Herein, can you spray 2k paint at home?
AFAIK it's not illegal to spray at home. 2k colour and clear is polyurethane and contains isocyanate. From what I've been told it's not illegal to spray at home, but businesses do need to use a booth, filtration etc.
One may also ask, how long does it take for 2k paint to harden? 6 - 8 hours
Consequently, is 2k Paint Dangerous?
2K paint (except for the non-isocyanate stuff) is extremely bad for your health, and should be used in nothing less than a well ventilated room, with the painter wearing a mask with an external air supply.
Do you need to lacquer 2k paint?
2K paint is direct high gloss paint, if applied correctly, you should not require any 2K clear lacquer. (6) 2K Paint and Clear Coats are direct high gloss materials and when applied correctly, you should have no need to cut and polish.
