You put an epoxy surface coat on your deck?

Or did you mean woodrich efc 38. J.

yes, i meant efc38.

That mild striper requires an oxalic acid wash, woodrich sels it as a brightner, if you dont use the wash the finish will not take in a positive way.

If you have some little whiskers show up after the two step process sand them off if you like with a random orbital/ 60 grit pads. J.
