Yes , two coats would be needed but yes
Are you definitely buying this dulux one ? There are other tough mates out there that will be as good and probably cheaper....unless the dulux you show is on offer near by ?
Obviously Dulux often do a good range of colours but Crown , Johnstones , Leyland all do similar paints to the one you might be buying
My feeling is that very few flat , subtle matt paints which also describe themselves as TOUGH, WASHABLE, WIPEABLE ....actually are
I find a paint in between a matt and a silk finish ......a soft sheen .....usually a 4 on the johnstones scale on the side of the tin ....usually means it's fairly good at being gently wiped in case of a spillage , sticky fingers etc
But the further you move to a dull matt it's not ......and the more silk or shiny it is it's too bright and mirror like
I personally don't think the paint industry has managed to produce a low sheen , dull matt that covers the wall well but can be wiped clean or washed
Sadly a matt ....whatever they say .....tends to be fragile to dirt , liquid, moisture and stains
That's my experience
