USES
CHEM-BOND CCC550 can be used as bonding admixture to mortar or cement formula or used as surface bonding primer on existing area to be patched with cementitious repair mortar compounds. In basic lime mortars, compressive strengths will increase when CHEM-BOND CCC550 is used as an admixture, especially effective on mortar joints on windowsills.
APPLICATION
Surface Preparation: when used as a contact bonding material, always make sure that the surface is completely clean and free from pounded water. If the existing surface is a hard troweled concrete, then etching is recommended prior to the application.
Limitations: CHEM-BOND CCC550 is a temperature sensitive material. Store at temperatures between 2°C and 32°C.
Coverage: Varies depending on application and conditions of base concrete, etc…. As a primer, 4.9 m2 per liter in brush application.
Application as Bonding Agent:
- Apply generous amounts of CHEM-BOND CCC550 with a roller or brush to the existing moist surfaces that are to receive fresh cementitious materials.
- Allow first coat application to dry.
- Apply a second application immediately prior to placing cementitious material.
- Place the cementitious repair mortars, plasters within tack-free time (approx. 10-15 min.).
Application as Admixture/Cement:
- Mix the cementitious material per standard procedures.
- While mixing, add 4.2 lt. of CHEM-BOND CCC550 to each 25 kg of type I Portland cement used in the formula (approximately 8.4 lt. of Chem-Bond CCC550 to each 50 kg. bag of Type I Portland cement used).
- Allow at least an additional five minutes of mixing after the addition of CHEM-BOND CCC550 to ensure complete blending.
- Apply blended material to the primed substrate as per standard procedures.
Application as Plaster/Admixture/Gunite:
- Pre-mix a solution containing 12 parts of water to 1 part of CHEM-BOND CCC550 and blend thoroughly.
- Mix approximately 91 kg. of the plaster material per standard procedures with the solution as pre-mixed above. Adjust amount of plaster materials as required for desired consistency and/or slump.
- Use mixed material in standard procedure.
Curing: Curing of mortars, plasters, etc. made of CHEM-BOND CCC550, must observe standard concrete curing methods.
Cleaning: clean application tools and mixing equipment, etc. with water immediately following use.
