Sandblasting Brickwalls

[mikeday1991]

Hi everyone!

Long time no visit to this forum!

I've just bought my first house which is a 1900's victorian terrace in Loughborough.
The property has an excellent basement, perfect for a workshop. The trouble is at the moment, the basement is extremely damp.

The brickwork is covered in a very thick paint. A damp and timber specialist has recommended blasting the paint off the walls!

Now I want to get some advice on which compressor/tank set up I'm going to want!

The compressor will be used for:

Blasting assorted car parts
Tyre inflation
Running air sanders, drills, impact drivers etc
NOT spray painting.

However it will be required to do a one off job of blasting a whole room.

Question is:
What size compressor will be required?
Can I get away with a smaller compressor + big upright tank? <(Desirable due to space implications)
Will car parts blasting equipment do the job for brick blasting?

Thanks in advanced!

Mike

I have a 1890's Victorian workshop and the bricks are very soft, just the "overspray" from blasting has dug quite deep into the brickwork. I'd use a soft media specially formulated for the job.

Really doing walls won't be much fun with a hobby type setup, it'll take days (it won't be any fun doing it inside either without a proper air-fed helmet (£200 plus)) and loads more air.

If you intend doing smallish car parts then the usual 14cfm jobbies will get you by with a blasting cabinet.

IMHO it would be better to get a firm in to do the walls, otherwise you'll be looking at a large compressor which you'll not really need, along with power supply considerations.

i have sandblasted a few complete houses to clean the brickwork up after re pointing u can buy the silica free sand specialy for the job . i used blown sand of the beach at the time the minimum size comp and blast jet size would be 90cfm and a pot with a min 6mm jet otherwise u would have to do it with a large power washer and a sand attachment very wet and messy
