Painting an External wall

lojeno

looking for advice on painting an external wall, it's a new extension, so at the moment its just the bare grey concrete wall, question is this: should i be sealing this wall with a primer of some sort first (it is an exposed wall) or just slap up the external emulsion?

Unless the fresh external plaster/concrete is very chalky,then theres no need for stabilizer solution.

A diluted coat of external paint (Dulux Weathershild watered down by 20%) will be fine as a 1st/base coat.

Once that has dried in,2 good coats of normal/undiluted external paint.


Use a 9 inch "long pile" masonary roller and also a wallpaper pasting brush to apply the paint.


Job done.:)

thanks paddy147, and for the pics

interesting that you mention 'chalky' there are some white lines/clusters that i thought looked chalky, and until you mentioned it i wasn't sure what it was. hard to say if its very chalky or not, i'd say its spotty at best. what would you recommend as a stabilizer solution?

thanks again

Run the flat of your hand accross the external plaster.

If your hand is very a very white chalky colour and small little bits of it come away from the wall,then its classed as chalky.

Any stabalizer sollution will do the job.Roller/brush it on,and leave for a day till you paint.

Builders providers is your best best for a bottle/tub of it.

defo getting little bits coming away from the wall, (like bobbles on a old jumper size of bits), but not so chalky as it turns out, but may put the stabilizer on it anyway, now just need a few dry days

thanks again!
