Technical details

DUROSEALER is a consolidating surface treatment for application on hardened (after float finishing) or cured concrete to seal, protect against dust and evaporation, cure, harden. Its special formula enables the inorganic reagent to penetrate deeply into the pores of the concrete by 2 to 10 mm. Initially, the reaction balances hasty or uneven moisture loss of the casting, resulting in the creation of crystals that block and seal the support over time. This effect is generally inhibited a year after casting, when its overall action terminates.

Fields of application
Particularly suitable for industrial, quartz-finished concrete flooring. It penetrates the concrete, blocking the pores and transforming it into a solid and dense mass, preventing phenomena such as chalking, breakage and cracks.

Features
  • Neutral colour
  • Odourless
  • Non-toxic
  • Non-inflammable
  • Non-combustible
  • Can be painted with elastomers 7 days after application
  • Can be applied at temperatures between 5°C and 80°C.
  • Prevents frost and thaw damage
  • Limits penetration of damp The features of DUROSEALER develop over time:
  • Within 28 days after casting: guarantees perfect curing when applied to green concrete.
  • Within 60 days after casting: reacts with the concrete to protect it against dust and render it partly hydrophobe.


Technical specifications

  • Composition: blend of soluble silicates in water
  • Fully soluble in water
  • Drying time: touch dry after 1 - 2 hours
  • Can be walked on immediately after the completion of the application
  • Reaction time after application: 90 days
  • Specific weight: 1.12
  • PH: 11.5
  • Increase of resistance to abrasion: >30 %
  • Increase of resistance to impact: >12.5 %
  • Increase of resistance to compression: >38 % after 7 days; >35 % after 28 days.


Method of use
DUROSEALER is ready to use. On hardened surfaces (after float finishing), a single coat is applied by spraying (using low pressure spraying equipment), using a roller or a brush.

The surface can be polished if a smoother and semiglossy finish is required. Consumption depends on the porosity of the concrete and the room temperature. Recommended quantity: 150/300 gr/m2 Please consult our SERVICE DIVISION for information concerning the application of DUROSEALER on cured surfaces.

Storage
Store DUROSEALER in a cool and ventilated place. Storage time in the original unopened packaging: 12 months.

Packaging
DUROSEALER is supplied in 200/1,000 kg packs.

Maintenance
Clean the surface with plenty of water and a neutral detergent (do not use caustic soda), rub down well; eliminate oil and grease with an emulsifying agent for oils.

Warning
Protect the surface with care for the first 6 - 12 months as it may be subject to staining.
