I want to install wood stair treads over a concrete and tile flight of stairs. The tile is porcelain tile.
I couldn't find any tutorial that addresses this specific scenario. Do I have to remove the top tile or have to drill holes to secure the treads (would rather not, but will if I have to)? Is construction adhesive sufficient? Tile is nice, flat and even.
May be obvious but I'm not in professional construction business. Just a DIY'er.
