Grout Removal With a Reciprocating Saw

Types of Grout

• Grout is nothing more than a concrete mixture pigment-dyed to match your tiles. Darker tiles tend to use darker grout, while lighter ones use a bleached or white grout. Sanded grout is more commonly used for tiles with larger gaps that need more strengthening than standard grout. Sanded grout is concrete, sand and the pigment dye that creates a stronger bond and can be more difficult to remove than non-sanded grout.

Reciprocating Saw

• A reciprocating saw looks like a big power knife. Unlike a circular saw seen by carpenters, it better resembles a jigsaw by providing a full range of motion and blade cuts that move horizontally back and forth. The saw is ideal for removing grout quickly and easily. You'll need to attach the correct grout removal tool to the saw.

Gap Size

• The gap between tiles determines the correct grout removal tool for your reciprocating saw. If the gap is measured improperly, you can easily cut and crack the tiles of the floor or wall. Use a standard ruler or millimeter ruler to measure the gap between tiles. Grout removal tools are available for gaps as small as 1/8 inch up to to 3/4 inch. Several brands and types of grout removal tools fit most reciprocating saws.

Removal

• Disconnect the standard saw blade from your reciprocating saw. After measuring the correct tile grout gap, attach the grout removal tool to the saw. The blade will be sold as part of a grout removal kit designed specifically for this type of saw. Turn on the saw and use a steady hand to place the saw along the grout line and let the tool remove the grout. Don't force the tool or you run the risk of slipping and damaging the tile. Work in small increments, brushing and cleaning up debris as you go, as sharp pieces of grout left on the floor can easily scratch tiles.
