Abstract: An adjustable screed support for supporting one end of a screed during screeding of cement on a wall generally comprises a support bracket for attachment to the wall support structure including a stand-off portion extending outward, away from the wall support structure; and an elongate beam which is adjustably attached to the support bracket stand-off such that the distance of the top side of the beam from the wall support structure and the angle of the line of the beam the wall support structure are variable. The beam top side in side view is a straight line. The beam has holes side to side through its web portion and the support bracket stand-off portion has conguent holes. Cement from each side of the screed support flows through the holes and bonds to the cement on the other side.
