Can I prime one day and paint the next? That’s what I had planned to do, but when I bought Kilz odorless oil based primer to use under latex paint, the clerk told me I had to topcoat the primer within an hour after it was applied. The instructions say topcoat within an hour- but I can’t tell if that means the earliest you CAN paint over the primer or if you HAVE to paint over it within an hour. Thanks for any info.!
