Title: spraying acid
Post by: Richy L on October 09, 2013, 05:16:27 pm

Would a sprayer like this be any good for acid spraying?

It will work for a while - we used to use these to spray phosphoric and acetic at the soft drink factory but you really must wear a full suit

If I use it and give it a good rise after every use it will be ok will it?

I hardly ever do acid cleans these days

Thanks.

If I want to pipe it through some tubing to get to heights is there a certain type of hose I need or will a standard window cleaning hose work?

Pvc tube or any "plastic" should be ok. Go for nylon tube if you have push fits

What acid are you going to be using? these pumps don't like certain types of acid going through them.

Hydrochloric acid 36%(diluted 1:1)

I was told not to breath in the vapour or mist from hydro acid...?

It will handle it, but de-pressurerise when not using even for a couple of minutes, as the gases will build up under pressure and can make this type of sprayer blow.
Throughly flush out after use, and you should get some decent usage out of it.
Personally though I'd use Hydrochloric with a chemical brush and apply that way rather then spray.

Don't know but most probably, Tensid do them, around £10-£15 from what I remember.
They won't fit on poles though only hand-held

I've had good results using cheap B&Q sprayers with hydrochloric. Like Roger says, make sure you release the pressure whenever your not using it. I usually give it a good swill out a few times after use, then fill it up and pressurize is, then lock the trigger on and let it empty while im packing up, this way, you also rinse off all the trigger/hose/lance and seals with fresh water. I've had a good few months out of them using acid.

Not sure about wfp brushes, but most block brushes from the big sheds can handle hydrochloric. im assuming a stiff bristle cill brush would be ok with the acid. The ones with the plastic type bristles..
