hi Sez, yes you wash it down without rubbing too hard, especially if there are cracks, so when the asbestos is wet it can't be of any danger, although that's still something to be careful of, because if it's wet it falls to the ground and doesn't float in the air, but still wear protective clothing as well as a cheap mask.
After you've finished washing as much as you want, the rags need to be thrown away, but they should be bagged and sealed, maybe a couple of times.
Do you know what type of gloss enamel you want to paint over, well if you don't know, then get a rag and dip it in methylated spirits, once you rub this on the surface and paint easily appears on the rag, then it's acrylic paint, that means brushes can be washed out with water, if nothing happens then it's turps based paint, so I need to know what type of paint it is.
If it is turps based then go to your paint shop and there is a paint where you can paint over this enamel to prepare for your acrylic, that would be safer than trying to rub it down.
Don't use a genie high-powered cleaner, but the answer is yes you can, talk to your paint shop and ask about this prepare paint to use. Geoff.
