Grouting is a crucial step in the installation of Flexible Stone (soft ceramic panels), as it not only enhances the overall aesthetic but also provides water resistance and structural stability. Proper selection of grout material and careful application ensure a high-quality finish that lasts. This article outlines the best practices for grouting Flexible Stone.
The right grout is essential for both appearance and durability. Flexible Stone requires grout that can adhere well to the panel edges and resist cracking, water infiltration, and discoloration.
Standard Tile Grout: Suitable for general installations; available in cement-based or polymer-modified formulations.
Flexible Stone-Specific Grout: Designed for high-quality wall panels, often incorporating polymers for added adhesion and water resistance.
Composition:
Inorganic silicates (cementitious base)
High-quality imported polymers
Pigments for color consistency
Available Colors:
White, light gray, dark gray, black
Custom colors possible for orders over 500 kg (small orders may incur additional cost)
Packaging: 25 kg per bag
Ensure the adhesive has fully cured:
Wait at least 48 hours after panel installation before grouting.
In humid or wet environments, extend the waiting period as needed.
Clean the joint area:
Remove dust, debris, or adhesive overflow before grouting.
Ensure the panel edges are dry and free from loose particles.
Tip: For interior applications, use masking tape or protective film along the panel edges to prevent grout from staining the surface.
Combine the grout powder with clean water according to the manufacturer’s instructions.
Mix to a smooth, paste-like consistency without lumps.
Avoid adding water after mixing, as this can reduce adhesion and cause efflorescence.
Fill the gaps with a grout bag, trowel, or spatula, depending on joint width.
Ensure complete filling of each joint without voids.
Allow the grout to partially dry (semi-dry) before smoothing.
Use a grout float or tool to smooth the surface.
Remove excess grout carefully to avoid scratching or staining the panel.
Sweep away debris once semi-dry.
| Application | Panel Size | Recommended Gap | Notes |
|---|---|---|---|
| Interior | Any | 1–2 mm (optional to fill) | Micro-gaps give a natural look; filling is optional |
| Exterior | Small panels | 8–10 mm | Fill with grout to ensure waterproofing |
| Exterior | Medium panels | 6–8 mm | Adjust based on design preference; larger gaps enhance 3D visual effect |
Allow the grout to cure according to manufacturer instructions (typically 40 minutes to 2 hours for semi-dry, depending on temperature and substrate).
Protect grouted surfaces from water and heavy contact until fully set.
Avoid wetting the grout during initial curing to prevent efflorescence or streaks.
Grouting before adhesive has fully cured
Adding extra water to the grout mix during application
Leaving gaps incompletely filled
Cleaning grout with excessive water before partial drying
Following proper procedures will prevent these issues and ensure a neat, durable finish.
Grouting Flexible Stone requires careful attention to material selection, joint preparation, and application technique. Using high-quality grout, maintaining proper joint width, and allowing sufficient curing time ensures a beautiful, durable installation.
