Level Up Your Floors Like a Pro – A Step-by-Step Guide
Got a wonky floor that’s driving you crazy? Whether you’re a builder tackling a new extension, a DIYer renovating your bathroom, or a developer prepping a site for flooring, knowing how to use self-levelling compound will get you a perfectly smooth surface. This stuff is like magic – it flows across your floor, filling in all the dips and bumps to create a flawless base for tiles, vinyl, or whatever flooring you’ve got planned.
But getting it right can be tricky. That’s where we come in. At Capital Screeding, we’ve been supplying and installing self-levelling compounds throughout London, Essex, Kent and the South East for years. We’ve seen it all, and we’re here to share our expert knowledge on how to use self-levelling compound to achieve a professional finish, even if you’re a first timer.
In this guide, we’ll walk you through the process step-by-step, sharing insider tips along the way.
Is Self-Levelling Compound Right for Your Floor?
Before you jump in, it’s crucial to make sure self-levelling compound is the right choice for your project. These compounds are fantastic for smoothing out minor imperfections, but they’re not designed for major levelling jobs.
Here’s the rule of thumb – If your floor is uneven by more than 5mm, you’ll need a more heavy-duty solution like liquid screed or traditional screed.
How to check your floor:
Thankfully, there’s an easy way to check if your floor falls within the limits of self-levelling compound.
- Find the dips – Grab some marbles or smooth ball bearings. Drop them in various places on your floor. This will quickly show you where the floor dips the most.
- Measure the dip – Take a spirit level and place at the edge of the deepest dip you found. Lift the other end until the bubble is in the middle of the spirit level. Then, use a ruler to measure the gap between the spirit level and the floor. If it’s more than 5mm, you’ll need to find an alternative way to level your floor.

Get Hands-On – Applying Your Self-Levelling Compound
Alright, so you’ve checked your floor and you’re good to go with self-levelling compound. Now, let’s get down to business! Follow these simple steps to achieve a perfectly smooth surface:
Step 1 – Prep the Substrate
Before you even think about cracking open that bag of compound, you need to give your floor some TLC. This is crucial for ensuring the compound bonds properly and you get a long-lasting, flawless finish.
Here’s the prep checklist:
- Clean it up - Get rid of any dust, dirt, debris, or loose bits. Give the floor a good sweep or vacuum.
- Patch it up - See any cracks or holes? Fill them in with a suitable filler and let it dry completely.
- Grind it down (if needed) - If you're working with a concrete subfloor, you might need to grind it down to expose the aggregates. This helps the compound to grip.
- Prime time - Priming helps the self-levelling compound stick properly to the subfloor. Check the instructions on your chosen compound - it'll recommend a specific primer.
Step 2 – Mix It Up
Time to mix your self-levelling compound. Grab a clean bucket and a powerful drill with a mixing paddle attachment. Pour the required amount of cold, clean water into the bucket (check the instructions on your compound for the exact water-to-powder ratio).
Gradually add the powder to the water while mixing with the drill. Keep mixing until you achieve a smooth, lump-free consistency, similar to thick pancake batter. Once mixed, let the compound rest for a few minutes to allow any air bubbles to escape.
Pro Tip: Mix only as much compound as you can use within the time it remains workable. This is usually around 30 minutes but check the manufacturer’s instructions.
Step 3 – Precision Pouring
With your compound perfectly mixed, it’s time to pour!
- Start from the back – Begin pouring at the furthest point from the room’s entrance. This way, you won’t trap yourself in a corner!
- Work in sections – Pour the compound in manageable sections, aiming for a consistent depth. Remember that self-levelling compound does what it says on the tin – it levels itself out!
- Spread it out – Use a steel trowel to help guide the compound and ensure an even spread. Don’t overwork it, just gently encourage it to flow into all the areas.
- Remove air bubbles – Once poured, go over the area with a spiked roller. This gets rid of any trapped air bubbles that could weaken the finished surface.
Pro Tip: If you’re working in a large area, have someone help you with the pouring. This ensures a continuous flow and prevents the compound from starting to set before you’ve finished.
Step 4 – Letting it Dry
Drying time varies depending on the specific product you’ve used and the depth of the application. You’ll be able to walk on the surface in as little as 1-8 hours, but it’s important to be patient and let it cure completely. Avoid any temptation to rush the process!
To ensure a perfect finish, keep the area well-ventilated and at a temperature of around 20o C but avoid strong drafts or direct sunlight. These can cause the compound to dry too quickly, leading to cracks and an uneven surface. It’s best to keep foot traffic to a minimum during the initial drying period and follow the manufacturer’s instructions for recommended curing times before installing your final flooring.
