Tiling a balcony. Building a pool. Securing large format tiles over a waterproofing membrane. Gripset C-Lite delivers the C2TES2 performance these demanding environments require. It ensures secure, flexible adhesion where substrate movement, water immersion, or thermal cycling challenge standard adhesives.
Gripset C-Lite is a premium-grade, highly flexible, and non-slump cementitious tile adhesive engineered for long-term durability. It provides exceptional versatility across critical tiling applications. This formulation prevents tile debonding and cracking, ensuring resilient performance where thermal expansion, substrate movement, or water immersion are constant factors.
Mixing is straightforward: add 4.5 litres of clean water to each 15kg bag of C-Lite while stirring until a smooth, lump-free consistency is achieved. Allow a 3-minute stand time before re-stirring and application. Apply the adhesive using an appropriately sized notched trowel. For tiles larger than 300 x 300mm, back-buttering the tile is essential to ensure full adhesive coverage and prevent voids. The 30-minute open time allows efficient placement, and tiles can be adjusted for up to 40 minutes. Tiling should follow AS 3958 standards, including provisions for movement joints. Grouting can begin after 24 hours. Tools clean easily with water while the adhesive is wet.
For highly porous surfaces, priming with Gripset GP Primer is recommended. For non-porous surfaces, use Gripset OP Primer to optimise adhesion.
Gripset C-Lite is a reliable choice for challenging environments where long-term tile adhesion is paramount:
Gripset C-Lite typically functions as the direct tile adhesive layer in high-performance waterproofing systems. In a tiled pool build-up, it is applied after the application of Gripset Elastoproof collars and the Gripset 2P cementitious membrane, providing the critical bond for tiles directly over the waterproof layer. Similarly, for external balconies and wet areas, C-Lite secures tiles over approved waterproofing membranes like Everflex Aqua-Ban Waterproofing Membrane. Its role is to securely bond tiles while maintaining the system's flexibility and water resistance, forming the final structural layer before grouting.
Gripset C-Lite delivers premium, highly flexible (S2), non-slump (T) performance for the most demanding internal and external tiling jobs, including large format tiles, wet areas, immersed conditions, and over Gripset waterproofing membranes. It provides the highest level of assurance against movement and environmental stress. In contrast, consider Gripset C-Mastic for applications requiring a C2TE adhesive, which offers excellent adhesion and extended open time but with a standard level of flexibility. C-Mastic is suitable for general internal and external wall and floor tiling where the extreme flexibility of an S2 rated adhesive is not explicitly required.
Yes, Gripset C-Lite is suitable for immersed applications like pools, spas, and water features. It achieves a tensile adhesion strength of ≥1 MPa after water immersion, ensuring a durable bond in these demanding environments.
C2TES2 means Gripset C-Lite is a high-performance, cementitious adhesive with improved characteristics, an extended open time, and high deformability. This classification confirms its suitability for challenging installations like large format tiles and areas subject to movement.
No, Gripset C-Lite is not recommended for direct fixing onto timber floors. Refer to Gripset technical guidelines for alternative solutions for timber substrates.
For tiles larger than 300 x 300mm, back-butter the tiles in addition to notching the substrate. This ensures full adhesive coverage and prevents voids, which is critical for the long-term performance of large format installations.
| Application | Key benefit | Primary trades |

| Wet areas, including showers and bathrooms | Achieves ≥1 MPa tensile adhesion after water immersion, ensuring long-term durability. | Waterproofers, Tilers |
| Immersed applications (pools, spas, water features) | Maintains critical bond integrity in constant water exposure with 7-day cure for service. | Pool builders, Tilers |
| Large format tile installations | High flexibility (S2 classification) and non-slump properties reduce tile lippage and stress cracks. | Tilers |
| Tiling over early age concrete, render, and screeds | Formulated to accommodate residual moisture and movement in new construction with reduced waiting times. | Builders, Tilers |
| Underfloor heating systems | High deformability (S2) accommodates thermal expansion and contraction cycles without bond failure. | Tilers, Floor heating installers |
Ensure all substrates are clean, sound, smooth, dry, and free from contaminants such as dust, oil, grease, wax, moss, or laitance. Mechanically remove unsound layers and ensure surfaces meet relevant Australian Standards (AS 3958).
Prime with Gripset GP Primer at 1 L per 8–10 m².
Prime with Gripset OP Primer at 1 L per 12 m².
Mix 15 kg of Gripset C-Lite with 4.5 L of clean water in a clean pail. Add powder to water while stirring continuously with an electric stirrer and paddle attachment until smooth and lump-free.
Mix for 2–3 minutes, allow to stand for 3 minutes, then re-stir before use.
For smaller areas, proportion mix ratio accurately to maintain performance consistency.
Apply adhesive with a notched trowel suited to tile size. For tiles larger than 300 × 300 mm, back-butter the tile in addition to notching the substrate.
Spread no more than 1 m² at a time to prevent premature skinning.
Use 12–20 mm notch trowels and ensure adhesive coverage meets AS 3958 standards.
Allow adhesive to cure for 24 hours before grouting. Ensure all adhesive residue is removed from joints before grout application.
Grout only when tiles are firmly set and will not be displaced.
Protect from rain for 24 hours after grouting; allow 3–4 days before wet area service and 7 days before immersion.
Danger: Gripset C-Lite causes skin irritation, serious eye damage, and may cause respiratory irritation.
Wear safety shoes, overalls, nitrile rubber gloves, safety glasses, and a dust mask. Ensure all PPE is suitable for the work and identified hazards.
Use only outdoors or in a well-ventilated area. Ensure ventilation is adequate to maintain air concentrations below exposure standards, and avoid generating dust.
Store in a cool, dry, well-ventilated place out of direct sunlight. Keep container tightly closed and store locked up. Shelf life is 12 months in original unopened packaging. Dispose of contents/container in accordance with local regulations.
Proper substrate preparation is critical for adhesion and system longevity. Ensure all surfaces are clean, sound, dry, and free from contaminants that could compromise the bond.
Surface prep: Allow concrete slabs to cure for at least seven days, with a minimum compressive strength of 20MPa and a wood float finish. Steel-trowelled, burnished, or dense concrete must be mechanically abraded to roughen the surface and provide a key.
Primer: Optional. For abraded, dense concrete, prime with Gripset OP Primer.
Surface prep: Allow rendered and screeded surfaces to cure for at least 24 hours.
Primer: Required for highly porous surfaces. Apply Gripset GP Primer at 1 litre/8-10m².
Surface prep: Ensure existing tiles are well bonded, sound, and secure. Mechanically abrade or roughen the tile surface to remove at least 80% of the glaze for direct fixing.
Primer: Optional. Alternatively, prime tiled surfaces with Gripset OP Primer at 1 litre per 12m².
Surface prep: Ensure membranes are fully cured and clean as per their specific data sheets.
Primer: Not required.
