Elevate the performance of cement-based projects to withstand the toughest conditions. Gripset 11Y acts as a concentrated SBR latex polymer, transforming standard screeds, renders, and mortars into high-performance compounds. It delivers enhanced adhesion, boosts strength, and significantly increases water resistance, ensuring durability in demanding environments like continuous immersion and external exposure.
Cement-based compounds are foundational, but often require enhanced performance to resist the long-term impact of water, movement, and aggressive conditions. Gripset 11Y was formulated as a concentrated SBR latex polymer, designed to act both as an admixture and a high-bonding primer. It significantly improves the inherent properties of screeds, renders, mortars, adhesives, and grouts, preventing issues like poor adhesion, delamination, and efflorescence that compromise structural integrity and aesthetic finish.
It owns the job of enhancing adhesion, flexural strength, and water resistance, critical for applications exposed to weather, continuous immersion, freeze/thaw cycles, and subterranean environments. Gripset 11Y ensures that cementitious systems maintain their integrity and performance, even when unmodified mixes would fail.
Gripset 11Y delivers measurable performance improvements without relying solely on numerical specifications. Its concentrated SBR latex formulation means:
Gripset 11Y is a thin, white liquid, simplifying integration into cementitious mixes. Its versatility allows for various mix designs:
Clean tools with water immediately while wet to prevent dried product from adhering, which would require mechanical removal.
Gripset 11Y is repeatedly specified in critical areas where long-term performance under stress is essential:
Gripset 11Y consistently appears as a foundational first step in high-performance waterproofing and flooring systems. For wet areas like bathrooms and laundries, or external applications like balconies, it's typically the initial layer: a Gripset 11Y slurry primer is applied before the main waterproofing membrane and subsequent floor finishes. This early application establishes a critical high-bond interface, ensuring optimal adhesion for the entire build-up.
In swimming pool systems, the Gripset 11Y Slurry Primer often precedes the application of other Gripset components like Elastoproof collars and Gripset C-Lite, forming a robust, water-resistant foundation for tiled pools and water features. Its role as a primer ensures the subsequent waterproofing layers bond effectively to the prepared concrete or masonry.
Unlike standard admixtures or general-purpose primers, Gripset 11Y is a concentrated SBR latex polymer specifically formulated to enhance adhesion, flexural strength, durability, and water resistance of cement-based compounds. It excels in demanding environments where unmodified mixes or basic primers would underperform, providing a targeted performance upgrade rather than a general enhancement.
Yes, Gripset 11Y is specifically formulated for continuous immersion and subterranean environments. It enhances the waterproof properties and durability of cement-based compounds in these demanding conditions.
Do not use Gripset 11Y on glass or glazed surfaces. It is also not suitable for raw steel or metals unless specifically instructed, nor for areas with active rising moisture or negative hydrostatic pressure.
It is an SBR latex polymer that significantly improves adhesion strength, flexural strength, and water resistance. It also reduces permeability, efflorescence, and shrinkage, making mixes more durable in harsh conditions, including freeze/thaw cycles.
Mix 1 part Gripset 11Y, 1 part wash sand, and 1 part fresh Portland cement by volume. Use an electric mixer to form a fluid slurry, then let it settle for 3-4 minutes before a final stir to ensure solids are suspended.
| Application | Key benefit | Primary trades |
|---|---|---|
| High bonding primer/sealing slurry | Ensures superior adhesion for cementitious overlays, particularly in immersed or subterranean areas. | Waterproofers, Concreters, Tilers |
| Water-resistant screeds and renders | Increases flexural strength, reduces efflorescence, and enhances water resistance, preventing premature failure in wet environments. | Renderers, Plasterers, Concreters |
| Patch mortars and thin build coatings | Provides water resistance and durability for repairs in areas subject to continuous moisture or immersion. | Masons, Concreters, Repair Specialists |
| Cement-based adhesive and grout enhancer | Improves water resistance and bond of tile adhesives and grouts, suitable for challenging and harsh climatic conditions. | Tilers, Waterproofers |
Ensure all substrates are clean, sound, dry, and free from dust, oil, grease, curing agents, moss, algae, or other contaminants. Mechanically remove weak or loose material. Treat active moisture or rising damp with Gripset E60 before application.
Use grinding or abrasive blasting to remove laitance and contaminants, achieving an open surface for maximum adhesion.
Vacuum or blow off dust, then lightly dampen porous surfaces immediately before priming to control suction.
Create a high-bond slurry primer for screeds, renders, or patch mortars by combining equal volumes of Gripset 11Y, sharp washed sand, and fresh Portland cement.
1 part Gripset 11Y : 1 part sharp washed sand : 1 part cement. Mix slowly with a paddle mixer to a fluid slurry consistency.
Allow mix to stand for 3–4 minutes, then lightly re-stir before application to ensure even dispersion.
Form a mixing liquid by combining Gripset 11Y with water at the required ratio, then blend with dry cement/sand mixtures to achieve the desired consistency.
Dry mix 1 part cement : 4 parts fine washed sand. Liquid mix 1 part 11Y : 3 parts water. Combine to a workable consistency.
Dry mix 1 part cement : 3 parts fine washed sand. Liquid mix 1 part 11Y : 1 part water. Minimum build 3 mm for thin coatings.
Replace part of the adhesive or grout mix water with a Gripset 11Y and water solution to improve bond strength and moisture resistance.
1 part Gripset 11Y : 3 parts water. Use as total mix liquid with cement-based adhesives or grouts in high-performance applications.
Ideal for immersed, external, or high-traffic areas where standard mixes may degrade faster.
Clean all tools and mixing equipment with water immediately after use. Do not allow mixed material to dry on tools – hardened product must be removed mechanically.
Rinse with clean water while product is still wet.
Mechanically remove dried residues; avoid using solvents that may damage equipment.
Gripset 11Y is not classified as hazardous by Safe Work Australia.
When handling for general use, wear safety shoes, overalls, gloves, and safety glasses. Nitrile rubber gloves are suggested for intermittent contact.
Ensure a well-ventilated area for handling and mixing.
Store in a cool, dry, well-ventilated place, out of direct sunlight. Keep containers closed and check for leaks. Avoid freezing conditions and storage directly on concrete floors. Shelf life is 12 months in unopened containers. Clean tools with water while wet; dried product requires mechanical removal.
Proper surface preparation is crucial for Gripset 11Y to achieve its full bonding and enhancing capabilities. Poor prep leads to adhesion failure.
Surface prep: All surfaces must be clean, sound, dry, and free from loose material, dust, oil, grease, and curing compounds. Mechanically remove unsound layers by grinding or abrasive blasting to ensure a robust surface.
Primer: Required. Use the 11Y primer/sealing slurry. Very porous surfaces can be lightly dampened before slurry application.
Surface prep: Ensure surfaces are clean, free of dust and loose particles. Remove any contaminants that could compromise adhesion.
