Step to Follow on How to Fix a Dip in a Bathtub

Step One: Determine

First of all, you’ve got to decide whether or not the dip in your bathtub is severe. Then, gather everyone in the house and see what they think. If anyone says it’s crucial that whatever must be done is done right away, you know that the situation is serious.

If there’s something broken that you’re not sure if you should fix right away or not, you can wait and see what other people think. If most people think it can wait, then it’s probably not a big deal and you can fix it later. But if most people think it should be fixed right away, then you should too.

That’s probably the best way to go about things in life – don’t get your way all the time, because if everyone did everything they wanted whenever they wanted to do it, then life as we know it would be a chaotic mess.

Step Two: Mark the Spot

If there’s a problem with something in your house, you should first decide if it’s serious. If it is, use a piece of chalk to mark the spot. Make sure to use enough chalk so that the problem can be fixed completely. If there’s still some room on the wall, make another mark next to it and choose which one looks like it would be easier to fix.

If you think the spot is slightly off-center on the bathtub, mark both where and where you think it should be. This way, if there’s a difference of opinion about how to go about fixing this problem, you can at least agree on which one of the two should be.

If you can’t tell which answer is right because the mark is in the middle or exactly where it should be, then use your best judgment to decide which one to mark. Just be careful not to make a mistake if you already made a mistake and marked the wrong side.

Step Three: Fill in the Hole

Fill in the hole with spackling paste. Use a dabbing motion when you apply it to don’t have too much paste on any one spot. This will ensure that you can smooth out all of the ridges when applying them to your bathtub and that the patch won’t look bumpy or uneven.

Getting rid of spackling paste from the bathroom floor is simpler than it seems. Oftentimes, you can wipe it up without difficulty, but if you’ve put on several layers of the stuff and your bathtub is no longer level with the wall, then you might have to wait until all those layers dry before you can take any action.

Step Five: Let It Dry

The spackling paste was designed to even out the color, but it can end up looking slightly off if you’re not careful about how much you apply. So, after it dries overnight, you might want to sand down any spots that got extra dark with fine-grit sandpaper before applying your spackle.
