Internal Brick Dust

[Headshothelp]

I've moved into a house with a conservatory, three sides have 1/4 height brick walls and then there is the brick wall that was the external of the house.

The conservatory gets very dusty with brick dust. I have painted the three 1/4 walls white and it has made a difference to the dust. But it still gets way dustier than I'd like. I don't want to paint the remaining wall, is there anything I can use to seal the internal brick and prevent the dust?

Does it actually work though? That's why I'm asking for recommendations not just googling for random products

As in, its the dust I'm bothered by. Most sealanst advertise their waterproofing properties, or their stain resistance, which I don't care about

Water down PVA glue and paint it on. That’ll seal the dust in.

Something such as everbuild PVA from wickes or Screwfix will be fine. No need for fancy brick sealers.

between 1:5 / 1:10 will be fine. Glue being the 1.

My conservatory has 2 sides small wall, one side full ceiling to floor brick wall and then the other side is French doors into house (which is about 3 bricks to the left, right and top) of the French windows
Anyway I don't remember a dust problem, but in the end I painted the entire lot.
Looks stunning.
Not sure why I didn't do it sooner.

I agree, I think painted brick looks great, and I really like it on the three small walls I have done. However, I like the rustic-ness of keeping the once-external wall bare brick, it suits the aesthetic of the room.

@Acaseofthemondays thanks! That's tomorrow's job sorted :)
