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

    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​
