Research & Application of the Cracking Resistance Test Method of Base-Coat & Render

The cracking resistance of base-coat & render are important for ETICS. The current cracking resistance test method can not correctly characterize the cracking resistance of base-coat & render. The suitability of the self-developed test method for cracking resistance and the existing methods was studied and compared. The results show: the value of the ultra flexural-displacement by the new test method is more suitable for representing the cracking resistance performance than the impact resistance, the ratio of compressive/flexural strength, the tensile strength, the transverse deformation. The new test method developed by ourselves can directly compared the correlation between mesh specimens and non-mesh specimens, accurately test the effect of fiberglass mesh in the render. The value of the ultra flexural-displacement of base-coat is nearly linear positive correlation with the amount of the VAE emulsion powder in the base-coat. The fiberglass mesh is important for the render cracking resistance. The position of the mesh in the render can significantly influence the render cracking resistance. As the sample with mesh in fixed position, whether cracking is mainly depend on the base-coat, whereas whether breaking is mainly depend on the mesh. The research results have provided a direct basis for the establishment of relevant standards; should be helpful to solve the industry problem that the surface of ETICS engineering is easy to crack.
