Gas causes white spot on garage floor

[wmblanken]

Hi I used supercoat topped with their basic water based acrylic clear coat on my garage about 8 months ago. I spilled some gas (50:1) filling snow blower and when I went back to clean it up a few hours later there was a white residue that does not come up. So the gas has somehow reacted with the top coat. Any ideas on how to correct this? So far have just tried scrub brush but wanted to consult the experts before doing anything more serious.

It did what most water based acrylic topcoats would do, it turned white.

Sand it out, touch it up.

Thanks, this is helpful. Would you have any products that I could topcoat this with? Like a clear epoxy or polyurea? Would it adhere to the clear that is on there now if I cleaned and sanded it? Thanks!

You would have to sand through that weak clear, then can add a better sealer.

The brand you used is not tolerant of fuels and solvents and would need to be entirely recoated and grinded first.

A topcoat like our Armorclad 2-Part military grade topcoat is highly resistant to these kinds of spills.
