## Overview

Featuring a reinforced metal skeleton frame, it effortlessly handles thick, high-viscosity sealants in standard 310ml and 400ml cartridges.

## Description

From the manufacturer ProDec is the UK's biggest and most widely distributed brand of trade decorating accessories, so whether you're a seasoned pro, enthusiastic DIYer or even a beginner, we've got everything you need for a great finish - just add paint A cut above standard skeleton caulking guns A staple tool in the trade professional's van and DIYer's garage, the skeleton caulking gun is a classic, economical design for applying cartridge-based sealants, caulk and fillers. With VOC (solvent) regulations continuing to tighten, today's sealants are often more viscous than previously, increasing the demands on both the gun to push them through the cartridge and the effort required by the user. This trade quality, extra strength model features reinforcements to key areas for heavier duty performance compared to standard skeleton guns, notably a thicker grade of steel to the skeleton and a more robust trigger. Featuring ergonomic finger moulding for comfort, the powerful trigger drives the plunger to efficiently and evenly push the sealant through the cartridge for maximum efficiency and smooth application, giving reduced user fatigue. A release clip stops the flow when required and gives a clean break in the sealant bead, ensuring no long, messy strings. The reverse end of the steel plunger features a U-shape that's ideal for hooking onto a belt or ladder when working at any kind of height. Powder coated for durability and resistance to rust, the gun is suitable for standard 310ml DIY and 400ml trade cartridges as well as intermediate sizes. Solutions for applying fillers and sealants from ProDec Fillers, sealants and caulk are essential to getting your surface perfectly smooth ready for painting or papering. Whether you're applying or smoothing, filling deep holes, hairline cracks, long joins between plasterboard panels and more, ProDec has a range of tools to help you get your surface in tiptop condition. Rosewood filling knives A flexible stainless steel blade with full tang that extends all the way through the handle and prevents it snapping at the join of handle and blade, giving it a much longer lifetime than half tang and DIY scrapers. Mounted onto a premium quality varnished handle made from durable rosewood. Available in 1", 2", 3" and 4" sizes. Duragrip filling knives A flexible stainless steel blade with full tang mounted onto ProDec's premium quality Duragrip soft grip handle that is ergonomically shaped for reduced hand fatigue. It also has a solid steel hammer end which is useful for quickly and efficiently hammering nails, tacks, wall plugs, etc. Available in 1.25", 2", 3" and 4" sizes. Filling blades A deep, thin and flexible steel blade mounted onto a short, full width plastic handle which gives close control with general purpose and fine surface fillers on walls, ceilings and woodwork. Available in a pack of 4 mixed sizes containing 2", 3", 4" and 5" widths. Caulkers With a flexible plastic blade that has a wider profile than standard filling knives, caulkers enable you to fill gaps of many shapes and sizes quickly and efficiently. They are particularly useful where long joins require sealing, such as marrying plasterboards together. Available in 8", 10" and 12" sizes. Taping knives A high carbon steel blade, heat treated for strength. It has a laser-straight edge that makes it ideal for smoothing plasterboard jointing tape down to give the lowest possible profile for a seamless appearance when plastered, as well as filling seams and holes for an ultra-smooth, professional finish. Available in 6", 8", 10" and 12" sizes. Skeleton caulking guns Trade quality guns for applying cartridge-based sealants, caulk and fillers, featuring a powerful trigger, robust plunger and a release clip to give a clean break in the sealant bead, ensuring no long, messy strings. Available in standard format plus a reinforced model that is especially ideal for higher viscosity sealants. Revolving caulking gun Refines the classic skeleton design to the next level, for trade quality, ultra-smooth application of cartridge-based sealants, caulk and fillers. The reinforced barrel not only gives heavy duty performance, it can be rotated during application to give a continuous smooth bead around corners and in awkward areas. Foil sausage guns Robust, full metal barrel construction ensuring no mess when used with foil-based sealants, caulk and fillers and also compatible with traditional cartridges. Features powerful plunger and powdered coated trigger with quick release clip for precise control to stop the flow when required. Available in 400ml and 600ml versions.

Review: Good caulk is key - Solid bit of kit. Feels sturdier than the usual cheap skeleton guns and has enough leverage to push out thicker sealants without your hand cramping up. The trigger is smooth, the frame doesn’t flex, and it keeps good pressure on the tube so the flow stays steady. Used it on silicone, adhesive and filler and it handled all of them without slipping or bending. For the price, it’s one of the better caulking guns you can throw in the toolbox — simple, reliable, and does exactly what you need it to.
Review: Sturdy, smooth, and built to last - Excellent caulking gun – feels solid and well-balanced in the hand. Easily handles thicker, high-viscosity sealants without jamming or straining. The trigger action is smooth and controlled, making it easy to get a clean line. Fits both 310ml and 400ml cartridges snugly. Ideal for both DIY and professional jobs. Great build quality and very good value for a heavy-duty applicator.
