ADHESIVE FOR CERAMIC TILES,
FOR INTERIOR USE

USE

AVAL KM 9 is an adhesive designed for fixing wall and floor ceramic tiles, glazed tiles, terracotta. AVAL KM 9 can be used on the following substrates: cement plaster, cement-lime plaster, concrete, cement or anhydrite jointless floor, and rough surfaces made of bricks, blocks, hollow bricks and other similar ceramic or lime-sand materials. It is suitable for bricklaying and surface levelling as well as a surface-finishing coat. It is suitable for internal use with maximum thickness of the layer of 2÷5 mm.

PROPERTIES

Cementitious adhesive, unsuitable for external use AVAL KM 9 is a ready-to-use dry mix of top-quality cement binder, aggregates and modifying agents. Owing to its technical parameters, it is very efficient, convenient and easy to use. Optimum selection of consistency and thickness of adhesion layer in accordance with recommendations (for relevant conditions of mortar application) eliminate slip of newly adhered tiles. AVAL KM 9 is water-resistant.

SUBSTRATE PREPARATION

The substrate should be dry, stable, even and structurally sound i.e. strong enough; it should be free from anything that may weaken mortar adhesion, in particular dust, dirt, lime, oil, grease, wax, remains of emulsion and oil paint. It is recommended that any irregularities of substrates surface that prevent application of the appropriate layer thickness (2÷5 mm) of AVAL KM 9 should be adjusted with, for example, AVAL KM 41 levelling mortar, AVAL KT 111 plastering mix, AVAL KN 83 mortar, etc. If necessary, use AVAL KT 17 priming emulsion to reduce substrates excessive absorption. In case of applying the adhesive to unstable substrates of bearing capacity that can hardly be determined (e.g. dusty, difficult to clean), it is recommended to make an adhesion test, i.e. to adhere a tile and check the bonding after 48 hours.

ADHESIVE PREPARATION

In order to prepare the mortar, pour dry mortar into a container with suitable amount of water (in proportion: 0.21÷0.23 l of water for 1 kg of dry adhesive) and mix until homogenous. It is best to mix it mechanically, using a drill with a mixer. The adhesive is ready to use after 5 minutes and after remixing. It maintains its properties for ca. 3 hours.

APPLICATION

AVAL KM 9 is applied in a thin layer for tile fixing. Apply the adhesive to the prepared, primed substrate with a trowel or a smooth float made of steel and then distribute it evenly and shape it (possibly in one direction) using a notched trowel. Do not lay the mortar over excessively large surface because it maintains its adhesive properties for 10÷20 minutes (depending on the substrate and environment). In order to check if it is still possible to fix tiles, you should make a test, i.e. press the adhesive with your fingers. If the adhesive has remained on the fingers, you may fix tiles. If the fingers are clean, remove the old layer of the adhesive and apply a new one. After having spread the mortar place the tile and press it towards the substrate. Apply so much adhesive that when a tile is pressed down, its contact surface with the adhesive is even and as large as possible (min. 2/3 of tile surface). In case of floor tile fixing, it is recommended to ensure complete adhesion surface. To do that, apply the adhesive both on the substrate as we as on the other side of the tile. Tile position may be adjusted within 10 minutes afterwards. If grouting is to be carried out, remove excess of the adhesive when tiles are pressed towards the surface. The floor can be accessed or grouted no earlier than 24 hours after the tiles have been fixed; the adhesive achieves its full functional strength after 3 days. The information comprises basic instructions of product application and does not relieve users of responsibility for work in accordance with good construction practice and OHS regulations.

CONSUMPTION

On average 1.5 kg of the adhesive is used for 1 m2 for each 1 mm of the adhesive layer. In practice consumption depends on how smooth and even the substrate is and what type of tiles is applied. Approximate consumption of adhesive for selected types of tiles Type of tile Trowels notch size Thickness of adhesive layer Average consumption (kg/m2) Small tiles (up to 10x10 cm) of smooth or slightly profiled bottom surface 4.0 mm ca. 2.0÷3.0 mm 2.1÷4.5 Medium tiles (25x25 cm) of slightly profiled bottom surface 6.0÷8.0 mm ca. 2.5÷4.0 mm 2.65÷6.0 Large tiles (30x30 cm) of medium profiled bottom surface 8.0÷10.0 mm ca. 3.5÷5.0 mm 3.7÷7.5

TOOLS

A drill with a mixer, smooth and notched float made of steel. Wash the tools with clean water directly after use. Clean the remainder of the set mortar that is difficult to remove with AVAL KL 55 washing agent.
