MasterSeal M 811 – Two component polyurea hybrid, pigmented, elastic, highly reactive, spray applied (machine application) waterproofing membrane with short curing time

How does MasterSeal M 811 work?

MasterSeal M 811 is a solvent free, two component polyurea hybrid waterproofing membrane. It is high reactive and needs to be applied by special, two component spray equipment (Mixing ratio 100 : 100 by volume).

What are MasterSeal M 811 typical applications?

MasterSeal M 811 is used in a wide range of waterproofing applications such as car park decks, podium decks, cut and cover tunneling, roofing and basement waterproofing. It is also used in some secondary containment applications.

Using the appropriate primer, MasterSeal M 811 can be applied to most substrates including concrete, steel, bitumen cement screed, glass reinforced polyester, timber etc.

What are MasterSeal M 811 main benefits?

fast reacting
high build capability
application to vertical surface without runs
easy application to complicated details
fast installation
monolithic – no laps, welds or seams
fully bonded
high water vapor permeability – low risk of blistering
excellent mechanical properties
excellent crack bridging
resistant to puncture
resistant to standing water
thermoset – does not soften at elevated temperatures
