How to Get Rid of Ridges in Self-Levelling Compound

As a professional floor layer, I’ve seen it all when it comes to self-levelling compounds. And one of the most common issues I see is ridges in the surface. It’s not just unsightly, it can also lead to tripping hazards and reduced durability of the flooring.

In this article, I’ll walk you through the best practices for getting rid of ridges in self-levelling compound, so you can achieve a smooth, level surface that lasts. So, without further ado, let’s get rid of those pesky ridges!

Most Common Cause of Ridges

Every time you pour a bucket of self-levelling compound and spread it with a trowel it can create ridges. If you go through the self-levelling compound with a spiked roller while it is still wet blends the self-levelling compound together and eliminates this problem.

Step 1: Identify the source of the problem

The first step in getting rid of ridges in self-levelling compound is to identify the source of the problem. Is it because you applied the compound too thick in some areas, or because the surface wasn’t properly prepared? These are just a few examples of why ridges can occur, and it’s important to determine the root cause before moving on to the next step.

Step 2: Sand down the ridges

Once you’ve figured out what’s causing the ridges, it’s time to start fixing them! If the ridges are not too high, you can use a sanding block to gently sand them down until they’re level with the rest of the surface. Just be careful not to sand too much, or you’ll end up creating even more ridges!

Step 3: Apply a new layer of self-levelling compound

If the ridges are too high to be sanded down, or if you’ve sanded down too much, it’s time to apply a new layer of self-levelling compound. Make sure to follow the manufacturer’s instructions carefully, as the process may vary depending on the product you’re using.

Best Solution for Ridges

Use an angle grinder with a diamond disc to grind down the ridge or re-pour a thin layer of self-levelling compound over the top. Use a spiked roller to distribute the self-levelling compound evenly over the surface

Step 4: Finish it off

Finally, once the new layer of self-levelling compound has been applied and has had time to set, it’s time to finish the surface. Depending on the look you’re going for, you can apply a coat of paint, or even lay down some tiles or carpet. Just make sure to let the surface fully dry and cure before applying any other materials.

And there you have it! Four easy steps to get rid of ridges in self-levelling compound. Of course, the process may not always be as straightforward as this, but with a little patience and a lot of elbow grease, you’ll be able to get rid of those pesky ridges in no time.

Just remember, if at first you don’t succeed, try, try again! (And if all else fails, you can always call in a professional flooring expert.)
