Product Specifications
Applications
Liquid-applied air barrier for robust connections, pitched windows sills and other detailing. VISCONN can be brushed, rolled or sprayed on as a liquid film and forms a seamless, elastic, air and vapour variable membrane once dry.
Coverage
10L (2.5 Gallons)/ container
Coverage per container:
~11.5 m2 (125ft2) when applied with brush
~16 m2 (170ft2) when applied with airless sprayer
[coverage dependent upon applied thickness]
Advantages
- Time-saving airsealing of difficult junction because of airless spray/brush application
- Reliable bonding thanks to excellent adhesive properties on all standard construction surfaces
- Can be plastered/painted over, Pro Clima adhesive tapes can be bonded onto it (and can be sprayed over all TESCON/CONTEGA Pro Clima tapes)
- Appropriate for interior and exterior areas shielded from UV/direct weather exposure thanks to its vapour-variability
- Excellent values in the hazardous substance test, has been tested according to the AgBB evaluation scheme / ISO 16000
- Use appropriate safety protection when using airless sprayer
Substrates
- Apply to walls, ceilings and floor surfaces, such as masonry, CMU, wood sheathing, fiberboard, joists or joist bays
- Reliably fills gaps of 1/8”; deeper joints or thick coats result in longer cure times
- Highly porous/uneven materials require 2 or more coats for reliable coverage/airsealing
- It may be necessary to apply more than one coat in the case of uneven or rough subsurfaces
Properties
- Material: Aqueous acrylic dispersion
- Temperature resistance: -40°C to 80°C
- Perm Rating: 0.5 perms (6.11m ±0.6 m) at 11 mils (0.3 mm) thickness EN 1931
- Vapour Variability Range: 0.33 to 25 perms (0.13 – 10.00 m) ISO 12572
- Because of viscosity, recommended airless sprayers: Graco classic-hiboy 390,395, 490,495, GX21ProX and XForce HD with 3/17. 3/19 or 3/25 tips
- UV/weather Resistance: 3 months of exposure
