Hello, I'm new to this post and have a question about keeping the fire bricks wet after setting them. I have a kindly but nosey old neighbir who keeps telling me to keep the bricks moist after I have set them. I'm using fire brick and a premixed, high heat motar called BNZ Black Bond Refactory Mortar.
Thanks in advance.

I think dmun and Crival's directions are pretty good. I'll add a few tips:

Before starting, get all metal surfaces, including the exterior frame and the entire wheelbarrow wet. This will help prevent crud buildup.

Use two separate shovels. One "dry" exclusively for the cement, the other "wet" for the aggregate and mixed concrete.

Always turn off the mixer if you have to put a shovel or stick in it to scrap off any unmixed stuff. There is a huge amount of torque available and a jammed shovel can cause some serious injuries.

I would mix it longer that 3 min. I mix for 5 min minimum.
