IZ- 535 Faundation Insulation

1k- Bitumen

Water based bitumen, silicone modified faundation insulation
material. It can easily be applied on plaster, exposed concrete, asbestos, cement slab
surfaces. Resistant against positive water pressure. It is used as double component by
addition of 20-30% Cement.

  • Elastomeric structure (200%) and does not crack under temperature differences,surface movements and fills the capillary cracks

Used in horizontal and vertical applications in the indoor and outdoor spaces.

  • At places such as foundation – retaining walls and basement insulation which are subject to movement, vibration and slight settlement ,
  • Terraces, balconies, roofs, manholes, concrete pipes and flower beds.


The surfaces should be cleaned off dust and dirt. Silicone Lac should be applied as 1 coat by at least 50% thinning before the application in the old and new buildings.

Cement can be added by low cycle mixer. Then, IZ-535 Base Insulation is applied as 2 coats without thinning. Each coat applied is applied maximum within 48 hours following the application of the previous coat. Each coat should be applied or sprayed in one direction. The final coat should be applied perpendicular to the brush, roller or spraying direction applied during the previous coat. When it dries, it forms a hard, seamless insulation layer, elastic like linoleum. The mixture should be used within 30 minutes. Recoats time is 24 hours at +20ÅãC.

For the best result: It is recommended to use plaster or satin plaster net between the coats against impacts and abrasion on the surfaces with heavy traffic. Cement addition; white cement mixed with water is then mixed within Extra insulation.

Dry-Time (20°C): Touch Dry :3-5 hours Full Dry : 24 hours

The final resistance is acquired after 14 days.

Please protect from rain, freeze, frost and rime for at least 36 hours after application.

Consumption: 1,000 – 1,250 L/m2 for 2 coats.
