What are the ideal conditions for painting ?

Clean swept floor, a put some water down to absorb dust and stop shit getting into your paint, (but dont flood the floor liike my mate did)

How far away should you spray the paint onto the object your painting ?

about 10" away from object

How many coats ?

Depends really no how much paint you got, but normally 2/3

How long between coats ?

depends on how warm it is in the bay, need it quite warm to help make the paint cure/go off, when tacky apply new 2nd coat
