Step by step

CJ Seal application temperature shall be between 5°C and 50°C. Application procedures may slightly vary depending on site conditions. The general recommended guidelines for the application of the sealant coating, as follows.

SURFACE PREPARATION

The surface to receive the sealant shall be clean and free from sharp protrusions. Clean thorough of all contaminants like dust, traces of curing compound, oil and grease and where necessary a suitable wire brushing / mechanical means shall be involved. All surface imperfections, protrusions, structurally unsound and friable concrete shall be removed and repaired with a suitable Polycrete concrete repair mortar. 

MIXING AND APPLICATION

CJ Seal is supplied in pre-weighed three-part packs, which only requires on site mixing. Mix Part A and Part B separately for a minute, if required, with a slow speed drill (300-400 rpm) fitted to a flat bladed paddle. Add component B to A and mix thoroughly for 1-2 minutes. Add slowly Component C into the mixture and further mix for another for 2-3 minutes, till a uniform and homogenous consistency is achieved. The mixed product is suitable for application in horizontal areas and can be applied at thickness of up to 10 mm in vertical areas, with multiple layers possibility. Please follow the method statement for detailed application instructions.

Note: All parts are pre-weighed and hence, no part mixing shall be practiced.

CLEANING

Remove all excess sealant with a scrapper. Any spillage can be cleaned using Polysolvent. Clean all tools and equipment using similar solvent immediately after the tooling. Hardened materials can only be removed by mechanical means.
