Exact Answer: 3 Days is the Recommended Time
The answer to this question is a really simple one. It all depends on what type of skim coat you used, how thick it was applied, and the time since your last paint job.
After the skim coat has dried, you can paint your walls. But how long should you wait? Many people are wondering when they can start to paint their home after they’ve applied a skim coat. The answer is that it depends on what type of primer and topcoat you use.
If you’re using an oil-based primer or topcoat, then allow at least one week for the products to cure before applying another layer with latex paints or other water-based primers and finishes. Read more to find out the details!
How Long After Skim Coat Can I Paint?
|Type of Coat||Duration|
|True Skim coat||Will dry very quickly|
|Other coating||24 hours to 3 days|
The answer is a matter of personal preference and also depends on some variables. For example, do you want the paint to sit longer, or do you care if it starts to peel? If your house has been painted before, then waiting should be no problem, but if not, I suggest using a primer first.
Also, remember that new wallpaper needs at least two weeks to adhere properly, so for those painting right after skim coating, wait until all pasting is complete.
Once no more wet spots are left from the primer and dry surface, any oil-based paint will work well with your new wall since it does not suffer from sagging as latex-based paints can.
Paint a wall with a skim coat, and it can be painted after 3-4 days, depending on the temperature. The higher the temperature, the more time it will take. Full paint or primer is required to cover a skim coat in direct sunlight. When it becomes wet outside again after painting, wait at least 24 hours before applying a new coat of thin paint (as thin as you can get) over top of the newly applied paint.
This way, any lead solvent that might have seeped into the still-wet paint doesn’t finish its drying process while hanging out in exterior moisture where it could accelerate softening or wear away. In the end, cover the wall entirely and overlap the cut-in strips with a paint roller.
Why Should You Wait So Long to Paint After a Skim Coat?
Waiting for 3 days depends on the type of coating used. Also, make sure to know What is the purpose of a skim coat? The purpose is to insulate the already painted surface. If you were to paint over a wet skim coat, the wet paint would not adhere properly, and your new coating would crack right through it in no time at all.
And what causes cracking? Evaporation from heated surfaces, during winter months in cold climates especially! It means that you need to wait until it’s warmer outside before painting. Otherwise, any freeze-thaw cycles could lead to wrinkled finishes or even warped boards if moisture starts to penetrate beneath.
Hiding a coat of skim coat sometimes requires things like a half-hour, while painting may take only 10 minutes. If you paint on top of a skim coat that has been in place for less than 45 minutes, chances are good the finish will have problems such as poor gloss and surface texture.
Skim Coating is best done early morning when temperatures and humidity levels are low, which means it dries quickly. Unfortunately, it also takes so long because you need to sand the first coat with fine sandpaper lightly. Later wipe off the dust with a wet sponge before going to apply a second coat.
Also, remove all types of masking tape and re-install the electrical covers before primer coating.
Usually, two skin coat layers are applied, which means it needs this huge gap as it needs sanding between coats.
If you are ready to start painting, we recommend waiting 3 days after applying a skim coat as it may affect your final result.
If you follow the best practices, your wall and ceiling will look smooth without any significant flaws once you leave a significant gap between skim coating paintings. There won’t be air bubbles or, in the worst case, not any scratches.
