ISOMAT AK-9 is a cement-based tiles adhesive. It provides high initial and final adhesive strength and moisture resistance. Certified according to EN 12004 and classified as type C1 adhesive. CE marked. ISOMAT AK-9 is suitable for fixing ceramic wall and floor tiles to a variety of substrates including concrete, brickwork, plaster, etc. For interior and exterior tile grouting applications.
Substrate
The surface to be overlaid must be clean, free of dust, grease, paint, loose material, etc. It is recommended that the substrate be dampened prior to application.
Application
ISOMAT AK-9 is gradually added to water under continuous stirring, until a uniform paste is formed. A low-speed mixer is recommended for mixing. A low-speed mixer is recommended for mixing. The mixture should be stirred slightly again. The tile adhesive should be spread and “combed” on the substrate using a notched trowel, in order to be uniformly applied over the entire surface. The tiles should be firmly pressed to the desired position. The applied mixture must be covered with tiles within 20 minutes to avoid “skin” formation, i.e. before the adhesive film stars setting.
In cases where additional adhesion or flexibility is required, such as unstable substrates subject to vibration or expansion/contraction effects (e.g. gypsum boards, chipboards, heated floors, terraces, balconies, etc.), it is necessary to add up to 3.15 kg of ADIFLEX-B to 25 kg of ISOMAT AK-9, plus the amount of water needed to obtain the desired workability, so that the tile adhesive becomes more flexible.
