At a Glance: Key Applications
Use Everbond General Purpose PVA for: Assembly bonding, cabinetmaking, veneering, block joining, and laminating in dry interior conditions
Everbond General Purpose PVA: A Technical Overview
Everbond General Purpose PVA is a synthetic resin adhesive formulated for timber-based substrates in cabinetry, joinery, and shopfitting. It forms a hard, translucent bond line that is non-toxic, non-staining, and resistant to mould and bacteria. Offering easy sandability and rapid handling strength, it’s a go-to choice for interior wood applications. This PVA adhesive performs reliably under normal humidity conditions and allows press times as short as 10 seconds for paper laminates and 60 seconds for high-pressure laminate bonding at elevated temperatures.
Core Features & Specifications
- Forms a hard, translucent bond that’s easily sanded
- Water-based and non-toxic for safer indoor use
- Fast press times: as little as 10–60 seconds in production settings
- Viscosity between 9300–13500 cP for ideal flow and spreadability
- Resistant to mould, bacteria, and fungi
- Compatible with thermo-curing for enhanced water resistance
The Everbond General Purpose PVA Advantage
- Reduces rework with a non-staining formula
- Ideal for high-speed production due to short press times
- Thermo-curing enhances bond strength in moisture-prone assemblies
- Easy water clean-up reduces downtime
Cure Profile & Performance
Initial handling strength is achieved in 10–60 seconds depending on substrate and pressure. Full curing is complete in approx. 7 days under ambient conditions. Cure can be accelerated with heat, or enhanced with 1% catalyst for improved water resistance.
Coverage Rate & Yield
For surface bonding: 80–140 g/m². For assembly bonding: 160–180 g/m². Yield varies by substrate porosity and application method.
Application information cards
Required Tools & Equipment
- Glue roller or brush
- Press or clamp (manual or hydraulic)
- Thermal press (optional for enhanced curing)
Pro Tips for Best Results
- Apply evenly with consistent spread rate
- Ensure substrate moisture content is 8–12%
- Thermo-cure with 1% catalyst for higher bond performance
Avoiding Common Issues
- Avoid using below 8°C application temperature
- Don’t allow adhesive to dry in application equipment
- Press time must suit the substrate and environmental conditions
Storage & Shelf Life Considerations
Store in cool, dry areas between 10°C–30°C. Keep containers sealed when not in use. Shelf life is 6 months from manufacture in original packaging.
Certifications & Regulatory Compliance
Not classified as hazardous under Safe Work Australia. Suitable for indoor use with minimal health risks. Always refer to MSDS before handling.
Frequently Asked Questions About Everbond General Purpose PVA
Q: Can this PVA adhesive be used outdoors?
A: No. Everbond GP is suitable for indoor applications only. It resists normal humidity but is not waterproof. For outdoor or wet area use, a waterproof PVA or polyurethane adhesive is recommended.
Q: How long should I wait before machining the bonded panels?
A: Machining can usually begin once the adhesive has cured for at least 30 minutes for basic handling. However, allow up to 7 days for full cure before subjecting to high stress or humidity.
Q: Can I use this PVA with high-pressure laminates?
A: Yes. When used with short-cycle presses at approx. 70°C, it bonds HPL in as little as 60 seconds, provided substrates are properly aligned and pressure is uniform.
Q: What’s the benefit of using the catalyst with this product?
A: Adding 1% w/w catalyst allows for thermo-curing, which significantly increases water resistance of the final bond. It’s ideal for more demanding internal applications like kitchen cabinetry.

Applying Everbond General Purpose PVA: Protocols & Best Practices
General Application Steps:- Preparation: Ensure surfaces are clean, dry, and free from oil or dust. Light sanding may improve bond strength.
- Application: Apply evenly using brush or roller. Use appropriate pressure via clamps or presses. Maintain substrate temp above 8°C.
- Tooling & Finishing: Wipe off excess with damp cloth. Do not allow adhesive to dry on tools. Clean with water immediately.
- Curing: Full bond strength develops over 7 days. Accelerate cure using heat or catalyst for high-performance applications.
For Joiners: Block Joining for Cabinet Carcasses
The Engineering Challenge: Achieving rapid and uniform bond strength across multiple timber contact points during carcass assembly.
The System-Based Solution with Everbond GP: Short press times and balanced viscosity enable quick setup without slippage, even in horizontal clamps.
Best Practice Note: Use clamps or press pressure of 4–5 kp/cm² for optimal hold; clean off squeeze-out immediately to reduce sanding time later.
