Concrete dissolvers, descalers and brick-cleaning acids are all acidic, so they need an acid-resistant sprayer with VITON (FKM) seals, the same gear you would use for any strong acid. Reach for the wrong seal and the unit leaks before the job is done.
It is an acid job
Builder's acid, brick cleaner and concrete dissolver are hydrochloric or similar. Treat this as an acid-resistant application and confirm strong concentrations against the SDS. A stainless tank takes the abuse on heavy jobs. See the Chemical Compatibility Guide.

Common questions
What sprayer for concrete dissolver or descaler?
An acid-resistant sprayer with VITON seals, since these chemicals are acidic.
Can I use it for brick cleaning acid?
Yes, brick-cleaning acids are a classic acid-resistant application. Confirm strength against the SDS.
Poly or stainless for cement removal?
Stainless suits heavy, splashy work and lasts longer; poly is fine for lighter, occasional use.
