One
水泥灰浆类
Cement mortar
水泥灰浆类适用于结构比较稳定的部位,其无毒无害无污染,可以直接在混凝土表面施工,并且粘结牢固,施工两小时之后就可以在上面直接铺贴瓷砖。缺点是成膜后缺乏弹性,会因为建筑的错位或沉降而影响防水性能。
Cement mortar is suitable for the parts with relatively stable structure. It is non-toxic, harmless and pollution-free. It can be directly constructed on the surface of concrete, and the bond is firm. After two hours of construction, tile can be directly laid on it. The disadvantage is the lack of elasticity after film forming, which will affect the waterproofing performance because of the dislocation or settlement of the building.

聚氨酯类
Polyurethanes
聚氨酯类在室内外都可使用,涂刷完厚度较厚约3毫米,弹张力在300%以上,基材的开裂都不会使其开裂,因此其防水性能是最好的。缺点是气味大、不环保。
Polyurethane can be used both indoors and outdoors. The thickness of the coating is about 3mm, and the elastic tension is over 300%. The cracking of the base material will not cause it to crack, so its waterproof performance is the best. The disadvantage is that it smells big and is not environmentally friendly.

JS防水涂料
JS waterproof coating
JS防水涂料是一种刚柔并济的双组份防水材料,环保、无毒、无味、透气性好,与基面粘结牢固并且干燥快。缺点是抗紫外线较差,只适用于卫生间、地下室。
JS waterproof coating is a kind of rigid and flexible two-component waterproof material. It is environmentally friendly, non-toxic, odorless, good air permeability, strong bonding with the base and fast drying. The disadvantage is that the anti-ultraviolet radiation is poor, only suitable for bathroom and basement.
丙烯酸类
acrylic
丙烯酸类是纯液体,无毒、无害、不可燃、开盖即用,可溶于水,易于墙面裂缝结合,形成坚固的防水层,性能特点比较稳定,应用效果比较理想,价格也比较友好,因此在装修防水工程中比较常见。
Acrylic acid is pure liquid, non-toxic, harmless, non-flammable, ready-to-use, soluble in water, easy to crack the wall, forming a solid waterproof layer, the performance characteristics are relatively stable, the application effect is ideal, the price is friendly, so it is more common in decoration waterproof engineering.
