Painting & Decorating

Recurring shadow marks on all external walls, where the mortar lines surround the blocks

Ever since the detached brick and flint house was built in 1990 we have had to more often than normal redecorate (emulsion paint) all the exterior walls, the faces internal to the house. Over the years we have experimented with various solutions - stain block paint, vinyl paint etc without success. The shadow stains will "wash" off, but we are looking for a more permanent solution, we are fed up having to redecorate every 3 years. Although I am no expert the stains look as though they are being caused by an electrostatic effect, perhaps something special about the mortar they used between the thermalite/lytag (sic) blocks. Can anyone suggest a solution or visit to give advice, Regards Steve Gould
