CLEANING / HANDLING PROCEDURES FOR SMOOTH or SPLIT FACE FACE BLOCK
STORAGE / HANDLING:
Install units in accordance with best concrete masonry practices. Do not install damaged units and handle units in such a manner to prevent damaging faces, edges and corners. Carefully saw cut units for fixtures and bonding and remove any dust or paste that may get lodged in pores of face. E. Dillon & Company does not recommend the use of raked joints. All portland cement and masonry cement should meet applicable ASTM specifications. E. Dillon & Company recommends the use of Krete Gard Mortar Mix in the mortar. A colored mortar to match base color of units is highly recommended.
Product: "Sure Klean ® Custom Masonry Cleaner," general purpose cleaner for removal of light mortar smears, job dirt and normal job stains from new masonry surfaces. CAUTION: Do not apply Muriatic Acid to concrete masonry units
WARNING: These cleaning procedures must be followed. If cleaning other products (i.e. brick, precast, etc.) ensure that their cleaning agents do not come in contact or run down onto our products or damage could occur to the finish.
Good construction practices are the first step in obtaining a clean masonry wall. Excessive mortar smears are most often the result of poor workmanship. An experienced mason will construct walls with minimum mortar smears and droppings that will result in a wall requiring minimum cleaning effort. Extra care must be taken in keeping these units as clean as possible as you lay them. In addition to developing good masonry skills that will keep the walls as clean as possible from mortar smears, the mason must take the following steps to minimize cleaning requirements:
A test area (minimum 4 ft. x 4 ft.) representing surface conditions, must be cleaned before overall application to ensure suitability and the desired results. Test a small area to determine acceptability before cleaning entire job. Conduct test area of each type of masonry and allow to dry 3 to 7 days before inspection and approval by the project architect and/or building owner. Clean test area first according to the following application procedures detailed below. Clean surfaces within the time recommended. The longer mortar smears remain on the surface, the more difficult it is to remove.
NOTE: It should be noted that cleaning masonry walls typically gives the units a darker appearance than before cleaning. It is extremely important that a systematic approach in applying and removing the cleaner be practiced. The amount of solution applied, method and timing in removing the cleaner must be consistent throughout the process.
It is the responsibility of the mason to test thoroughly and follow the procedures outlined. E. Dillon & Company assumes no responsibility for the cleaning of the units.
