Instruction for Use

“Before applying the product on the substrate, make sure it is dry and clean of solid remains and irregularities.

Apply by roller or brush.

First repair cracks and apply DANOBAND® Butyl in the corners. On very porous substrates it is recommended to apply a primer coat of DANOPRIMER® W or REVESTIDAN® Indoor diluted 1:1 with water.

Once the first coat is dry, apply successive coats of undiluted product. A minimum of two additional coats is required. Wait until dry before applying the next coat.

Drying time between coats is approximately 3 hours and will vary depending on temperature and humidity. After applying the last coat, wait 24 hours to 4 days, depending on temperature and relative humidity, before applying the final coating.”


  • Clean tools with water right after finishing. If there is solid dirt, we recommend scraping it off.
  • Do not use on continuously flooded surfaces, swimming pools and tanks.
  • Protect from sunlight. It must always be under a liner.
