Deliver preblended, dry mortar mix in moisture-resistant containers designed for use <br />with dispensing silos. Store preblended, dry mortar mix in delivery containers on <br />elevated platforms, under cover, and in a dry location or in covered weatherproof <br />dispensing silos. <br />E. Store masonry accessories, including metal items, to prevent corrosion and <br />accumulation of dirt and oil. <br />1.9 PROJECT CONDITIONS <br />A. Protection of Masonry: During construction, cover tops of walls, projections, and sills <br />with waterproof sheeting at end of each day's work. Cover partially completed <br />masonry when construction is not in progress. <br />1. Extend cover a minimum of 24 inches down both sides of walls and hold cover <br />securely in place. <br />B. Do not apply uniform floor or roof loads for at least 12 hours and concentrated loads <br />for at least 3 days after building masonry walls or columns. <br />C. Stain Prevention: Prevent grout, mortar, and soil from staining the face of masonry <br />to be left exposed or painted. Immediately remove grout, mortar, and soil that come <br />in contact with such masonry. <br />1. Protect base of walls from rain-splashed mud and from mortar splatter by <br />spreading coverings on ground and over wall surface. <br />2. Protect sills, ledges, and projections from mortar droppings. <br />3. Protect surfaces of window and door frames, as well as similar products with <br />painted and integral finishes, from mortar droppings. <br />4. Turn scaffold boards near the wall on edge at the end of each day to prevent <br />rain from splashing mortar and dirt onto completed masonry. <br />D. Cold-Weather Requirements: Do not use frozen materials or materials mixed or <br />coated with ice or frost. Do not build on frozen substrates. Remove and replace unit <br />masonry damaged by frost or by freezing conditions. Comply with cold-weather <br />construction requirements contained in ACI 530.1/ASCE 6/TMS 602. <br />1. Cold-Weather Cleaning: Use liquid cleaning methods only when air temperature <br />is 40 deg F and higher and will remain so until masonry has dried, but not less <br />than 7 days after completing cleaning. <br />E. Hot-Weather Requirements: Comply with hot-weather construction requirements <br />contained in ACI 530.1/ASCE 6/TMS 602.
