I have a rusty rear fire escape which I have refused to paint for about 10
years... i.e. it was galvanised metal and my Mum, God bless her, insisted on
painting it wit the end result it needed to be painted on a regular basis...
Anyhow, I think it is in danger of rusting through so I am going to get a
drill and a rust attachment on it in the next few days and then I will have
to paint it. I am looking for tips for metal painter/primer/rust treatment
for it. I am considering Hammerite's straight to rust treatment which comes
in colours, comes in big tins and apparently you can thin it and use it with
a spray gun (I have never used a spray gun before)
So, any advice on which paint to get and from where? Are there online
stockists that I can use as my local DIY store seem to deal in very small
tins only? Also, any advice on using a spray gun and are these
cheap/expensive tools to buy?
Thanks,
John.

I've used black smooth hammerite on heavy garden/field gate hinges.
Works well has survived our weather or a good couple of years without
obvious signs of degredation. Same can't be said for the galvanised
screws which are rusting nicely. Try not to create tiny bubbles which
form pinholes later, you do really need two coats to overcome this and
note that the second needs to be applied fairly quickly after the
first or you have to wait weeks...

My thoughts about a spray gun outside are that 5% of the paint will
end up on the intended object, 95% all over the neighbourhood.

Spraying is a way of getting a good finish with suitable paint on a large
surface away from any draught. Ie, in a purpose made spray booth, or
somewhere where spray scatter doesn't matter. For anything else, pointless.

Found a place that sells it online for about £35 - B&Q were a touch under
£50. Any views on the hammered versus satin versus smooth finishes for an
outside metal fire escape?

Halfords? Dunno about prices.

Probably. IMHO, Smoothrite's a con.
Thanks Steve,
Within about 5 minutes of trying the drill option today I more or less
concluded that it was the wrong tool. I took a look at angle grinders today
and wondered whether they woudl be a better tool - not sure what type 'disc'
to use with one though? Can you suggest one?
Thanks,
John.

Or if the OP can't find hammerite in stuitable quantites and price he
could try and track down the stuff that vehical restorers rave about
for use on subframes/chassis etc. I think it (or one of them) may have
been mentioned in the last month in here.
Distributors all over the place, website etc, you can hardly miss it

Also get a flap wheel since these are a little less aggressive than the
wire brush. Note also that hammerite can be painted straight onto the
rust without much preparation other than brushing off the loose stuff.

Those impregnated plastic thingies are a bit safer than a wire brush, IMHO.

Not the word after "and".

I purchased the cup type yesterday but assumed it was for use on a drill. I
just took a look at the B&D website and buried deep in it is a pic of an
angle grinder using the cup disk. I assume it can be used, as I did, on a
drill anyhow?

The kind of brush where the wires are twisted into thick ropes (tufts? "tufted
brush", something like that) last longer, IMO. Come in both radial and cup,
ISTR.

One standard procedure for removing bits of metal wire and bits of metal spark
from the eyeball is to use a dentists drill, and just remove the middle of the
rust spot with that.
*That* convinced me to keep a dedicated set of goggles with the grinder, just so
I'd never be tempted to not use one.

They also sell No. 1, which is IMO better than hammerite
(smooth or hammer finish), and takes a coat of ordinary
gloss very well....

I have both - for stopping "porcupine gut", you need the leather apron
or welding jacket. Kevlar is too loosely woven and the bristles stick
right through it.
Good quality brushes and using the twisted knot sort make a big
difference.

They're both disastrous (search the ng), but the hammered is worse.
Brushing Hammerite, especially in hot weather, is just asking for
trouble.

Morrisons the supermarket (ex Safeway) stock it.
