My friend’s flat is generally pretty good in that it doesn’t suffer from rising damp. But it has been rented out for the last few years and the walls of the bathroom have a severe case of mildew growth.
Things are so bad that the paint’s starting to peel off the walls and there’s more mildew behind the peeling paint. Basically we are looking at inadequate ventilation and a total lack of maintenance (otherwise known as cleaning!)
Mildewed Bathroom Facelift Step 1
First up we’re going to wash down all surfaces with a fungicide wash using a sponge. Wear adequate protection while you do this, gloves and a facemask are essential to stop you breathing in the fungus and protect you from the fungicide.

Next we remove all the old mildew stained paint from the effected walls. Large areas of paint came off when we washed down the walls so now we’re going to remove the rest of the paint using a metal scraper, sponge and diluted fungicide solution in a spray bottle (diluted about 50/50 with water). This is unpleasant tedious work but it has to be done if you want the finished job to look good and stay looking good. Some of the paint comes off easily, some of it takes a significant amount of work. We took 2 days off and on to get the 3 affected walls completely stripped back to bare plaster.

We now re-wash the stripped walls and woodwork with fungicide, clean all surfaces with water and leave everything to dry out fully (24 hours).
Our fungicide of choice !
Mildewed Bathroom Facelift Step 5
Unfortunately scraping off the old paint has revealed short sections of the galvanized steel corner strips which should be covered by plaster. The fact that they are galvanized means that they shouldn’t rust, but to be on the safe side we are going to prime the whole corner edge with universal primer. This is an oil based primer suitable for metal, wood or plaster and will stop the metal from rusting when the water based paints are applied. Obviously water based wood primer is suitable for this job. We apply 2 coats, just along the very edge of the wall from skirting to ceiling. Each coat takes 16 hours to fully dry.

While we are waiting for the universal primer to dry, we fill any blemishes in the walls and ceiling with Polyfilla. Ployfilla can be sanded flush after 2 hours and primed after 24 hours.
Mildewed Bathroom Facelift Step 7
We now paint the walls with one coat of “damp proof paint”. This is really a misnomer since the paint doesn’t really damp-proof the walls, what it does is stop the black stains left by the old treated mildew from showing through the new paint. Once the damp-proof paint has dried the mildew stains should be barely visible – if in doubt apply a second coat (in our case one was enough)
Mildewed Bathroom Facelift Step 8
The damp proof paint takes 24 hours to dry. During this time we clean the woodwork using 100 grit sandpaper and wooden sanding block and apply 2 coats of water based primer undercoat (4 hours between coats).
Mildewed Bathroom Facelift Step 9
So with the preparation done we can proceed with the fun part of redecorating. It is important that we use bathroom paint instead of normal emulsion paint. The bathroom paint resists condensation and mildew and, most importantly, can be scrubbed clean (coz with the best will in the world – Brighton bathrooms attract mildew). My preferred sequence is 2 coats on the ceiling followed by two coats on the walls and finally a gloss coat on the woodwork. Don’t try and skimp and do just one coat, after all the effort we’ve put in to get this far it’s worth the second coat to ensure a perfect, longer lasting finish.

There we go, a dingy mildewed bathroom has been transformed into a pleasant place to be !
