ISOMAT AK-T 35 is a fiber-reinforced, cement-based adhesive, enhanced with polymers (resins), with no vertical slip and extended open time. Provides high initial and final adhesive strength, flexibility and resistance to moisture. Certified according to EN 998-1 and classified as a GP CS IV W2 rendering mortar. CE marked. ISOMAT AK-T35 has received an Environmental Product Declaration (EPD) following an assessment of its life-cycle environmental impacts. Registration No: S-P-09182, The International EPD System.
ISOMAT AK-T35 forms part of external thermal insulation systems when used in combination with MARMOCRET-PLUS and MARMOCRYL premium renders. It is used for bonding thermal insulation boards of extrudeed or expanded polystyrene, mineral wool, polyurethane, etc. to facades made of concrete, render, or masonry. It is suitable also for indoor applications. Moreover, ISOMAT AK-T35 can be applied to facade insulation boards with reinforcing fiberglass mesh, serving as the ideal substrate for the subsequent coat of render.

Substrate preparation
The surface to be covered with boards should be free of dust, grease, loose particles, paints, etc. It is recommended to dampen it before application.

Application
As adhesive:
ISOMAT AK-T35 is slowly added to water under continuous stirring, until a homogeneous paste is formed. A low-speed mixer is recommended for mixing. The mixture should be left to rest for about 5 minutes before is stirred again for a bit.

Smooth substrate: The adhesive is evenly spread and combed over the entire surface using a notched trowel.
Uneven substrate: The adhesive is applied in strips around the edges of the board and in selected dabs in the center using a trowel. Next, thermal insulation boards are firmly pressed to the desired position.
As reinforced mortar:
First, the material is applied with a smooth trowel at a maximum thickness of 3-4 mm. Then, a reinforcing fiberglass mesh is placed and firmly embedded into the fresh base coat layer with a smooth trowel. Finally, the surface is smoothed out and the excess adhesive is removed.
