i totaly understand
what i mean is on here people say no need for primer just used watered down emulsion? (correct?)
Yes thats fine, its the same as priming
and no need for undercoat (just use emulsion)
Yes thats fine too, but the second coat is called undercoat whatever you use (emulsion in your case)
and thats all finished
No you should Top Coat
unless you want a tough scratch resistant & clean easy surface
then use a last coat of gloss, eggshell or satinwood
so what i mean is, is this the correct method thats in my head...without having to buy all the gimmicks
1.apply watered down emulsion to seal/prime (2 to 3 times on edges maybe)
Yes
2.apply undercoat (use emulsion again NOT WATERED DOWN THIS TIME)
Yes
3.all finished (unless needing scratch resistant and easy clean surface then do step 4
No you should really top coat
4.gloss, satinwood or eggshell
Yes all Finished
and use 120grit sandpaper between coats?
Yes if thats all you have it will be fine
p.s if painting anywood (not just mdf) should i use same method...maybe just no need to seal?
Yes 3 coats of paint, rub down between coats
Unless its going to be outside, then still same method but use oil based paints
i mean i know some woods arn't painted and waxed or oild (another thread for another time if i do something like that maybe
)
