A Complete Guide On Fixing Hairline Crack In Fiberglass Tub
There is no denying the durability and cost-effectiveness of a fiberglass bathtub, but we cannot make the unrealistic assumption that it will never get defected in one way or the other. The most common defect that may occur in a fiberglass bathtub, is a crack. Such a defect may be caused by improper installation, overuse of the bathtub, or accidents.
A crack in a fiberglass bathtub will only progress once it has emerged.
Another problem that a leaking crack can cause is, ceiling leakage for the people who live below you, if you live in an apartment complex. Needless to say, if you see a crack in your fiberglass bathtub, it is time to get down to the fundamentals. You may be told that your only option is to replace your bathtub altogether, or hire a plumber.
Both of these options can be quite costly, so if you want to refrain from them, we have good news for you. There is a way for you to fix that unsightly crack all by yourself! Here is a step by step guide for how to fix a hairline crack in a fiberglass bathtub:
Step 1: Cleaning
- Bathroom cleaner
The first step of the process is the most crucial one, cleaning your bathtub is absolutely necessary if you want to fix that hairline crack once and for all. Start off by draining your bathtub of any water that may be in there. Fill up a bucket of water, and pour an adequate amount of the bathroom cleaner in the water. Soak the sponge into this mixture, and begin scrubbing your bathtub.
Make sure every part of the bathtub is scrubbed, because failure to do so may cause you to overlook other cracks, if there are any. Once you are done scrubbing, rinse the bathtub and drain the water again. The bathtub needs to be completely ridded of water.
Step 2: Checking the severity of the crack
- Measure tape (optional)
Although this step can be carried out without having to use a measure tape, it is better if you use it anyways as it will ensure accuracy. Measure the width of the crack, if it is more than 4 inches wide/long, you will need to cover both of the outer sides of the crack by using fiberglass mesh tape. This is done to make sure that you do not end up spreading the fillers in unaffected areas which may be used in the next step, depending on whether or not your crack is deep enough to be filled.
To check the depth of the crack, try to insert your measure tape in to the crack gently. If it goes in, your crack needs filling. If it stays at the surface and does not slide into the crack, you only need to smoothen the crack.
Step 3: Fill and smoothen
- Fiberglass filler
- 240 grit sandpaper and 800 grit sandpaper
- Rubbing alcohol
Part 1: Filling
This step is only required if the bathtub crack is deep enough, which you can determine by carrying out the experiment we elaborated in step 2. Drill a small hole at each end of the crack, drill at your driller’s lowest setting. Make sure you do not drill all the way to the other side of the bathtub. The hole only needs to be drilled halfway. Fill both of the holes with the fiberglass filler, and let dry.
Part 2: Smoothen
This step is required for a deep crack and a slight crack as well. If the crack in your bathtub is not deep enough, or even if it is, you have to carry out this step. If you carried out the filling step, make sure the fiberglass filler present in the holes is completely dry before you begin this step. Rub the 240 grit sandpaper over the crack and filled areas, gently and in a circular position.
If you overexert pressure, the filling may get ruined or the surface of your bathtub may get scraped and rough. Finish off the smoothening process by using the 800 grit sandpaper in the same way. Once the formerly cracked area is fully smoothened, rub a few drops of rubbing alcohol all over it to eliminate dustiness.
Step 4: Painting
- Repair paint
After the smoothening process is completed, you will need to paint the previously cracked area with repair paint. This type of paint is available in a spray version and also a brush paint version. Make sure you buy it in a shade which matches the shade of your fiberglass bathtub, because the whole point of using this repair paint is so the fixed area can blend in with the rest of the bathtub. Paint the fixed area with two coats of the repair paint, and let dry. Once the paint is fully dry, repeat the cleaning process again so that your bathtub is clean enough for use.
