Hi, is it possible to lay a second layer of resin onto a fully cured floor (3-5mm). There are small areas where the resin is a bit thin and wondered if it's possible re-coat these areas with small amount of resin to thicken it up a bit. Or is it a case of having to pour another whole area over the whole floor?....it's about 1.5 metres square? Thanks

You will likely need to begin the wonderfully enjoyable task of removing the uncured resin via a combination of scraping and acetone. If you have areas of resin that have cured, you will need to scrape off the uncured stuff, clean it up with acetone until it is no longer sticky, and then likely sand off the cured stuff and start again. If you have patches of uncured resin underneath cured resin, then this is probably going to be very difficult to remove and it may be easier to scrap the project and start again from scratch.

You might like to try applying a bit of heat, if you've got some 500w work lamps that you can use to get the surface up to 50 degrees or so then there is a very small chance that this will cure the resin, even if it's just to a stage where it is easier to remove. But in all honesty, this very rarely works, so be prepared to scrap it and start again. 

Thank you so much for your reply. I thought as much. How gutting
