We have just laid 30 sqm of slate tiles and they have white marks/stains on the edges. All the marks are on what was the bottoms when they were stacked on the pallet. I assumed they were just water marks from standing outside and would just wipe off. We have tried a stiff nylon brush and a...

We are renovating a house and need to move the head of the stairs back to allow for a new staircase with a left turn at the top. I originally thought the header ran just the width of the staircase but after lifting the floor I found it runs the whole way to the outside wall. In the picture. I...
