Is third coat of paint important

[kilo_4que]

I was wondering whether the 3 coat is important as several people have said two coats are good enough however on here people tend to go with a mist coat followed by two other coats.

Mist and two coats is the norm. Very occasionally you can get away with 2 coats, but not often.

Basically, if you're happy with the finish after 2nd coat no probs but you will find the third coat gives it a bit more "depth" and you have to put coat 2 on very well to get a decent finish.

is the sanding between the coats a must?

Im just so downbeat with the amount of painting i have to do. It took me nearly an hour to do a small 5x6 meter ceiling as regardless of which sleeve ive tried, they dont spread enough paint i.e. they spread paint enough to cover no more than around a 7 foot line a go and even that needs to be worked in. Mind you the end result looks good but takes forever.

Now considering the time it took me to do this part of the ceiling i need to do the whole building which consists of two large rooms of approx dimentions of 15x5 meter which includes ceilings and walls

Never heard of sanding between emulsion coats, undercoats yes, but unless you've got a load of grit in your paint doesn't need it!

Try more paint on your roller - see your other thread.

lol i was thinking this also as when you do attempt at rubbing down emulsion it peeles away plus so far mine looks so primed ready for a second coat i.e. looks to have a nice enough key for the second coat to cling to

With regards to more paint, I have tried this but still no luck. Dont get me wrong the result is top notch but just takes forever to deal with small areas
