Abstract: A mortar collecting device adapted to be located adjacent a wall surface of a masonry or brick wall under construction and collect excess mortar extruded from between rows of masonry during construction of the wall. Such mortar collecting devices each posses an upper surface means adapted to collect mortar but repel moisture in the form of water droplets which falls on such surface means. Repulsion of water is accomplished by providing an upper surface means having an inclined portion sufficiently inclined to the horizontal when such device is in mortar collecting position so as to cause moisture to slide off, but being insufficiently inclined so as to cause mortar to slide off. Alternatively the mortar collecting device may have a plurality of passageway means extending vertically therethrough of dimensions sufficient to allow moisture to pass therethrough, but of dimensions insufficient to allow mortar to pass therethrough.
