MicroCement application on a external corner


New Member
Can anyone help me please

I bought a microcement kit from www.latiendadelmicrocemento.com

They have youtube step by step videos showing how to applicate, Great!. The problem I have is I need to do an external corner and a recess in shower and unaware of how to do it.

Ive been to two microcement shops now and have asked them how to apply microcement in these particular places. They seem to get the walls plastered first with normal metal corner bead and have shown me a technique with the trowel to completely cover the metal bead.

Is this the only way to do it with out getting the shower area plastered ?
