Vodipren 2PUR Black

Features

VODIPREN 2PUR is a polyurethane resin based liquid membrane with a low quantity of bitumen distilled in solvent. The product (A+B), quickly vulcanizes, producing a very elastic and adhesive film with great physical and chemical properties and a very good UV resistance. The presence of adhesion promoters allows the application on wet areas too.

 

Primary use

- Waterproofing of terraces and balconies
- Re-waterproofing of old bituminous membranes and metal roofing
- Waterproofing of roofs and flat concrete surfaces of different shapes
- Roof gardens
- Under slate waterproofing etc.

 

Instructions for use


Primer

Treat all the surfaces where VODIPREN 2PUR BLACK will be used, by applying approximately 0,350 kg./sq.mt. of VODIPRIMER, avoiding product stagnation. Wait for the product to dry completely.

Mix

VODIPREN 2PUR BLACK 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) VODIPREN 2PUR BLACK with the immediate overlapping of VODITES (gr. 60-80/sq.mt.) between the wall and the adjacent floor. Then the product will be applied on the whole horizontal surface. For green roofs we recommend the use of our VODITES reinforcement fabric on the whole surface. If the use of VODITES is needed on the whole surface, apply about gr. 700/sq.mt. of product with the immediate overlapping and impregnation of the reinforcement fabric, making sure it is extended at least cm. 5 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 VODIPREN 2PUR BLACK per sq.mt. The performance of VODIPREN 2PUR BLACK allows it to be used also as a SINGLE COAT PRODUCT using up to 3Kg per sq.mt. (anyway we always recommend two coats, above all in presence of great solar radiation). The dry film has a fair UV resistance so, after its cross-linking (at least 15 days), we suggest to cover it with a coat of VODICOLOR TOP, applying it by roller, brush or spraying. The tools may be cleaned using the thinner VODISINT before the product gets dry.

Beware

Once mixed up (A+B), VODIPREN 2PUR BLACK 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. 10%) with our solvent VODISINT. Soon after the application, the use of a bubble-breaking roller on the still-wet surface is always recommended.

 

Precautions

VODIPREN 2PUR BLACK 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 +10°C), it is possible to use our accelerator CATAPUR to get a quicker vulcanization, mixing it slowly and uniformly for some minutes. The consumption depends on the temperature, it is from 0,05% to 0,2% (from ml. 12 to ml. 50 per can, previously diluted with a low quantity of VODISINT), considering the total weight of Kg. 25 (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.
