310ml sealant gun for construction work.

Features

• Type: Mechanical sealant gun (mainly, as it is the most popular type for 310ml).
• Purpose: Application of sealants (silicone, acrylic, polyurethane) and adhesives from 310 ml cartridges for sealing seams, filling voids, insulation and fixation.
• Application: Construction and repair work, including installation of plumbing, windows, doors, roofing, sealing of joints in bathrooms, kitchens, facades.
• Cartridge volume: 310 ml (standard tube size: diameter ~ 5 cm, length ~ 21.5 cm).
• Types of construction:
  • Skeletal: Lightweight, with an open frame, suitable for one-time work, but less durable.
  • Semi-enclosure: Reinforced, with a partially enclosed body, allows for more precise application and durability.
  • Closed: Fully enclosed housing (usually aluminum), for professional use with high durability.
• Materials:
  • Body: Steel, aluminum or nylon (for light models).
  • Stem: Smooth round (diameter 6.5-8 mm) or hexagonal, for stepless sealant delivery.
  • Handle: Plastic or rubberized material for ergonomics.
• Features:
  • Smooth sealant delivery for neat seams.
  • The stem lock (in some models) prevents spontaneous movement.
  • Leak protection (in professional models).
  • A cutter for trimming the cartridge spout (on some models).
• Weight: ~200-500 g (depending on design and material).
• Tool length: ~22-24 cm (for 310 ml cartridges).
• Advantages:
  • Easy to use: just pull the trigger to deliver the sealant.
  • Precise dosing and uniform application.
  • Durability when choosing reinforced models (steel >2 mm).
  • Compact and easy to work in tight spaces.
• Disadvantages:
  • Skeletal models may wear out after 2-3 tubes (for one-time work).
  • Thorough cleaning is required after use to prevent the sealant from drying out.
  • For viscous sealants, reinforced or professional models are needed.

Application

• Surfaces: Concrete, brick, metal, wood, ceramic, plastic (subject to sealant compatibility).
• Areas of application:
  • Seam sealing in bathrooms, kitchens, showers.
  • Installation of windows, doors, plumbing.
  • Filling cracks and voids in building structures.
  • Roofing and façade works.
