Lime Plaster in a Shower

Q Can hydraulic lime be used as a plaster wall about 1/2” thick in an application such as, an indoor shower that will have tile installed over it? If so, then how long should the wall cure before installing the tile? What type of bonding agent should be used? Can lime putty/paste e used to set the tiles to the wall? I am in Arkansas, USA.

A Yes you can…but why tile over it? Hydraulic lime is used for showers, bath and pools in the middle east (where my grandfather trained me). You colour your final layers and polish. Use a soap mix to form a layer of calcium stearate and re polish. This will give you a shower that looks as if formed from a single block of marble in any colour. If you must tile it ..cure time depends on the lime you use. Don’t use lime putty as a adhesive…however I have used hydraulic lime as one and grout for mosaic work.
