Adhesive mixture for facing fireplaces, stoves and "warm" floors — TM 21 THERMO

Field of application:

For facing fireplaces, stoves, as well as heated floors with all types of ceramic tiles and other facing materials with a water absorption of less than 1% and a size of no more than 600*600 mm inside and outside the premises. It has high adhesion to various bases, thermal stability ensures stable operation up to 180°C, the appropriate composition ensures a highly elastic state during thermal expansion.

Features:

high adhesion to the base;
excellent rheological properties;
withstands internal mechanical deformation.

Advantages:

High fixing ability

Water and frost resistant

For warm floors

up to 180 °C

Heat resistant

Preparation of the base

The foundation is prepared in accordance with DSTU-NB A.3.1- 23:2013 and DSTU-NB V.2.6-212:2016. The surface of the base must be dry, strong, even, with low and uniform water absorption. Before applying the dry mixture, the surface is cleaned of dust, oil stains and other substances that reduce adhesion. Surfaces made of porous concrete, as well as gypsum and smooth concrete surfaces should be treated with a primer. Leave primed surfaces for at least 4 hours before starting cladding.
Preparation of the solution

Preparation of mortar mixture: pour water into a clean container (water temperature from +15 °C to +25 °C) at the rate of 0.24-0.26 l (l) per 1 kg (kg) of dry mixture (6.0-6 .5 l (l) per 25 kg (kg)), gradually add the dry mixture and mix with a low-speed mixer until a homogeneous mass without lumps is obtained. After 5 minutes mix again.
Recommendations

The use of dry mixture is recommended at temperatures from +5 °C to +30 °C and relative air humidity not higher than 65%. Eyes and skin should be protected during work. If the mixture gets into the eyes, it is necessary to immediately wash them with water and consult a doctor.

On bases with deformation seams, the latter must be additionally duplicated in the facing, followed by their filling with elastic sealants. When performing exterior work, a combined method is used for fixing tiles: the mortar mixture is applied to the surface in a layer, the thickness of which should correspond to the size of the grater tooth, and to the tile in a layer of up to 1 mm, evenly over the entire surface.

Execution of works

The mortar mixture is applied in a thin layer to the prepared base using a metal spatula or grater and smoothed with a toothed spatula. At one time, such amount of solution is applied that can be used within 15 minutes. The tile was not previously repl
Packaging

Paper bags with an inner polyethylene layer of 25 kg.
Storage

The mixture must be stored in original branded sealed package in a dry room, on pallets. The shelf life is 12 months from the date of manufacture indicated on the package.
Cost

On average, 1.6 kg of glue is used per 1 m², depending on the thickness of the applied layer and the condition of the surface.
