Adhesive rubber mastic: characteristics and use

Adhesive rubber mastic - a universal building material... It is considered the most reliable bonding agent for various surfaces. The substance is actively used in solving household problems, at industrial construction sites, where it is important to have a strong connection of materials of different quality without the slightest gap.

KN-mastics are called rubber glue. It is based on indene-coumarone resins. Produced in cans, it has a homogeneous mass. The stability of the mass is ensured by the volatile solvents contained in the composition. If the container is left open, they evaporate, the mastic hardens, it cannot be diluted to the required viscosity. The technical properties of the glue are also lost.

It is produced in accordance with the requirements of GOST. The peculiarity of the glue is its close to natural ingredients, harmless to the person working with it. Mastic is prepared from the following products:

• synthetic rubber;
• solvent;
• fillers;
• polymer resins.

Adhesive rubber mastic has established itself as the most durable waterproof agent for joining different materials. Construction and repair work takes place without difficulty if KN mastics are used when joining heterogeneous materials. They securely join the trim elements on a pre-leveled base.

KN-3 glue was created specifically for plywood, which makes it possible to solve various construction and finishing tasks with a minimum of costs. The mastics are packed in hermetically sealed metal containers. Their consistency is viscous, color ranging from yellow-brown to black.

The additives used in the production of glue do not allow the development of mold and have bactericidal properties. The rubber provides the mastic with high adhesive properties. Fillers - plasticizers, modifiers - impart high plasticity to the mass. Solvents give the glue the consistency and viscosity required for work.

Various types of glue have been tested over 3 decades of use in construction work. It has excellent technical characteristics:

• reliable strength;
• excellent adhesion;
• water resistance;
• bio sustainability;
• withstands temperature extremes, retaining its properties.

KN-2 brand glue is used in construction, repair, and finishing works. KN-3 mastic is produced in the form of a pasty mass. Due to the presence of an adhesive base in it, it ensures reliable adhesion of various materials to the floor screed, concrete walls and ceilings.

Mastics are used in floor, decoration, wall, roofing works. Synthetic rubber easily and reliably glues different materials: drywall, plywood, hardboard, chipboard, which is ensured by the additional inclusion of plasticizers in the glue. The result is a reliable waterproof connection that is resistant to aggressive detergents, water, high and low temperatures. These features of the glue make it possible to use it in indoor and outdoor applications.

A ready-to-use mastic is produced. With its help, roll, tile, floor, roofing materials are reliably connected:

• PVC linoleums with and without a base;
• rubber linoleums;
• facing tiles;
• carpet.

Work with rubber mastic should be in a ventilated area, on a dry, free from dirt, dust, oil base. Stir the mastic thoroughly before starting work. After that, it is easy to apply to any surface. Recommended layer - 0.3 mm... It is recommended to apply glue with paint rollers, brushes, wooden spatulas. Porous elements should be coated with 2 layers with a break per day. The viscous mass fills any gaps in the parts to be bonded.
