Grouting is of great importance to ensure aesthetics and durability in ceramic applications. However, incorrect application or environmental factors can lead to cracking and deformation in joint sealants over time. As Barkim Construction Chemicals, we have compiled the main problems encountered in joint sealants and the measures to be taken to prevent them.
Factors Causing Cracking in Joint Sealants
- High absorbency of the surface: Highly absorbent surfaces cause water in the mortar to be rapidly absorbed, leading to cracking.
- Wrong product choice: Choosing a product that is not suitable for the joint width and area of use may cause deformation in the long term.
- Insufficient moisturizing of the surface: Joint sealants applied on dry surfaces may lose their durability by losing water.
- Using the wrong water ratio: Adding too much or too little water adversely affects the strength and integrity of the joint sealant.
- High ambient temperature: Applications in hot weather or in direct sunlight may cause the joint sealant to dry quickly and crack.
- Exposure to wind: The rapid drying process causes the filling material to lose its flexibility and crack.
- Excessive water cleaning: Intensive water wiping after application may weaken the binding properties of the filler.
- Incomplete filling of joints: Incomplete or superficial applications lead to cracking and abrasion of joint sealants over time.
Recommendations for Robust and Durable Joint Sealants
- Product selection should be made according to the joint width and application area.
- The joints should be sufficiently moisturized before application.
- When preparing the joint mortar, the water ratio should be adjusted in accordance with the manufacturer’s instructions.
- Avoid application in extremely hot weather and in direct sunlight.
- After the application is completed, it should be ensured that the surface is not exposed to wind.
- Cleaning should be done gently and without using too much water.
- Ensure that joint sealants are applied completely and evenly.
With the right techniques and appropriate material selection, you can prevent cracking problems in joint fillings and obtain a long-lasting and aesthetic surface. As Barkim Construction Chemicals, we continue to add value to your projects with high quality and durable construction chemicals.
