Painting on Tarmac
ken555 - 24/2/21 at 04:54 PM

Not the Nordschleifer but more an allocated parking space, as the current one is almost invisible.

Has anyone applied thermoplastic numbers at "home" it needs around 200c to melt, would it be possible to get those temps with a plumbers style torch?

Alternative is the planners type paint and a couple of stencils but not sure how long it would last before needing redone.

I would think that a butane torch will get it more than needed especially locally, a hot air gun maybe better, certainly I have used a hot air gun to stick bitumen roofing down something normally done with a massive gas torch.

Can't comment on sticking the numbers down to tarmac.

Is this on private land?

If not then is it not someone else's job to do it?

Failing that can you fix a number to an adjacent wall or fence?

this type of paint is designed to 'disappear' reasonably quickly, will probably last 1-3 months depending on 'traffic'

That's impressive. I'd have thought a hot air gun would have struggled with a max of 3kW - my blow torch is the sort of thing they use for roofing and is rated at 68kW. Upping the pressure on the variable regulator will take it up to 110kW. As you can imagine, it eats gas!

So far only tested burning weeds off the path - at which it is *VERY* good - although I have actually bought it for silver soldering a boiler for a 5" gauge steam loco, but can't do anything 'til the end of lockdown, as I need to access materials and tools and work at my parents'.

I have a friend that works for a roofing company, so the idea of the torches used for that is a possibility.

If not I will investigate the line paint on Ebay.

Yes private ground, each tenant is responsible for their parking space. I could go with a house type number fixed to the kerb, but a post would be out of place. No traffic as such over the number, as its in the middle of the width.

I would rather work with my massive propane torch too but the hot air gun is much easier to drag onto the garage roof for a small patch repair.

I bought a very large burner for my propane torch for exactly the same purpose. By the time I'd silver-soldered the boiler I'd frozen the gas cylinder to the floor - in the middle of summer! This particular burner sounded like Concorde on reheat when I was using it.

I also had to wear a heavy coat, gloves and a metal shield with a hole in it for the silver-solder rod, as the heat coming back off the 40-pound copper boiler was horrendous...

Running them in pairs (or more) helps - we used to do that with a water heater at my parents' holiday home in France. It would work fine off a single propane bottle, but even during the warm summer months, if using butane, you had to use two in parallel or it'd cool too much and stop releasing gas.

Yes, I am expecting it to be incredibly warm work - when burning weeds off, just the heat coming back at me was impressive.
