Hi all,
Our builder is just finishing replacing some spalled bricks and repointed using lime mortar our red facing brick front wall in our circa 1890-1900 Putney, London mid-terrace house. He has recommended Thompsons WaterSeal to protect the porous red bricks from water ingress.
After being concerned about damp issues in general and reading this forum, I'm going to say no.
We had some damp in the front sitting room when we bought the house that was dealth with by installing additional air bricks. I don't want to cause trouble down the line by reducing the breathability of the wall.
Ronseal advises that Thompson's Water Seal is designed to protect against water penetration and damage while still allowing moisture vapor to evaporate. But I'm wary.
I figure after 120+ years and only a few spalled bricks, water penetration & frost isn't the problem. At some point the previous owner used cement mortar to patch up some damage. I'm thinking that this probably caused more damage from not being flexible enough. Hopefully the new lime mortar pointing will do the trick.
Am I right? If wrong, is this the right product?
cheers,
Fremantle
