Vana Trol® is designed to simplify rinsing and reduces potential for efflorescence. Advantages Clings to masonry surface, and softens excess mortar and job dirt. Supplied in concentrate for easy on-site dilution. Slow-drying so it rinses clean without streaking. Controls green vanadium and brown manganese staining on color-sensitive brick and tile. Removes efflorescence on new brick, concrete block, and stone construction. Safe for use on most unpolished natural stone or cast stone. Designed for use with colored mortar. Limitations Repeated applications may leave a detergent residue. To reduce potential for detergent residue: always prewet; rinse thoroughly; do not exceed two applications. May cause color loss when used on Thin Brick or Concrete Brick. Always test a small area for suitability and desired results before overall application. Not effective for removing atmospheric dirt and black carbon stains. Use the appropriate Sure Klean® restoration cleaner to remove atmospheric staining from older masonry.

Always test for adverse effects prior to overall application. If testing is not feasible or indicates adverse effects, such substrates must be protected.
