Repair Mortar for Concrete




Dubond's DU LEVEL 30 is a thixotopic leveling product with characteristics of high pace hardening and drying, and best for irregular non planer substrates correcting up to 30 mm thicknesses on floors and walls. Its high qualities of thixotropizing polymers are resistant are resistant to an alkali environment and balance, before lyingofceramic, homogenoustiles, naturalstones, parquest and resilient materials.It is a high fluid, self-leveling product of high dispersing effect (HDE) technology that creates perfectly plane substrate. The substrate has extra rapid hardening and self leveling which lives with rheological fluidity and dynamism.

Areas of Application
DU Level 30 is suitable for internal uses for high resistance correcting (1mm to 30mm) of irregular and undulated substrates to be made ready for ceramics, homogeneous tiles, marbles parquet and resilient materials

Features & Benefits

  • Excellent self-leveling capacity.
  • Fast hardening and drying time.
  • High mechanical flexural and compressive strength
  • High bond strength on conventional cementitious substrates
  • No shrinkage
  • Excellent abrasion resistance


Low-absorption substrates
Smooth substrates with very low absorption or which are completely non-absorbent, such as ceramic tiles, marble floor tiles, epoxide paints, residual traces of oxidised adhesives and smoothed concrete coatings which are compact and properly anchored, must be prepared by means of mechanical abrasion. Any substances used for surface treatment, such as wax or parting compounds, must be removed mechanically or using specific chemical products.

High-absorption substrates
On screeds which are compact but very absorbent apply Hydroprime Primer in order to reduce and regulate the level of absorption. In the case of absorbent substrates with weak consistency, apply two coats of the primer . Respect the indicated waiting time before carrying out correction of the surface with a self-levelling product

Preparation
Prepare DU Level 30 in a clean container, first of all pouring in a quantity of water equal to approximately . of that which will be required. Gradually add DU Level 30to the water in the container mixing the paste with a low-rotation ( 400/min.) . Then add more water until a fluid, homogeneous, lump-free mortar is obtained. For best results and to mix larger quantities of self-levelling product, a stirring device with vertical blades and slow rotation is recommended. Specific polymers with high- dispersion properties ensure that DU Level 30 is immediately ready for use. The amount of water indicated on the packaging is an approximate value. DU Level 30 features a high degree of self-levelling capacity. Adding extra water does not improve the workability of the product, and may cause shrinkage in the plastic phase of drying and result in less effective final performance with a reduction in surface hardness, compressive strength and adhesion to the substrate

Deformable substrates
In the case of substrates which in any case are subject to flexure, apply Tuffex GT, the professional, single-component, water-base, adhesion promoter to a clean supporting surface, following the instructions for use. Attach an anti-alkali mesh with 4 x 5 mm mesh size and create DU Level 30 thicknesses ≤ 5 mm.

Large continuous surfaces
Continuous, extensive surfaces need to be fractionized with elastic joints so as to create areas of 50 M2.

Special substrates
Anhydrite screeds must be dry and sanded according to the manufacturer's instructions and impermeabilized with Hydroprime A eco concentrated, professional, water-base, surface insulation product, following the instructions for use. For subsequent laying of hardwood floors create a smooth finish of ≥ 3 mm thickness.

Health & saftey Precautions

  • During application wear protective clothing, gloves and eye goggles during application. Avoid product to contact eyes and skin.
  • Skin Contact: Wash immediately with plenty of clean water, use kerosene or mineral turpentine when the product has dried.
  • Eye contact: In the event of eye contact splash plenty of clean water immediately and seek medical advice.
