no, it means any coatingthe sikkens web site says that previous coating must be removed prior to application. is this only if the previous coating was sikkens?
I just did a job using Dek a couple months ago
you need to read up on the website and follow it exactly
including removing the coating, the tsp, and the drying times, etc....if you dont, it can turn ugly and let's face it...that stuff is expensive
always do more during the prep portion if at any time :thumbsup:
brush it on and walk away...I love that stuff
