Mono Colour difference

evening lads

Done a k rend York just over 9 months ago. The front of property is all brick apart from the bay which is studding, we render boarded it and then hp 12 and finally top coat, was fine for first few months and started to go almost white. so re top coated again fine for a few months and now gone almost white again. any ideas ? has anyone tried painting a clear sealer over anything like this to see if will darken it up a bit.

Thanks

the dark colours seem to be the worst. there is a blue ,block of flats locally, that has now been painted as the colour ran out with white stripes.

Sounds like lime bloom? As Malc said, the dark colours are the worst. Is it on both the brick and board?

no mate all brick is fine just over the render board part. I was thinking maybe the heat of house through the studding is drying it out loads ?. definitely the darker colours are a pain in the ass

A new one on me this? Just the board?

Well I hope someone has the answer. Got me thinking this one.
