REVESTIDAN FINISH is a liquid-applied, thixotropic, permanent elastic, fiber-reinforced, cold applied and cold curing, one component polyurethane membrane used for long-lasting waterproofing and for complex roof details.
Cures by reaction with ground and air moisture.
Scope
- Zinc plumbing/work fixtures, flashing, edging, drains, etc.
- On occasions where the use of a blowtorch is dangerous.
- In areas that are difficult to access or with shapes and/or materials that are difficult to resolve with traditional solutions.
- PVC and EPDM waterproofing finishes on complex details.
- Treatment of bituminous waterproofing (SBS and APP) plasticised, sanded and with mineral self-protection.
- Treatment of bituminous waterproofing finishes (SBS and APP).
Advantages & Benefits

- Doughy consistency.
- Little thermal variation.
- Easy application.
- Great bonding.
- Great elasticity.
- High resistance to weathering.
- It maintains its properties between -30ºC and +80ºC.
- Thixotropic.
Support
- Steel.
- Plasticised and self-protected asphalt sheets.
- PVC sheets.
- Ceramic material.
- Concrete subsrates.
- Mortar subsrates.
Instruction for Use
Substrate preparation: Thorough preparation of the substrate is essential for an optimum and durable finish.
+ If necessary, the surface must be levelled with mortar.
+ In the case of plasticised asphalt sheets, the polyethylene finishing film shall be removed in the area where it is to be applied. To increase adhesion, the asphalt mastic can be melted and then saturated by sprinkling with silica sand (0.4-0.8 mm).
+ In the case of self-protected asphalt sheets in mineral granules, the surface should be brushed prior to application to remove poorly adhering granules.
+ In the case of metallic surfaces, no pre-treatment is necessary. In case of dirt (dust, grease, etc…) sanding and subsequent cleaning with Methyl Ethyl Ketone (MEK) may be necessary.
+ In case of plastic surfaces (PVC, etc…) it is recommended to pre-clean with Methyl Ethyl Ketone (MEK).
+ Once this first coat is dry, a second coat of the product is applied to a thickness of approximately 0.6-0.8 mm (approx. yield 1.25 kg/m²).
+ It may be necessary to apply a third coat.
Finishes of different waterproofing in complex details, plumbing fittings/zinc work, flashings, edges, drains, etc: Proceed as above.
- Type of substrate: REVESTIDAN FINISH is recommended for use on mortar and concrete, steel and aluminium, plasticised, sanded and self-protected asphalt sheets (slate finish) and PVC sheets.
- Condition of substrate: it must be dry and clean of dust, grease, paint residues, plaster and foreign bodies and any other product that hinders adhesion to the substrate.
- Preparation of the substrate:
+ If necessary, the surface must be levelled with mortar.
+ In the case of plasticised asphalt sheets, the polyethylene finishing film shall be removed in the area where it is to be applied. To increase adhesion, the asphalt mastic can be melted and then saturated by sprinkling with silica sand (0.4-0.8 mm).
+ In the case of self-protected asphalt sheets in mineral granules, the surface should be brushed prior to application to remove poorly adhering granules.
+ In the case of metallic surfaces, no pre-treatment is necessary. In case of dirt (dust, grease, etc…) sanding and subsequent cleaning with Methyl Ethyl Ketone (MEK) may be necessary.
+ In case of plastic surfaces (PVC, etc…) it is recommended to pre-clean with Methyl Ethyl Ketone (MEK).
- Substrate humidity: REVESTIDAN FINISH must be applied on dry surfaces, humidity degree < 5%. In the case of concrete, it must be cured for at least 28 days.
- Drying time: Depends on ambient temperature, sunshine and relative humidity.
- Minimum recommended waiting time between coats. One coat should be applied when the previous one is dry.
- Application tools: Flat brush (40 to 100 mm wide).
- Application temperature: REVESTIDAN FINISH must not be installed when the temperature is lower than + 5 ºC or higher than + 35 ºC.
- Substrate temperature: It must be higher than + 5 ºC. Treatment of finishes on bituminous waterproofing: parapets, machinery dwarfs, pipe penetrations, etc.
- The substrate is prepared according to the above mentioned instructions.
- REVESTIDAN FINISH is stirred well and slowly with a manual stirrer, never with a mechanical mixer.
- Apply at least 2 coats according to the following instructions:
+ Once this first coat is dry, a second coat of the product is applied to a thickness of approximately 0.6-0.8 mm (approx. yield 1.25 kg/m²).
+ It may be necessary to apply a third coat.
Finishes of different waterproofing in complex details, plumbing fittings/zinc work, flashings, edges, drains, etc: Proceed as above.
