Mortar not holding

I am building a block wall for the first time. I am continually having a problem with the mortar not holding. My panel is 16' long and three blocks tall. I've redone most of the runs a couple of times because the mortar did not hold. Please tell me what I'm doing wrong.

Welcome to the forums!

Are you using the 3:1 ratio of sand and mortar? or is it ready mix bags?

ibet you're using too much wtr in your bagg'd mix or not enuff cement & too much wtr in a field mix.,,, you should be able to hold' mix on your trowel upside down when 'buttering' blocks.

if you do have to repoint, clean the joint VERY well,,, then use either a hawk & pointing tool OR a mason's bag & same tool.

I'm using a pre-mix mortar, but it is highly possible I'm using too much water. I'll give it a shot. Thanks for the tips.

When laying up a wall of concrete blocks always make sure the blocks are dry as well. Wet blocks are harder to lay and the joints are weaker. Also, dry blocks make for a better looking job as the joints can be compressed and tooled more efficiently.
