The drying process of waterbased trim paints
Is it safe to speed up the drying process of waterbased trim paints in order to achieve more coats in a single day?
Joe Elwick From Joe Pro Decor Asks The Question
Noticed a few comments about the rapid drying time of water based paints helped along by heaters ect… Getting all 4 coats on in one day ect…… Surely by forcing the issue, and promoting the drying process this, way can be detrimental to the paint…
Especially if coating over so quickly numerous times in such a short time??
It can have a bad effect on fillers ect….. So what do you think about paint?
If you’re working a 24 hr day maybe…. but over an 8 hr day can’t be a good thing. I can’t see how the paint can cure enough to recoatRoger Bell
Waterbased paint needs time to cure, over the set time period stipulated on the tin. It pulls in and hardens, giving a better finish!David Fuller
The big thing for Water Based paints isn’t heat. It’s air flow. If the room is to hot and the air is to dry you’re gonna have problems with the drying also.Stephen Dyson
I’d say 2 coats are fine to recoat once touch dry, but if you start building more layers then the ones underneath will take a lot longer to fully cure. Bit like when you go to peel a built up kettle and some layers are still tacky.Phill Southam
Re-coating too soon extends the cure time.Harriet Stone
I always follow the instructions on the tin.Elizabeth Pollard
Air flow way more important than heat, I’d say a maximum of 3 in a day, if first coat is 9am, 2nd coat 12/1pm, 3rd coat last thing. That’s the most I would push it and it depends on which paint your using.Adam Featherstone
I asked the question about the drying time of the advance products at a Benjamin Moore product day. It states 16 hrs recoat time on the tin and it’s touch dry within an hour ( under certain climes). The answer I was given was that as soon as it’s touch dry it’s recoatable. Crack onMichael Wood
