I have exposed a 100+ yr old brick wall inside, tuckpointed, cleaned with cup brushes on a grinder, and Sureklean 600. I don't have a picture right now but it looks beautiful.
I want to finish the wall with polyurethane or something mildly shiny but definitely not too much. What is the best coating to use?
After using Sureklean, what is the purpose of neutralizing? The instruction on the jug say neutralize with water + baking soda for indoor but not outdoor application.
