Glass fiber gridding cloth is a common thermal insulation and reinforcement material for modern building exterior walls. The breaking strength and alkali resistance are important properties of constant glass fiber gridding cloth. The breaking strength of glass fiber cloth is inseparable from the number or weight of glass. Domestic product standards require that the weight of glass fiber mesh per square meter should be more than 160g (the mainstream of the market is 120g, with low cost).

In the process of using glass fiber gridding cloth, it is necessary to improve the breaking strength standard. Especially polymer cement plaster with high cement content and cement strength grade. The damage of these things to the glass fiber mesh is not only chemical corrosion, but also the crystallization pressure corrosion of calcium hydroxide and calcium sulphoaluminate. At the same time, the high water absorption of mineral materials also has a negative impact on the glass fiber gridding cloth. The experiment shows that after immersion in distilled water, the strength of glass fiber mesh will be reduced by about 30%.
The cement-free pure polymer plaster mortar has no alkali corrosion and low water absorption. The glass fiber mesh cloth can play its role in it for a long time, which is undoubtedly very safe for the long-term crack resistance of the protective surface.
