ISOMAT AK-25 is suitable for fixing all types of wall and floor tiles, including absorbent and non-absorbent tiles (e.g. gres porcellanato), natural stone, decorative bricks, large-format tiles, etc. Well-suited for applications where ultra flexibility, high adhesion and moisture resistance are required and for substrates subject to movement due to expansion/contraction or vibration, such as balconies, flat roofs, heated floors, metal surfaces, wood floors, old tile layers, swimming pools, gypsum boards, etc. For indoor and outdoor applications.

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

Application
ISOMAT AK-25 is gradually added to water under continuous stirring, until a uniform paste is formed. A low-speed mixer is recommended for mixing. The mixture should be left to stand for about 5 minutes, before is slightly stirred again. The tile adhesive should be uniformly applied over the entire surface with a notched trowel. Tiles should be firmly fixed to the desired position. The applied mixture must be covered with tiles within 30 minutes to avoid film formation, i.e. before the adhesive film starts to set.
