Thank you. I had a few cracks. One was bad. I followed your instruction exactly and it looks amazing. The floor of the tub is now very solid and the paint from Krylon (Buscuit color) matched up perfectly. Also replaced all of the chromed shower parts and it looks like a brand new shower. I am shocked at how well it worked out for us. Thank you. This video saved me thousands of dollars on a shower/tub insert replacement. Thank you

[@jermainefant2027]

I want to say THANK YOU VERY MUCH SIR for this video!!! My aged parents had someone come out to give an estimate of why the tub was leaking. They were quoted $3000 plus to repair and $8000 to replace. My parents are on a fixed budget. I went to visit (I live 4hrs away) and inspect it myself. No water marks or stains around the fixtures. None where my dad said water was coming out the wall. I noticed a crack in the tub. I watched your STEP BY STEP video about five or six times to build my confidence to see if I would attempt the repair!! THANK YOU again because I did, and it came out perfect!!! Can't tell a crack was even there to begin with. It also fixed the water leak!!!! Thank God for people like you to help people like me and my parents not to be taken advantage of!! HUGE THUMBS UP!!! THANK YOU AGAIN! Your awesome!!

[@magicone9327]

Would it be better to countersink those holes, then the fill would have land area giving more structural to the hole . A straight hole can more easily fail by falling straight through where a chamfered hole hole has a larger top and cannot fall through.

[@DPTubs]

@@magicone9327 nope!

[@cavemanjoe7972]

@@magicone9327 While that's true when it comes to fastening softwoods and aluminum, this application forces epoxy through the hole(s) and cracks as well as bonding with surrounding epoxy and the fiberglass, making a very strong bond.

[@rickonethousand6304]

$3000! ...$8000! People are insane nowadays. They just tell you anything like money is water. I asked about taking a tree down in my yard and they said $3000. It was three guys and they said it would take a day. They were from Honduras and couldn't speak English. I'm pretty sure they must be here illegally. $3000 is probably more than a years salary for 2 people there. I found a local American guy and his son to do it for $600.

So I’m about to apply the smoothing putty to my tub! I have followed all of your steps so far and it’s actually working!!! I’m so excited I will be able to take a bath again soon!!! Mine looks like yours so far, I’m feeling good about it! Thanks so much, my beautiful whirlpool tub is all tiled in and we were not wanting to tear it out. Thanks for sharing your trade secrets!!

Honestly I watch all yalls channels and enjoy them. I also watch(listen) to these channels where the person tells "ghost" "true" "internet" "scary" stories and u have the voice that is so captivating.

[@stonefox60]

I have a fiberglass tub with stress cracks, I called someone local ( I live in NJ) and they wanted over $800 to repair. I watched your video multiple times and did the job myself over the weekend. I could have sanded the putty better, but I am really pleased with the results! Not only did I repair the cracks, but after watching your video I also removed and re-calked the tub - looks brand new!!! Fingers crossed I did it right, and no leaks lol!!!

[@DPTubs]

This is awesome! So glad you found the video useful! Once al material dries...fill the bathtub up and plug it. Let the water sit for about an hour keeping an eye on it and see if the water level changes or if it leaks. This will help you know right away. You could also stand in it while filled to make sure there are no cracks that open up while the weight of a person is in the tub. Otherwise, congrats!!!

[@steverone7623]

How did it hold up one year later?

[@NaffyD92]

Wanted to say thanks along with everyone else. Just bought a house and really don’t have much of a “safety net” for repairs on things. Our tub was sketchy when we first moved in and we noticed a lot of give in areas. After about 6 months a small crack appeared in the floor. This video helped me save a ton and taught me a new life skill. The job wasn’t pretty….but I fixed the sagging floor based off your videos and patched the many stress fractures in the base of the tub and a large crack on the sidewall. Primer is drying over night and then I’ll sand and use the krylon from the video. Thank you so much for willingly showing this process on here for those of us daring enough to try our hands at it. You’re a modern day hero.

[@evaseibert3994]

Wow! I've watch so many other tub repair videos trying to understand this process. This is the absolute best video I've seen. Thank you for your excellent instruction and step by step details. You have given me the confidence to try repairing a small crack in my shower. Thank you many times over.

[@DPTubs]

Thank you so much! So glad I could help! Let me know if you have any questions along the way!

So glad to hear and glad I could help!

[@chgtf6q]

Thank you very much Sir! After drilling the holes, I filled the underside with Locktite Titebond low expansion foam. Definitely made the difference; no movement now. Followed everything else you outlined to a tee. Saved me $1000.

[@sanctidebellum2823]

Thank you so much. Easy job. Took me 3 hours and it looks beautiful. Keep those vids coming.

[@barneslawntree4877]

Thanks for this video! After 5 plumbers, one finally discovered a crack in the tub about 3-4 inches across in the bottom corner. They told me that repairing the crack is only a temporary “band aid”. I was told a new $4,800 tub/shower needed to be put in. Well......I know how strong Bondo is and when I seen this video, I knew right away this was an excellent option. I followed your vid exactly and stayed under $100 buying all the supplies. I’m about 14 hours away from filling the tub and testing out the repair. Only trouble I had was the fact I didn’t have a flexible tool to spread the glass and putty over the curve. I did what I could and smoothed it out with the back of my finger. It wasn’t a super flat flush finish, but after liberal sanding it is smooth and almost unnoticeable after the paint. Thanks for this vid and saving me loads of money. 👍👌😎

[@DPTubs]

So awesome! You can get the rubber Bondo putty spreader at Home Depot

[@slatsgrobneck7515]

Smart Choice to do the repair! I take plumbing advice from plumbers, but not electrical advice or home repairs advice, among others.... lol

[@RisenPhoenix]

I was looking for a repair guide to get my tub fixed in my apartment before I moved out - this is super detailed and shows exactly what products I need to get and how to use them. Thank you so much for sharing this with us!

[@DPTubs]

RisenPhoenix you’re welcome! Thanks for watching!

[@slatsgrobneck7515]

RisenPhoenix, I realize this comment is 7 months after the fact, however, I hope you got the Ok from the owner/lessor before attempting that repair. It is perhaps a violation of the terms of your lease. Also as a rental owner, doing my own maintenance work, I would not want to have someone leave behind a substandard repair that I would have to address before I could even tackle the real repair.

[@solargarden0919]

Excellent video. Gave me a real clear understand of how to properly lay fibreglass repairs down for an emergency stop gap solution until we Reno the bathroom. Probably won’t bondo/ putty as aesthetics aren’t super important on my repair but still a super helpful video

[@MrPhoenix1800]

Thank you for posting this, you can tell that you have done this a lot. I bought everything you used in this video. I am on the step two in the bondo glass. It has turned out really really good so far. I can’t wait to see the end product when I am done. I had to pay a plumber 460.00 for some plumbing issues and it’s been hard financially for me and my wife and three kids, this video really helped me. Thank you!

[@DPTubs]

So glad to hear that!! Shoot any questions that you may have! How did the brushing of the cloth go with the resin?

[@MrPhoenix1800]

Because my crack was on the side I did not realize that gravity would pull the resin down, so it was a little thicker on the bottom of the tub so I had some sanding to do but I just put the primer on today and have the tub and tile shipping tomorrow and will be done.

[@DPTubs]

derek meese did you brush the resin on?

[@janelleoutram1928]

This video saved tub. Got the resin, fiberglass mat and the Bondo all purpose putty in grey and followed your steps. I need to find that primer and paint to color match now. I have 2 bathrooms so it allow me to max out setting times. I literally gave each step 24 hours to set because I notice that room temp is a factor. It’s officially autumn in Los Angeles so the colder it is the more setting time you need. Amateur tip: A small sander, space heater and box fan come in handy for this job.

First off, I can't express how thankful I am for this tutorial!! I was quoted 12k & 16k to just replace my tub , completely covering up my custom tile. I was adamant about figuring out how to fix my tub myself at that point. I'm at the step of sanding right before the putty part and wanted to know if this sanding part I needed to sand until smooth?

[@BambiCole]

Danny it is fascinating to watch you do these repairs. I don't know if I heard this before or not so, I am wondering what got you started? How did you learn? How long have you been doing it? How long have you had your own business? Do you do commercial properties as well as residential? Yes, just call me nosey. This has come out beautifully. I am glad your working in spite of what's been going on. Thank you so much for sharing.
