AQUA BOND
Synthetic-rubber latex admixture for improving the adhesion and performance of cement-based mortars, screeds, renders and bonding slurries
Description
AQUA BOND is a synthetic-rubber latex admixture for improving the adhesion and performance of cement-based mortars, screeds, renders and bonding slurries. The reference product is a stable water dispersion of an SBR (styrene-butadiene rubber) synthetic elastomer with a low glass transition temperature. The elastomer provides elasticity and ageing stability. When added to cement and aggregate mixes it improves adhesion, plasticity, thixotropy, water retention and workability.
Where to Use
AQUA BOND is designed for improving the mechanical and adhesive characteristics of cement-based screeds, renders, thin smoothing layers, and highly adhesive bonding slurries. Suitable for interior and exterior applications, including industrial floors, repair mortars, ramps, channels, and high-abrasion surfaces.

Directions for Use
Substrate Preparation
Substrate must be solid, compact and clean. Remove loose material, dust, concrete crusts, oil, form-release agents and paint by suitable cleaning methods. Thoroughly wet the substrate, leaving no excess water.
Mixing
Dilute Aqua Bond with water according to the selected application ratio. Add the solution to the mixer, then add cement and aggregates. Mix for 2–3 minutes until smooth and even; do not over-mix. Setting time is not significantly different from normal mixes; workability is usually slightly longer.
Curing
In warm or windy conditions, cure carefully to prevent rapid evaporation and plastic-shrinkage cracking. Protect or damp-cure the surface during the first hours.
Cleaning
Clean tools with water before setting begins. After hardening, mechanical cleaning is required.
Recommendations & Workability Guidelines
This is a branded Aqua Bond draft based on the technical information contained in the uploaded Planicrete reference data sheet. The mixing ratios, physical values and performance figures above are reference values from that source and have not been independently validated as specifications for your Aqua Bond production. Before commercial release, replace or confirm the values with your own laboratory QC and production data, including density, solids, pH, viscosity, shelf life, packaging, coverage, test results and applicable regulatory information. The source document itself states that its technical details and recommendations are indicative and should be confirmed through practical application. Product suitability and final responsibility remain with the user.
