Can any one suggest a cure for a continued black mould stain on my shower room ceiling,i have tried all the oil paints and stain blocks and even installed a velux window but once i have painted it out after 2 weeks its back,even with loads of ventilation?
You will be at it forever if you keep treatiung the effect Cavalino, Its the cause you need to get to and in a shower/bathroom this usually means some form of physical extraction for the warm air.
