Screeding Sand for a Brick Patio: Using Rebar Guides for a Level Base

To screed a 2-inch sand bed evenly, lay ½-inch rebar pipes on the compacted base at the desired final sand height. Pull a straight 2×4 or screed board across the rebar to level the sand. Remove the rebar and fill the grooves with sand, smoothing with a trowel. This ensures uniform depth, which prevents paver rocking and settling.
