Hi guys,

Today I decided that my pilothouse floors aren't looking too good and started to sand them down in preparation for re-coating with Polyurethane.

I noticed that there are a few areas where the black sealant between the planks is missing.

Is this black silicone, sikaflex or something other?

Also, I am guessing that I would inject the sealant, then resend, then polyurethane in that order. Make sense?
