MasterTop VB 240FS

Fast-setting, moisture vapor barrier system for use with resinous floor coatings

How does MasterTop VB 240FS work?

MasterTop VB 240FS is a fast setting, 100% solids epoxy moisture mitigation system for use with resinous flooring systems. MASTERTOP VB 240FS reduces the permeance of moisture vapor through concrete substrates to levels that are acceptable for the installation of resinous floor coatings. When used in conjunction with Master Builders Solutions seamless flooring systems, MASTERTOP VB 240FS helps provide a durable, sanitary flooring solution to meet the specific needs of each facility.

Recommended uses:

Where vapor drive of porous concrete surfaces needs to be controlled
Concrete floors and slabs with a compressive strength of at least 2500 psi
Where moisture vapor transmission of substrate falls between 3 lbs and 15 lbs per 1000 ft² over 24 hours using calcium chloride test per ASTM F 1869
Where the relative humidity of the concrete substrate is between 75% and up to 99% per ASTM F 2170 or F 2420 (see appropriate RH Level Chart)
