DETAILS

Product Data: Form: Pasty; Appearance/Colour: White

Technical Data:

  • Chemical Base: Polyurethane modified Acrylic Dispersion
  • Density: 1.20 Kg/l @ 300C
  • Solid Content: Approx. 60% by weight
  • Tensile Strength:
    • Free Film= Approx. 1.25 N/mm2
    • With Geotextile Fleece= Expected approx. 12 N/mm2
  •  Elongation at break:
    • Free Film= Approx. 350%
    • With Geotextile Fleece= Expected approx. 40-60%

APPLICATION METHOD

Waterproofing without Geotextile Fleece

For UV-stable coating, for extending life of old roofs or as reflective coating to enhance Energy efficiency.

  • Build up: HS PU ROOFKOTE is applied in two undiluted coats over a primer coat .
  • Substrates: Concrete, metals, wood, tiles
  • Primer Coat:
    • Material : Water = 1: 1 by weight [Self Priming ]
    • Total thickness: ~ 0.3 – 0.5 mm [Primer Coat + 2 Undiluted Coats]
    • Total consumption: ~ 1.0 kg/m2

Waterproofing with Geotextile Fleece

For cost efficient waterproofing solutions in new construction and refurbishment projects.

  • Build up: HS PU ROOFKOTE is applied in two coats and reinforced with Geotextile Fleece and sealed with one or two additional coats of HS PU ROOFKOTE.
  • Substrates: Concrete, metals, wood, tiles
  • Primer Coat:
    • Material : Water = 1:1 by weight
    • Total thickness: ̴̴ 0.4 – 0.5 mm
    • Total consumption: ~ 1.2 kg/m2

Geotextile Fleece is applied at areas with high movements, irregular substrate or to bridge cracks, joints and seams on the substrate as well as for details.

DIRECTION FOR USE

Cementitious substrates: New concrete should be cured for at least 28 days and should have a Pull off strength ≥ 1.5 N/mm2Cementitious or mineral based substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and to achieve an open textured surface.

Loose friable material and weak concrete must be completely removed and surface defects such as blowholes and voids must be fully exposed. Repairs to the substrate, filling of joints, blowholes/voids and surface levelling must be carried out using appropriate products. High spots must be removed by grinding etc.

Out-gassing is a naturally occurring phenomenon of concrete that can produce pinholes in subsequently applied coatings. The concrete must be carefully assessed for moisture content, air entrapment, and surface finish prior to any coating work. Installing the membrane either when the concrete temperature is falling or stable can reduce outgassing. It is generally beneficial, therefore, to apply the embedment coat in the late afternoon or evening. Prime the substrate and always use a reinforced system as and when required.

Brick and stone: ortar joints must be sound and preferably flush pointed. Use localised reinforcement over joints and prime before applying HS PU ROOFKOTE.

Slates, tiles, etc.: Ensure all slates/tiles are sound and securely fastened, replacing obviously broken or missing sections. Fully glazed tiles must be abraded prior to priming and subsequent treatment with HS PU ROOFKOTE.

 Bituminous felt: Ensure that Bituminous felt is firmly adhered or mechanically fixed to the substrate. Bituminous felt should not contain any badly degraded areas. Prime and always use a totally reinforced system.

Bituminous coatings: Bituminous coatings should not have sticky or mobile surfaces, volatile mastic coatings, or old coal tar coatings. Prime and always use a totally reinforced system.

Metals: Metals must be in sound condition. Abrade exposed surfaces to reveal bright metal. Use localised reinforcement over joints and fixings.

Wooden substrates: Timber and timber based panel roof decks are to be in good condition, firmly adhered , or techanically fixed.

Paints/Coatings: Ensure the existing material is sound and firmly adhered. Remove any oxidized layers and use localised reinforcement over joints.

Shelf Life/Storage: In unopened, undamaged original container, protected from direct sunlight and frost. At +10C to +350C, shelf life is at-least 1 year from the date of manufacture. It is always advised to keep the materials away from direct sunlight for a prolonged period of time.

However ,since success of application of our products is dependent on number of factors, we only can be responsible for quality of our products at the time of dispatch. In the event of any doubt on any critical parameter, it is advisable to seek clarification from our technical personnel .

Safety Instructions: Accidental splashes onto skin must be washed off with water and soap . In contact with eyes or mucous membrane , rinse with clean warm water and seek medical attention without delay.

Ecology: Do not dispose of into water or soil , but it is advisable to do it as per local regulations .

Toxicity: Non-toxic under the relevant local health & safety codes
