Red brick efflorescence

Pat201

Hello
I am starting to see a white powder form on red brick of a 2 year old new build. I can scrub it off easily using a brush but it comes back a week later. It seems to be happening around front of house where rain is hitting most I think. From a google search it seems like red brick efflorescence. Anyone know how to prevent and if this is a big issue ?

My parents built a red brick house n 1982 and it still suffers from this from time to time, but not to a great extent nowadays.

I remember there were large patches of it on the house and a friend of my dads told him to paint it with diesel. We didn't take that advise needless to say.

I have a bit of that going on in my house. Picked it up doing snag list with a builder friend of mine. The way he described it was the bricks were sweating, and that is was nothing to worry about.

By sweating I presume he meant divesting themselves of any moisture they contained.

Nothing to be overly concerned about and it does disappear over time.

Efflorescence is usually caused by poor handling/storage of the brick on site during construction. If the brick is allowed get wet/saturated on site, before it is used, this is usually the main cause.
