Question time lapse

Hi everyone.
How long should you wait for a first coat of paint to dry before applying a second coat? I used SW cashmere flat interior.
Thanks!

Good choice of paint. Generally you should wait a minimum of 4 hrs between coats. Overnight is better. The only danger of recoating too soon is if the first coat isn't good and dry the moisture in the second coat can start to disolve the first coat of paint = big mess. Tempature and humidity can alter drying times.

I agree, overnight is better
However, based on the temp, humidity, and an appraisal of how well it's drying (or not), I can wait as little as 4 hours
Meaning if I start at 7:30 AM an am finished by 11:30, I usually have no compunction about starting another coat after lunch at 12:30, if I start in the exact same spot and proceed in the exact same manner

* I will often bring my own heater and sweat it out in this case
* If you attempt the second coat when you shouldn't have, you'll know. It'll make a mess

I should have added that a lot depends on what is on the walls previously. A well painted/sealed wall will take longer to dry than a thirsty wall.

When in doubt, allow extra time. I recently tried to roll a second coat early. The paint was dry to the touch, but I didnít wait the required 4 hours. I stopped before I made too much of a mess, but it cost me extra work and valuable time.

If you are spaying, I supposed you may be able to rush a second coat, but I would ask the pros.

I have never been fond of spraying the finish coat on interiors. If you do spray the final coat on walls they should be backrolled - so the prior coat still needs to be dry.
