Learn How to Lay Blocks. Start mixing mortar mix as instructed. The first course of blocks should be installed below floor level and inside the foundation trench. This first line of concrete blocks shall rest on top of a layer of mortar mix. Spread mortar along the sides of the block and remove the excess mortar with a trowel. Repeat until the first course has been installed. Check the course with a level. Then, even it out with a thicker layer of mortar, if it is not.
Tile Over Tile. If the ceramic tiles are well bonded to the wall, it is possible to install new tiles right on top of the old ones. This technique works well in backsplash areas, because the new thickness of the wall won't be too noticeable. Use a cement-based thinset mortar to bond the new tiles onto the old ones. Beat the tiles in with a rubber mallet to keep them level and let the mortar set up for about 48 hours before grouting. Hide the edges of the installation with rail moldings or decorative tile moldings to hide the edges of both sets of tile.
