## They solve different problems

A micro-topping follows the existing slab — so flatness depends on the slab being flat. It’s perfect for a refined finish over a sound, level surface. A self-leveling overlay is liquid: it flows out and levels itself, building up where the slab dips and skimming where it doesn’t. Use it when the slab is uneven.

Both are part of the

 family. The choice depends entirely on the slab condition.

## Picking by slab condition

Run a level across your slab. If it’s within 1/8” over most of the floor, micro-topping works. If it dips more than 1/4” in spots, self-leveler is the right call — and may save you from a much larger leveling job.

For some projects we combine both: self-leveler to flatten the slab, then a micro-topping skim coat for the final troweled finish. That gives you a perfectly flat substrate and the texture and color you want on top.

We’ll level-check the slab during the quote and recommend the path that fits your budget and aesthetic goals.

## Frequently Asked Questions

Which is more expensive? +

Self-leveling typically costs more per square foot due to material thickness and labor needed for flow control.

Can they be combined? +

Yes — self-leveler can flatten the slab, then a micro-topping can be troweled on top for the desired finish texture.

Which dries faster? +

Micro-topping. Self-levelers need more cure time before traffic or finishing.
