One, why is there a gap left when using wall stone?
1、 Aesthetic factors
When installing wall stone, it is recommended to leave gaps to effectively prevent unevenness and misalignment during on-site construction, which can occur due to various reasons. This will also help to mitigate issues caused by color variations in the stone itself. After leaving the gaps, the color variations will be significantly reduced, unlike tight seams where they are more noticeable.
2、Construction factors
After creating expansion joints, large-scale stone installation becomes more convenient and faster. Furthermore, the dry-hanging stone installation method, which utilizes expansion joints, is less prone to quality issues.
Two. How to handle stone with seams
1、Clean the interior of the stone joints thoroughly, ensuring no large stones remain, and maintain a dry environment.
2、Pour the appropriate amount of waterproof adhesive and use tools to completely penetrate the adhesive into the gaps.
3. Apply the joint sealant evenly, carefully fill the joints with a tool, and then wipe the edges of the joints with a cloth to remove any excess sealant. After waiting for three hours, walk on the stone. Note: Stone is prone to contamination and requires regular cleaning with a damp cloth containing a mild detergent.
