Mapei Planiseal PMB

Planiseal PMB is a single-component, moisture-curing polyurethane compound that may be applied in a single or double coat to guard against moisture vapor emission from wet concrete surfaces and to act as a vapor retarder over wood substrates. When used in a double-coat manner with dry sand, it also functions as a bonding agent and moisture barrier system for self-leveling underlayments.
