I have an interior brick wall I was thinking of whitewashing, it's a pale brick so not sure if it would turn out ok. What sort of paint and technique should I use.
Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about white washing your brick walls.
It's great that you've received excellent advice from @TheRenoDad. I suggest having a look at this discussion - Living room transformation by @kbright. There you'll see that the fireplace has been white washed. You'll notice that because there are different coloured bricks in the brick layout the whitewash enhances the effect of subtle differences between bricks.
However, if they were a uniform colour that effect would not be noticeable. I propose comparing the photos of the white-washed wall and the white-painted wall and having a think about it. Generally, one way to do white-washing is to use a good primer-sealer and dilute it with water. You then apply this mixture with a brush and wipe off the excess with a clean rag.
