help for painting new plastered walls

[cleeto]

Hi..Can any one try and explain to me why after putting at least 5 coats on my newly plastered walls I still have a orange peel effect,
Yes the plaster was completly dry we sized the walls. we then put one coat of matt emulsion on but didnt like the colour ..so we bought wicks matt trade emulsion..and applied 3 coats with a roller..I asked the paint guy in b and q and he said we are putting too much paint on the roller..bought a new roller and tried to roller it in tray more..guess what same effect..Can anyone tell me what I am doing wrong at this rate ill end up putting wallpaper back on , which I dont really want to do Its cost me £900n to get them plastered.

Are you saying your sized the new plaster before mist coating it? What did you size it with?

New plaster can be sized rather than painted if you intend to hang paper but if you’re going for a paint finish, new plaster should be mist coated before you do anything else. Use ordinary matt white emulsion thinned 25-30%, 2/3 coats in quick succession, leave overnight & then apply you chosen finish. I always slightly thin topcoats as well as it goes on easier & gives a better finish; I usually use a large brush rather than roller, I don’t like the mottled effect finish they give.

I fear you may have created yourself a huge headache in what you’ve done.

I'm assuming you mean the emulsion finish, has an orange peel effect. This would have been caused by using the wrong type of roller to apply the paint. I think it sounds as if the roller was too course/heavy duty.You would have been better with a finer roller, or as Richard said, a brush.
For the future, no matter how many more coats of emulsion you put on, you'll never get rid of it. It might be better if this topic is transfered to the Painting and Decorating Forum,, they'll maybe have some useful advice on the problem. Good luck to you anyway.
