Features & Benefits

• Stops water movement through concrete
• Protects reinforcing steel against corrosion
• Waterproofs minor cracking & seals shrinkage cracks up to 0.4 mm width.
• Its waterproofing capability increases with time. i.e. It remains permanently active.
• Does not get affected by surface wear or abrasion
• Can be applied to positive or negative side of concrete
• Non toxic, thus good for use in drinking water containments
• Treated concrete withstands hydrostatic pressure upto 150 mtr head.
• Easy in application, only mix water at site.
• Protects concrete against contaminated water & corrosion.
• Applicable on moist substrates.
• It allows concrete to breathe, but is not a vapour barrier
• Waterproofs by deep crystallisation, where slabs or concrete rafts / PCC are to be landscaped.

Method of Application

SURFACE PREPERATION to old and existing substrates :

• Remove dirt, laitance, loose particles, paints, etc., by means of mechanical grinding, sandblasting, and pressure water cleaning, or suitable mechanical means.
• Remove all protrusions,chisel out honeycombed / damaged areas, repair the cracks and work back to sound concrete.
• It is extremely important to ensure that the surface should be sound and thoroughly surface prepared, and vacuum cleaned to a finish of a sand paper, to allow Dr. Fixit Krystalline to penetrate effectively. This can be achieved by mechanical surface scarification, shot blasting, etc.
• Stop active water leakages using Dr. Fixit Instant Leak Plug, for severe infiltration.
• Thoroughly rinse the surface with water several times to reach a "saturated surface dry" (SSD) condition, where the surface should be damp, without any standing water.

MIXING OF DR.FIXIT KRYSTALLINE :

• Mix Dr. Fixit Krystalline powder to water in ratio 5 parts powder : 2 parts water for waterproofing purpose and 5 parts powder : 1 part water as a putty for repair purpose.
• Always mix powder to water & stir it well to obtain a lump free mixture. Mix only quantities to be used within 30 minutes. Mix Dr. Fixit Krystalline mechanically with clean water to a thick consistency. Separate containers of same volume should be used to measure powder & water.

DRY SHAKE APPLICATION

Before final trowelling, Dr. Fixit Krystalline can be seeded or broadcast, and then trowelled. Measure a 5 square meter area & broadcast a pre-determined amount of powder equally using a sieve or similar device, until the coverage is uniform & a consistent finish is achieved across the slab.

Spread 1 kg powder per sq. m. After the final set of concrete, only sprinkle water for initial curing. 48 hours later, ponding for regular curing can be done. If application is being done in direct sunlight, it is extremely important to cover the slab after final trowelling with a rigid sheet of polythene. Take care to see that the sheet is not in contact with the surface of the slab. This can be done by placing the sheet on bricks to ensure a gap in between the slab and the sheet, which will allow air circulation. Remove the sheet after 48 hours and water-pond to cure regularly.

Ensure thorough surface preparation by mechanical means, to remove all laitance, etc., to expose the pores in concrete and allow the penetration of the treatment.

All crevices and holes in concrete shall be filled with Dr. Fixit Krystalline powder mixed with water in a ratio of 5 parts powder : 1 part water.

Over a concrete substrate in a SSD condition, apply Dr. Fixit Krystalline mixed in a ratio 5 parts powder : 2 parts clean water, with a clean brush. Use an aggressive circular motion of the brush with Dr. Fixit Krystalline slurry. Apply a second coat after 3 to 6 hours.

Dr. Fixit Krystalline treated surface shall be left to cure for 2-3 days, as mentioned above and protect from direct sunlight for this initial period. For full cure, give 28 days along with concrete.

CURING

Completed application should be moist cured for a minimum of 2-3 days & protected from rain & light traffic for 12 hour. Start curing as soon as Dr. Fixit Krystalline has hardened sufficiently so that it may not be damaged by a fine water spray. Heavy traffic should be avoided until the surface has hardened, atleast for 5 days.

Finishes containing portland cement may be applied over Dr. Fixit Krystalline after 3 hours, but other finishes & paints should not be applied before 28 days along with concrete.

Back filling can be carried out after 36 hours of application of Dr. Fixit Krystalline. Backfill material shall be moist & not contain rocks or large aggregates.

Water tanks, etc., can be carefully filled with water after 3 to 7 days. Do not fill large tanks faster than 6.5 feet per hour ( 2 m / 24 hrs )

After complete curing of Dr. Fixit Krystalline, potable water tanks should be thoroughly rinsed with potable water prior to being placed in service.

Precautions & Limitations

• Application can be done under normal temperature conditions
• Heavy traffic should be avoided until the surface is hardened for atleast 5 days.
• Finishes containing portland cement may be applied over Dr. Fixit Krystalline after 3 to 4 hours
• Any paint or coating should be applied after 28 days only, over Dr. Fixit Krystalline application, after thorough wire brushing, washing & removing any Dr. Fixit Krystalline residual on surface.
• Dr. Fixit Krystalline has a high pH, when mixed with water. Use protective gloves and clothing & goggles for eye protection.
• Not recommended over moving joints and structures subjected to movements
• Do not apply on dry substrate..
