sandblasting with baking soda

jaypea1

Any help will be helpful.
I am trying to get some graffiti off a wall. I have tried nitromors and pressure washer, while it have improved, there is still room for improvement.

Does anybody know whether sandblasting with baking soda is worth a try? Is there a type of baking soda to use with the pressure washer?

sandblasting works because sand is abrasive; i would guess that baking soda is not?

Usually chemical treatment is sufficient and washed down but would sand blasting not damage the wall's surface?

AFAIK, your local council retain private cos to remove grafitti vandalism and there is No charge for this service.

Would the baking soda not dissolve? I doubt that a solution of water and baking soda would remove the graffiti.
Cellulose thinners applied with a rag might be a better bet.

Soda blasting is a very effective way of removing paint and graffiti, its commonly used in vehicle restoration to remove rust as the bare metal doesn't rust after being blasted with Baking soda due to the chemical properties of baking soda.
It is also used in fire damaged properties to remove smoke damage as it has a deodorizing effect.
there are a few soda blasting companies here have a look at sodablast.ie

As CJhaughey says, it very effective all round!

I even tried it on a small scale with a compressor and sand blasting attachment, its quite the job!

Edit: And its very safe and fairly environmentally friendly!

Well I never.
That's great to know, I have know doubt that I'll end up using this technique sometime.

Is it used neat/dry or in a solution?

Well as a substitute for shot/sand blasting its used dry.
