Waterproofing and Coating Solutions for UV Resistant Terrace Roofs

Surface Preparation

The reinforced concrete application surface must be checked before waterproofing. The surface is free of residues that will prevent adhesion, clean, smooth and sound. The roof terrace slope should be designed as min 2%. Waterproofing system with protection and supporting layers (if any); should be able to withstand the effects of roof slope. The points (sieves and pipes) where the water onto the roof terrace to be discharged should be determined according to the roof area and annual rainfall quantity of the area where the application is made.

Reinforced concrete surface should be properly levelled for homogeneous application of the waterproofing product. If there are defects on the application sub-surface, it should be repaired with 4002 Tamirart 30 thick repair mortar. If there are structural cracks on the surface, 4004 Tamirart S40 should be used. Waterproofing must be ensured by using 4004 Tamirart S40 repair mortar on inner corners for sustaining the sealing. Before application, the surface should not be washed with water and the surface moisture should be below 5%. 3452 Izopur P should be applied after surface preparation.

Waterproofing Application

The most important feature of Izopur System components, that distinguishes them from other waterproofing products, is the high elasticity. Thanks to its easy and fast application it creates a water impermeable waterproofing layer at any place in need of waterproofing such as terraces, balconies, roof and terraces of the carparks. It provides long-lasting and reliable waterproofing with different compositions offered in the system for any areas with light vehicle traffic such as pedestrian crossings, pedestrian areas and with heavy vehicle traffic such as stadium, sports fields, industrial areas etc., with no needs to cover such areas.

Before application on flat roof terraces, 2 layers of 3451 Izopur one component, ready to use, extra elastic, polyurethane based waterproofing material should be applied by means of a brush, roller or by spraying on the reinforced concrete prepared surface primed with 3452 Izopur P. Risky areas such as large planes, floor-wall joints, parapet corners, chimney bottoms should be strengthened with a special waterproofing textile mesh. The second layer should be applied 12 hours after the application of the first coat (within 36 hours at the latest). After the surface dries, it should be waited for 7 days for full setting and leak-tightness tests should be carried out for 24 hours.

Finishing Coat Application

When surface finishing resistant to UV rays and light pedestrian traffic is desired, 2 layers of 3453 Izopur C, elastic, yellowing-free, easy to clean, finishing material must be applied on 3451 Izopur waterproofing material. The waiting period between two layer applications must be 3-4 hours.
