How to use
Substrate preparation
The surfaces to be coated should be clean, sound, and free from 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. Substrate containing honey combing, damaged or deteriorated concrete should be repaired using suitable repair mortars from KINGKRETE repair systems before coating.
Priming
No special primer is required, but substrate should be pre-soaked with clean water prior to application of KingPlast DCM100.
Mixing
To ensure proper mixing, a mechanically powered mixer or drill fitted with suitable paddle should be used.
Add the liquid component of KingPlast DCM100 to a clean container. The powder component 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
KingPlast DCM100 can be easily sprayed and also can be applied by brush. The mixed material should be sprayed well into the surface. Care must be taken not to spread the materials too thin. The first coat should be applied at a wet film thickness of 1 mm.
When the material begins to drag, do not add any water, but dampen the surface again.
A minimum of 2 - 5 hours, depending on the prevailing ambient temperature, should be given for the first coat to cure before applying the second coat.
For brush applications, the second coat should be applied in a perpendicular direction to the previous layer to ensure good bond and coverage. To achieve a smooth finish, it is recommended to finish the surface with a trowel immediately after brushing the second coat. The total dry film thickness for both coats should be 2 mm.
REMARKS
KingPlast DCM100 should not be applied to frozen substrates or if ambient temperature is below 5°C or expected to fall below 5°C.
Cleaning
All tools shall be cleaned immediately after application using fresh water. Hardened materials must be cleaned mechanically.
