Practical coverage at recommended film thickness
A spread rate of 12.00 sq. meters per litre corresponds to 0 microns dry film thickness assuming no loss. Practical spreading rates will vary due to such factors as method and conditions of application and surface roughness.
Apply a 2nd coat prior to painting for increased protection. Allow to dry.
