vacuum cleaner

[elvasozim]

hello, i heard there is a piece of equipment which sucks out dust from a crack before you can treat it. were can i get such a thing. im in Zimbabwe (Southern Africa), so i need a supplier from anywhere in the world who is reliable and who will be able to send it to me

[Mr Bill]

I do not think that such a piece of equipment exists.

[old school]

I agree with Mr. Bill

On long open to the surface cracks I use compressed air from my compressor, this pushes the moisture out and drys out the rubber seal. Now with a crack like that you could use a strong vacuum and it might work.

For a damage not open to the surface you would create a vacuum with the damage but remove very little of the dirt once the vacuum was at it's maximum point, normally about 29inHg.

If a vacuum did work on a damage any other way we would suck out all the resin once we went onto vacuum mode.
