There's no better way to refresh a room than by removing the existing tile and replacing it with a new design or colour. It can be difficult to remove tile from a window sill, especially if it's been there for many years, but, given the right amount of preparation and concentration, it can be done in a very economical fashion.
Wedge your putty knife in between each tile and pound the handle with your small hammer to remove the grout for each individual tile. Repeat this for every tile until the grout is loosened.
Attempt to pop the tiles off the window sill by driving the putty knife under each tile at a small angle, with the blade nearly parallel with the floor. It's OK to hit the end of your putty knife with the hammer to free each tile from the cement underneath.
Pulverise the cement underneath once you have removed all the tiles from the window sill. Wood might be exposed underneath the cement, so use a shop vacuum to remove the cement debris.
Drive the garden spade in between the wood and the cement board, lifting the cement board 6 inches above the wood board. Keep moving the spade left and right to pop the entire cement board from the wood board.
Continue to pry at the board, especially if there are nails in place to keep the two parts together. If necessary, use the pry bar to pop the cement board off completely.
Remove the cement board when it's completely freed and dispose of it properly.
Vacuum the remainder of the debris up with your shop vacuum.
