3.05 CLEANING AND PROTECTION
A. Cleaning: |
| |
1. Good workmanship and job housekeeping
practices shall be used to minimize the need for cleaning
the masonry. Masonry wall should be dry brushed at end
of each days work and also after final pointing and should
be left clean and free from mortar droppings. Protect the
base of the wall from mud splashes and mortar droppings,
protect the wall by setting scaffolds so that mortar is
not deflected onto the wall and at the end of each day
set the scaffolding boards so that they do not deflect
rainfall onto newly laid masonry. The masonry laying technique
shall be such that mortar does not run down the face of
the wall, or smear the masonry face, after the joints are
tooled, cut off mortar tailings with the trowel and brush
excess mortar burrs and dust from the face of the masonry.
2. If after using the above outlined techniques, additional cleaning of masonry
is necessary, the technique, solutions and test area shall be approved by the
owner, architect and manufacturer in writing. The masonry shall be thoroughly
saturated prior to and at the time the cleaning solution is applied. Clean the
masonry only with an approved cleaning solution (Water, Vana Trol or Sure Klean
600) with a brush starting at the top of the masonry. The solutions and the method
of scraping shall be as outlined on the container by the manufacturer. Immediately
after cleaning a small area, the masonry shall be rinsed thoroughly with quantities
of water sufficient to rinse cleaning solution completely. High pressure water
and sandblasting shall not be used for cleaning except with the recommendation
of the manufacturer and the written approval of the architect and the owner.
3. Remove temporary coverings and protection of adjacent work areas. Repair or
replace damaged installed products. Remove construction debris from protected
site and legally dispose of debris. |
| B. Protection: Protect installed
product's finish surfaces from damage during construction. |
