Thanks for the reply Martin.
Its a food manufacturing place, so its airborne particles of all sorts of foodstuffs.
When you say a hand sprayer, do you have a link to what you suggest?
The company have told me what they paid previously, and the timescales, and it doesn't seem too unreasonable at all.
Also may need to cover the odd machine etc, any idea where I can get a wide roll of plastic sheeting suitable for this?
There are also some horizontal beams that have built up dust, which we have to be careful not to spill into machines, so need to vaccuum it. Any recommendations on a vac for this kind of job?
Apologies for all the questions, just want to do it right if I take it on.
