Mastic Gun 11in Heavy Duty Steel for Silicone & Sealant

A heavy duty mastic gun for applying sealant and silicone from standard cartridges in a controlled, straightforward way. Built with an 11in body, steel frame and plunger, plus a cast aluminium handle, it suits regular sealing work around the home, garage or workshop.

Used for sealing gaps, joints and edges during home maintenance, DIY repairs and general fitting work, this type of caulking gun is handy when working with silicone around kitchens, bathrooms, windows, doors and trim. It also suits garage and workshop jobs where sealant needs to be applied neatly during vehicle maintenance, light servicing or general repair work. For anyone using cartridges on a fairly regular basis, a solid manual gun gives better control than trying to manage awkward squeezing by hand.

The 275mm frame size is made to take most standard sealant cartridges, making it a practical choice for common sealing jobs without needing anything specialised. The steel frame and plunger give the tool a sturdy feel in use, while the cast aluminium handle provides a robust hand grip for repeated application work. That combination is useful when moving steadily along longer joints or when applying thicker material with consistent pressure. For regular maintenance and repair jobs, it helps keep sealant application more controlled and less fiddly.
