PowerChem Pink SBR Bonding Agent is designed for professional plasterers and contractors needing a durable, moisture-resistant bonding solution for renders, floor screeds, and concrete repairs. Its key benefit is the high-visibility pink tint that acts as a visual guide to ensure complete surface coverage, preventing missed spots or uneven priming. While it offers superior performance in damp environments compared to traditional PVA, users should note that its high-tack formula requires careful application to avoid excessive pooling, as the product dries into a tough, resilient film.

Yes, unlike PVA, this SBR formula is designed to be moisture-resistant and is suitable for external renders.
The pink tint is intended to guide coverage. While it is stable, very thin or translucent topcoats may require a white primer layer over the SBR.
Typically 15-30 minutes, though this varies based on ambient temperature and the porosity of the substrate.
Yes, refer to the technical data sheet for specific dilution ratios depending on whether you are using it as a primer or a mortar additive.
Wash with warm soapy water immediately before the product cures, as it becomes permanent once dried.
Use a brush to redistribute excess material while wet; do not allow it to dry as a thick puddle, as this can affect adhesion.
High humidity or low temperatures can slow the curing process. Ensure adequate ventilation to allow moisture to escape.
Ensure the substrate is not overly porous; pre-dampen extremely dry, thirsty concrete before applying the primer.
Ensure that all surfaces are structurally sound, clean, and free from dust, oil, or loose debris before application. For priming, apply the SBR evenly using a roller or brush, avoiding heavy pooling in corners. If using as an additive in a mix, follow the specific dilution ratios recommended for the mortar application type.
Regarding care, keep containers tightly sealed when not in use and store in a frost-free environment. Tools should be cleaned immediately with water while the product is still wet; once cured, the agent is highly resistant to water and will require mechanical removal.
