Features and applications

  • It is odorless, inert and impervious to acid and alkaline emissions, sea air, industrial fumes, etc.
  • Does not contain solvents.
  • Easy to apply.
  • Does not run or drip in high temperatures.
  • Completely stable and very durable.

  • It is used as waterproof protection in coatings of mineral wool fiber, fiberglass, etc.
  • Especially suitable, diluted in water, as a primer for floors and facings under a subsequent application of asphalt membrane.

Instructions for use

  • Substrate: Should be firm and free of dust, greasy residues or non-stick agents, and in general any substance that impairs adhesion.
  • If there are any holes or voids, the surface must be smoothed beforehand.
  • Application method: The product is applied cold after it has been homogenized.
  • It is applied just as it comes in the container or diluted with up to 10-15% of water.
  • It should be applied when the temperature is above 10ºC and below 35ºC.
  • When several coats are being applied, these should be done crosswise to each other, leaving the first coat to dry completely for about 24-48 hours before applying the next coat (depending on the level of humidity and the ambient temperature).
  • It should not be left directly exposed to the sun.
  • Cleaning tools: Work tools should be washed with plenty of water before the product dries. If it has dried, the cleaning can be done with an industrial solvent.
