New flooring is one of those changes that transforms a whole room, which is exactly why it’s worth not rushing. The single biggest thing that decides whether new tiles or vinyl look good, and stay looking good, isn’t the flooring itself. It’s whether the surface underneath is properly flat before anything goes down.
When planning new floors, remember that most existing floors have a bit of movement in them: shallow dips, small humps, uneven patches where something was repaired years ago. You don’t really notice until you lay something new and rigid over the top. Then a dip leaves a tile unsupported and it cracks, or a hump makes laminate rock and creak every time you walk past. Large tiles and thin luxury vinyl are especially unforgiving, because they show every little unevenness underneath.
This is where self-levelling compounds come in. They’re cement- or gypsum-based mixes you pour over the prepared floor as a liquid; they spread out, settle to a true level and dry to a smooth, hard surface ready for your new flooring. It’s a standard step for flooring professionals and an achievable one for a confident DIYer, and it’s the difference between a floor that lasts and one that disappoints.
If you’re doing it yourself, preparation is everything. Clear and clean the floor, prime it so the compound grips and doesn’t dry too quickly, and check how far out of level things are with a long spirit level first so you buy enough. Mix to the instructions, work in one go because it sets fast, and run a spiked roller over it to knock out any air bubbles as you pour.
The part people get wrong is patience at the end. A compound can feel dry underfoot long before it’s genuinely ready to be covered, and moisture-sensitive floors will suffer later if you rush it. Check the recommended drying time and, if you’re unsure, it’s worth having a tradesperson assess the floor, especially in an older home where the levels can be all over the place.
It’s the least exciting line on any renovation to-do list. It’s also the one that quietly protects everything you spend on the floor above it. Get the base flat and level, and the beautiful new floor you actually chose gets to look its best for years.
