Looking at a a house with view to purchase. It has a high wall around
the carden. seems in good order - just a few spalled bricks on the top
- but I have seen some in same road a lor worse,
Built of normal facing bricks - top row has a tile under.
I was wondering if there is any substance I could paint on the top to
reduce moisture penetration and frost damage.


Just looked again - the side wall does not have the tiles under the top
course.
