Can you Sand Self levelling Compound?

In this article, you’ll gain a comprehensive understanding of whether or not you can sand self-levelling compound and what alternative methods are available for removing excess material.

As someone with experience using self-levelling compound, I often get asked “can I sand self-levelling compound?” The short answer is yes, you can sand anything when you come to think of it. The question is a matter of how effective it will be.

It is normally only worth sanding self-levelling compound in small areas. However, it is important to note that there are other ways to remove excess self-levelling compound that may be more effective and efficient.


You can only sand self-levelling compound using a very abrasive disk to remove small imperfections, over a small area. Grinding is a better option in most cases

Sanding Self-Levelling Compound

When sanding self-levelling compound, it is important to use the right tools and techniques. You will need coarse-grit sandpaper (such as 60-grit) and a sanding block. A sanding block helps ensure that you apply even pressure and create a smooth surface.

Start by sanding the surface in a circular motion, taking care not to sand too aggressively as this could damage the underlying material. As you sand, you will see the excess compound start to break down and disappear. It is important to keep sanding until the surface is smooth and free of any rough spots.

Having a vacuum cleaner handy can really help you to keep the dust down. Once you have finished sanding, you should clean the surface thoroughly to remove any dust or debris. This will help ensure that the final surface is smooth and even.


Grinding is a far better way to remove ridges, high spots or stones that may be trapped in the self-levelling compound. This can be done on a smaller scale with a diamond angle grinder disk and a vacuum.

Alternative Methods to Remove Excess Self-Levelling Compound

While sanding is an effective way to remove excess self-levelling compound, there are other methods that you may find easier or more efficient. These include:

  • Scraping: If you have a large area of excess compound, you may find it easier to remove it using a scraper. A scraper allows you to remove a large amount of material quickly and efficiently.
  • Chiselling: If you have a small area of excess compound, you can use an old wood chisel or a masonry cold chisel to carefully chip it away. This method is particularly useful if the excess compound is in a tight or hard-to-reach area.
  • Wiping: If the excess compound is still wet, you can wipe it away with a damp cloth. This method is most effective if you catch the excess compound before it has fully cured.


Most people forget you can actually re-pour a thin layer of self-levelling compound over the surface to smooth it out. Doing a double pour is sometimes recommended when you need to apply a thick layer.

Regardless of the method you choose, it is important to be patient and take your time. Removing excess self-levelling compound is a delicate process, and rushing can result in a poorly finished surface.

In conclusion, sanding self-levelling compound is an effective way to remove excess material, but there are other methods that may be more suitable for your needs. Whether you choose to sand, scrape, cut, or wipe, the key is to be patient and take your time to ensure a smooth and even final surface.
