3: Soda Blasting:

Soda blasting is also a good option for removing paint from concrete. You will need a soda blaster and also it is important to get the right kind of machinery because with sodium bicarbonate standard sandblaster will not work.

To get a close finish hold the nozzles of the blaster close to the ground and move it to the painted area. Soda blasting does not damage the concrete underneath and is more environmentally friendly than chemical strippers but it is an expensive option.

Try to remove the plants if you are blasting near plants because high PH soda affects plants’ life.
