We had a hard time opening the pores in the concrete on our acid stain project, we used a chemical etcher and hand sanded as our hardware store had no floor buffer to rent. These efforts failed, and the acid still pooled in places. We think the acid helped open the pores and plan to restain before sealing. However, the puddles that dried into solid layers of residue did not come away with neutralizing and scrubbing with a soft brush - they seem to be very stubborn and in place. We don't like the matte look they have, and are worried they will interfere with the water based sealant - is there a prescribed method to deal with these prior to sealing? Sanding? Aggressive brushes?
