Vodicolor PUR

Elastic hygro-hardening polyurethane two-component waterproofing membrane in red or grey color. Under-tile coating, roof waterproofing, terrace and balcony waterproofing, old bituminous sheathing waterproofing.

Available versions




VODICOLOR PUR is a polyurethane resin-based liquid membrane with a low quantity of bitumen in solvent. The product (A+B), quickly vulcanizes, producing a very elastic and adhesive film with great physical and chemical properties and a good UV resistance.


Primary use

- Waterproofing of terraces and balconies
- Re-waterproofing of old bituminous membranes and metal roofing
- Waterproofing of any kind of roof, concrete surfaces of different shape
- Under slate waterproofing etc.


Application procedure


Treat all the surfaces where VODICOLOR PUR will be used, by applying about Kg. 0.300Kg/sqm of VODIRESIN PRIMER, avoiding product stagnation. Wait for the complete drying-up (about 20 minutes at 20°C).


VODICOLOR PUR is made up of 2 products separately packed (PART A + PART B) that, mixed together during the application, make a semi-fluid easily workable compound. Stir the product in the bigger can (A) after adding the resin (B) by using a mechanical paddle mixer. Wait for a few minutes before applying the product by means of a brush, a roller or spraying on completely dry and clean surfaces. The preparation of waterproofing will occur applying on the critical parts (corners, edges, cracks and joints) VODICOLOR PUR with the immediate overlapping of VODITES (60-80g/sqm) between the wall and the adjacent floor. Then the product will be applied on the whole horizontal surface. The performance of VODICOLOR PUR allows it to be used also as a SINGLE COAT PRODUCT using up to 3Kg per sq.mt. (it is always recommended to use two coats, especially in areas with high exposure to the sun). If the use of VODITES is needed on the whole surface, apply about 700g/sqm of product with the immediate overlapping and impregnation of the reinforcement fabric, making sure it is extended at least 5cm up the surface. Wait for the complete cross-linking of the product for about 2 hours at 20°C (cross-linking time may change according to temperature and humidity), then cover the reinforcement fabric, using the necessary quantity of VODICOLOR PUR per sq.mt.

Once mixed up (A+B), VODICOLOR PUR may be used for a limited time (about 30 minutes at a temperature of 20°C) but its cross-linking depends on relative humidity too. We suggest to prepare and use one can at a time. In case of great humidity or high temperature, it is possible to dilute the product (max. 15%) with our solvent VODISINT. Soon after the application, the use of a bubble-breaking roller on the still-wet surface is always recommended.



VODICOLOR PUR is solvent-based; apply the product only in well-ventilated areas. Keep away from sources of ignition. Do not eat or smoke when applying the product. Store the product in the original cans in open-air and dry places. Once mixed up (A+B), the product must be immediately used. For the application of the product at low temperatures (lower than +5°C), it is possible to use our accelerator CATAPUR to get a quicker vulcanization, mixing it slowly and uniformly for several minutes. The consumption depends on the temperature, it is from 0.05% to 0.2% (12ml to 50ml per can, previously diluted with a low quantity of VODISINT TK3, considering the total weight of 25Kg (A+B). Anyway we suggest to make some tests to understand the right quantity to use. At a temperature of 20°-25°C and a relative humidity of 50-60%, the product’s performance will be of 80-90% in 3-5 days; its complete cross-linking will be in 8-10 days.
