FEATURES AND BENEFITS
1) Portland cement-based two-part substrate waterproofing material in accordance with ANSI A118.10.
2) Waterproofs all common substrates in residential and commercial bathrooms, showers, and kitchens prior to the installation of tile.
3) Receives all types of tile or boards.
4) For interior or exterior floors and walls
5) Two-coat system – roller applied
6) Non-bituminous – not an epoxy
7) High strength of bond, high adhesive, excellent in whole waterproof.
8.) Versatile multipurpose waterproofing slurry

USES
1) Use to waterproof all common building substrates that require protection from topside water exposure.

2) Use over interior and exterior concrete and masonry finishes, and over existing tile, drywall, cementitious backer boards and plywood on all interior floors and walls prior to the installation of tile and stone.
3) Also use for exterior balconies and other concrete and masonry surfaces to prevent liquid water from penetrating from the topside through the tile application to the area.

SURFACE PREPARATION
1) K11 Waterproofing Slurry requires a solid substrate that is clean, dry and free of oils, grease, wax, latex compounds, curing compounds, dust and all foreign matter.
2) All building boards must be flat and firmly fixed.
3) Painted surfaces must be scabbled/abraded to expose at least 80% of the original substrate.
4) Terraces, balconies, and swimming pools Cement-based surfaces:
5) Surface cracks should be repaired.
6) Surface should be leveled if there are larger deviations.
Surfaces with existing coatings:
Surfaces with ceramic tiles should be checked for its stability. The surface should be free from dust, dirt, oil etc.
Plastered surfaces:
Cement-based plasters should stay for 14 days before application. The adherence of layers to the surface must be very good, and free from dust or stain.

MIXING
1) Component B (liquid component) is poured into a clean vessel, and component A (powder component) is added, and mixed with a mechanical mixer (350 rpm) until no lump is left.
2) It is recommended to use low cycled (350 r/min) electrical mixer in order to make the mortar homogeneous.

APPLICATION
1) K11 Waterproofing Slurry is applied in two layers. Second layer is applied 4 to 5 hours after application of first layer in the opposite direction (for example, second layer should be applied in horizontal direction if the first layer is applied in vertical direction)
2) The surface must be pre-wetted to saturation and be thoroughly damp, but have no free water on it.

3) On applying the K11 Waterproofing Slurry, the substrate should appear matt, and there should be no signs of glistening water on the surface.
4) The Waterproofing Membrane is applied using a brush, broom or spray machine.

5) Ensure the material is thoroughly mixed before applying.
6) The coating should be applied to the whole surface in at least two coats. A second coat required to obtain a waterproof membrane, and must be applied at a 90° angle to the first coat while the first is still green. In no instance should the total thickness exceed 5mm.
7) The Waterproofing Membrane must not be applied at temperatures below 5°C or on frozen surfaces.
8.) Before applying further coatings, e.g. renders, tile adhesives etc onto Waterproofing Membrane, allow the Waterproofing Membrane to fully cure.
9) Ceramic tiling application may start minimum 12 hours after application of Waterproofing Membrane.
10) The surface must be checked for faults before applying the next coat(e.g. before application of screed)

PRECAUTIONS
1) Do not add cement, or sand to this two component mixture.
2) Product should not be stored at temperatures below +4°C.
3) Product should be applied at ambient temperatures be between +5° and +40°.
4) K11 Waterproofing Slurry should not be exposed to water or rainwater for 24 hours after application.
5) Wait for minimum 7 days to fill water tanks or potable water tanks after application of K11 Waterproofing Slurry, when it is tiled.
6) Air bubbles which are formed during mixing process weaken water proofing.

     Therefore mixture should be prepared using a low cycled mixer.
7) Although it lowers water absorption capacity of surfaces of gypsum plasters, it is not used as a waterproofing material on gypsum boards.
8.) K11 Waterproofing Slurry is a water proofing material used under tile applications.

     It is not used for surfaces exposed to sunlight.
9) Attention should be given to wrapping it up in bundles to the internal surface especially during water tank and swimming pool applications.

10) In case of incomplete wrapping which gives rise to interruptions, there may be water leakages at these points.
11) A net should be used to prevent K11 Waterproofing Slurry from getting damaged at corner points during water tank, swimming pool, terrace, and balcony applications.
12) Since base concrete and side walls are exposed to different loads during construction of water tanks and swimming pools, concrete pouring sequences of base and side walls should conform to the project.
13) A very good insulation should be applied to such part of pipes placed in the mould for discharging water while side concrete are poured for water tanks and swimming pools
14) It is not suitable to use the product as a final coating material.
