Sealing External Brickwork

[DeludedAussie]

The weather is nice and people are getting outside of their houses painted!

I want to seal my brickwork and I have decided that one the following two products are suitable

Waterseal or Feb Silicon

I have read the technical data but I really do not know when to use the Feb Silicon. It is much more expensive then the waterseal

Can anyone confirm what the Feb Silicon is used for and how it is different to the water seal?

I'm no expert but this doesn't sound like a good idea to me. The walls need to breathe so that damp doesn't get trapped in.

Correct. Bad idea. The blurb on silcone sealants will tell you they are breathable but however breathable they are it won't be as breathable as when it's not there. Sealants merely trap moisture within the wall and make things worse.

Are you painting the wall or just trying to seal it?

not painting wall no - I want to seal it to ensure it stays water repellent

why would they sell this item if it was useless?
