    Hi, Someone told me years ago this helped, obviously products are different now water based.
    I've got an old building , maybe 1900 ,the ground floor gets cold.
    I'm wondering if I paint the exterior wall with some breathable sealant ( how is it possible that it's breathable ?)
    it would help a little to keep the walls a bit warmer rather than being soaked in Manchester rain ?
    Thanks

    If it’s warmth your after, then you need to insulate it. Either from inside or outside.

    Are the floors insulated?

    windows in good order?

    Water seal is only a water sealer, and will need reapplying in future years.

    Heat and insulation make it warmer.
