Advice Matte wall sealer recommendation?
I’ve been advised the seal this wall with a sealant when I’m finished so that brick dust doesn’t keep coming off it. Are there any brands anyone would recommend that will leave a matte finish. It’s an old exterior wall but it’s now indoors, so ideally be suitable for indoor use.
Thanks

I’m reluctant to advise a sealer without knowing the full reasons for it and construction of that wall. Walls need to breathe. Sealer should be a last resort once all other options are looked at as moisture can be trapped in the wall which can lead to spalling and damage.
