We have a tiled floor but they are old and don't look very good. We are thinking of going polished concrete but how do we get all the glue off and do we have to pour new concrete on top of the mess that will be underneath the tiles?

Usually this is not required, once the tiles have been removed the remaining glue and mess can be ground to a brand new surface. However there can be exceptions.

Can the slab be heated?

Yes, any slab can be heated. With in-slab hydronic heating on a polished concrete you will never live on a better floor.

Should I add retarding agents to the concrete mix?

Do NOT add any retarding agents to a concrete mix that is going to be ground and sealed or polished. Retarding agents WILL affect the seal and may react badly with the polishing process. Simply apply a light sprinkle of water to the slab as required.

Can wet areas be polished?

Wet areas can be polished however we highly recommend that showers be either tiled or use traditional shower bases.

What is the difference between a sealed floor and a polished floor?

A sealed floor (also known as a Grind and Seal) is machine grinding to the desired exposure followed by a Surface or Topical Sealer just like a timber floor.
