Due to cost I will have to bite the bullet and paint the outside of my 200sq ft bunaglow myself but I want to do it properly. It has 2 new extensions and these are new plaster, left for about 18 months so should be ready now. What do I use to prime new plaster? Do I use polybond to seal it? Then give it 3 coats of dulux weather shield?

For the old bits I am going to thoroughly wash down and do 2 coats of dulux weather shield. Its the new bits I am worried about!

ps I have checked previous posts but none say what to do!
 
The good news is it won't take long to paint that 200 sq. ft. bungalow. :)

The unpainted walls will suck up the first coat so you could dilute the paint a little. Polybond is not necessary, although a lot of lazy painters use it.
