Albion Buyer's Guide — TradieCart
This guide helps you choose the right Albion caulking or sealant gun for your job. Albion Engineering has been building professional dispensing tools since 1929 — their guns are built to last and designed for daily trade use.
Product Range
| Product | Best For |
|---|---|
| B12 300ml 12:1 Cartridge Gun | The go-to cartridge gun for most tradies — 12:1 drive ratio handles silicones, acrylics, and standard sealants with smooth, consistent pressure. Our most popular Albion product. |
| B12S20 600ml 12:1 Sausage Gun | The standard sausage gun for 600ml packs — ideal for silicone, acrylic, and polyurethane sealants. Double gripping plate and rotating barrel for easy use. Our most popular sausage gun. |
| B18 300ml 18:1 Cartridge Gun | Mid-range thrust for thicker sealants — a step up from the B12 when 12:1 isn't quite enough, without jumping to 26:1. |
| B26 300ml 26:1 Cartridge Gun | Highest-thrust manual cartridge gun — for thick polyurethane, fire-rated sealants, or cold weather when materials stiffen up. |
| R6B 300ml Cartridge Gun | Light-duty economy option — 6:1 ratio suits occasional use or thin, easy-flow sealants. |
| B18S20 600ml 18:1 Sausage Gun | Mid-range sausage gun — more thrust than the B12S20 for thicker 600ml sausage packs. |
| B26S20 600ml 26:1 Sausage Gun | Highest-thrust sausage gun — for demanding 600ml materials like polyurethane and fire-rated sealants in cold conditions. |
| E12 12V Cordless 300ml Cartridge Gun | Battery-powered for high-volume work — 180kg force, variable speed trigger, up to 40 cartridges per charge. Saves fatigue on big commercial jobs. |
| B26T600 Multi-Component Cartridge Gun | Two-part epoxy and adhesive dispensing — converts between 1:1 and 2:1 mix ratios. For chemical anchoring, structural adhesives, and two-part sealants. |
| Caulk Slicker Squares 4-pack | Clean, professional sealant finishing — flexible squares for smoothing and shaping sealant joints without mess. |
All cartridge guns fit standard 300ml cartridges. Sausage guns fit 600ml sausage packs — the standard format for construction sealants in Australia.
Understanding Drive Ratios
The drive ratio determines how much force the gun applies per trigger squeeze. A higher ratio means more thrust but slower dispensing — less material moves per squeeze, but with greater force. Choose your ratio based on what you're sealing with:
| Ratio | Force | Speed | Best Sealant Types |
|---|---|---|---|
| 6:1 (R6B) | Low | Fast | Thin acrylics, latex caulks, easy-flow gap fillers. Suits occasional or light-duty use. |
| 12:1 (B12, B12S20) | Medium | Moderate | Silicone, acrylic, MS polymer, standard polyurethane — covers 80%+ of everyday sealing jobs. The all-rounder. |
| 18:1 (B18, B18S20) | Medium-High | Moderate | Thicker polyurethanes, heavier MS polymers, construction adhesives, or sealing in cool weather (10–15°C) when materials start to stiffen. |
| 26:1 (B26, B26S20) | Highest | Slowest | Heavy-duty polyurethane, fire-rated sealants, acoustic sealants, cold weather work (below 10°C), and deep or wide joints needing sustained pressure. |
Rule of thumb: Start with 12:1 — it handles most jobs. Only step up to 18:1 or 26:1 if you're fighting the trigger or the material isn't flowing smoothly. Going higher than you need just slows you down without any benefit.
Quick Recommendation Guide
- Standard silicone or acrylic sealing → B12 cartridge gun or B12S20 sausage gun — the 12:1 ratio is smooth and efficient for everyday sealants
- Thick polyurethane, fire-rated sealants, or cold weather work → B26 cartridge or B26S20 sausage — the 26:1 high-thrust ratio pushes through stiff materials with less hand fatigue
- Two-part epoxy or chemical anchoring → B26T600 multi-component gun — handles 1:1 and 2:1 mix ratios in one tool
- High-volume commercial sealing (50+ cartridges a day) → E12 cordless — saves your hands on big jobs with variable speed and auto-reverse
- Occasional or light-duty use → R6B — simple, reliable, and cost-effective for lighter sealants

Common Questions
Which drive ratio do I need — 12:1 or 26:1? — For standard silicones and acrylics, 12:1 is all you need — it's smoother and easier on your hands. Go with 26:1 only if you regularly use thick polyurethane, fire-rated sealants, or work in cold conditions where materials stiffen up.
Should I get a cartridge gun or sausage gun? — It depends on your sealant format. Standard 300ml cartridges use a cartridge gun (B12, B18, B26). If you use 600ml sausage packs (common in Australian construction), you need a sausage gun (B12S20, B26S20).
Is the B12 or B18 better for me? — The B12 (12:1) is the most popular choice and handles most standard sealants. The B18 (18:1) gives you extra thrust for slightly thicker materials without the full force of the B26. If you're unsure, the B12 is the safe pick.
Do I need a cordless gun? — If you're sealing 50+ cartridges a day on commercial sites, the E12 cordless will save your hands and speed up the job. For standard residential work, a manual gun like the B12 is more cost-effective.
What is the B26T600 used for? — It dispenses two-part products like epoxy adhesives, chemical anchors, and structural sealants that come in side-by-side cartridges. It converts between 1:1 and 2:1 mix ratios.
How long do Albion guns last? — Albion guns are built for professional daily use and are fully rebuildable. With basic care and occasional part replacement, they can last for years on site.
