This may take some effort.
Removing brick from concrete floor.
I should warn you that you might find a slab underneath the bricks and that will require some different tactics.
Do not remove the putty knife until the pry bar is firmly in place under the brick.
One method involves drilling a series of holes in the relatively soft clay of the brick then chiseling the brick out in pieces.
And it s great for creating durable surfaces.
Yet when you need to remove it it can be a nightmare.
Wedge the pry bar in underneath the putty knife.
Lift the brick and discard.
One tip would be to start at one corner and break up a brick then chip away the subsequent bricks in the direction of the empty space.
Apply pressure to the pry bar until the brick pulls free from the floor.
Removing mortar from concrete slab floor can be tricky.
Mortar is a cement based paste that is used for binding building materials like bricks tiles and stones.
I show you the tools you will need and then take you through this br.
But if you pull up old tiles it may be something you will have to contend with.
That way rather than having to reduce the bricks to dust you should be able to pop them out whole.
Slip a pry bar under the putty knife and pull out the putty knife.
Do not be afraid to cause damage to the brick or the surrounding bricks.
