If you're planning on laying a new floor over an old one, you're probably wondering about the best way to handle egaliseren tegelvloer without making a huge mess of it. It's one of those jobs that sounds intimidating at first—liquid cement, precision leveling, and a ticking clock—but once you get the hang of the prep work, it's actually pretty satisfying. Most people want to skip right to the pretty new floor, but the truth is, your finish is only as good as what's underneath it.
Why you can't just skip the leveling part
You might look at your current tile floor and think it looks "flat enough." Maybe the tiles are mostly straight, and there are just a few bumps here and there. But here's the thing: if you're putting down PVC, laminate, or even new large-format tiles, those tiny imperfections are going to haunt you.
When we talk about egaliseren tegelvloer, we're usually trying to solve two main problems. First, grout lines. Even if your tiles are perfectly level, the grout lines are lower than the tile surface. If you lay a thin floor like click-PVC directly over that, those grout lines will eventually "telegraph" through, showing up as ghostly shadows on your beautiful new floor. Second, old floors often have a slight slope or "lips" where one tile sits higher than the neighbor. Leveling takes care of all of that in one go.
Getting the prep work right
I can't stress this enough: the actual pouring of the leveling compound is about 10% of the job. The other 90% is preparation. If you don't prep properly, the compound won't stick, it'll crack, or it might even start peeling up in a few months. That's a nightmare nobody wants to deal with.
First, you've got to get that floor clean. And I don't just mean a quick sweep. You need to degrease it thoroughly. Old tile floors usually have years of floor wax, soap residue, or kitchen grease built up on them. Use a heavy-duty degreaser and scrub like you mean it. If there are any loose tiles, you need to fix them or remove them and fill the hole. A hollow-sounding tile is a sign that it's not bonded to the subfloor, and if it moves, your new leveling layer will crack.
The secret is in the primer
Once the floor is clean and dry, it's time for the primer. This is the most critical step when you're busy with egaliseren tegelvloer. Since tiles are non-porous (especially glazed ones), a standard primer won't work. You need a specific "non-absorbent" primer, often called a tile-on-tile primer or a "betoncontact."
This stuff is usually a bit gritty—it feels like it has fine sand in it. This creates a "key" or a rough surface for the leveling compound to grab onto. Without it, the compound is just sitting on top of a slippery glass-like surface. Apply it evenly with a roller and let it dry completely until it's tacky or dry to the touch, depending on what the bottle says.
Choosing the right compound
Not all leveling compounds are the same. When you go to the store, look for one specifically rated for "non-absorbent" or "tiled" surfaces. Some are fiber-reinforced, which is great if you think there might be a tiny bit of movement in the floor or if you have underfloor heating.
Also, pay attention to the thickness it can handle. If your floor is really wonky, you might need a compound that can go up to 20mm or 30mm. If it's just to cover grout lines, a thin-coat version is usually fine. Just don't buy the cheapest bag you find; you want something that flows well and has a decent working time.
The gear you'll need
Before you start mixing, make sure you have everything within arm's reach. Once you start pouring, you can't stop to look for a tool. You'll need: * A large mixing bucket (or two, so one person can mix while the other pours). * A heavy-duty drill with a high-quality mixing paddle. * A squeegee or a leveling rake to spread the goop. * A spiked roller (this is non-negotiable for a smooth finish). * Spiked shoes (if you're doing a large area and need to walk into the wet compound).
The spiked roller is the real MVP here. As you roll it over the wet compound, it pops all the little air bubbles and helps the material settle into a perfectly flat sheet. If you skip this, you'll end up with tiny pinholes everywhere.
The mixing process
This is where things get fast-paced. You want a helper if possible. One person stays on "chef duty," measuring water and mixing, while the other handles the pouring and spreading.
Follow the instructions on the bag to the letter. Don't eyeball the water. Too much water makes the compound weak and dusty; too little and it won't flow, leaving you with a lumpy mess. Use a measuring bucket for the water so every batch is identical. Mix it until there are absolutely no lumps—it should look like thick pancake batter.
Pouring and spreading
Start at the furthest corner from the door. Pour the compound in strips and use your squeegee to push it into the corners and spread it out. You don't have to be perfect with the squeegee; the "self-leveling" nature of the product will do a lot of the work for you.
After spreading a section, go over it with the spiked roller. Move it back and forth and side to side. This helps the different pours blend together so you don't see "seams" between buckets. Keep moving quickly. Most compounds start to set within 15 to 20 minutes, and once it starts to get "tacky," stop touching it. If you try to fix a bump once it's half-set, you'll just make it worse.
What about underfloor heating?
If you have underfloor heating, egaliseren tegelvloer requires an extra bit of caution. You need to make sure the heating is turned off at least 48 hours before you start. The floor needs to be at room temperature. If the pipes are warm, the compound will dry too fast and crack like a dry desert floor.
Once you're done, don't turn the heating back on immediately. Give it a few days (usually a week is safest) and then turn it on very slowly—increase the temperature by only a couple of degrees a day.
Drying time and patience
I know you're excited to see the final result, but stay off the floor! Most products say you can walk on them in 3 to 4 hours, but that doesn't mean it's ready for the final flooring. The moisture needs to escape.
If you're laying PVC or laminate, you usually need to wait at least 24 to 48 hours. If you're unsure, a pro tip is to tape a small square of plastic wrap to the floor. If there's condensation under the plastic after 24 hours, it's still too wet.
Common mistakes to avoid
One of the biggest blunders people make when egaliseren tegelvloer is forgetting to seal the edges. Leveling compound is very thin when it's wet—it will find every crack, hole, or gap. If you have a hole where a pipe goes through the floor, the compound will disappear down it. Use some foam strips or even just some painters' tape and caulk to create a "dam" around the edges of the room and any openings.
Another mistake is working in a draft. If you leave the windows open or have a fan blowing, the surface will dry faster than the bottom. This causes tension and leads to surface cracks. Keep the room closed up and at a steady temperature while it's drying.
Is it worth doing yourself?
If you're a confident DIYer, absolutely. It saves a lot of money and the results are incredibly rewarding. There's something therapeutic about watching a rough, ugly tile floor turn into a smooth, grey mirror. Just remember that once the powder hits the water, the clock is ticking.
Take your time with the cleaning and the priming, get a friend to help with the mixing, and don't skimp on the spiked roller. If you do those things, your egaliseren tegelvloer project will be a total success, and your new floor will look like it was installed by a professional. Now, go grab a bucket and get started!
