I’m repairing a 25+ years old (probably “ancient”) espresso machine,
that's still in fairly decent shape. Well, apart from the insulation on
The lagging material is most likely asbestos, and it is flaking. So far,
Removing the boiler from the machine is likely to do more harm than
good, so I think my best option is a “cover up” job.
That is, encapsulating the asbestos with some material, to stop the
flaking & leave none of the asbestos exposed. What I’m thinking of is
using a high temperature type of tape, or maybe a resin, or whatever
polymer, that can be easily applied “in situ”, using a simple brush, or
something. Using fiberglass, or carbon fiber to reinforce the polymer
might be a possibility.
Question is, what would be the material of choice for me?
The normal operating range of the boiler is around 90 C to 120 C (195 F
to 250 F). The material I’m looking for should easily be able to cope
with that, but, to keep a decent safety range, I would prefer to opt for
a material that can withstand much higher temps – maybe up to 200 C (400 F).
Needless to say, the stuff should be waterproof. Since this is an
espresso machine, the material will be sitting in a fairly humid
environment & might even have water spilled on it. Lastly, I’m sort of
on a budget, so what I need is something that’s relatively inexpensive &
I’m hoping to get your advice on the sort of material that I could use.
Of course, if you can recommend other possible options for dealing with
the asbestos issue that I’m overlooking, please do inform me.
