At a Glance: Key Applications

Use Plastabond for: Improving adhesion and workability of cement-based mortars, renders, screeds, and repair slurries. Ideal for floor preparation, patch repairs, and surface priming.

Plastabond: A Technical Overview

Plastabond is a PVA-based bonding agent and plasticizer designed to enhance mortar performance across a wide range of construction applications. By increasing mechanical strength, adhesion, and elasticity, Plastabond ensures your patch mortars, renders, and floor screeds bond securely while resisting shrinkage, water ingress, and abrasion. The water-dispersed polyvinyl acetate formulation delivers strong cohesive strength and excellent compatibility with cementitious mixes—crucial for long-term durability in both internal and external conditions.

Core Features & Specifications

  • Polyvinyl acetate formulation with high bond strength
  • Improves elasticity and mechanical performance of mortar
  • Non-corrosive to reinforcing steel
  • Reduces shrinkage, cracking, and water permeability
  • Non-flammable and solvent-free
  • Cures to a clear finish with low odour

The Plastabond Advantage

  • Strengthens bond between new and old concrete for durable overlays
  • Enhances patch repair mortars for long-term adhesion and flex
  • Improves water resistance and chemical tolerance in screeds
  • Ideal for internal and external use in Australian climate zones

Coverage Rate & Yield

As a bonding agent, dilute Plastabond 4:1 with water and apply at approximately 8 m² per litre. For use as a plasticizer admixture, dilution ratios range from 1:10 to 1:1 depending on strength and flexibility requirements. Approximately 7–10 litres of mixed solution is typical per bag of cement.

Required Tools & Equipment

  • Concrete mixer or mixing bucket
  • Brush or roller (for bonding coat)
  • Trowel or float (for screeds and renders)

Pro Tips for Best Results

  • Always apply bonding coat while tacky, not dry
  • Ensure consistent mixing for uniform performance
  • Protect early-age mortars from water ingress or drying winds

Avoiding Common Issues

  • Do not apply over dusty or contaminated substrates
  • Incorrect dilution can affect adhesion or strength
  • Avoid application outside the 5–35°C range

Storage & Shelf Life Considerations

Store Plastabond in a cool, dry place between 10°C and 35°C. Avoid frost. Shelf life is 12 months in unopened original packaging.
