How to use
Substrate preparation
The surfaces to be coated should be clean, sound, and free from any contamination. Remove any traces of curing compound, laitance, organic growth or any other loose materials. This is best obtained by using high pressure water or light grit blasting.
Honey combing, damaged or deteriorated concrete exists, the substrate should be repaired using suitable low permeability repair mortar from KINGKRETE repair systems before commencing the coating.
Priming
No primer is required, but substrates should be pre- soaked with clean water prior to application of KingProof C2000.
Mixing
To ensure proper mixing, a mechanically powered mixer or drill fitted with suitable paddle should be used. The 5 kg of KingProof C2000 liquid should be added to a clean container. The 10 kg powder is then added slowly to the liquid while mixing continuously with low speed mixer/ drill (400 - 600 rpm). Mixing time should be continued for 3 minutes until a uniform consistency is obtained.
Application
KingProof C2000 can be applied by brush or spray. The mixed material should be brushed well into the surface. Strike off with the brush in one direction. Care must be taken not to spread the material too thin. When the material begins to drag, do not add any water, but dampen the surface again. Leave the first coat overnight to cure before applying the second coat. The second coat shall be applied by brush in a similar way to the first layer but preferably perpendicular to the previous layer to ensure good bond and coverage.
Areas subjected to foot traffic fibreglass mesh (2*2) needs to be installed between the two coats of KingProof C2000. For spray application, a maximum of 1 litre of water may be added to the mix if needed depending on the type of spray machine.
REMARKS
KingProof C2000 should not be applied to frozen substrate or if ambient temperature is below 5°C or expected to fall below 5°C.
Cleaning
All tools should be cleaned immediately after finishing by clean water. Hardened materials should be cleaned mechanically.
Coverage, packaging and storage
Coverage
Approximately 8.5 - 9 m² for 1 mm thickness.
Packaging
KingProof C2000 is available as 15 kg packs (5 kg polymer & 10 kg powder).
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
Health and safety
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs. Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation.
