Mastic for steel column/base plate protection

Mastic for steel column/base plate protection

Mastic for steel column/base plate protection

(OP)
Hello all,

We typically call for the column, base plate, and anchors to be coated with mastic when below grade for corrosion protection. Does anyone know of a good product for this type of application? We generally just leave it up to the contractor, but I am being asked to specify a specific mastic. Any suggestions?

D.S. Brown has a spray on membrane called Deckguard. Although it's a concrete deck product railroads use it to waterproof ballast plates on thru girder bridges. I know another product but the name escapes me at the moment. When I get home I'll find it. It's a similar product used on railroad bridges.

The other product I mentioned is Eliminator HM by Stirling Lloyd.

Avoid tar modified epoxies that can be carcinogenic.
