Flexible Stone (soft ceramic panels) requires the right adhesive to ensure durability, aesthetic appeal, and long-term performance. This guide provides a clear comparison of the main adhesive options and practical installation tips.
| Adhesive Type | Form | Mixing / Use | Coverage / Quantity | Pros | Cons | Recommended Use |
| Two-Component Epoxy Resin | Powder + Liquid | Mix 80% powder + 20% liquid, no water | ~2 kg/m², full coverage (≥90%) | Strong bonding, durable, professional finish | Requires skill, time-consuming, sensitive to temperature | Interior & exterior, large/heavy panels, long-term projects |
| Tile Adhesive | Powder (mix with water 1:4) | Stir 5–6 hours, use promptly | 3–4 kg/m², full coverage (≥90%) | Convenient, export-friendly, widely available | Slightly less durable than epoxy | Interior & exterior, export projects, general installations |
| Structural Silicone Adhesive | Pre-filled cartridge | Spot application, use with caulking gun | Based on spot size | Quick, easy, minimal skill needed | Not durable, may cause bulging, not for exterior | Temporary interior installations or display areas |
Substrate must be flat, solid, and clean
Remove dust, grease, and standing water
Waterproofing is required for wet areas or exterior walls
Smooth surfaces (tiles, steel) should be roughened, primed, or mesh-reinforced
Large/heavy panels (≥1200×2400 mm) require a row of nails on the upper half only
Avoid nailing in the middle/lower section to prevent slipping or hollow spots
Interior: Leave 1–2 mm micro-gaps, optional to fill
Exterior:
Small panels: 8–10 mm gap
Medium panels: 6–8 mm gap
Fill with appropriate grout for waterproofing
Remove excess adhesive after drying with a troweland semi-dry sponge
Do not wet-clean immediately, to prevent white streaks
| Adhesive | Working Time | Curing Time |
| Two-Component Epoxy | ~2 hours | ~24 hours (faster in warm, slower in cold/humid) |
| Tile Adhesive | 5–6 hours (hot weather may shorten) | ~24 hours |
| Structural Silicone | Quick setting | N/A (temporary use) |
Professional choice: Two-component epoxy resin for long-lasting, durable installations.
Convenient alternative: Tile adhesive for export projects and general installations.
Limited use: Structural silicone only for temporary interior applications.
Tip: Full adhesive coverage (≥90%) is essential for proper bonding, especially for large or heavy panels.
