DEZOSIVE SA-90
SPECIAL POLYMER MODIFIED CONCRETE REPAIR MORTAR
DESCRIPTION
DEZOSIVE SA-90 is a ready-mix and non-shrink cement base dry powder provides smooth level surfaces with highly consistent repair mortar for special purpose concrete and masonry repairs. Due to high quality adhesives formulated in DEZOSIVE SA-90, it has an excellent adhesion to most common substrates.
It meets the requirements of the following standards: EN 1504-3
FIELD OF APPLICATION
- Repairing of cracks and porous surfaces
- Provides smooth level surfaces
- Underlayment for floors and walls before placement of new covering materials
- Filling voids and holes
- Can be used for surfaces that are in direct contact with water
- Suitable for hydraulic structures
- Applying fillet in water tanks, etc.
ADVANTAGES
- Excellent adhesion to most common substrates
- Non-shrinkage
- High mechanical strengths
- Early stiffening and hardening time
- Provides maximum protection against freeze and thaw cycles
- Improves impermeability of concrete
- No destructive effect on the steel
- Available in wide range of colors
- Easy to use
SURFACE PREPARATION
Surfaces should be clean sound and free from oil, grease, laitance and loose particles. Metal surfaces should also be clean and free of rust, oil, grease and contaminants.
The concrete should be presaturated for preferably 6 hours with water before application.
MIXING
DEZOSIVE SA-90 is simply mixed with water to yield a stiff easily workable compound with shrinkage compensating properties.
The quantity of water depends on the desired consistency but as a guide, it is recommended to add the entire contents of the bag into the pre-measured (4.5-5.5 liters approximately) water while mixing. Mix with a paddle mixer or trowel to ensure a homogenous lump free material is achieved. Do not try to remix the product after losing workability by the addition of more water.
APPLICATION
- Remove damaged concrete and prepare exposed steel reinforcement.
- Thoroughly clean repair area using high pressure water jet to remove all loose debris and contamination.
- Replace damaged concrete using DEZOSIVE SA-90, build up in layers if necessary.
Apply DEZOSIVE SA-90 with a trowel or spatula. Press hard by hand. Thicker repairs may be achieved by working in layers.
DOSAGE
The optimum dosage of DEZOSIVE SA-90 to meet specific requirement depending on porosity and rough substrate, the normal dosage range is from 1.5 to 1.8 kg/m2/mm thickness of layer.
CURING
Keep repaired areas damp, with spraying water at least 24 hours.
