In tropical countries such as Sri Lanka, wall care putties are applied as primers in building constructions providing a smooth shield for the wall. This research study was conducted to investigate the durability performance in terms of rain surface erosion and the bonding strength by shear testing of different wall care putty materials along with walling materials. Four types of walling materials and ten types of wall care putty mixtures were selected. Accelerated erosion test and lap shear strength test were conducted and bond breaking patterns were examined. X-ray diffraction analysis was conducted to investigate the chemical compositions of putty mixtures. Results demonstrate that cement block walling material and putty C+10% cement wall care putty mixture have the highest bonding strength. Similarly, cement added putty mixtures showed higher durability and bonding strength than putty in its pure form.

在斯里兰卡等热带国家，墙面腻子被用作建筑结构中的底漆，为墙面提供平滑的防护。这项研究旨在通过对不同的墙面腻子材料和墙面材料进行剪切测试来研究雨水表面侵蚀和粘结强度方面的耐久性能。选择了四种墙壁材料和十种墙壁腻子混合物。进行了加速腐蚀试验和搭接剪切强度试验，并检查了粘结破坏模式。进行X射线衍射分析以研究腻子混合物的化学组成。结果表明，水泥砌块墙体材料和腻子C + 10％水泥墙面护理腻子混合物具有最高的粘结强度。同样，
