ISOMAT TILES ADHESIVE AK-16 25KG WHITE

ISOMAT AK16 is a high performance, cement base polymer-modified adhesive. It offers high
initial and final adhesive strength and resistance to moisture. It is qualified as absolutely non-slip and shows increased open time.
It is classified as type C2TE adhesive according to EN 12004.

Fields of application
ISOMAT AK 16 is suitable for fixing absorbent or non-absorbent tiles (e.g. “gres porcellanato”), on walls or floors on various
substrates, especially where particularly high adhesion, elasticity and moisture resistance are required. It is suitable for indoor or outdoor
use.

Directions for use

1. Substrate preparation
The surface to be overlaid must be clean, free of dust, grease, paint, loose material etc.
Dampening of the substrate before application is recommended.

2. Application
ISOMAT AK 16 is gradually added into water under continuous stirring, until a uniform paste
is formed. A low revolution mixer is recommended for mixing. The mixture should be left about 10 minutes to
settle and should be stirred slightly again. The tile adhesive should be spread (“combed”) on
the substrate using a notched trowel, in order to be uniformly applied on the whole surface.
The tiles should be fixed by pressing them in the desired position. The applied mixture must be covered with tiles
within 30 minutes in order to avoid “skin” formation, i.e. before the adhesive film starts setting.

Elastification
For tiling on unstable substrates subject to vibrations or contraction-expansion effects,
such as gypsum boards, chipboards, in-floor heating floors, terraces, balconies etc. it is
necessary that the tile adhesive be elastified with the addition of 5-10 kg of ADIFLEX-B to
25 kg of ISOMAT AK 16 plus a quantity of water depending on the desired workability.

Consumption
1.5-4.0 kg/m2, depending on the trowel’s notch size and the nature of the substrate.
