What exactly are the stone adhesives?
Engineered Specifically for Natural Stone. Formulated with advanced polymer-modified cement technology, our stone adhesives deliver uncompromising bond strength and long-term structural durability. High-thixotropy, zero-vertical-slip performance holds heavy stone cladding firmly in place on walls, while specialized grades offer either Extended Open Time for intricate, large-format installations or Rapid Setting for fast-track projects and moisture-sensitive stones.

| Property | Technical Mechanism | Standard Code (ISO 13007 / EN 12004) | On-Site Benefit for Natural Stone |
|---|---|---|---|
| Polymer Content in Cement | Redispersible polymer powders (EVA/acrylic) form flexible polymer films throughout the cement matrix | C2 (Improved Adhesion>1.0 N/mm^2 & S1 / S2 (Deformable) (Deformable) (Deformable) | Absorbs differential thermal expansion and structural vibration between the substrate and dense stone without cracking or debonding. |
| No Vertical Slip | Thixotropic rheology modifiers increase yield stress when shear ceases | T (Slip<0.5 mm))) | Allows installers to hang heavy granite, slate, or travertine wall cladding top-down without spacers bearing the full dead load. |
| Extended Setting / Open Time | Water-retaining cellulose ethers slow down surface skinning and evaporation | E (Extended Open Time> 30 mins) | Crucial in hot, dry, or windy climates and when double-buttering large-format slabs where adjustments take longer. |
| Fast Setting Time | Rapid-hydrating aluminate cements bind free mix water chemically within hours | F (Early Tensile Strength >0.5 N/mm^2 in 6 hrs)in 6 hrs)in 6 hrs) | Prevents moisture-sensitive stones (green marble, resin-backed stone, agglomerates) from absorbing water, cupping, warping, or discoloring. |
Uses
Non-Staining White Cement Base (Efflorescence Control): Translucent and light-colored stones like Carrara marble, Onyx, and white limestone act like sponges. Highlighting a White Base formulation with low free-alkali content assures buyers that grey cement pigments and soluble salts won't bleed through to the surface of expensive stone.
Thicker Bed Capability (Medium/Thick Bed up to 15–20 mm): Unlike factory-calibrated ceramic tiles, natural stone often has slight thickness variations or cleft backs. Mentioning zero-shrinkage thick-bed capability tells contractors they can level uneven stone backs without hollow spots or curing shrinkage.
