hammerite on MDF

Hello there
I am making an MDF plinth which will eventually need to be ... not
quite water'proof', but certainly water'resistant'. It's for a Moth
Record Cleaning Machine if anyone is interested!

I am wondering about using thinned down Hammerite for such a use. I
seem to remember reading years ago that Hammerite could be thinned
with ... something nasty ... and used for absorbent surfaces. Ideally
I'd like it to soak in a little to the MDF, and then maybe a second
coat, less thinned, to make a finished surface with less of the
characteristic hammerite mottling.

My colleague in this gizmo suggests Yacht Varnish as an alternative,
but tat sounds like a lot less fun ;-)

Any suggestions or comments?

Thanks very much
Jon N

You know there's a smooth version of Hammerite don't you ?
What's the 'something nasty' ?
How about diluted pva as a sealant first ?

Genklene (Trichlorethylene) as I recall, not particularly nasty
unless you happen to be an ozone molecule.

Its a very expensive primer - why not use pva as the primer?

For even more fun you could use polyester resin :-).

Isn't the smooth version of Hammerite called Smoothrite?

Oh I loved their adverts... "Any old iron..."

Xylene. It really is horrible stuff.

It was. Now it's called "Hammerite Smooth". Bet that cost them a few
quid in focus groups.

Ever try burning a Genklene soaked rag?

Don't!

Yes - although it isn't flammable if it is burnt, like all chemicals
of the group, you get a nice cocktail of gasses including Hydrogen
Cyanide and Phosgene. Burning is not a normal part of painting
however and in its normal form with fair ventilation it isn't
especially hazardous. In high concentrations it is an anaesthetic
(and has been used as such) and in vapour phase cleaning baths it can
be deadly if you manage to lean inside.

I once spent a pleasant evening in a large but not-terribly-well
ventilated workshop cleaning an engine with a gallon of genklene. It's
the only time I've ever been inebriated - the walk home was great fun
and I had all the symptoms of what I believe is called a "hangover"
the next morning. Who says teetotallers can't have fun?

That doesn't surprise me. A friend worked with Mr "Hammerite", in the early
days, it was mixed in the copper in the kitchen IIRC as a hobby! It's
obviously been improved since then!

I know someone who achieved the same effect by using meths as an

Genklene was only one version of Trichlorethylene, others versions were more
harmful to the skin.

For this reason and others, it isn't available any more. Modern de-greasers
are soap based and don't work anything like the old stuff did.

In my line of work (Aerospace), Arklone was very popular for de-greasing,
but was a very heavy solvent, both in weight and use. You could see the
vapours dropping from the point of application.

Can some one explain how this affected the ozone layer?

(it was banned about 5 years ago in the aerospace industry)

Arklone (CFC-113) (based on trichlorotrifluoroethane) and Genklene
(1,1,1-trichloroethane (methyl chloroform)) were banned for use in
the EU in open systems from Jan 96 and in most other process from the
end of 2001 because of the restrictions on such compounds brought
about after the Montreal Protocol, not because of health concerns.
There are certain temporary exemptions from the use ban for HCFC
solvents.  These are for precision cleaning of electrical and other
components in aerospace and aeronautics applications.  For these
exempted applications the use ban enters force on 31st December 2008.

The ozone depletion potential (ODP) of a substance is an indication
of its ability to harm the stratospheric ozone layer. CFC-113 has an
ODP of 0.8 and 1,1,1-trichloroethane an ODP of 0.1.

The process of ozone depletion is explained at

and <http://www.epa.gov/ozone/science/process.html>
