There is an old, but level, terrazzo tile floor in my bathroom. I was hoping to lay cork tiles over it to make it warmer but the adhesive in Wickes is apparently not suitable for glueing cork tiles to a non permeable surface. How should I do it please? Should I lay a?hardboard floor down first and if so what adhesive should I use to fix the hardboard to the floor! I dread the thought of having to remove the existing floor!!!!
thanks for your help
