    Morning all.

    I have a Victorian brick single-skinned house that I'd like to keep as warm as dry as possible. I have been recommended Thompson's water seal, or similar.

    Is this a good idea or the start beginning of a nightmare? Or just a waste of time and money?

    Happy to provide more details if needed.

    Many thanks in advance.

    Nope.

    Can cause no end of problems.

    Why you wanting to seal the brickwork,usually damp is cause by other issues, broken pipes, poor pointing, leaking gutters,etc,etc.

    Bad idea. Bricks need to breath. Assuming you have single skin but 9" walls.

    Having said that, is using this stuff any different to painting the external walls with masonry paint?

    As does stone.

    There is no real damp at all. The thinking was to keep the walls dry and prevent water wicking away heat quite as much as it does now.

    9 inch walls.

    All these wall seal products do is trap water in the bricks in winter which then freezes and blows the faces off them.

    The previous owner of my house used it liberally and we've now got lots of damaged bricks.
