Description

MasterSeal P 684 

Distinctiveness

1 component Wash Primer , containing solvent.

MasterSeal P 684 is a low-viscosity, solvent-based, pigmented 1-component adhesive primer for metal surfaces.

For use with MasterSeal M860 & M861 Polyurea

DESCRIPTION

MasterSeal M860 and M861 are hand applied, nonsolvented, 2-component, elastomeric polyurea coatings.

MasterSeal M860 is self-levelling.

MasterSeal M861 is thixotropic for applications to steeply sloping and vertical surfaces.

FIELD OF APPLICATION

MasterSeal M860 and M861 are used in a variety of concrete waterproofing applications including roofing, balconies, terraces, podium decks, car park decks and water industry applications.

Two-part, hand-applied, rapid-curing, hydrophobic and chemically resistant polyurea waterproofing membrane

When you have essential waterproofing requirements or repairs and need to get facilities back into service as quickly as possible, a fast-track waterproofing membrane can save money. MasterSeal is a two-part, hand-applied, rapid-curing polyurea membrane that enables structures to be recommissioned with minimal downtime. It provides long lasting waterproofing with high elasticity for thermal movement. As a seamless coating (no joints or overlaps) there is no risk of leaky joints with excellent crack-bridging and chemical resistance. 

MasterSeal - Polyurea can be easily and seamlessly applied by brush, roller or squeegee.

FEATURES AND BENEFITS

  • Monolithic – no laps, welds or seams
  • Fully bonded
  • High water vapour permeability
  • Excellent mechanical properties
  • Excellent crack bridging capability
  • Resistant to puncture
  • Resistant to standing water
  • Mhermoset – does not soften at high temperatures
  • Remains elastic at low temperatures eg approx. - 45ºC
  • Non-solvented
  • ​Rapid curing: accepts light foot traffic after 4 hours at 20ºC
  • Hydrophobic material, so waterproofs the roof instantly
  • Highly elastic, can bridge cracks
  • Non-slip top coat available 
  • High tensile and tear strength, meaning the membrane remains durable where others tear

MasterSeal M860 Typically 1.35kg/m² per mm thickness. Minimum membrane thickness: 1.5mm.

MasterSeal M861 Typically 1.05 kg/m² per mm thickness. Minimum membrane thickness: 1.5mm

    Benefits
    • Excellent adhesion
    • Short re-coating interval
    • Single component
    • Low viscosity
    • Easy to apply

    As part of the toolkit primers for the MasterSeal waterproofing systems for roofs and parking decks, MasterSeal P 684 complements the other MasterSeal P primers to ensure the adhesion of the waterproofing system to all substrates.

    • Fully bonded membrane systems prevent the water circulation between the layers even if there is a leakage, helping its detection, localization and repair.
    • Ensures the adhesion of the waterproofing membranes on aluminium, cooper, stainless steel and other non-ferrous metals.
    • Solves the adhesion problem that normal primers experience with the low porosity of metals.
