We have just lifted our carpet and are going to lay wood laminate. We have a built in marble fireplace which has been placed on top of the old hearth. Coming out from the front of the hearth is about 2 inches of the old concrete which sits slightly higher than the rest of the floor. How will we lay the laminate around the hearth? If we hammer and chisel the concrete to make it more level, do you reckon it will be good enough?
