SILCOR® 900MP

Rapid-set, spray-applied, liquid waterproofing membrane for roofs, podium decks, terraces etc.

Product Description

SILCOR® 900MP is a premium performance two-component spray-applied seamless waterproofing membrane that rapidly cures to form a high-strength, elastomeric, and fully-bonded waterproof membrane. Unlike conventional liquid membranes, Silcor 900MP is extremely durable with excellent wear and chemical resistance and does not normally require additional protection against mechanical damage.

Principal Applications

New and remedial waterproofing for:

  • Roofs
  • Podium decks
  • Terraces
  • Walkways and foot bridges
  • Balconies
  • Green/ Planted roofs
  • Water features/ planters

System Components

  • SILCOR® 900MP – premium performance two component, spray-applied seamless waterproofing membrane.
  • SILCOR® Primer EP LT – three-component epoxy primer fast curing at low temperatures for use 0°C - 20°C.
  • SILCOR® Primer EPF – two-component epoxy primer for concrete substrates.
  • SILCOR® Primer MT – two-component phosphate/epoxy primer for metal substrates.
  • SILCOR® Primer PU 30 - 1 component polyurethane primer for bitumen sheets (mineralised face).
  • Dry Quartz Silica Sand – fine dry silica quartz sand for use with primers. Contact GCP for specification.
  • Hydroduct® 200/ 650 (optional) – geocomposite drainage/ irrigation sheet.
  • Hydroduct® Root Barrier (optional)

Design

Silcor 900MP spray-applied roof waterproofing system is satisfactory for use as a fully adhered waterproofing layer on new and existing flat (including those with zero pitch) and sloping protected roof specifications e.g. inverted roofs, terraces, podium decks and covered walkways for pedestrian access.

Compatibility/Adhesion

Concrete and steel surfaces must be suitably prepared to accept primers and membranes to ensure adequate adhesion. Mechanical preparation recommended. For further details concerning surface preparation guidelines and primer choice, contact GCP.

Installation

Silcor 900MP liquid waterproofing is applied only by experienced, trained contractors. Contact GCP for further details.
Silcor 900MP should only be applied to correctly prepared and primed surfaces in dry conditions. Surfaces should be clean, dry,and free of contaminants and loose particles. Consult GCP for surface preparation guidance and the requirement for mechanical preparation of specific substrates.
