You want to use mortar.


Brixment is a good company that makes mortar. Use the kind that you have to mix with sand. Don't get the kind that is already mortar and sand mixed. It is worthless.


Get the kind that you have to mix the sand in yourself. Brixment type m is what you need. Along with mason sand.





The ratio is about 1 shovel of mortar per 3 shovels of sand. Also directions come on the bag. It will tell how much water to use to get the right consistency.





You will need a masons trowel. It looks like a small hand held spade. You will also need a pointer. This is a tool that is a bout the width of a finger and is used to fill in the joints between the block. After you have mixed the mortar in a wheel barrow or mixer, Apply the mortar to trowel. Fill in the joints using the pointer. You may need a slick which is basically a real skinny narrow type of trowel used to place mortar in hard to reach areas. Once the mortar is in the joints, use the pointer(striker) to make the joint look real nice.
