[TowerTalk] Is sealer required for top of concrete tower base ??

[Bob K6UJ]

Jim,

Most of us just leave the tower footing alone with no problems.
The sealer really isnt necessary for a concrete foundation.
A typical usage is  for concrete floors where it is planned to paint or apply a floor covering over the concrete.  The sealer 
prevents the moisture from wicking up to the surface of the concrete.  Also a vapor barrier is placed down before the concrete is poured to
minimize water absorption.   I think it would be best to leave it alone so it can breathe
when it rains as you said.
