I’ve watched the YouTube film (a dozen times), sucked up every tidbit on all the DIY forums like an over-enthusiastic Dyson and read the packet labels till the letters all merged together to form the word ‘loser’. Self-levelling compound here we come!
According to YouTube DIY experts begin your flooring fantasy by removing every speck of dust. I’ve hoovered the floor almost every day since last Tuesday so if there’s anything left on it then it’s likely to be an invisible Covid germ or a microscopic grain only detectable with a high-powered telescope.
Next apply primer. So many to choose from but from what I can gather, pick the type that’s most suitable for the type of substrate you’re going to apply the compound to. I’m using one called Larsen acrylic primer which can be used to prime concrete or screed.

The primer is applied in two coats. The first coat is a diluted one – one part water to one part primer. On a small area like our toilet floor even 400 ml of primer is way too much liquid. A litre bottle goes a long way so no ‘range’ anxiety about whether you’ll run out half way through the job.

The second coat is also primer but applied neat. Larsen acrylic primer is like flooring Pepto Bismol, a bright pink colour and can be easily applied using a paint brush or roller. Leave this to dry completely before putting the compound on top.

Time to mix up the compound. Using a 20kg bag of L12 no nonsense self-smoothing leveller from Screwfix. According to feedback on their website, this stuff is the mutts nuts. Let’s hope so!

I really hope this works |
To mix the compound, you’ll need a super-sized plasterer’s bucket and a gadget that looks like a giant whisk which can be attached to an ordinary electric drill.

Woo hoo! Who thought making giant mud pies in a bucket could be so much fun? Make sure you closely follow the ‘recipe’ on the back of the packet as adding too much or too little water could affect your mixture.

When your compound is ready, gently pour over the floor and using a flooring trowel, help the liquid mixture towards the edges. Being a feeble wuss with a bad neck, engage the services of a strong person to lift the bucket then use a large measuring jug so you don’t pour it all in at once.
 |
Ease gently towards the edges |
I was surprised to note how smoothly the compound naturally seemed to gravitate towards the edges of the room with minimal effort from my wielding a trowel the size of a skateboard. Easy does it girl, don’t get too cocky now….
No time for dawdling as this stuff goes off fairly quickly. Start from the furthest wall then work backwards to the door. Ooops! I forgot to mention that you need to chock up the doorway beforehand to prevent anything seeping out under the carpet. Yeah. Do this before you get started or else you might end up with a right mess.

Lovely mirror shine |
Once all the compound is lying across the floor like a grey mirrored lake, grab your spiked roller. Run this carefully across the surface to bring up all the air bubbles.

Now stand back, admire your handiwork then use the rest of the day to bake a real cake to go with a nice brew.
