Gripset 11Y: A Technical Overview
Gripset 11Y is a concentrated SBR latex polymer admixture engineered to upgrade the performance of cement-based systems in demanding Australian site conditions. By modifying cement chemistry, it increases adhesion to a wide range of substrates, reduces permeability, and improves flexural strength, making it ideal for waterproofing, structural repair, and high-bond primer applications. Its low water/cement ratio and ability to resist aggressive environments — including freeze/thaw cycles, de-icing salts, and efflorescence — ensure long-term performance in submerged, subterranean, and exposed projects. Whether used in renders, screeds, patch mortars, or as an adhesive/grout enhancer, Gripset 11Y delivers reliable, consistent results that meet professional expectations.

Frequently Asked Questions
Can Gripset 11Y be used in fully submerged applications?
Yes. Gripset 11Y delivers high water resistance and is suitable for use in swimming pools, water tanks, and other immersed areas. Always ensure the substrate is primed with the 11Y slurry and follow a wet-on-wet application for maximum adhesion.
What is the correct slurry primer mix ratio for Gripset 11Y?
The standard slurry primer is mixed in equal parts by volume: 1 part Gripset 11Y, 1 part sharp wash sand, and 1 part cement. Mix to a fluid consistency and apply at approximately 1.0 mm thickness.
Can Gripset 11Y improve the performance of tile adhesives and grouts?
Yes. By replacing a portion of mix water with Gripset 11Y (1:3 ratio with water), you can significantly increase adhesion, reduce permeability, and enhance durability in adhesives and grouts exposed to challenging environments.
Is Gripset 11Y compatible with asphalt or bitumen substrates?
Yes, provided the asphalt or cured bitumen surface is clean, sound, and free from contaminants. Surface preparation is critical to ensure optimum bond strength.
What is the shelf life of Gripset 11Y?
Gripset 11Y has a 12-month shelf life when stored in unopened containers at room temperature, away from direct sunlight, freezing conditions, and off concrete floors.

Applying Gripset 11Y: Enhanced Protocols & Best Practices
-
Surface Preparation
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.
Mechanical Preparation
Use grinding or abrasive blasting to remove laitance and contaminants, achieving an open surface for maximum adhesion.
Cleaning & Damping
Vacuum or blow off dust, then lightly dampen porous surfaces immediately before priming to control suction.
Timing: Complete preparation immediately before slurry priming to prevent recontamination.Pro Tip: Check for hidden contaminants like oil or wax using a water-drop test – if water beads, clean again before priming. -
Mixing Gripset 11Y Slurry Primer
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.
Standard Ratio
1 part Gripset 11Y : 1 part sharp washed sand : 1 part cement. Mix slowly with a paddle mixer to a fluid slurry consistency.
Pre-Use Rest
Allow mix to stand for 3–4 minutes, then lightly re-stir before application to ensure even dispersion.
Timing: Apply slurry immediately after remixing to avoid settling.Pro Tip: For very porous substrates, lightly pre-dampen before priming to prevent rapid moisture loss. -
Preparing 11Y-Modified Screeds, Renders & Mortars
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.
Screeds/Renders
Dry mix 1 part cement : 4 parts fine washed sand. Liquid mix 1 part 11Y : 3 parts water. Combine to a workable consistency.
Patch Mortars
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.
Timing: Apply mortar/screed wet-on-wet over freshly applied slurry primer.Pro Tip: Always prime before placing the mix to maximise adhesion and durability. -
Using as Adhesive & Grout Enhancer
Replace part of the adhesive or grout mix water with a Gripset 11Y and water solution to improve bond strength and moisture resistance.
Mix Ratio
1 part Gripset 11Y : 3 parts water. Use as total mix liquid with cement-based adhesives or grouts in high-performance applications.
Special Conditions
Ideal for immersed, external, or high-traffic areas where standard mixes may degrade faster.
Timing: Mix only enough for immediate use – pot life will vary with ambient temperature.Pro Tip: Avoid over-watering; maintaining the correct polymer ratio is key to achieving performance gains. -
Clean-Up
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.
Wet Cleaning
Rinse with clean water while product is still wet.
Dry Removal
Mechanically remove dried residues; avoid using solvents that may damage equipment.
Timing: Clean before product begins to set to save time and prevent tool damage.Pro Tip: Keep a bucket of clean water nearby for immediate tool rinsing during application.
Limitations & Safety
Product Limitations
Not suitable for direct application onto glass or glazed ceramic surfaces without approved treatment.
Do not use over raw or unprotected steel or metals unless specified in a compatible system.
Not to be used for priming areas with rising moisture or negative hydrostatic pressure — treat first with Gripset E60.
Ensure sand used for bonding agent mixes is a sharp washed grade and cement is fresh Portland cement.
Safety & Handling Requirements
Personal Protective Equipment
Wear chemical-resistant gloves, safety glasses or goggles, and protective clothing to prevent skin contact. Use safety footwear when working on wet or uneven surfaces.
Ventilation Requirements
Ensure adequate ventilation in enclosed areas during mixing and application to prevent inhalation of dust from cementitious components.
Fire & Handling Precautions
Gripset 11Y is non-flammable. Avoid contact with strong oxidising agents. Store in original sealed containers at room temperature, away from direct sunlight and freezing conditions.
Emergency First Aid
Eyes:

Skin:
Wash thoroughly with soap and water. Remove contaminated clothing and launder before reuse.
Inhaled:
Move to fresh air. Seek medical attention if symptoms develop.
Swallowed:
Rinse mouth with water. Do not induce vomiting. Seek immediate medical assistance.
Seek medical attention immediately in all cases of serious exposure.
Gripset 11Y Application Guide
Concrete (new or existing)
Surface Preparation
Substrate must be clean, sound, dry and free of laitance, dust, oils, curing compounds and other contaminants. Mechanically prepare (grind or abrasive blast) to expose a solid, open surface.
