to ask where you get this “Prevail” product as I can’t find it online anywhere?!?! Thanks again Leo ✌🏼

Yo DP, gotta an acrylic hairline crack on new tub. Just need it to be watertight, are the tub repair kits any count?

[@cdetterer]

Would you use the bondo glass on a cracked plastic mobile home tub?

[@supra8544]

Great demo. How do I find someone to fix my cracked tube?

[@Mediocretwinmom]

Will this work for a crack next to the drain on the wall/curve of the tub?

[@AlloyedFrequencies]

very nice thank you

[@TOMA-ny7gg]

I have same crack in the floor Can i use only the bondo glass or i need to buy bondo all purpose putty(which replaced by original filler)to put on that

[@juanllanez2103]

What’s the cost for repairing small crack?

[@AdelRamadhan-qz3it]

Hi is the material you used same as the panelbeater used( the fibreglass)

[@jayrmz8302]

The final time you added bondo did you also add harder?

[@enkrypt3d]

I tried this with JB weld on my acrylic hot tub and thought I had it perfectly sealed until it popped open again as soon as the hot water hit it again.... ugh so back to the drawing board again.

[@anthonyschlecht5520]

Is it possible to patch a crack where the tub drain is?

[@mikes164]

Would this process work on a larger surface area…. Say a lil less than a square foot?

[@CaseyCBurns-xt1pw]

How long before one can use the tub as normal and why? Is it to let the paint finish curing or other reasons?

[@melissasaint3283]

Question, because I can't find a video on this on your channel so far... I just discovered a lengthy crack in a low projecting shelf that is part of our fiberglass shower. Best guess, one of my young children has been sitting on it for some little kid spa luxury during shower time...the shelf absolutely has give when I gently push. Is that repairable? Should I fill it with foam? I really dont care about how it looks or plan to use the shelf to hold anything (including butts!) From now on, I just need it to not leak into the wall or under the tub!

[@sabrinaconery3471]

Question: how long do you wait between each step? After the spray foam? After each layer of bondo glass?

[@melissamcgee5572]

How far do i drill? The pan is very thin an then its a dark woody material

[@JohnCiambriello]

Hey there, I’ve seen you use Krylon tub and tile, rest-oleum, satin, like in this video, and the rust-oleum appliance sprays. Why do you keep changing it up and which is best? A video comparing the outcomes or pros and cons of each would be wonderful. Thanks so much for your videos!

[@DPTubs]

Great idea!!! It’s usually due to color matching Krylon ..because it’s an epoxy…tends to yellow over time….i have switched from using it to only at a minimum

[@kennyd6738]

I’m pretty sure my tub is plastic. It’s in a 94 modular house if I rough it up you think the glass will bond?

It looks bice! No fiber though?

[@cal0214]

I have a construction-special, one-piece shower/tub which has a few small specks of surface missing. Would you use all of this for that, or something else, prior to a reglaze?

[@DPTubs]

No need for foam

[@actualfreedom8]

Great Video. Will fibreglass also work on Acrylic bathtubs?

[@DPTubs]

Yes!

Hi Boss where can I buy that shuff

[@elviagonzalez5605]

Could you provide the waiting/drying times between the different material applications, please? This would be of great help to me. Thank you.

[@DPTubs]

10-15 minutes in between coats or until dry ti sand

[@elviagonzalez5605]

@@DPTubs Got it! Thank you so much!

[@mikes164]

@@DPTubshow long should we wait to use once it’s done?

[@dennisbrown345]

If there is quite a bit of flex what do you recommend?

[@anthonyohare2268]

You can try the spray foam, but if that won't work, hopefully you have access underneath and you will have to mix up & support with structolite or gypcrete or some other lightweight mortar.

[@mistermister124]

Bondo short strand is hard to find

[@rms59]

I wonder why you wouldn't have made the initial hole slightly larger and forced Bondo under the crack instead of foam which I thought would be stronger. Then, why not spray the entire bottom of the tub the same color as the patch which would have made it look uniform? Otherwise.... great video. I feel more comfortable now patching the crack in my tub.

[@kennyd6738]

Because the foam expands pressing upward. Which is why he said he likes to see the foam coming up through the crack that means it’s filled the space beneath and can only go up

[@timrob62]

I cracked the back flange of my fiberglass shower pan while installing it. Since it will be under the tile, I'm not so worried about leaking, but I am worried about the crack spreading. Will Bondo glass prevent that?

[@DPTubs]

Send me a picture

[@joecoughlin9245]

Curious, is the time in the video from beginning of mixing the product until final application of the first coat "actual time" (approximately 1 minute 20 seconds)? Do you immediately pull the tape as soon as first application is done? TIA

[@DPTubs]

No it’s not actual time. Yes I pull the tape around the repair right after first application

[@FunkyColdMedinaDIY]

Great video. Ive seen others use flex seal but I think ill use the bondo glass since it has the fibers in it. Thank you very much and have a blessed day😁

[@CJ-bv2rq]

This is a nice tutorial. How long does it take for the bondo to dry between coats?

[@jasonbaxter5727]

Not my video but I can get you an answer. We use a heat gun to dry the bondo. Which only takes a min. or two. Air drying is significantly longer up to 15-20 mins. at the least. It really depends on the thickness of your bondo layer. Source- I do bathtub repair for a paycheck.

[@gerardocisneros6756]

How long after finished the repair can you use the shower ?

[@steveperez3501]

With that particular paint, an hour or 2. But I would not try washing it for at least a couple days.

[@coldironpower1005]

What happens if someone steps on it while showering? How do you make it a better repair? We did the bondo repair to our old tub (crack was right in middle) and it would keeping cracking every time someone would accidently step on it. We got a new tub about 12 yrs ago and it now that one has a crack in it in the same spot.

[@DPTubs]

Put some fiber mesh tape over the crack like you would a drywall patch then use Bondo glass / then Bondo to smoothen

[@1mondavia2]

I don't have a crack in the tub but a 1-inch, not a deep groove near my faucet on the wall of my tub I would like to fix myself. Can I use this same "Big gap filler" to fill in the groove, then have my whole tub resurfaced? Thanks

[@DPTubs]

Big gap filler is for support underneath. If you want to fill a divot or a chip then use Bondo filler and then reglaze the tub

[@prenderc]

This is really helpful! I just did the Bondo Glass part of the repair. Going to paint next. Why do you use a primer before applying the Rost-Oleum?

[@Krazykidone22]

@dptubs where can i find the music used in the video??

[@waltercade6460]

When should you actually use fiberglass mat?

[@DPTubs]

When the crack is thick and fluctuates. The mat should be used like you would use tape for a drywall seam or crack.

[@cmoore302]

Can this be used on a textured tub?

[@DPTubs]

Yes but the area you repair will be smooth

[@whazzapp]

How long after the patch before you can use the tub?

[@DPTubs]

48 hours to let the top coat dry and cure

[@HolisticallyHealthy-dk1kc]

Where are you located? Would you do a job in Texas?

[@marcusaurelius8717]

You pulling out that aerosol can and painting that at the end just soured the whole video for me. I thought you were going to fix this tub right, but instead done a cheap crappy finish on it.

[@DPTubs]

Actually definitely not crappy …I do this regularly

[@cyrus7210]

Describe a non crappy job for us. Include the various materials and techniques involved. Pros and cons will also be helpful. Lets hear from the soured commenter, not DP Tubs. Being budget minded myself, I've found this invaluable, but any alternative is invited. I'm game to various methods.
