Gripset C-Lite is a commercial-grade tile adhesive designed for high-stress environments including swimming pools, external facades, and large-format installations. This white, C2TES2 classified formula provides S2 high flexibility and non-slump properties, ensuring maximum movement tolerance and bond integrity over early age concrete or heated slabs.
Engineered to exceed ISO 13007 standards, it eliminates common risks of tile lippage and adhesive failure in submerged aquatic facilities and high-traffic commercial zones.
Frequently Asked Questions
Can Gripset C-Lite be used for tiling over freshly poured concrete?
Yes. Gripset C-Lite is suitable for use over early age concrete provided it has cured for at least 7 days, has a wood float finish, and a compressive strength of ≥20 MPa. Ensure the surface is clean and primed as required.
What trowel size should I use for large-format tiles with Gripset C-Lite?
For tiles larger than 300 × 300 mm, use a 12–20 mm notch trowel and back-butter the tile to achieve full coverage, especially with clip levelling systems.
Is Gripset C-Lite suitable for tiling in swimming pools?
Yes. Gripset C-Lite is classified C2TES2 and maintains ≥1 MPa adhesion after water immersion. Allow a 7-day cure before filling the pool to ensure optimal bond strength.
Can I use Gripset C-Lite over existing tiles?
Yes, provided the existing tiles are well bonded. Mechanically abrade at least 80% of the glaze or prime with Gripset OP Primer before applying the adhesive.
What is the open time for Gripset C-Lite?
The adhesive has an open time of approximately 30 minutes at 23°C and 50% RH. Apply tiles within this timeframe to avoid reduced adhesion from surface skinning.
Applications & Benefits
| Application / Use Case | Key Benefit | Primary Trades |
|---|---|---|
| Internal & external wall and floor tiling | Non-slump, high-flexibility formula ensures precise alignment and strong bonds | Tilers, Builders |
| Wet area tiling (bathrooms, laundries) | C2TES2 classification ensures water resistance and adhesion in humid conditions | Tilers, Waterproofers |
| Immersed applications (pools, spas, water features) | ≥1 MPa adhesion after water immersion for long-term submerged durability | Tilers, Waterproofers |
| Large-format tile installation | Non-slump performance prevents lipping; extended open time allows precise positioning | Tilers |
| Underfloor heating systems | High flexibility accommodates thermal expansion and contraction | Tilers, Builders |
| Tiling over Gripset waterproofing membranes | Excellent compatibility ensures full system performance and warranty compliance | Tilers, Waterproofers |
Applying Gripset C-Lite: Enhanced Protocols & Best Practices
-
Surface Preparation
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).
Porous Surfaces
Prime with Gripset GP Primer at 1 L per 8–10 m².
Non-Porous Surfaces
Prime with Gripset OP Primer at 1 L per 12 m².
Timing: Allow primers to dry fully before adhesive application.Pro Tip: For dense concrete or glazed tiles, mechanically abrade surface before priming to enhance adhesion. -
Mixing
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.
Standard Method
Mix for 2–3 minutes, allow to stand for 3 minutes, then re-stir before use.
Batch Mixing
For smaller areas, proportion mix ratio accurately to maintain performance consistency.
Timing: Pot life is approximately 2 hours at 23°C and 50% RH.Pro Tip: Never add more water once the mix has begun to set; this will weaken adhesive performance. -
Application
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.
Standard Tiling
Spread no more than 1 m² at a time to prevent premature skinning.
Clip Levelling Systems
Use 12–20 mm notch trowels and ensure adhesive coverage meets AS 3958 standards.
Timing: Open time ~30 minutes; adjustment time ~40 minutes.Pro Tip: Press tiles into the wet adhesive using a sliding action to eliminate voids. -
Grouting
Allow adhesive to cure for 24 hours before grouting. Ensure all adhesive residue is removed from joints before grout application.
Standard Cure
Grout only when tiles are firmly set and will not be displaced.
Wet Area Precautions
Protect from rain for 24 hours after grouting; allow 3–4 days before wet area service and 7 days before immersion.
Timing: Times may extend in cool or humid conditions.Pro Tip: Use a grout suited to the service environment for maximum durability.
Limitations & Safety
Product Limitations
Do not apply when surface or ambient temperatures are below 5°C or above 35°C, as this can impair curing and adhesion.
Not recommended for direct fixing onto timber floors; use suitable underlay or sheeting systems.
Not suitable for moisture-sensitive stone; always confirm stone compatibility prior to installation.
Safety & Handling Requirements
Personal Protective Equipment
Wear chemical-resistant gloves (e.g., nitrile), safety glasses, and protective clothing to prevent skin and eye contact. Use knee pads when tiling floors to prevent long-term strain injuries.
Ventilation Requirements
Use in well-ventilated areas. When working indoors, maintain airflow with fans or open windows to minimise dust accumulation during mixing.
Fire & Handling Precautions
Gripset C-Lite is non-flammable. Store in a cool, dry location away from direct sunlight and sources of moisture. Keep packaging sealed until ready for use.
Emergency First Aid
Eyes:
Rinse immediately with plenty of clean water for at least 15 minutes. Seek medical attention if irritation persists.
Skin:
Wash thoroughly with soap and water. Remove contaminated clothing.
Inhaled:
Move to fresh air. Seek medical advice if symptoms occur.
Swallowed:
Rinse mouth with water. DO NOT induce vomiting. Seek immediate medical attention.
Seek medical attention immediately in all cases of serious exposure.
