How to Remove Thick Mortar from Concrete Floor Without Sanding

Removing thick mortar from a concrete floor without sanding can be a daunting task, but it is possible with the right tools and techniques. Here are the essential steps to follow:

Gather the necessary tools:

Hammer drill with a chisel bit
Chisel
Cold chisel
Grinder with a diamond blade

Prepare the work area:

Clear the area around the mortar of any obstacles.
Wear safety glasses and gloves to protect yourself from flying debris.

Chip away the mortar:

Use the hammer drill with a chisel bit to chip away the thickest sections of mortar.
Hold the chisel at a 45-degree angle to the mortar.
Apply firm but controlled pressure as you chip away.

Use a cold chisel:

For stubborn mortar, use a cold chisel to break it up further.
Hold the cold chisel at a 90-degree angle to the mortar.
Strike the chisel with a hammer, using short, sharp blows.

Grind the mortar down:

Once the majority of the mortar has been chipped away, use a grinder with a diamond blade to smooth out the surface.
Hold the grinder at a flat angle to the concrete floor.
Use slow, even strokes to avoid damaging the concrete.

Remove the dust:

Use a vacuum cleaner to remove any dust or debris created during the removal process.
Wipe down the area with a damp cloth to remove any remaining residue.

Additional tips:

For thick mortar, it may be necessary to repeat the chipping and grinding process several times.
Use a hammer drill with a variable speed setting to control the force of the chipping.
Wear a dust mask to protect yourself from inhaling dust.

By following these essential steps, you can effectively remove thick mortar from a concrete floor without the need for sanding.
