Step 1: Check Out The Problem

To solve any issue, you need to check it out first. If you don’t know what you’re dealing with, how will you ever be able to solve the issue?

At first, check out if the compound is too soft or not. Can you make a fingernail mark in it?

If it seems that much soft, you should remove it all and start it all over again. You’ll have a steady surface than to work with then.

Step 2: Sand The Floor

If you have an uneven floor, you need to sand the floor. And you can use the orbital sander to sand the floor in that case.

You need to wear the mask, gloves, and goggles before you start the sanding. You see, sanding the floor will create a lot of dust. So, you need to protect yourself from inhaling those.

You can also use a simple trick like spraying some water on the floor to save yourself from the dust. Because the water makes the dust heavy and stops it to float around in the air.

Step 3: Get Rid Of The Bad Compound

Not-so-level parts of the compound can be a form of the self leveling compound mistake.

So, if you’re looking to get rid of that not-so level parts of the compound, you can try chiseling them to be almost level with the ground.

Then, to get it down, you can use the orbital sander and sand it smooth.

However, if you need to remove all of the compounds, you should try breaking up as much of it as possible with a hammer.

Then, you can pick off the remains with a paint scraper. And if you need more heavy-duty tools, feel free to use them.

Your only goal right now is to get rid of as much of the compound as possible. Don’t forget to spray water whenever it’s about to dust.

Step 4: Prepare The New Compound

In most of the cases, people face issues because they didn’t mix their compound properly.

Grab a 20-liter bucket first. Then, pour out the self leveling compound in the bucket.

Now pour water and keep on mixing the whole mixture. Mix it with a stick and mix till the whole mixture becomes as thin as milk.

Don’t let it become thick under any circumstances. Keep pouring water little by little to make it thin.

You’ll need to be ready because you’ll need to apply this compound right after the mixture is ready.

Step 5: Apply The Compound

It’s time for you to start applying the self leveling compound.

You can fill in either the valleys you made in the old compound or the spot where the compound previously was.

You’ll need the paint scraper when you apply the compound. This will help you to apply the compound evenly on the surface. That means a leveled surface is coming up soon.

After you’re done applying the compound, you need to let it sit for some time. We’ll recommend that you wait almost a day for the product to dry completely.

Or else you might need to face the same issue that you had before with the surface.

Step 6: Check The Whole Surface

After the compound is totally set on the affected area, you need to check out the rest of the surface. Look out for any other issues on the surface.

If you notice any other issue similar to this, feel free to use these same steps to get rid of the situation. You’ll soon have a surface that is as good as new.
