Hi

I'm told there is some sort of sealant I can paint on external walls
that will help repel water, and hopefully prevent damp getting into
the walls.

I can't find anything on the internet - can anyone help?

Thanks in advance

Simon

Simon,
You should be able to buy something like Thompsons Damp Seal liquid from
most DIY sheds.

Easy to apply with a creosote/fence brush - donot try using a standard paint
brush.

Cheers
