Abstract
Surface treatment with mortar is necessary to waterproof the ALC tiles when finishing the tiles at the site using organic adhesive. However, to perform such surface treatment with mortar in addition to finishing the tiles using organic adhesive at the site is troublesome, and brings about problems such as not being able to properly mix the mortar and having to perform extra work which is an obstruction to popularizing the method of finishing ALC panels with organic adhesive.Therefore based on the belief that surface treatment using acrylic resin instead of mortar is easier for construction and for quality control of surface treatment, we have conducted various studies using organic adhesive and acrylic resin. As a result, we have found that acrylic resin is as effective as mortar for surface treatment.
