Tadelakt is a Moroccan lime plaster that is polished with stones and sealed with soap, so it can line a shower or tub with one seamless surface and no grout.
Quick answer: Tadelakt is a water-resistant lime plaster that comes from Morocco, where it has lined baths for centuries. It is troweled on, then compressed and polished by hand with smooth stones. While it is still damp, it is rubbed with black olive soap. The soap reacts with the lime and helps seal the surface against water.

The result is one smooth, soft-sheen surface with no grout lines. There is nothing to crack, stain, or grow mildew between tiles. It can curve around a niche, a bench, or the edge of a tub without a single seam.
Tadelakt is slow, careful work. Each section has to be compressed at just the right moment as it firms up. Rush it or wait too long and it will not seal. That is why, as a Tadelakt installer in Houston, Antonio lays every Tadelakt wall himself.

Tadelakt is not forgiving. The plaster has to be polished at the exact moment it firms up, and the soap has to go on while it is still damp. Miss the window and the wall will not resist water. Antonio is a certified plaster specialist and lays every Tadelakt wall himself, because this is not a job you learn on a customer's shower.
Yes, it is water-resistant enough to line a shower. Tadelakt is lime plaster that is compressed hard with stones and sealed with black olive soap. The soap reacts with the lime to help shed water. It is seamless, so there is no grout to crack or grow mildew. It still needs a proper waterproof backing behind it.
Yes. Showers and tub surrounds are what Tadelakt was made for. It can cover walls, curve into niches, and wrap a bench with one smooth surface. Shower floors take extra care and a very solid base, so Antonio will look at your space and tell you honestly where it fits best.
Clean Tadelakt with a soft cloth and a mild natural soap, like black soap. Rinse and let it dry. Do not use bleach, vinegar, acid cleaners, or scouring pads. They eat into the lime and strip the soap layer that protects it. A light coat of black soap or wax now and then keeps it sealed.
Fine hairline cracks can happen, as with any plaster, but they are rare when the base is solid. Most cracks come from a wall that moves or a backing that was not built right. We prepare a stable, waterproof base before any plaster goes on. Small marks can often be polished out later.
Tadelakt can last for decades when it is laid well and cared for. Lime keeps hardening as it ages, so the surface gets tougher over time. The main thing is gentle cleaning and a fresh rub of soap or wax every so often. Harsh cleaners are what wear it out early.
It depends on what you want. Tadelakt gives you one seamless, soft-sheen surface with no grout lines to clean, crack, or grow mildew. Tile is harder and takes more abuse. Tadelakt needs gentler cleaning and usually costs more, because it is all hand work. Many people choose it for the look and the calm of no grout.
Black soap is a soft soap made from olive oil, used to seal Tadelakt. It is rubbed into the plaster while it is still damp. The soap reacts with the lime and forms a water-shedding layer. It is also what you use to clean and refresh Tadelakt later, so the same product protects it for life.
