1、Self-leveling grout
Hard, durable grout is a common advantage of two-component grout. It offers good hardness, vibrant colors, and long-lasting performance. However, it requires more complex application, and traditional methods often involve using decorative paper. However, by choosing water-based two-component grout, these drawbacks can be overcome.
2、Flexible joint sealant
Flexible fillers are typically single-component flexible joint fillers made of high-molecular-weight nano materials. Their advantages include simple and fast application, but their hardness is lower than that of two-component fillers.
Two. Is harder grout better?
Don't assume that all joint fillers are necessarily the harder, the better. The best joint fillers should strike a balance between hardness and flexibility, possessing the strength of iron while also maintaining good elasticity.
"The gap left between tiles is to prevent tile cracking, as everyone understands the principle of thermal expansion and contraction. Now that everyone has seen ready-mixed joint fillers, homeowners who purchase them, especially those who have paid close attention to the advertising slogans of suppliers, may be wondering: if ready-mixed joint fillers are as hard as tiles, wouldn't they still crack due to thermal expansion and contraction? It's important to note that ready-mixed joint fillers don't necessarily need to be as hard as tiles; instead, they need to have good elasticity and the ability to return to their original shape after being pressed. This type of ready-mixed joint filler is the best."
