Abstract |
This study is on the evaluation of double surface protection method using water repellent primer and final top coat to protect concrete. Water repellent agent has been applied on the final top coat to protect concrete. However, to make up for the weakness to the ultraviolet of the water repellent, the work procedure of these protectors is done vice versa. This combination of protectors was compared with existing ones in this study. Even though the final top coat was applied on the water repellent primer, its adhesive strength met to KS F 4936- 03 with other protectors used in this study. All surface protectors used in this study were excellent in protecting concrete. Especially, in case of applying with final top coat in conjunction with water repellent primer, the resistance against chloride ion penetration and neutralization by CO₂ was more efficient than other surface protectors used in this study under this given condition.
