Mortar for waterproofing and protection of concrete structures. Monocomponent


White 25Kg - 350135
DANOCRET PROTECT 1C is a thixotropic, single-component, polymer modified mortar (PCC) for the surface protection and waterproofing of concrete, formulated on the basis of a mixture of hydraulic binders, selected aggregates and polymers that provide excellent adherence and waterproofing capacity.


  • Suitable for reducing rising damp in buried structures and lift shafts.
  • Waterproofing of balconies and terraces.
  • Waterproofing of bathrooms, kitchens and swimming pools before final coating.
  • Protection of concrete surfaces, for protection from seawater and salts.

Advantages & Benefits

  • High protection against saltpetre and seawater according to UNE EN 1504-2.
  • Good adhesion on non-enamelled substrates (1.1 N/mm², method EN 1542).
  • Elasticity ensures bridging of cracks up to 0.25 mm.
  • Avoids damp due to condensation.
  • Avoids the appearance of efflorescence.
  • Impervious to water.
  • Resistant to freeze/thaw cycles.
  • Accessible system under tile.
  • Good flexibility and adherence.


  • Mortar renderings
  • Concrete
  • Ceramic wall tiles and natural stone.

Instruction for Use

Preparation of the support: Once the waterproofing is done, the roof should be smooth, uniform and clean. Danolosa application: It is applied without any gripping material, deposited with care, preferably over a geotextile antipunching layer covering the waterproofing or directly on it, lying on the insulation face. Slabs will be placed without any expansion joint. On hipper ends and valleys the slab should be accordingly cut using a water-cooled low r.p.m. radial machine. A small space (3-5 mm) must exist, to allow dilatations coming from, for example, skylights, etc… It should be carried on pallets. Not considered as dangerous goods for transport.


  • Commissioning must be more than 7 days in contact with water.
  • Clean tools with water right after finishing. If there is solid dirt, we recommend scraping it off.
  • For application on wood fibres, ensure adhesion on 100% of the substrate.
  • Do not reuse the containers.
  • Protect the edges from rainwater penetration by preparing the substrates and using the most suitable product from the ARGOTEC® RERPARATION range to prepare them and prevent the accumulation of material.
  • It is recommended to apply a minimum of two coats of product of at least 1 mm thickness each.
  • Accessible after 24 - 48 hours of drying.
  • Once the mixture is ready, you have a maximum of 30 minutes to apply it.

Handling, storage and preservation

  • Keep the containers tightly sealed and protected from extreme temperatures (keep between 5ºC and 30ºC), protected from direct sunlight and heat sources. For a period not exceeding 12 months.
  • It is packaged in 25 kg multi-leaf paper bags with damp-proof sheets that allow it to be stored for 12 months in its original sealed packaging, safe from dampness.
