We have trialed Hydrochloric acid, neat and diluted. Also a Hydrochloric based product with a fuming inhibitor, which also seemed to have the same application problems but without the noxious fumes. Do you etch wet or dry. How do gelling agents work?
Thanks Ron, we are after a fairly light etch to give a simulated natural stone finish, by the time we get an appropriate etch depth all over the face by reapplying we have large areas over etched. We need to avoid exposing the aggregate too much for the required effect. The patchiness appears...
We are experiencing difficulties acheiving a consistent acid etch on the surface of our pavers. Does anyone have experience with application methods for acidic solutions to pavers that will give an even overall texture? Both brush and spray applications have resulted in patchiness related to the...
