Does self-levelling compound need a spiked roller?

It is better to have a spiked roller in your arsenal when laying self levelling compound. Spiked rollers are moved across the surface to release tiny air bubbles trapped in the self-levelling compound.

When you mix your self-levelling compound with a whisk or a mixer it can add air bubbles. The problem is, once you have started to pour your self-levelling compound you can’t stop. If you see any air bubbles in your mix and you don’t have a spiked roller to hand, it’s too late.

Alongside a decent trowel, Spiked rollers can also help to spread the self-levelling compound around a little bit.

With a decent trowel, a spiked roller and a whisk you give yourself the best possible chance of getting successful results! It’s the exact same gear the Professionals use.

I have done many floors myself using Ardex Na self-levelling and managed to get away without a spiked roller. But I have always seen one or two air bubbles set in the finished pour. I have always managed to hide them with the finished floor covering. But If I need to do another self-levelling flooring job, I will be investing in one, in order to get the best possible results. But the choice is yours!

What is self levelling compound?

Self-levelling compound is also known as a floor screed or floor levelling mix. It is a thin layer of a cement-based mixture that is applied to subfloors in order to level out any bumps.

The mix is applied in a thin layer to subfloors such as concrete and floorboards, you use it before laying another floor, such as tile, above it.

It is called a self-levelling compound as it, in theory, self-levels. What this means is that you don’t have to worry about getting the mix perfectly level. It should flow across the floor, and correct any errors.

While this does generally work, there are limits. It doesn’t flow like water so will not perfectly level over a large area and may require a bit of help from you.

Why use self-levelling compound?

You use a self-levelling compound to turn a bumpy, un-even subfloor into a perfectly smooth surface. This is great when you are fitting a solid floor such as tile or wood.

Your floor wont be able to hide the bumps and just sit on them when you fit a rigid floor. Tiles will crack and break and a wood floor will bounce and move. Whereas a flooring like carpet will happily sit on an uneven base.
