DIY advice needed, please.

Some time ago I posted about an internal wall that had a shadow stain on it, I am now convinced it was condensation , but during the investigation I found there was no DPC on that wall, so I had a chemical injected system put in.

Following the installation of this I was advised to use a diluted version as a sealant on the "affected" part of the wall, before repainting.

Now I am getting the odd dark patch appearing which apparently can happen with PVA/silicone .

My question is, how do I get rid of it ?

I have always used 'damp seal' on anything thats like that.

Just finished a job that involved rendering outside following dpc injection,that was last summer and as siad just finished inside of all external walls.When i first surveyed the property the customer pointed out a stain in the middle of the wall,finally found out during works that it was an area of lime plaster that had been left during bad renovation works.
