MasterSeal M 266 A liquid applied below grade two-component polyurethane waterproofing coating

Formerly: MASTERSEAL 666

How does MasterSeal M 266 work?

MasterSeal M 266 is a two-component polyurethane liquid applied coating. Once applied MasterSeal M 266 makes an effective elastomeric water-proofing membrane.

As is common with all liquid applied waterproofing membranes MasterSeal M 266 should be applied in two coats to minimise the risk of a discontinuity in the membrane. In below ground structures, wet areas and roofs the applied dry film thickness of both coats should be 1.2mm. Where a superior performance is required the material can be reinforced with a layer of glass fibre mesh, each coat encapsulating the mesh should be a minimum of 1mm dry film thickness.

What is MasterSeal M 266 used for?

MasterSeal M 266 is recommended for waterproofing and damp proofing applications in:

  • basements,
  • bathrooms,
  • kitchens,
  • pools,
  • refrigeration storage,
  • roofs.

What are the benefits of MasterSeal M 266?

MasterSeal M 266 offers the following advantages:

  • High bond strength
  • High tensile strength and elongation
  • High build application in a single layer, but two coat application is always recommended
  • High solid content
  • Chemical cure, does not need the presence of moisture
  • Corrosion resistant, mildew proof and frost-resistant
