I used it on these doors.
It’s quicker, safer, great next to glass and good for getting into corners/hard to reach areas.
I took the following from the Oricalcum website which I think explains it all:
The ultimate in rapid, safe paint removal.
You’ll never pick up a hot-air gun again. The original Swedish Speedheater system uses gentle infrared heat to remove paint, varnish and putty brilliantly at lower temperatures –
so you can say goodbye to scorched wood and cracked glass. It safely removes lead paint, too. After only a few seconds’ exposure, the Speedheater Cobra lets you scrape old paint off
easily, even in those pesky hard-to-reach areas.
Lightweight (at just over half a kilo), fast to set up and easy to angle, the Speedheater Cobra makes light work of removing paint from both wide-open expanses of paint and tricky
nooks & crannies. It’s perfect for removing old paint from furniture, door & window frames, marine details and stairways. We also supply replacement bulbs.
Safe, environmentally friendly paint removal
When stripping old paint which contains lead, lead particles are carried in the dust during sanding and scraping, and are released as fumes when using a hot-air gun. Even in relatively
modern properties, paintwork may contain lead: although the use of lead in paint dropped dramatically in the early 1960s, it continued quite legally with some paints until the early 1980s.
In 1992, EU regulations banned lead in all paints except those for use in historic buildings.
The good news is that the Speedheater Cobra safely removes lead-based paint because it works at temperatures lower than those which activate lead. Genuinely independent tests conducted by
an industrial research institute in Sweden found that, even under ‘worst case’ conditions, the Speedheater only released between 1 and 10% of the lead limits which are permissible in Sweden and the USA.
Gently removes paint from wood
The Speedheater Cobra’s infrared wavelength activates the water molecules in the old paint and softens it, causing it to bubble. The bubbling is due to the expansion of gases: some might
even ignite, producing tiny flames which quickly burn out. This is quite normal and, with proper use, the Speedheater won’t scorch wood.
Gentle on glass, too
Working close to a glass pane with a hot-air gun can be a tense affair, because cracking can happen no matter how careful you try to be. Used correctly, the Speedheater Cobra keeps your glass
intact because the heat is generated by radiation, not convection.
