AVAL KM 16

Because of its optimum formulation, AVAL KM 16 provides excellent flexibility and adhesion at a competitive price.

Recommended for heavy duty applications – involving difficult substrates or exposure to adverse weather conditions.

Ideal for coverings exposed to deformations – highly flexible, the adhesive compensates:

• thermal stress - on balconies, in underfloor or wall heating systems (AVAL KM 17 (ATLAS PLUS), an S1 class adhesive is recommended for use on terraces),

• mechanical stress – on plasterboards, gypsum or cement-bound particleboard, and damp proof membranes, such as AVAL KL 51 (ATLAS WODER E) or ATLAS WODER DUO.

Enables tile fixing to difficult substrates - e.g. terrazzo.

Bed thickness between 2 and 10 mm - enables tile fixing to slightly uneven substrates.

Improved adhesion – at least 1 N/mm².

Fixing tiles from top to bottom thanks to reduced slip – optimum consistency and bed thickness, according to recommendations, eliminates slip and enables tile fixing from the top edge of the wall, thus eliminating the need to place cut tiles on the exposed surface.

AVAL KM 16 is manufactured as a dry mix of top quality cement binder, aggregate and specially selected modifiers.

 

The product conforms to EN 12004 + A1:2012 standard for C2TE class adhesive. EC Declaration of Performance No. KM 16/CPR.

The substrate should be:

• stable – sufficiently rigid and sufficiently long stabilized. The stabilizing time is, respectively:

- for new plasters made of ready-to-use ATLAS mortars - min. 1 week for each 1 cm of thickness,

− for ATLAS POSTAR 80, ATLAS SMS 15 and ATLAS SMS 30 subfloors – min. 24 hours,

− for ATLAS POSTAR 20 screed - min. 4-5 days,

− for self-leveling compounds ATLAS TERPLAN N or ATLAS TERPLAN R - min. 3 days

− for anhydrite jointless floors – at least 2 – 3 weeks,

− for concrete substrates, at least 28 days,

• dry or matt-wet,

• even – maximum adhesive thickness is 10 mm, for the substrate leveling use, e.g. ATLAS ZW 330 mortar,

• clean – free from layers that can deteriorate the adhesiveness, especially dust, dirt, lime, oils, greases, wax, residues of oil and emulsion paints; a substrate covered with algae, fungi, etc. must be cleaned with ATLAS MYKOS agent.

• primed with one of ATLAS primers:

Cement substrates:

−AVAL KT 17 (ATLAS UNI-GRUNT) or AVAL KN 97 (ATLAS UNI-GRUNT PLUS) – if the substrate is excessively absorptive,

−GRUNTO-PLAST – if the substrate absorptivity is low, or it is covered with layers limiting the strength of adhesion.

Gypsum plasters and anhydrite screeds strictly require, before tiles fixing, priming with AVAL KT 17 (ATLAS UNI-GRUNT) emulsion or ATLAS GRUNTO-PLAST compound.

Pour the adhesive from the bag into a container with the suitable amount of water (see Technical Data for proportions) and mix, using a drill with a mixer, until homogenous. The dispersed adhesive should be left to rest for 5 minutes and then remixed. So prepared adhesive should be used up within ca. 4 hours.

The adhesive should be applied to the surface with a steel trowel or a smooth float and then distributed evenly and shaped (possibly in one direction) using a notched trowel.

After the application, the adhesive retains its properties for ca. 30 minutes (at ambient temperature ca. 23 °C and 55 % humidity). Within this time, the tile must be placed and pressed well against it. The contact surface with the adhesive should be as large as possible - min. 2/3 of the surface of the tile. For floor tiles and for glazing made outdoors, it is recommended that the adhesion surface be complete. The excess of adhesive appearing in the joints in pressing the tiles should be removed immediately.

The position of a tile can be adjusted with delicate moving it along the bonding plane. It can be done for about 10 minutes after it is pressed (at temperature ca. 23 °C and 55 % humidity).

Foot traffic and grouting can start after approx. 24 hours from the tiles fixing. The adhesive achieves its functional strength after 3 days.

Average consumption: ca. 1.5 kg of dry mix / 1 m² / 1 mm adhesive layer – for complete filling the space under the tile. It depends on the smoothness of the surface and the bottom side of the tile.

 

• The tiles must not be soaked before fixing. When determining the adhesive thickness under the cladding, one should consider the geometric deviation of tiles shape, e.g. plane warpage. Tiles subject to discoulouration in contact with grey cement should be applied with the use of adhesives based on white cement binder.

• Open time – from the moment of application of the adhesive to the moment of placing the tiles upon it – is limited and depends on the absorptiveness of the substrate and temperature and humidity of the environment. In order to check if it is still possible to fix tiles, performing a test is recommended. It consists in pressing your fingers against the adhesive. If the adhesive remains on the fingers, you may fix tiles. If the fingers are clean, the old layer of the adhesive has to be removed and a new one applied.

• The tools must be cleaned with clean water directly after use. Difficult to remove residues of the set adhesive can be removed with the ATLAS SZOP agent.

• DANGER. Contains cement. May cause respiratory irritation. Causes skin irritation. Causes serious eye damage. May cause an allergic skin reaction. Keep out of reach of children. Avoid breathing dust. Wear protective gloves/protective clothing/eye protection/face protection. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. If skin irritation or a rash occurs: Get medical advice/attention. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing. Follow the instructions of the Safety Data Sheet.

• Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%.
