| 521171 | 2007-01-31 19:51:00 | Greetings all,The story so far... In a cunning and skillfull move I spent a number of hours late last night painting the walls and ceiling of a room (a sleepout, nothing flash) with what I had presumed was an undercoat. Upon finishing the task in the early hours of the morning I discovered while packing away the now empty paint tin that I had infact used a water based enamel.... Anyone think its safe to now put a coloured topcoat over this or will it all fall off? Recommended next step? |

My advice- never do anything late at night that might scare the s**t outa you in the harsh light of day :stare: |

| 521175 | 2007-01-31 21:19:00 | it's the other way around that's bad... acrylic can't be painted over oil-based enamel.Yes it can, although I wouldn't recommend painting over the top of a fresh oil-based gloss enamel surface until it had dried thoroughly, been lightly sanded, then washed down to remove dust and any solvent residues. I always use oil based undercoats before putting on acrylic top coats because they penetrate better and seal/harden the surface. Once any oil-based paint is thoroughly dry and properly prepared you can paint over it with anything you like. Cheers Billy 8-{) |

| 521176 | 2007-01-31 21:30:00 | I hope paints have changed. I once painted oil over acrylic on my house. It didnt take too long before the nice new paint began to craze. The acrylic was moving under the heat of the sun. I had to burn the lot off down to wood and start again. Now I'm very wary of the combination. |

Once any oil-based paint is thoroughly dry and properly prepared you can paint over it with anything you like. Oil based paints probably are better for the reasons you give but they are a pain in the butt to use. Recently I was painting a bedroom, previously our two teenagers used it so I was changing the old bright red and bright blue walls to a pale yellow. Had to use a pigment sealer I was told, and the shop only had it in oil base. It dripped, splattered, had fumes and took ages to apply, and of course the brushes were a pain to clean. Now I hear that pigment sealers come in acrylic. :groan: |
