Can someone please tell me an easy quick way to paint over walls previously coated with gloss paint?

Give the walls a wash down with wet and dry paper to key it. Then give it a couple of coats of the chosen emulsion. It might even take 3 coats depending on the starting and finishing colour. As always, don't take my word for it - wait for the approval of a "time served" tosher before proceeding.

1. Paint over the walls with a sticky primer like Zinsser's Bullseye 123 emulsion primer, and allow to dry. Zinsser's boasts that their primer will stick to hard-to-stick-to surfaces such as glazed ceramic wall tile, high gloss polyurethane floor finish, galvanized metal, etc.

Here's a UK site that sells the stuff:

2. Paint over the dry Zinsser's Bullseye 123 with your top coat paint.

I'm sure that'd work Nestor, but I'd use that as a last resort if the keying didn't work. That's expensive stuff you know.

Ok..mind your backs...expert coming through....

Using wet and dry to form a key is probably the best form of preperation for paint..however

Is a hell of a task over a big area, a couple of square metres may take me an hour (especially if im being paid by the day!!)..a whole room could be a very long job..not to forget the fact that each sheet is about a quid..

Id rub the walls down using 100 grade aluminuim oxide paper (thats 'alooominham' to you nestor) and then coat em with either acrylic primer undercoat..or dulux super grip primer (thinned by about 20%) ..Zinseer, as Gcol says is expensive stuff over here...about 14 quid a quart...

Or..you could always use an oil based undercoat..thinned by about 20%...allow to cure thoroughly for a couple or three days...then emulsion it..out will stick fine...but the only problem is painting oil based paint over a large area isnt to clever fume wise

Zampa me owd china, you need to move your arm a bit faster and not be so particular. Only joking. Surely you only need to just lightly break the surface sheen though? I'd probably just run round the room with the random orbital sander, dust off and then wallop some paint on.

and then wallop some paint on.

Hmmm...says it all really doesnt it...

tutututututututut...apply...the word is apply...

Your dead right though..you do only have to break the surface..etch it..but its a tough call doing a whole room like it..and quicker to paint...although you should still ket it up a bit

...one word of advice...

Dont dip the sander in a bucket of water if your going to use it with wet and dry.. .Zuuuzzzzzzzzzzzz <----(poor attempt at an electric shock sound)
