DESCRIPTION
CEM-KOTE BARRIER COTE 100 is a high performance, heavy duty waterproofing cement coating – thin topping.  It is designed for a variety of uses in waterproofing, resurfacing of high traffic areas, or areas with high impact or abrasion resistance requirements such as in parking garages, industrial floors, loading docks and many others. CEM-KOTE BARRIER COTE 100 is also used as a bonding agent in applications when dealing with highly contaminated concrete, including oil contaminated concrete.  In these applications a special methodology is required.  Contact Technical Services for further information.  It can also be used in negative and positive side waterproofing and in chemical protection of concrete.  An additional unique application includes the use of CEM-KOTE BARRIER COTE 100 as a water vapour retarder in application on concrete slabs exhibiting a high water vapour transfer.  When dealing with dynamic (moving) substrate cracks, CEM-KOTE FLEX PLUS reinforced with the REINFORCING FABRIC HD is applied over the crack prior to the application of CEM-KOTE BARRIER COTE 100, to provide crack bridging.  In some instances, the crack is routed out and filled with GEM-KOTE EP ST epoxy mortar.  Contact Technical Service prior to preparation of specification or use for further information regarding the use of this product.  The applicator must, prior to bidding a project, confirm the details of surface preparation and detailing with Technical Services.

Composition and Materials
CEM-KOTE BARRIER COTE 100 is a high performance, Portland cement based material.  It is a two component system consisting of dry powder blend (Component A) and a liquid additive, (Component B).  For additional tensile strength and crack bridging, it is reinforced with the REINFORCING FABRIC HD.  CEM-KOTE BARRIER COTE 100 exhibits an excellent bond to clean, structurally sound concrete, substrate crack spanning, weather and freeze/thaw resistance. CEM-KOTE BARRIER COTE 100 is mixed on site and applied by trowelling, spraying or brushing.

Limitations
Do not apply CEM-KOTE BARRIER COTE 100 when the temperature is expected to be below 4ºC (40ºF) within 48 hours or when rain is imminent.  Follow “hot concreting” procedures when applying CEM-KOTE BARRIER COTE 100 at temperatures exceeding 25ºC (77ºF).  The proper surface preparation is essential for a successful concrete repair using CEM-KOTE BARRIER COTE 100.  Consult Technical Services before starting a project to ensure that correct surface preparation and application procedures are followed.

Health and Safety
CEM-KOTE BARRIER COTE 100 is non-toxic. Your skin might be sensitive to hydraulic cement or the liquid additive.  We recommend use of rubber gloves.  Avoid contact with eyes and prolonged contact with skin.  If contact occurs, flush immediately with water.  Seek medical advice if irritation occurs.  Harmful if digested.  Keep product out of reach of children.  FOR INDUSTRIAL USE ONLY.  Consult MSDS for additional information.

Colour
CEM-KOTE BARRIER COTE 100 is available in industrial grey.

Packaging
CEM-KOTE BARRIER COTE 100, Component A is a dry material packaged in 22.7 kg (50 lbs.) paper bag.  The Component B, 5.9 litres (1.55 gallon U.S.) is a liquid additive, packaged in a plastic container.

Yield
The theoretical coverage of CEM-KOTE BARRIER COTE 100 is 8.73 m² (93.89 ft²) at 1.6 mm (64 mils) thickness; 6.98 m² (75.12 ft²) at 2 mm (80 mils).  The typical thickness is approximately 1.6-2 mm.  The actual coverage will depend on surface roughness and the thickness applied.  When used as bonding agent, the typical coverage is 20 m² (200 ft²) per unit, but it can vary considerably depending upon the surface roughness and porosity.  The applicator must, in each case, carry out a sample application to determine the actual coverage for the given substrate and application thickness.

Storage and Transportation
When stored in dry area, the material has a shelf life of 12 months.  The liquid component B must not freeze.

INSTALLATION
Mixing
Mix the content of the bag, 22.7 kg (50 lbs.), component A with the liquid component B.  Use clean standard paddle or helix screw type mixer or heavy duty drill (400-600 rpm) with a mixing paddle.  Pour approximately 80% of the liquid component B into the mixing container (mixer) and gradually add the dry material into the liquid and mix until a smooth and lump-free mix is obtained.  Lumps will form if the dry material is added suddenly into the liquid.  Depending on application, add the remaining liquid as required for a given application consistency.  A small amount of water can be added if required at higher ambient temperatures.

Application
Remove all deteriorated concrete.  Remove all loose and oil or grease contaminated concrete laitance, dust, dirt and efflorescence.  Clean the surface using dry or wet sandblast, shotblast, high pressure water.  Repair deeper areas using GEM-PLAST TC or FIBRE-PATCH.  Pre-fill all the cracks with CEM-KOTE FLEX PLUS.

Contact Technical Service for detail surface preparation instructions.  Apply CEM-KOTE BARRIER COTE 100 to a saturated surface dry (SSD) or saturated surface “damp” surface.  Trowel or brush apply 1.6 to 3 mm (1/16 to 1/8″) thick layer in two coats.  When applying the REINFORCING FABRIC HD, apply first a thin layer of material by brush or spraying.  When using spraying, brush the coats to eliminate all the “pin holes”.  Embed the REINFORCING FABRIC HD into the first coat and follow with the second coat, brush or spray again; when using spraying, brush the layer.  Make the surface smooth, free of wrinkles.  The fabric must be just covered by the cement material; it must not protrude through the surface.  This is especially important in applications where the smooth surface is required to minimize the solids “pick up”, e.g. in the waste water treatment facilities.  Typically the minimum thickness of this application is 2 mm, including the REINFORCING FABRIC HD.  Cure CEM-KOTE BARRIER COTE 100 by air drying.  The material must be air dry cured for a minimum 3 days prior to a continuous exposure to water.  Protect fresh applications from rain, strong wind and intense sunlight for 12 hours.  When working under tarps at freezing temperatures, avoid using propane heaters; the electrical heaters must be used to prevent “carbonation” of the material.

WARRANTY
