Removing melted plastic off concrete
 

I found what looks like a big pile of melted plastic/metal and some cloth rags. My friend said it's probably like some crackhead was cooking his shit on it or something? I'm not sure how it works and I can't really explain it properly... but basically right now it looks like a layer of hardened clay glued on top of my concrete tiled walkway.

There's another spot with a colourful rainbow of blue/green plastic that looks melted right into the concrete.

It's almost impossible to remove... right now I'm using a hammer and screwdriver to crack and pry off bits and pieces but it's a complete pain in the ass and chunks are breaking off and flying everywhere. I've worked on it for an hour and only got off about half of the bigger chunks, a lot of it is still fused to the ground.

I don't even know what to google or if anyone know if there any easier method?

Seriously... fucking bums... ugh

Step 1
Heat the plastic with a heat gun. Hold the heat gun approximately 10 to 12 inches away from the plastic to avoid overheating it. You do not have to liquefy the plastic -- you simply need to heat the plastic until it is pliable. If you do not have a heat gun, you can use a hair blow dryer. A blow dryer will take longer to heat the plastic.
Step 2
Scrape the plastic off the concrete with a putty knife.

Step 3
Reheat the area with the heat gun and remove any excess plastic with the putty knife.

Step 4
Sand the surface of the concrete with a concrete floor sander. If the area is small or you do not care about inconsistencies in the surface smoothness of the concrete area, you can use a small orbital sander to sand just the area that had the plastic on it. Start with a 60-grit paper and graduate to an 80-grit and then a 100-grit. The only plastic that will remain is the plastic that melted deep into the pores of the concrete.

Holy shit, danned.......... going from noisy pie plates to plastic removal......... I was so impressed, until I clicked on the link.



If it solves obsidion's problem, free sushi for you!

Theres a chance it could also be resin.

In any case, heating equals toxic fumes... sanding equals toxic dust.
Id get a large pry bar and hammer at it.

You get a thanks, I noticed you reply and assumed you were spouting off about the plastic being some sort of mind control or monitoring device put there by the lizard people but after reading your thoughtful response I was pleasantly surprised.

Goodjob Chuck keep it up.
