Fosroc Nitobond SBR Latex | Polymer Liquid for Improved Screed and Plaster

Overview

Fosroc Nitobond SBR is a styrene-butadiene rubber (SBR) latex-based bonding and admixture liquid used to improve adhesion between old and new concrete, and to strengthen screeds, renders, and plasters. Mixed with cement slurry or mortar, it reduces shrinkage cracking and improves water resistance in repair and finishing work.

Key Specifications

• Type: SBR latex polymer liquid
• Use: Bonding coat for old-to-new concrete joints; admixture for screeds, renders, and plaster
• Benefits: Improved adhesion, reduced shrinkage cracking, better water resistance
• Available packs: 5 Ltrs (small repair jobs) and 20 Ltrs (larger screed/plaster batches)

Available Sizes

• 5 Ltrs — suited to small patch repairs, balcony/bathroom screeds, and touch-up plastering.
• 20 Ltrs — suited to larger floor screeding, full-room plastering, and bigger bonding-coat jobs where fewer top-ups are convenient.

How to Use

1. As a bonding coat: dilute with water per the datasheet ratio and brush onto the clean, dampened old concrete surface; apply fresh mortar while the bonding coat is still tacky.
2. As an admixture: add the diluted liquid to the gauging water for screed, render, or plaster mixes instead of plain water.
3. Cure normally after application, keeping the surface protected from rapid drying for the first 24 hours.

Frequently Asked Questions

Can I use Nitobond SBR for waterproofing plaster?
Yes, it's commonly added to plaster/render mixes to improve water resistance and reduce cracking.

Which size should I buy for a bathroom screed?
The 5 Ltrs pack is usually enough for a single bathroom or balcony screed; pick the 20 Ltrs pack for whole-floor or multi-room work.
