Blue Spot Sealant & Caulking Guns

Blue Spot Sealant & Caulking Guns at Tooled-Up.com

Blue Spot Sealant & Caulking Guns are practical application tools for dispensing silicone, acrylic and polyurethane sealants, plus construction adhesives, from standard cartridges. They are built around simple manual designs, with no batteries, chargers or 240v supply needed. That makes them easy to keep in the van, toolbag or kitchen drawer.

Browse the Blue Spot selection at Tooled-Up.com and you will find manual skeleton frame guns for everyday sealing and heavier-duty frames for thicker materials. Expanding foam guns sit alongside them for gap-filling and insulation work. Each type is designed to give controlled, repeatable application without fuss.

Key Features of Blue Spot Sealant & Caulking Guns

• Steel frame construction: a sturdy frame stands up to knocks on site and in the workshop while keeping the gun light enough for all-day use.
• Smooth plunger action: consistent pressure on the cartridge helps produce an even bead, so there is less wasted sealant and less tidying up afterwards.
• Pressure release: on models with this feature, the flow stops when you let go of the trigger. This helps prevent drips and gives cleaner joint lines around baths, windows and frames.
• Standard cartridge fit: the guns are designed for common 310ml cartridges, so you can choose your sealant or adhesive based on the job rather than the gun.
• Skeleton frame design: an open frame lets you see how much product is left and makes cartridge changes quicker.
• Comfortable trigger and grip: good leverage reduces hand strain on longer runs of sealant.

Popular Blue Spot Sealant & Caulking Guns

Manual skeleton frame guns

The lightweight, general-purpose choice. They suit silicone, acrylic and decorative caulking work, and the open frame makes them easy to load and monitor.

Heavy-duty manual guns

A stronger frame and better mechanical advantage help when you are pushing thicker, more viscous products such as construction adhesives. They are a sensible pick for tradespeople who regularly use demanding materials.

Compact and budget-friendly guns

Ideal for occasional use, or as a spare for the van or a second crew member. They cover the basics without extra cost.

Expanding foam guns

The Expanding Foam Guns sub-category covers tools for applying expanding foam to fill gaps, seal around pipework and insulate. Shop Blue Spot Sealant & Caulking Guns at Tooled-Up.com to pick the right applicator for the cartridge or foam you are using.

Frequently Asked Questions

What cartridge size do Blue Spot caulking guns take?

They are designed for standard 310ml cartridges, the most common size for sealants and adhesives in the UK. Always check the cartridge size before buying, particularly for specialist products.

Which Blue Spot gun is best for thick adhesives?

Choose a heavy-duty manual model. Its stronger frame and improved leverage make it easier to push viscous construction adhesives than a lightweight skeleton gun.

How do I stop sealant running on after I release the trigger?

If your gun has a pressure release, use it straight after finishing the bead, either by pulling back the plunger rod slightly or by operating the release catch. This relieves pressure on the cartridge and reduces dripping.

Can I use a sealant gun for expanding foam?

No. Standard caulking guns are made for cartridges, while expanding foam needs a dedicated foam gun. Check the Expanding Foam Guns category for the correct applicator, and follow the manufacturer's guidance and COSHH advice when using any chemical product.
