Question:
My porch concrete floor are somewhat flaw. I am mulling whether to scrub clean the porch concrete floor or install slate tiles over it? My question is - can I put slate tiles on the concrete?? And what shall I do about the side of the porch concrete? Again can I put tile or similar material on the side?

Answer:
You can put slate tiles almost anywhere, but you must take in to consideration the weather. If in the winter the temperature falls below say -15 then there is a slight possibility that the slate tiles could crack due to extreme temperature changes, on the whole though if you use a recommended flexible tile adhesive then this should compensate for any slight expansion or contraction due to changes in temperature. We would also recommend you use a flexible grout & ensure all the grout lines are well filled.
