Re: Refinishing Speaker Cabs
It does adhere to Latex's but how that base coat of latex is applied has a lot do do with how tough the finish will end up. If the base coat of Latex (lets assume were talking home exterior Latex paint)is not applied very well the weakest point of course would be the initial adhesion of the Latex to the primer or the primer to the bare wood.If the base coat is applied well then sanding that should yield a very good bond to the Duratex even on oil based paints.
I would definitely sand any fully cured base coat you apply the Duratex on top of.
The roller grade works well and yields very good coverage.
I know a few guys who like to stretch the soup so to speak so they always primer with a water born primer prior to using Duratex.They sand the primer and then they usually get away with one thick coat using a hopper gun and spray grade Duratex.
I have oil heat in my home and one room in my basement has the Oil Burner/Tanks etc. along with a stack heater vented to that room.After painting cabs I place them in there for 2-3 days as it stays pretty toasty (around 78F)and is generally nice and dry.
I use a standard 72 hrs. till handling the cabs.
