I posted a question on 7/4/09 asking about the best way to remove paint
from concrete cills (Wire brush V abrasive discs).

Thanks for all the advice. Job was booked for yesterday & today and its
been a good learning experience. Customer breeds rare cats, dead against
Nitromoors, so it had to be mechanical removal.

First off, visit to local Screwfix trade counter to buy wire brushes & dust
mask. Whilst there I spotted a Site angle grinder (made by Makita) on offer
@ £30. I don't use angle grinders a lot, so I've just bought Chinese
cheapies in the past. Since I was going to be using one for two days, I
treated myself.

What a difference! Sooo much easier to use & control I couldn't believe it.
Well worth paying a little extra for. Never realised how different a goodie
& a cheapie could be.

Anywho, I bought three wire brushes, a Titan bevel brush, a Bosch equivalent
and a Titan twist cup brush;

https://www.screwfix.com/prods/64592...el-100mm-Brush

https://www.screwfix.com/prods/72528...ed-Bevel-Brush

https://www.screwfix.com/prods/81337...t-Cup-65mm-M14

The twist cup brush was almost completely useless, hard to control & didn't
remove much at all. The bevel brushes are the tool for the job, really high
rate of removal without any damage to the concrete cill.

I bought the Titan & the Bosch to see if there was any benefit from the
Bosch branded one, which was over twice the price of the Titan. No
difference in performance at all. 48" x 8" cill took around 40 mins.

Brush wear rate is phenomenal though. Did two cills 48" x 8" and the Titan
brush was worn away completely. The Bosch brush lasted for four 24" x 8"
cills, so exactly the same rate of wear, but the Bosch cost £16.76 as
against £6.84 for the Titan. Won't be buying Bosch again :-)

The dust mask was a real revelation.
https://www.screwfix.com/prods/19176...P2-9322-Valved

The blurb said "3M cool flow valve reduces heat build-up" and it really did!
I've always had problems with dust masks causing my glasses to steam up.
Didn't happen at all with this. I'll definitely be using these again.

Interesting bit of info. The customer went to Brewers for advice about
paint. They asked about the preparation method and as soon as they knew
about the wire brush they recommended the use of an oil based primer, prior
to masonry paint. The reason being that the wire brush would leave tiny
metal particles in the surface of the concrete, which would rust & bleed
through the water based masonry paint. I'd never have thought of that,
Brewers obviously know their stuff.

Hope that helps anyone thinking of doing a similar job or buying an angle
grinder or dust mask.

Oh, BTW its an incredibly dirty job! SWMBO wouldn't let me in to the house
last night until I'd used the workshop airline to blow most of the dust off!

Totally agree about the 3M dust masks - I really don't mind wearing
them. All the Martindales and other things of the past were awful.

Hypothyroidism is a seriously debilitating condition with an insidious

Although common it frequently goes undiagnosed.

Did you see:

110V was still £30 though...

At that price I am tempted to get another - sometimes its handy having a
pair set up with different ends on.

Perhaps I have never used a really bad one - but most I have used
seemed similar in performance (although not longevity)

These are more gentle that you might expect. They are good for light
rust removal on metal. I tend to use:

for general cleaning up of stuff.

You should try:

https://www.screwfix.com/prods/13038...ree-Respirator

very comfortable, no steaming and complete protection against particles
and vapour (even smells - effective against nasty dog yodel after she
has been troughing at the cat's litter tray!)

Oh, BTW its an incredibly dirty job! SWMBO wouldn't let me in to the house

Some of those disposable all in one overalls with hood can be quite
handy for those jobs. (I cut a doorway through a cinderblock wall using
a 9" angle grinder once - at least with one of those on you don;t need
to wash you hair half a dozen times before you can even get the water to
wet it!)

Last one I bought was £8! Alledgedly 900w compared to 700w for the Site,
but no performance differeance, in fact the Site seems more powerful. Just
so much more comfortable to use.

I've used those in the past for light paint removal on a tile hung
elevation. Wouldn't have touched this stuff, layers up to 3mm thick in
place.

I didn't actually check the invoice there, I checked the 'all my purchases'

have just checked the paper invoice and the *******s charged me £31.31!

I use that 'all my purchases' feature a lot to check what I've paid for

Immediate e-mail to SF I think!

They prolly charged you for the 110V version - that is still £31 on the
