have just given my newly plastered(dot n dabbed) kitchen/diner a mist coat of glidden magnolia water based contract matt bought from dulux centre..i have watered it down approx 30/40% as reccommended..is 1 coat sufficient to seal the new plaster ? or should i give it another coat before i sand the walls with 120grade sandpaper & do the filling in with polyfilla ? or another mist coat after sanding/filling etc before i apply the topcoats ? + i have a sanding block but is there any harm in using a palm sander on the walls which surely would be alot quicker..cheers again :)

Single mist coat is fine.

Why are you sanding a newly plastered wall?
just a light sand after the mist coat + a touch of filling in im afraid tbh..

You have misted the walls with contract emulsion although using contract thinning around 20% would have been ok, now if the application of the mist coat has highlighted any imperfections in the skim that would be lightly to show through the finish coats you can if you feel the need face fill lightly sand and and spot mist those areas, yet I doubt that you will need to do this.

In this case there is no need to sand the mist coat only carry on with your finish coats, apply two coats of your choosen colour and you will be fine.

Three mist coats is quick succession is best.
I know that many apply more than one mist coat, but one is sufficent, you have already thinned the contract more than enough and there really is no need to apply another one.

Yes there is a good reason. You end up with a uniform colour on which to paint.
Many topcoats (vinyl silk in particular) are very translucence and subsequent topcoats WON'T cover. Try it my way and learn something for a change. I tried it your way and it is inferior.
Well i'm rather suprised to here that you have difficulty in offering even coverage from a correct procedure, perhaps you should contact Akzo Nobel and PMG coatings to name but two and offer them this advice. I am sure they will find it very interesting.

You are talking rubbish. I've tried it your way and it's inferior. Get a life mate and LEARN to do the job right.
I have very good life my internet friend probably far better than yours.
