Sikalastic®-390 Membrane | Liquid-Applied Waterproofing Base Membrane

Liquid-Applied, Seamless Elastomeric Waterproofing Membrane | Brand: Sika

Sikalastic®-390 is a liquid-applied, seamless elastomeric waterproofing membrane that forms the base waterproofing layer of the Sikalastic®-3900 Traffic System. Applied over Sika MT Primer, it cures to a continuous, flexible film. Confirm coverage, film thickness, cure time and crack-bridging performance against the current Sika TDS, SDS and project specification before use.

Sikalastic®-3900 Traffic System component: the base waterproofing membrane, applied over MT Primer and beneath the Sikalastic®-391 N wear course. Confirm the full system build-up against the current Sika system specification.
Also available — ResinTech alternative

Prefer a locally stocked alternative? ResinTech FLEXCOAT-PU is a single-component elastomeric polyurethane waterproofing & crack-bridging base membrane, stocked in North Vancouver and used in the same base / liquid-applied waterproofing-membrane applications. Product chemistry and system build differ between manufacturers — confirm suitability against the current ResinTech TDS before substituting.

Key Characteristics

  • Liquid-applied membrane that cures to a seamless, elastomeric film.
  • Designed to accommodate substrate movement; confirm crack-bridging performance against the TDS.
  • Confirm wet and dry film thickness and coverage rate against the current TDS.
  • Confirm cure and recoat windows against the TDS (temperature- and humidity-dependent).

Typical Applications

  • Base waterproofing layer for vehicular and pedestrian traffic decks
  • Parkades, ramps and podium decks within the Sikalastic®-3900 Traffic System

Limitations

  • Must be applied over an approved primer as part of the Sika system.
  • Confirm substrate preparation requirements against the TDS.
  • Confirm number of coats and film build against the TDS.
  • Not a standalone wearing surface — requires the specified wear course and topcoat.
