...
I have an ancient steel tubular radiator that fits nicely into a purpose
built alcove in my hall. It is rather attractive in an industrial sort
of way and has therefore been retained whilst all the other have been
replaced with slim modern units.
Problem: it has gained many coats of pain over the years, many of which
have run and generally been applied badly.
Question: do I strip it with Nitromors (or equivalent) and then
repaint it with difficulty or are there places that will dip, strip and
repaint radiators?
TIA Richard
Hi Richard,
If you'd like it brought back to its original condition, which is lovely,
then have it professionally done. But if you want something to do at the
weekend, then get your overalls on and off we go.
Because it is a metal radiator it takes a lot of heat, so the best way to
remove the old paints is to burn it off. Now burning it will produce fumes,
so this is best done in a well ventilated open area, outside if you can, and
can be done with a flame torch, the preferred method, or dump the radiator
on a big fire until it has bubbled and blackened then scrub at it with a
wire brush. The choice is yours.
When you heat the paint it should begin to bubble and blister, and just when
it reaches the point of leaving the surface, then it's time to move in with
your scraper, keep and old damp cloth beside you to knock the paint off the
scraper, and start to remove the paint in slow strong strokes. The best
scraper to use is the small triangular type, you'll see them in DIY Stores,
as it lets you get in to all the nooks and crannies.
You may find a pattern under the paint which you never knew was there, as
many of these old cast radiators where used for display as well as function,
so don't think you've reached a piece of stubborn blob of paint that wont
come off with the scraper and damage the design.
When you're satisfied that you've done your best, take a wire brush to the
rest of it to give you a keyed surface to apply your new coating to. The
best type of coating is a hot applied one, but they are messy to use and
tricky to apply, so stick with a good product like Hammerite, which comes in
both a smooth and hammered finish and a variety of colours, and it should be
applied with a large soft brush.
The reason I say a large soft brush, is that people tend to pile it on with
a smaller brush and make it look just as nasty as it was before. A large
soft brush holds more paint and lets you push the coating out over the
surface of the metal a lot better, and stops it clumping together in the one
place.
Allow the coating to cure off and you should be left with a brand new
radiator ready for connection to your system. If you take your time with
it, it should produce a lovely piece of ornamental art for the property. I
just love those old things.
Good luck with it.
