Dust from Sanding filler

[Andy13579]

Hi all
I have recently just filled a large amount of cracks in a room. And odd ones round the house using toupret fill flex and then toupret repair.. I need to sand down now before painting.

I was planning on just using a cheap triangle head small detail sander I had as there is not alot of filler petruding the surface..

However now wondering how much dust is going to be generated as I recently had to rip of old linning paper and that was shocking for dust..and I know dust is the new h&s hot topic.. other than a small Ffp3 mask and hoping the dust / filler drops on the bagged floor is it going to be a really messy job? Or anything I can do to mitigate it other than spending big money on tools I won't use again

It generates a lot of very fine dust that seems to hang in the air before settling on everything. Can you attach a vacuum to your sander? Might need an adapter but they are cheap. Second best option is a willing assistant to hold the vacuum cleaner hose near by. That gets most of the dust but still best to wear a mask

No fancy vacuum attachments.... Will the use just destroy a normal vacuum?

Flex and fill is great, but as you are aware it shrinks back, hence you needed to face fill it with (presumably) a powder based Toupret filler.

If your detail sander has holes in the paper, use that, jerry rigged to a vacuum cleaner (duct tape etc).

I have no idea which vacuum cleaner you have. If it is only sucking up a tiny amount of filler, you should be fine. If it is a cyclonic machine, eg Dyson, you may ruin it.

Some fillers are far more forgiving than others. The dust from powder based fillers often becomes statically charged and clings to everything. The dust from the light weight fillers such as Red Devil Onetime do not cling to surfaces. Equally, they don't tend to clog the pores in dust extractor (read: vacuum) bags.

I can 100% recommend one of these https://www.toolstation.com/mirka-d...MIkuuN4s6CiwMVh5ZQBh3UmhESEAQYASABEgJzaPD_BwE
I have a similar version and it removes almost all of the dust, a little trick is that I stick the vac outside 1 - to stop its exhaust blowing dust aroun and 2 so any dust left in the exhaust gets deposited outside.
I used to use a henry but that was before there hepaflow bags and I ruined it with brick dust so I now have a screwfix titan wet and dry vac which i use for DIY

The Mirka handy sanders are great, I have two different sized ones (along with about £3k of electric sanders).
