İZO-SEM 2K
2 component, stable, thick layer, solvent-free, polymer modified bitumen waterproofing coating.
| Description :
IZOSEM 2K is a two component, stable, solvent-free, crack- bridging, polymer modified bitumen coating. One component is modified bitumen emulsion, and second component is powder. IZOSEM 2K bridges cracks and resistant to ageing.
Uses : · Waterproofing of sub-base concrete structures · Waterproofing of foundations · Waterproofing of floor plates · Waterproofing for intermediate waterproofing of balconies, underneath screeds, wet and damp rooms · Bonding adhesive of insulation board · Bonding adhesive of drainage boards
Advantages: · Capability of crack bridging · Solvent and asbestos free · Suitable for both horizontal and vertical surfaces · No sagging on vertical surfaces · Resistant to rain after a short time · Flexible structure · Applicable for dry and partly damp surface

Surface Preparation :
The substrate should be slightly contains moist or dry, frost-free, free of oil, tar and loose particles. Defects and cavities on substrate surface must be repaired with relevant mortars.
Protruding mortar residues must be removed on substrate surface.
Application :
Primer application is advised before IZOSEM 2K application. The liquid component can be used as primer with dilution ratio of 1 volume bitumen based compound and 5 volume water in order to be applied by brush. The consumption of primer strictly depends on porosity of the substrate and be approximately 0.2-0.3 l/m².
Add the powder component to the liquid component and stir mixture extensively with appropriate stirring device until the mixture become lump free, and homogeneous. Electric drill with suitable stirrer can be used as stirring device. Mixture should be used in 1 to 2 hours. The time needed to apply the second layer depends on the ambient temperature, substrate characteristics, humidity, and thickness of previous layer. At normal conditions 2-4 hours are needed for over coating. During the drying period ( approx. 3 days), the coating must be protected from frost.
Dosage :
1,5 kg/m2 per layer minimum 2 layers
Storage :
Store in a cool and dry conditions (+5°C to +35°C). In closed original unopened pails, the material can be stored for approximately 6 months.
Package :
32 kg pails (24 kg of liquid component, 8 kg of powder component)
