I have contacted the PIV company (Flatmaster 2000 | The Complete Ventilation Solution | Nuaire - https://www.nuaire.co.uk/residential/positive-input-ventilation-piv/flatmaster-2000) and they are very confident that condensation is not the problem and that the DPC (which I installed) is the most probable cause. The DPC installer is coming to see the flaky paint and salt problem in about two weeks time. He attributes the problem to salts coming through the newly re-plastered walls and intends to treat it with some sort of acid wash. I must admit that the more I hear about DPCs the more I am not 100% confident. I can just envisage it emerging elsewhere in the property.
I previously mentioned that the bathrooms will be retiled and hopefully that will avoid salt on the grout in these rooms. Can I just ask for your thoughts on the salt on grout in other rooms. Do you think that raking out the grout and re-grouting would solve the problem. Is there any specific type of grout I should use? Should I use anything else in the gaps before filling with the new grout?
As said earlier I am very grateful to those of you have taken the time to help me.
Muchas gracias
