Development and application of organic surface preparation materials for exterior wall tiling with organic adhesives

Exterior wall tiling using organic adhesives is expected to prevent tiles from separation because of its high elasticity, but generally mortar with poor elasticity has been used to smoothen irregularities of the concrete surface. We have developed an organic surface preparation material with higher elasticity than mortar, so that the tile layer could consist of all elastic materials. Various tests were carried out to evaluate mechanical properties and durability of the surface preparation material and the tiles adhered using this method. Test results showed that the material had enough strength and elasticity to meet JIS A 5557 criterion value. Test results also proved that the tiling had adequate deformational and fatigue property to improve the separation prevention performance.
