Emulsion over glazed walls - Method?

[jamiller]

I have a small room which appears to be a mottled paint effect covered with some type of clear glaze(not sure of exact spec Third eye !!). I want to go back to plain emulsioned walls, but, am wondering if I will come accross any issues(reaction or adhesion?). Any ideas how to have a trouble free project much appreciated. Thanks in advance

It could be oil based or water based glaze, or it might just be one of those all in one coloured glazes.

Better safe than sorry, I would give the wall a really good rub down, paying particular attention to wherever they would have bene cut in with a brush.

Then a coat of acrylic primer undercoat

Thanks for response Zampa !! What product would that be in the Dulux trade range - looked on their website but I seem to be missing the obvious. Regards John

if i were you i would just give the walls a damn good rubbing down then go straight over them with a good quality vinyl matt emulsion. acrylic primer a bit over the top.

It will be amongst the water based primers most probably...thin it out a little though say 15-20%

Failing that use a thinned coat of water based masonry paint, its full of acrylic

Ta mate. Masonry paint good suggestion - probably alot cheaper as well!!

Yep masonry paint is good at sticking to most surfaces (thinned) also makes very good wood primer..

Theres no need to call me god by the way...im good..im not that good..

hey
don't want sound like i am blowing my own trumpet but i am a pro decorator and have worked for the same company for over 10 years and now run the decorating side of the business , so i really don't think masonry paint or acrylic primer is neccessary, i am just trying to save the guy some time and money.

That was quite fashionable a good few years ago.

As your not too sure if its waterbased or oilbased, I would plump for the good old Oilbased undercoat method, or a primer sealer.
whack that on the walls, when dry, emulsion as normal.

Im not sure what would work out the cheapest really...a really good thorough rub down and straight emulsion..(no reason why that wouldnt work) or a quick rub down and something to stick to the glaze..

Having said that I did a job a few years ago papered striaght over old glazed walls with contract vinyl..I wanted to give it a good rub down but the contracts manager said 'just whack it on' ...so I did, fully expecting it to be off in the morning

Ten years down the line its still on...and we didnt even used 'V o V' adhesive.

Wheres growler when you need him...he normally disagree with everything eveyone says had has another way compltely..

The surface could be the Dulux duette stuff.

Anyhow, this is what I'd do and have done with 100% success on shiny surfaces.

I always have quite a lot of Johnstone's smooth masonry paint that i buy at they're sales now and again.

Wash and rub down , apply Johnstone's stormshield smooth masonry paint neat, not thinned with a roller.

If you thin it, you take the "goodness" out of it.

Thanks to all for your input. As it prompted a bit of a debate - I dont feel like I asked a stupid question ( for once! ). Spice - it was on the walls when I got here - it wasnt me - honest!!

Having said that lot:

I've never had a prob with with good quality emusion as philomahony suggests.
Just gives me the creeps these days, when I have to do it, so , Stormshield it is.
