What happens if you paint plaster too soon?

Why is my mist coat patchy?
With all mist coats on new plaster or plasterboard, it’s always going to be patchy due to slight variations in moisture in different areas of the wall and also paint application.
How do I know if my mist coat is working?
Your mist coat should be watered down enough that the water soaks into the plaster before it can evaporate so it gives you a bond. I would say it sounds like yours was a little too think – when you’ve done it the wall should look quite patchy and you should see the plaster through it.
What happens if you don’t use a mist coat?
It is likely to crack and to peel. If you don’t use a mist coat, you will find that any normal emulsion you apply afterwards sits on the surface. Painting your surface only with a standard emulsion and avoiding a mist coat will mean that you have to repaint it sooner.

Mist coat paint is simply watered-down emulsion paint, which acts as your primer. All you need to do is get some white emulsion paint and thin it out with water – it’s that easy! Three parts paint to one part water should work. If you don’t fancy watering down your paint you can also use Dulux Sealer for Plaster.

To make a mist coat, mix three parts emulsion with one part water. You should always check the paint tin for the manufacturer’s instructions as ratios can vary. You don’t have to use exactly the same paint you’ve chosen for the final topcoat but you should use a similar colour for an even finish.
Can you spray a mist coat?
So the mist coat is a very watered down coat of emulsion and as such can be used in most spray guns.
Do you cut in mist coat?
Newly plastered walls/ceilings always need to be suitably sealed before painting begins (otherwise the paint will sit on the surface & come off very easily). The mist coat dries rapidly & this bottom up method stops you getting fat splashes of paint onto the plaster. Cut in around the edges with a brush.
How soon can you paint after skimming?
To level a wall, you will need to use a backing plaster first, before you skim the surface. A freshly skimmed surface should take less time to totally dry. On average, it should take around three days for the skimmed surface to dry and be ready for painting.
Should I sand after mist coat?
If the walls are smooth to touch, you can apply your mist coat, if you have slight imperfections then I’d suggest to lightly sand down with a low grade sand paper. If there is any visible dust or any imperfections on the wall then sanding the walls before painting is recommended.
Do you have to wait for paint to dry before second coat?
Timing. Although your walls may feel dry to the touch soon after applying the first coat, wait until the paint has had enough time to cure fully before applying the second coat. Typically, your second coat of latex paint can be applied two to four hours after the first coat.
Why is my mist coat powdery?
The only problem you could have is if the contract paint is faulty. If you feel unsure, wipe the walls down with a dry cloth to remove any chalky residue before using your finish coats. If using a trade paint, diluting with around 5% water is always a good idea to ease application.
Can you paint two coats in one day?

How long does a mist coat of paint take to dry?
Apply the mist coat with a roller and allow to dry for at least 24 hours, but be careful to either remove or cover your floors and furniture because the mist coat paint will splash much more readily than thick emulsion. Once the mist coat is dry you can apply your top coats.
