Chemical Resistance

Splash & spillage of mineral acids, alkalies, aliphatic & aromatic solvents, salt, oil and water.

Joint Preparation

All foreign matter and concrete laitance must be removed by sawing and/or sandblasting prior to installation of sealant. Both concrete and steel joint surfaces should be dry and free of dust at time of installation. Steel-faced joints should also be free of paint primer, oil, etc.

Priming

PolySeal does NOT need a primer.

Mixing and Application

PolySeal is designed for application through mixing equipment capable of metering the components (2:1 by volume) and automatically mixing and extruding sealant.
