U���^ <br />o��nmu wind drift onto autos and pedestrians by <br />protecting ordiverting such traffic. When working <br />over traffic, clean only when hnMic is at a minimum <br />and protect carefully. <br />Surface Preparation <br />New brick and tile surfaces clean most effectively if <br />the cleaning is done within 14 to 28 days after <br />masonry installation. Mortar and grout smears that <br />remain UV the surface for a longer time result in B <br />more difficult demVdownand may cause undesirable <br />results. Wherever poeaib|e, clean high strength <br />mortar/grout within seven [Ddays. <br />NOTE: Presence n{excessive moisture in the wall <br />contributes to efflorescence and other staining. <br />Always protect open wall cavities from rain during <br />construction. <br />Surface &Air Temperatures <br />Best [Jean/n0 results are obtained when air and <br />masonry surface temperatures are 40"F (4"C) or <br />above. To avoid honn to masonry _ do Oct clean <br />masonry when temperatures are ba|owfreezing or <br />will be overnight. If freezing conditions exist prior to <br />p|io$Uon, allow adequate time for masonry to <br />Equipment <br />Apply with spray (50 psi or <br />Uensmly-peuhed, soft-fiberad masonry washing <br />brush. Rinse with high-pressure 400 psi spray. <br />APPLICATION INFORMATION <br />Before applying, read "Protect" in Preparation <br />section and "Precautionary Measures" under <br />Safety Information. <br />Pretesting <br />ALWAYS TEST each type of surface and stain <br />before overall application to ensure suitability and <br />desired results. Atost area (minimum 4 ft. by 4 ft.) <br />must becleaned before overall application hnensure <br />suitability and the desired results. Conduct test <br />areas uneach type ofmasonry and allow todry 3to <br />7days before inspection and approval bvthe project <br />architect and/or building owner. Clean test onams <br />according to the following application procedures. <br />Test panel should remain available for comparison <br />—Mroughout the cleaning project. If test panel <br />--iU|ootos metallic disco|omabon, or if stains are <br />present before testing, nah»r to "Metallic <br />O|soo|oraUona^be|ow. <br />Dilutions <br />Always pour cold water into empty bucket first, then <br />carefully add 600 Detergent. Y0enmr use hot water. <br />Handle in rubber or polyethylene buckets only. <br />Acidic materials and fumes will attack metal. <br />The following dilutions are based on 1 part 600 <br />Detergent to recommended parts of water. Adjust <br />dilution rate based ontests. <br />Application Instructions —Exterior <br />Test thoroughly prior bJgeneral cleaning. <br />1. Thoroughly prevveta large area. <br />2. Using a dense|y-pgoked, soft-Obered masonry <br />washing brush, or low-pressure spray (50 psi <br />rnexinnun), apply the diluted solution freely. <br />3. Allow cleaning solution to remain on the wall for <br />3 t 5 minutes. Do not allow cleaner to dry into <br />the masonry because this may leave residue <br />and stain. <br />4. Reapply cleaning solution and scrape off heavy <br />buildup of excess mortar using a wooden <br />scraper or piece of bhck, taking can* not to <br />harm the masonry surface. <br />5. Rinse thoroughly with fresh water, removing all <br />cleaning compounds, free sand, loose material <br />and debris. Thorough rinsing is artnorne|y <br />important to ensure that all residues any <br />removed from the porous masonry. High- <br />pressure rinsing equipment providing at |meet <br />4DUpsi with 4to8gallons per minute, will prove <br />most effective. <br />0. Reapply asrequired following steps 1through 5. <br />Caution: K8u|Up|e applications may lighten the <br />mortar color. <br />Do not apply Ssma Kleanw 600 Detergent with <br />pressure spray above 50 psi. Such application <br />will drive the chemicals deep into the surface, <br />making it difficult to completely rinse. <br />NOTE: To avoid streaking, keep the wall <br />surfaces below areas being cleaned vve1 and <br />rinsed free of cleaning residues with clean <br />water. <br />Application Instructions --Interior <br />Test thoroughly and follow preparatory work <br />procedures above. <br />Fmkmv cleaning procedure outlines for exterior <br />surfaces. Rinse thoroughly with fresh water using m <br />sponge oraoft'fibered brush. If conditions do not <br />aUuvv sufficient water for complete hnsing, use m <br />neutralizing rinse following this procedure: <br />1. First, rinse with clear water. <br />Page 2cd4 <br />Item #10020 <br />Sx60oo'/2289e <br />aCopyright pRosOoO.Inc. 1wsa <br />
