Sealing interior exposed brickwork, lime mortar

[Mr Chibs]

Has anyone any recommendations for sealing exposed brickwork? Interior.

I’ve some old brickwork that I’d like to keep, read about pva, but didn’t think that would last well?

I don’t want the brickwork shiny.

Seal? Seal against what? Brickwork on a solid wall is never sealed, that is, unless you want to suffer damp problems.

Brickwork needs to breathe. Modern houses have a cavity so all you do is just keep the outer leaf pointing in good order. Slap PVA on the inner leaf as much as you want.

Any solid wall house with cement render or repointed with cement or sealed with Thompsons water seal / PVA etc... keep clear.

(The use of PVA, SBR etc.. is to change a high suction background into a low suction background for plaster and adhesives)

Cheers for that.

Seal for dust from the mortar etc, I would like to have an exposed brick wall in one of my rooms, thought it may be a good idea.

Since posting I've seen this, so guess I've answered my own question.
