Specification
Mixing
- Application thickness: 5 to 50mm
- Thixotropic.
- Strong bonding.
- High compactness. Closed porosity delays the progression of carbonation.
- High initial and final mechanical strength.
- Excellent resistance to sea water and sulphated waters.
- Contact possible with drinking water.
- Repair of concrete surfaces: spalling, honeycombing, stair nosing, etc.
- Concrete restructuring: pillars, slabs, posts, dam aprons and spillways, etc.
- Reinforcement of weakened structures: balconies, overhangs, cornices.
- Treatment of chamfers and seams prior to waterproofing.
Application
- Apply a first batch of Du level mortar with a stainless steel trowel, pressing firmly to ensure bonding.
- Apply additional mortar to obtain the desired overall thickness.
- Trowel of float the repaired surface for a smooth finish.
- For large surfaces, the mortar may be applied by machine spray (wet or dry process).
Precautions
- Temperature range for use : 5°C to 35°C.
- Do not apply to a frozen or thawing substrate.
- Apply only to clean, sound resistant substrates, free of loose material.
- Cracks should be treated separately.
- Soak the substrate before application

- 12 months from date of manufacture if stored in unopened original packing in dry, frost-free conditions.
- Remove loose and damaged concrete and laitance using a point tools, chisel, or planiong tool in order to obtain a clean, rough surface.
- Clear out concrete around corroded rebars in order to create space for inserting the product behind and around them.
- The boundaries of the surface to be repaired must be clearly defined.
- The substrate must be free of all traces of grease and oil.
- Brush, scrape or sandblast corroded rebars in order to remove non-adherent rust.
- Dust off all surfaces to be repaired.
- Soak the substrate prior to application.
- If rebars are to be covered with less than 10mm of mortar, they should be passivated using either - a slurry mix of Du level and Tufex AD.
- Grey ready-to-wet powder.
- Active ingredients including hydraulic binders and synthetic fibres.
- Chloride and metal particle free.
- Du level protects steel rebars from corrosion.
- Portland cement concrete colour.
- Particle size :0 - 2 mm
- 1/2 Abrams slump cone measurements : l - 5 em
- pH : 12
Product Preparation
- The mortar is made by mixing Du level mortar with water.
- Machine or hand-mix for 3 minutes minimum until evenly distributed.
- Workable life after mixing: approximately 35 minutes at 20°C.
- No water must be added during application.
