VARO-70SA
- Single component with high performance, low odour, moisture curable polyurethane waterproofing membranes. Self-leveling PU for roller application to horizontal, exposed surfaces and provides long-life waterproof protection.
▶ TECHNICAL DATA
▶ Features
* One-pack, moisture curing system.
* Easy, fast application & repair by roller or brush.
* Good adhesion to the substrates.
* Good adhesion to the topcoat.
* Good persistence and chemical resistance.
▶ Uses
* General exposed areas for light traffic.
- Roof-deck, walkway, hallway, floor, etc.
* General exposed surfaces.
- Concrete, block, brick, tile, etc.
▶ Color
* Green, Grey
- Custom colors are available.
* Tend to yellowish and become chalking after exposure to UV light. It should be combined with Varo-Top HG for UV-resistance and durability

* 1.40kg/m in 1.0mm dry film thickness on a smooth surface.
* Recommended flilm thickness: 3mm.
▶ Packaging
* 22kg / Steel Pail.
▶ Storage
* Use within six(6) after manufacturing date written on the label.
* Store in cool, dry and well-ventilated place.
* Avoid exposure to humidity and UV.
* Avoid contamination by water, alcohol, etc.
* Keep away product from heat, spark and flames.
▶ Surface Preparation
* Surfaces must be sound, smooth and free from dust, laitance, oil or other contaminants.
▶ Application - Professional use only.
* Priming
- To inhibit pin-holes and increase the adhesion to the surfaces, porous surfaces should be coated by primer(Varo-BP is recommended) at 0.25kg/m in 0.1mm dry film thickness.
* Coating
- Apply VARO-70V membrane by roller or brush in two times(1.5mm respectively) up to 3.0mm coating thickness over the primed surface.
- Allow to dry fully between coats.
- Do not apply product unless concrete has cured at least 28days at 20C and over 80%RH or equivalent. The surfaces temperature and moisture content should be lower than 400 and 6%
- Do not apply product when the temperature is below 50
- Do not use on on heavy trafficable areas.
- Cover the fully dried membrabne by Varo-Top HG R/H for color-fast and endurance.
- Please refer to the general guideline for complete information.
