• Mastercrete is easily mixed with cement, cures to a hard, tough, wear resistant surface & bonds (adheres) strongly to most of the building materials.
• Mastercrete can be overcoated by exterior emulsion coating or cement based paints. It can be applied to uniform thickness coating on horizontal and vertical surfaces.
• Mastercrete allows trapped water vapour to escape and prevents blistering and adhesion failure.
• Makes cement mortar or coating compact thus preventing salt penetration into concrete.
• It is unaffected by UV light and prevents discolouration of concrete and corrosion in steel due to its alkali nature.
  Mastercrete is resistant to water, dilute acids & alkali solutions. Coating is highly durable even in continuous contact with water.
• It is non-flammable, non-hazardous. Does not evolve toxic gases when exposed to fire. Non toxic to human being.
• Most properties improve on ageing. Resistant to fungus and microorganism growth.

Typical Applications

• Waterproofing of building terraces, toilet sunken portion basements, Waterproofing of water tanks & swimming pools.
• Bridge decks, traffic aprons, runway, parking garages industrial floors, factory floors, balcanies, mechanical rooms, side wall etc.
• Pools & Foundation, Reservoirs, Channels dams, watertowers, tunnels etc.
  Sewers, silos, foundation walls, swimming pools etc.
• Repairing of concrete & masonary walls - internal, external and terrace roofs by cement mortars.
• Renovation & protection of concrete against corrosion and salt petre.
• As an additive with cement paints which improves waterproofing property, coverage by 20-25% and life of cement paint.
• As a bonding agent for old concrete to new concrete.

Surface Preparation
Surface preparation is the most important step before application to get best results and to avoid failure.
1. The surface must be free from dust, coatings, loose particles, fungus, moss, oils,     greases and mould release agents.

2. Clean the surface by scrapping,sand blasting, grinding to remove dirt & loose     particles.
3. Treat the surface with 5 to 10% hydrochloric acid followed by complete
    neutralisation with water which will improve bonding of the coating.
4. Oils, greases and mould release agents can be cleaned with solvents.


A. Brush coating application
For waterproofing of terraces, toilet blocks, swiming pools, water tanks and
basements.
1. After surface preparation, pre-wet the surface with sufficient water.
2. Allow the surface to dry for minimum an hour. Mix 2Kgs. of OP cement with 1
    ltr. of Mastercrete homogenously till no lump or air bubble remains in the mix.
3. Apply coating by brush and allow it to dry for 2 hours before application of second     coat. Minimum 2 coats are required.


B. Cement paint admixtures
1. Mix 3-4 ltrs. of Mastercrete with 50Kgs. of cement paint homogenously to form an     uniform mix.
2. Apply the mixed and diluted cement paint by brush.
3. Allow to dry 2 hours before application of second coat.
4. It increases the covering capacity of cement paint by 20-25%.


C. Patching Mortar
Depressions, voids can be filled and levelled by using Mastercrete mortar. Use 10% of Mastercrete on cement weight.


Curing of Mastercrete Coating & Mortars
1. Mastercrete coating should be protected from movements or traffic for at least 48     hrs. and kept moist for the next 24 hrs. by sprinkling of water or covering with wet     gunny bags. Continue the moist curing for at least 72 hrs. before submersion or     ponding in water.
2. Curing must be continued for minimum 28 days before exposure to weather.     Ponding with water for 28 days itself is a water proofing test.


Storage & shelf life
