When it comes to strong, long-lasting fixings, standard mechanical anchors don’t always cut it. That’s where Chemical Anchor Resins come in—a powerful solution for securing fixings into brick, concrete, stone, and masonry. Whether you’re a professional joiner, builder, or DIY enthusiast, choosing the right chemical anchor resin is essential for durability and performance.

At Next Day Fixings, we offer a complete range of chemical anchor resins for nationwide next-day delivery. Place your order before 3 PM, Monday to Friday, and we’ll dispatch it the same day for next-working-day delivery.

This guide will walk you through everything you need to know about chemical anchor resins, including types, applications, pros and cons, and how to use them effectively.

Chemical Anchor Resin is a high-strength bonding agent used to secure studs, threaded bars, and other fixings into masonry or concrete. Instead of relying on expansion like mechanical anchors, it bonds directly with the substrate, creating an exceptionally strong and durable hold.

🔹 Ideal for high-load applications
🔹 Works in both solid and hollow materials
🔹 Reduces stress on the surrounding material

Common uses include:

✔️ Fixing structural elements into brick, stone, or concrete
✔️ Securing bolts for steelwork, timber, or heavy machinery
✔️ Anchoring handrails, fences, and balustrades

There are three main types of chemical anchor resins available at Next Day Fixings:

1. Polyester Resin – Cost-effective for non-critical applications
2. Polyester Styrene-Free Resin – Low-odour, ideal for enclosed spaces
3. Vinylester Styrene-Free Resin – High-performance, suitable for damp/wet environments

Each type has unique strengths and ideal uses, which we’ll cover in detail below.

✅ Best for: General-purpose applications in hollow & solid masonry
✅ Available Sizes: 300ml & 410ml

Polyester Resin is one of the most commonly used chemical anchor resins due to its affordability, ease of use, and versatility. It is a two-component system, where the resin and hardener mix inside a nozzle during application, ensuring a consistent, even blend for secure fixings.

This resin is ideal for non-safety-critical applications, where extreme strength and load-bearing capacity are not primary concerns. It works well in both solid and hollow masonry, making it a go-to choice for general construction, DIY projects, and everyday fixings.

✔ Budget-friendly & easy to apply – A cost-effective solution for standard anchoring needs.

✔ Fire-rated & CE approved – Meets European safety standards.

✔ Low extrusion force – Easier to dispense, reducing hand fatigue when applying.

✔ Quick curing time – Speeds up installation without compromising strength.

✔ Mixing nozzle included – Ensures the perfect resin-to-hardener ratio every time.

✔ Suitable for close edge fixing – Can be used near edges without cracking masonry.

👉 Timber Fixings – Perfect for securing timber beams, decking posts, and fencing stakes into concrete or brick.
👉 Handrails & Balustrades – Provides a solid hold for stainless steel or metal handrails.
👉 Signposts & Bollards – Commonly used in landscaping and public spaces.
👉 Brackets & Frames – Suitable for light to medium-duty structural fixings.
👉 Cable Tray & Conduit Fixings – Frequently used in electrical installations.

⚠️ Limitations of Polyester Resin:
❌ Not recommended for heavy load-bearing applications or safety-critical installations.
❌ Should only be used in well-ventilated areas due to its styrene-based composition.
❌ Not suitable for damp or wet conditions, as it may not bond effectively.

💡 Next Day Fixings Polyester Resin Options:
📦 300ml (PE310) – Fits a standard silicone gun, making it ideal for smaller jobs.
📦 410ml (PE410) – Requires a special applicator gun but provides greater coverage for larger projects.

✅ Best for: Indoor applications or poorly ventilated areas
✅ Available Size: 300ml

If you need a polyester-based resin without the strong odour, Polyester Styrene-Free Resin is the best alternative. This low-odour resin provides the same anchoring performance as standard Polyester Resin but is formulated without styrene, making it safer and more comfortable to use in enclosed areas like garages, basements, and interior walls.

✔ Low-odour formula – Reduces harmful fumes, making it safer for indoor work.

✔ Ready-to-use & easy to apply – Comes with a mixing nozzle for effortless installation.

✔ Fire-rated & European Approved (ETA Certified) – Complies with safety and quality regulations.

✔ Low extrusion force – Allows for smooth application with less effort.

✔ Minimal wastage – The efficient mixing system ensures all resin is used without excess leakage.

👉 Indoor Stud Fixings – Securely bonds studs, bolts, and anchors inside buildings.
👉 Wall Ties & Masonry Fixings – Perfect for repairing cavity walls or reinforcing weak masonry.
👉 HVAC & Electrical Installations – Commonly used for mounting air conditioning units and heavy electrical boxes.
👉 Light to Medium Duty Structural Fixings – Reliable for securing staircases, shelving, and railings indoors.

⚠️ Limitations of Polyester Styrene-Free Resin:
❌ Not suitable for wet or damp environments, as it requires dry conditions to cure properly.
❌ Less strength compared to Vinylester Resin, so not ideal for heavy-duty fixings.
❌ Only available in 300ml cartridges, making it less cost-effective for large-scale applications.

💡 Next Day Fixings Polyester Styrene-Free Resin Option:
📦 300ml (PESF310) – Compatible with standard skeleton guns for easy application.

✅ Best for: High-load applications in wet, damp, or underwater environments
✅ Available Sizes: 300ml & 410ml

For maximum strength and versatility, Vinylester Styrene-Free Resin is the ultimate solution. Unlike polyester-based resins, Vinylester Resin provides superior tensile strength, resistance to moisture, and excellent durability.

It is particularly well-suited for safety-critical fixings, including structural steelwork, rebar anchoring, and underwater applications. It offers faster curing times, higher chemical resistance, and the ability to bond effectively in damp and wet conditions.

✔ High-performance tensile strength – Stronger than polyester resins.

✔ Works in wet, damp & underwater conditions – Ideal for outdoor and marine applications.

✔ Fire-rated, CE, and WRAS approved – Suitable for rebar, bridges, and high-load structures.

✔ Rapid curing time – Allows for faster installation and load-bearing.

✔ Excellent chemical resistance – Stands up to corrosive environments.

✔ Compatible with all masonry types – Works on solid brick, concrete, stone, and porous surfaces.

👉 Rebar & Structural Fixings – Ideal for reinforcing concrete beams and heavy-load installations.
👉 Marine & Underwater Installations – Suitable for fixings in docks, piers, and wet environments.
👉 Outdoor High-Load Fixings – Perfect for high-strength steel fixings, fences, and heavy-duty anchoring.
👉 Bridge & Infrastructure Projects – Used in civil engineering projects requiring extreme durability.
👉 Heavy-Duty DIY & Landscaping Projects – Great for fixing pergolas, retaining walls, and stone structures.

⚠️ Limitations of Vinylester Styrene-Free Resin:
❌ Slightly more expensive than polyester-based resins due to their high strength and versatility.
❌ Requires special applicator guns for 410ml cartridges.
❌ May cure too fast in high temperatures, requiring careful application in warm conditions.

💡 Next Day Fixings Vinylester Styrene-Free Resin Options:
📦 300ml (VESF300) – Standard size for smaller projects, fits a silicone gun.
📦 410ml (VESF410) – Larger size for bigger jobs, requires a special applicator gun.

Choosing the right chemical anchor resin depends on the application, environment, and load requirements.

• If you need an affordable solution for light-duty masonry fixings, go for Polyester Resin.
• If working indoors with poor ventilation, use Polyester Styrene-Free Resin.
• If you need high strength, moisture resistance, and durability, Vinylester Styrene-Free Resin is the best choice.
