Followed by repainting the ceiling in satin anti mould paint.

Is it any good...have you used it before ?

 

[CXRAndy]

Not used paint before. I had to sand away the original Matt white emulsion to create a key.

It went on well and looked good after two coats. I bought 1 litre can from Screwfix -Zinsser perma white multi surface anti mould

Why new builds put standard emulsion in the bathrooms is just cheap.

Does the Zinsser just block the mildew stain appearing through from the 'cold' side of the plasterboard?

Yes it is a blocking paint. You can get dedicated Zinsser stain block. If you have mildew, it prudent to sort the reason for mildew flourishing.

That's why I had install extra more powerful fans to my lads ensuite. Very poor ventilation. I cleaned down the signs of mildew, but realised the paint was bad, flaky. So I took it back to plaster in the bad areas and keyed the remaining ceiling for the Zinsser

He's told me the bathroom mirror no longer steams up when he finished showering

Making sure the ceiling is well insulated without cold spots in the corner & good ventilation is always a good start. Zinsser products are very good.

Years ago I fitted an extractor - the usual feeble one in the loft with a 4 inch pipe. Because of the route the pipe takes to the roof soffit, only a 4 inch will fit. I upgraded with a big fan unit and if anyone using the shower had a toupe (is that still a thing?) it would be taken hostage!

You know you've got good extraction when loo roll begins to unravel on its own. 😁

Might get me some of that,

Ours is problematic even with two good fans. It's a very small ensuite - shower, sink and toilet only. There is an extractor through the wall above the toilet - quite an expensive one that runs when it detects humidity or odours. It's pretty good and often running. I then installed a second extractor in the shower enclosure - in retrospect I should probably have put it on the left side above the shower head rather than the right. It's a proper extractor job with the fan in the loft and the hosing again going out through the wall.

I still get mould on the exterior wall by the shower and every time I repaint the paint starts to peel after about 6 months to a year. Just cannot get the condensation to go away. I did put the loft extractor in the middle of two equally sized runs of hose. I'm wondering whether it should be close to the extractor hole, or whether I just need a bigger fan, or whether I should move the extractor and put another ceiling light in the existing hole, or just install a second vent hole and tee two runs of hose together...

thats quite funny

A possible remedy would be to have a blower fan, that you can activate to draw outside air into the shower cubicle after a shower to air dry the walls quickly. Maybe a reversible fan instead of just an extraction. If the walls dry rapidly it should eliminate mildew

 

[Fastpedaller]

CXRAndy makes a good point - I was also thinking for the extractor to work, there has to be air getting in from elsewhere, as reducing mildew depends on good airflow.

 

[newts]

Increased airflow is required if you're still getting condensation. Either set the timer to run longer or fit a bigger fan.
A bathroom requires ~4 air changes to clear condensation. Most fans only run for 15 minutes after the light is turned off, small inline fans are 80m3/hr. This will give 2 x air changes (80m3/hr x 0.25hr =20m3) for a 10m3 small bathroom, not enough to clear the room.

 

[CXRAndy]

The xpelair I fitted has flow rate 187m3/hr. Combined with the constant running fan at full speed at 80m3/hr. They run 20 mins after shower stops. Then the constant running fan does 20m3/hr on low idle speed.

The ensuite is small, so I think should be adequate

I've spent the last week trying to level our lawn. I also cut the lower end of it back by 2 foot at the bottom. Luckily I saw a rotavator on marketplace for £30 and it's been a godsend. I now can't do much more until the retaining wall is up, else I'll lose all the soil over the step.

My dad wants to get rid of some I-section steel girders so we're using them for posts and slotting in some 40 year old 7x2s for the wall. They are bitchumen soaked and are still perfect, even after being used as kickboards for a cattle feed passage.

 

[Electric_Andy]

Here is the bottom slope end. The step up is now about 3 foot higher which I needed to do to make it level
