Why you should use silicone over siliconized acrylic

When it comes to expansion joints in showers, using 100% silicone is generally preferred over siliconized acrylic for several reasons:

1. Waterproofing: 100% silicone offers superior water resistance compared to siliconized acrylic. Silicone creates a watertight seal that helps prevent water from seeping into the joints, protecting the underlying structure and preventing potential water damage.
2. Flexibility: Expansion joints are subjected to movement and temperature variations, and silicone has excellent flexibility and elasticity. It can accommodate joint expansion and contraction without cracking or losing its sealing properties. Siliconized acrylic, on the other hand, is less flexible and may not be able to withstand movement as effectively, leading to potential leaks over time.
3. Durability: Silicone is known for its durability and long-lasting performance. It can maintain its sealing properties for an extended period, even in high-moisture environments like showers. Siliconized acrylic may not have the same level of durability and may degrade or lose its effectiveness over time, resulting in the need for more frequent repairs or reapplication.
4. Mold and Mildew Resistance: Silicone has inherent resistance to mold and mildew growth. It discourages the development of these unsightly and potentially harmful substances in the joints. Siliconized acrylic may be more prone to mold and mildew growth, especially in areas exposed to high humidity and moisture, requiring regular cleaning and maintenance.
5. Aesthetics: 100% silicone generally provides a smoother and more professional finish compared to siliconized acrylic. It has excellent adhesion and can create a seamless appearance in the expansion joints, enhancing the overall aesthetic appeal of the shower.
