I am laying bricks on an old concrete patio slab. Do I need to leave a
space between bricks in both directions? 1/8", 1/16", or, can I just abut
them?

What kind of sand is used for dry joints? I tried "concrete sand" but it
is too rough and has large, irregular particles.

get the sand used for kid's sand box?
