The combination of special rubber and the millions of fine fibers in the composition gives the ability of the obtained membrane to deform along with the substrate, without crackings and loosing adhesion, regardless of the weather conditions and the temperature changes. “Isomax ELASTA” is quickly and easily applied by a brush. The coating dries for about 4 hours; it facilitates the technology of application and it saves time and labor. Furthermore, it lets the foundation to breathe. The waterproofing with “Isomax ELASTA” is resistant to the hazardous impact of the UV radiation , thanks to it’s specific structure (small bituminous drops, protected by a layer of inorganic emulsifier), which provides tested durability of the material of over 15 years. Incombustible and ecological. The product does not contain any organic solvents, it is not fire hazardous and is safe for the health and environment.

The quality characteristics of “Isomax ELASTA” are guaranteed with the precise observation of the technology of placement:


The surface, over which “Isomax ELASTA” will be placed, have to be well cleaned. The critical locations should be marked WITH color spray, chalk or in another convenient manner. Repair the unstuck seams, joints, cracks, bubbles, boards and sections, with more advanced stage of damages, through strengthening with reinforcing material – polyester veil or mesh and paste “Isomax ELASTA”. Thus treated, these locations become the most solid and secure sections over the entire roof.


1. With brush, with long hairs, spread “Eco-primer ISOMAX” over the entire surface. Wait for the full drying, about 20 min.
2. Spread a layer of Isomax ELASTA, place the reinforcing material tightly(polyester veil or fiber-glass net) without leaving any wrinkles and spread again a layer of Isomax ELASTA again. Wait for the full drying. About 4  hours.
3. Spread a leveling layer of ISOMAX-Elasta. Wait for the full drying.
4. Spread a sealing of layer ISOMAX-Elasta. Wait for the full drying.
5. It is recommended to protect the insolation with layer of coloured Isomax ELASTA (only 0,2 kg/m2), which gives even more UV-rays resistance and also esthetic appearance.

* Protect from precipitation and freezing up to the drying of the coating!
** The thickness of each layer Isomax ELASTA is about 1,5 mm.
