can this be applied on a wall interior

Maybe a tilt up

You need to act very fast if pressing into recently applied render; I certainly wouldnt fancy holding the stamp up there too long!

but i see no reson why it cant be done.

of course you can have a moulding made to simply "hang" on the wall but of course it will be in relief, the opposite.

Short answer is Yes but having said that I am not aware if required material is in CM. over the initial cement a "stampable overlay" (google it as common building term) is applied to required depth. This is a special cement mix generally grey or a dry polymer and how faux internal walls are decorated or finished in a rock or repeated fashioned whatever brick shape you want and sometimes painted over. It is generally not carved into as a one of design as is made to be stamped. With the right product after render the stamping itself is a very quick process. Can make a great feature wall and size is not limited.

Ps this is the company I used overseas who apparently export to Thailand

Doing this can add time if it is a new wall as any new cement needs maybe a month to cure before render should be applied.

According to a supplier of stone products that I use in Maejo, "the man who does stamping has gone to Bangkok", make of that what you will.
