One、Should microcrystalline stone leave a gap?
Please leave a gap.
When laying microcrystalline stone, it is important to leave gaps for both aesthetic purposes and to prevent future cracking, deformation, or air pockets.
Two. What is the appropriate size for micro-crystal gaps?
Micro-crystalline stone laying with a gap of 1.5-2mm (for reference only).
Three. How to fill the micro-pore cracks.
1、Filling gaps with sealant
The main component of the joint filler is primarily white cement, with some inorganic pigments added. The whiteness is approximately 86%, and the surface strength is slightly higher than that of white cement. Using this joint filler to fill the gaps between microcrystalline porcelain tiles can provide wear resistance and pressure resistance, and it is also relatively inexpensive. However, the color of the joint filler is relatively dark, and it is prone to becoming dirty during construction and use. Additionally, its strength is also relatively low.
2、Filling with joint filler
Epoxy grout is a new type of organic material, primarily composed of high-tech polymer resins, high-grade pigments, and special additives. It has a whiteness of approximately 95%, high surface strength, and good flexibility. When epoxy grout is used to fill the joints between micro-crystal tiles, it creates a vibrant and glossy appearance, and also offers waterproof, anti-permeation, and oil-repellent properties. However, epoxy grout has a relatively low hardness and a thin protective layer, and it is also more expensive than traditional grout.
