hammerite paint

[BeeJay99]

Give your base a wipe with some celly thinners on a rag, if it lifts you have the answer to how to remove it, was your lathe painted in cellulose originally ??.

I'll do that tomorrow. If it doesn't lift I'll try cellulose on the back to see what happens. I imagine it was originally cellulose, yes.

Did the the old hang-her-right not have glass/sand base in it?

I found it good for engine blocks too.

The American POR stuff is Overpriced Overated and Over Here It's got Vampire qualities too remember.

Epoxy does degrade in UV so depends how/where it's stored, and there's the 2k issues. E.g. my trailer was in bare epoxy and by 2 yrs was chalking up, but of course it does live in direct daylight.

The only downside to epoxies is the chalking but they are still giving adequate rust prevention even with a chalking surface. The 2k issue is not the same as isocyanates in poly 2k's. the use of an A2-P2/P3 mask is all that is required.

Reporting back a fortnight on

I'll do that tomorrow. If it doesn't lift I'll try cellulose on the back to see what happens. I imagine it was originally cellulose, yes.

I cleaned it thoroughly with cellulose thinners with no sign of any reaction with the Hammerite. Subsequently I sprayed a test area with an acrylic based aerosol. Neither caused the Hammerite to soften or react in any way as far as I can tell and the acrylic hardened normally.
It may be safe to conclude that once fully hardened Hammerite smooth becomes inert and can be overpainted with conventional finishes.
