Element to quality
Cement base material (concrete/mortar) must complete structure, and has enough compressive strength (minimum 25 N/mm2), minimum drawing strength is 1.5 N/mm2.
Base material must be clean, dry and does not contain any pollutants, such as dirt, mud, oil, grease, coating, surface treatment and the loose of brittle materials
hybrid
important
Please do not diluted with solvents or water
- Will C agent into B agent barrels
- With bucket stirrer stir thoroughly until the color uniform color resin
- Heating products: A dose of + 67 ° C: agent B + C + 53 ° C
- Mixed with the spray equipment, confirm machine maintain a constant pressure
- Regularly check the accurate mixing and dose of value.Equipment can provide the correct pressure and heating
applied
important
Confined space ventilation
Be sure to confirm in confined Spaces construction products keep ventilation
important
Please do not used for primer or uneven of the base material
Can only be used for a primer or flat surface between concrete and the ground
important
Please do not used for rising above the water
Please do not applied to increase moisture of base material
important
Do not apply to the interpretation of the base material
Important: do not applied in many pores on the surface, due to the applied process will produce obvious phenomenon of moisture vapour transmission (exhaust)
Please use the two components, pneumatic or electric thermal spray multiple equipment construction
Tools to clean
Immediately after construction with Sika ® Thinner C clean all tools and construction of facilities.Construction equipment should be clean and filled with Mesamoll.Hardening of the material can only be removed in mechanical way
