I've got a Michigan field stone basement that needs some touch up.
Previously made a weak first attempt but a small area took forever.
1). Dug all the lose stuff out and blew out.
2). Sprayed insides with Acryl 60 Additive Cement Bonding Agent. Let dry.
3). Used grout bag with a watery mixture and Acryl 60 to try to get it in deep.
4). Used grout bag to pour a normal slurry. It was painfully lumpy and sloppy and I was not a happy camper.
I need a better application tool for several rooms.
This one is less than $20 and seems like it would work better than the bag.
