Dry pack mortar should have a crumbly, dry consistency, similar to wet sand or crumbly clay. It should be damp enough to hold its shape when squeezed together in the palm of your hand, but dry enough that it doesn’t stick to your fingers.
When properly mixed, dry pack mortar should be stiff enough to be packed tightly into the area where it is being used, such as a shower pan or other surface, without sagging or slumping. It should also be compacted tightly to eliminate air pockets and ensure good adhesion to the surface.
It is important to note that the consistency of dry pack mortar may vary slightly depending on the specific materials being used and the application. In general, it is best to follow manufacturer’s instructions and recommended ratios to ensure a consistent and effective mix.
