The long-term durability evaluation for acrylic rubber-type waterproofing Membrane coating for exterior wall with actual construction coating film

Abstract

Acrylic Rubber-Type waterproofing membrane coating for exterior wall that confers waterproof, is one of effective finish material for building of the steel reinforced concrete.However, the deterioration by the aging of waterproofing membrane coating for exterior wall progresses, and waterproof elastic performance is reduced.So from the results of a survey of the actual construction coating, long-time high performance of waterproof membrane coating for exterior walls could be confirmed.Further, it is considered that the influence of the topcoat material is also large in order to maintain the performance of waterproof membrane coating for exterior wall.Therefore the long-term durability evaluation by the accelerated weathering test was carried out and was able to confirm the superiority of acrylic silicone resin paint.It will be determined that the waterproofing membrane coating material for exterior wall is effective for extension of life of the building.
