What kind of sand is best for dry joints

[Walter R.]

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.

Thank you

Agreed. The bags actually say, "Play Sand". Unfortunately, once you get them talking you can't shut 'em up!
