Can I just paint straight over a moldy bathroom ceiling. Does it need to be prepped in some way? Thank!
This is a no no! It must be washed away/sugar soap/tiny bit if bleach or there are products available that you can paint straight over that will kill it off. It then needs to be blocked using a shellac, or oil based blocking paint, then it can be brought to decorating.
No you can paint straight over mold and need to be prepped frist
Hi, you should not paint directly over a mouldy bathroom ceiling. The mould has resulted due to poor ventilation and warmth when in use. Best thing to do is to sugar soap the ceiling to remove as much of the mould as possible. Use a strong solution of sugar soap and rinse well. Allow to dry completely with a window open. If the mould had been removed completely, I would recommend the use of a good quality mould resistant bathroom ceiling emulsion with at least 2 coats. If there was still evidence of mould then further cleaning and the use of a sealer prior to painting should be used.
Hope that helps answer your question.
All mold must be treated accordingly using a mold and mildew wash/cleaner and a damp cloth, wipe down all traces of black mold and then either given a coat of anti fungal paint to prevent mold from re appearing or oil based or stain block undercoat to cover stains and prevent them bleeding through top coat
Your best bet would be to wash it down with bleach, put anti mould paint then paint over that. Moving forward look at your ventilation in the bathroom.
Clean with bleach and paint with mould paint/ stainblock then use silk paint
No don't paint over straight away as it will come straight back through, apply a stain blocker first then paint
Mould will form in bathrooms where the moist air condenses onto a cooler surface and over a period of time goes black and you have mould grow on ceilings and walls and silicone joints.It can be prevented by having mechanical ventilation installed and where it has formed on a ceiling it should be cleaned as its toxic prior to decorating
You can not paint over mould
You can use white undercoat oil based first to cover mould and after 5 hours minimum apply emulsion if the undercoat is dry
Short answer is no the mould would just come back through, use some mould and anti fungal solution to remove the mould and allow it to dry naturally, then if you have poor ventilation in the bathroom I would recommend using permawhite paint on the ceiling, this will guarantee that no mould will come back through for 8 years, mould usually comes when relative humidity reaches 70%.
Yes you need to clean of mould first then stain block or cheaper option gloss over mould patches then paint.
Before painting remove the mold and paint the first mold paint available in the rough shop
Not painting over the mould u need a clean the mould and paint
It does need to prepare before you paint it thanks
