Questions & Answers


The gelcoat repair kit does it have everything it needs to repair cracks in a white tub

Asked by JP January 5, 2021

Yes, follow instructions and it will work great. Takes a couple of hours to set (cure) before you can sand it.

Will this work on an acrylic bathtub?

Asked by Deb November 29, 2020

The patch works but not color

Asked by tubguy September 16, 2020

It is available in BONE. At the end of the part number, exchange the "WH" to "BO"

I put too much on. How can I remove the excess? I put way too much on and it is clunky.

Asked by Ursula August 6, 2020

Use the sand paper to smooth it out!!

Will this product work over rust?

Asked by kyle May 11, 2020

I didn’t get to use it because it was hard in the container. Horrible experience. I made a trip to get it and couldn’t find it in location that the website said. No one knew where it was. Went back and found it hanging by tubs. Know I have to make another trip to return.

Does this work to repair home in fiberglass tub?

Asked by KTC October 29, 2019

It works great if the crack is not too big. Over an 1/8 inch wide is not real good.

I have worn the finish of my new shower! I cleaned with a bathroom spray cleaner and scubbie. What will restore the finish?

Asked by Linda July 20, 2019

It is not made for large areas.

My tub is leaking thru a small hole. Will this fix it ?

Asked by Szabs June 2, 2019

Hello, This kit is designed for the DIY'er for small repairs. If your tub is out of it's warranty period you can make this home repair successful by taking specific steps. You can ensure a good repair by prepping the area per the instrutions in the kit. Lightly sanding then cleaning the are up with rubbing alcohol and making sure it is dry before applying repair product will make for a better bond. Good luck with your project.

can this cover a 1 inch by 12 inch gouge in boat under water line?

Asked by JOHN April 4, 2019

You need a fiberglass repair kit for something that big. This is not made for large areas.

How long do you have to wait after repair to use shower

Asked by FrombeHinz December 12, 2018

I waited 24 hours to be one the safe side

The product works as advertised. Make sure the area to repair is cleaned out and below the surface around it. If you are attempting to repair spider cracks, use a file or rough sandpaper to create a depression to build up. Depending on the repair, you may need to use more than one application of the filler. There is an ample supply of the filler. I found that using a rubber spatula to spread the product works well. It will clean up with rubbing alcohol and your wife won't suspect a thing. I allowed the product to dry over night before sanding. The product odor isn't that bad, but make sure you have adequate ventilation during the process. A painter's mask will help. Nitrile gloves are also recommended. As far as the other supplies in the kit, they are not sufficient in quantity relevant to the amount of filler. Do yourself a favor and purchase extra 400 and 600 grit wet sandpaper as well as rubbing compound to polish out the scratches. Have a bottle of rubbing alcohol on hand as well. When the repair is dry and you are ready to sand it smooth, keep the surface wet. The sandpaper works much better and will reduce the effort needed. That is not to say that it won't take time. Be patient. Although the product is white, don't be alarmed if it is not a perfect match. Most repairs are done on older surfaces where the color has faded over time plus the cleaning chemicals used will have faded the finish. When you are all done and happy with the repair, use a good quality car wax to keep the finish shiny and for ease of cleaning. If it is a tub, do not wax the standing/sitting surface as to prevent slips and falls. This will help reduce soap buildup.

Easy to apply, instructions were great. I only gave it 3 stars because the color did not match even though it is from the same manufacture which built the shower enclosure.

I needed to repair a small hole in fiberglass tub....dropped a screwdriver point down, naturally...the mixing instructions for the two components were a bit vague for such a small amount, but the paste eventually set up after two days...the rough patch sanded smooth with the included wet sandpaper. As you can see in the photo, I wasn't too fussy about matching the nonslip texture of the tub bottom but I don't notice the patch. The picture shows patch at end of screw driver...

Pretty simple repair on three dents (one was pretty much a small hole) in the kids’ tub. Watch a few YouTube videos if you’re doing this for the first time. They helped me know what to expect. The mixing and filling was pretty straightforward, but I felt like I may never finish sanding! Getting it even to the existing surface was challenging. Make sure you overfill the repair a bit due to shrinkage while the material hardens, keep the sandpaper wet, and avoid sanding outside the repair area. The attached image is damage, repair in progress, and finished product.

Our tub is 50 years old. It had a couple dings and bad spots. I was dabbing white acrylic paint on it, but it didn't last long. I thought maybe we should get it replaced. With the new tub, labor, plumbing, fixtures, mess, etc.....bottom line estimate was about $1500. I thought, what the heck? For $20 this was worth a try. It actually was really easy to apply and the directions are good. It's been about a month now. If you stand back, you don't notice the color difference. You really need to get right up to it to see it. The pictures show what was a fist size bad spot on the curve of the tube. The rest of it was just small dings. Use in a really well-ventilated area. The smell doesn't last real long, but it is very strong.

Laundry/Utility Tub
Accidentally punched a hole in my laundry/utility sink. I followed the directions, mixed it thoroughly, and it did a great job. It's only a utility tub, so I really didn't mind that the color didn't match.

Worked great!
I fixed a pretty large whole (about an inch round) using this product and it did the job. Of course, you are never going to get it perfect but from a distance you can't even tell there was a whole there. I could have sanded more but it seems to take forever.

Solved my problem
I had a tub/shower that had developed a crack in the curve of the side / bottom. By following the instructions this product sealed the crack and undoubtedly kept me from having to purchase a new tub and pay a plumber to install (since I'm quite sure installing a new tub / shower enclosure is beyond me). I was very careful to mix the paste and hardener thoroughly, and let it set up for 24 hours before sanding. After 24 hours it was rock-hard.
