DIVISION 04 MASONRY Page 3 of 3 SECTION 040307 HISTORICAL - MASONRY REPOINTING AND REPAIR PART III EXECUTION 3.1 Examination.1 Examine work on which Work of this section is supported on comes into contact and do not proceed unless surfaces and conditions are acceptable..2 Commencement of Work will denote acceptance of surfaces and conditions. 3.2 Removal and Preparation.1 Remove damaged/deteriorated clay brick masonry..2 Clean out all defective mortar joints to not less than twice the depth of the width of the joint..3 Provide temporary shoring to safely support the loads where removal of masonry affects the structural integrity of the wall..4 Establish lines and levels for brick coursing and protect from disturbances. 3.3 Reinstatement.1 Replace clay brick masonry in full beds of mortar. Surplus mortar shall be removed immediately from all brick and adjacent surfaces..2 Prehydrate pointing mortar by mixing ingredients dry, then mix again adding just enough water to produce damp workable mix that will retain its form when pressed into a ball. Allow to stand for not less than 1 hour but not more than 2 hours then remix with sufficient water to produce mortar of proper consistency for pointing. Tuckpoint with new mortar and tool joint to match existing..3 Mortar to be layered ½" maximum where deep joints occur. Allow to dry prior to installing subsequent layers. 3.4 Cleaning.1 At completion of brick/masonry replacement and tuckpointing remove all rubbish and surplus material and brush and clean all masonry with water and a stiff brush..2 Mortar staining/residue on brick surface is unacceptable.
