Kilz used on bare wood weathered deck, do i try to remove or paint ove

Don't remove it. Make sure your whole deck is painted with it, even underneath it, if possible. Kilz helps prevent mold and mildew. Then you can leave the deck bare, or stain and seal it. You could even prime and paint the deck. Best wishes 😇

i would get a good outdoor primer and then paint over it

Kilz is a great primer, kerp it there, even paint the underside!

Our cohort may be unabashedly pro-Kilz, but what look do you want?

If you want a natural weathered look, power wash to remover all the Kilz with Dawn/Fairy original blue dish soap & then rise all with 10% bleach-water. Use a palm sander to go after any splinter bits. You can follow this up with a semi-annual bleach wash to protect against mold etc.

If, on the other hand, you want your deck to get its patina slower, follow your sanding with 2 coats of clear water sealer. (My family always used Thompson's, but there are many good brands.) Then, each spring, do a bleach wash & add another coat of sealant once dry.

You can add sheer or opaque color by picking a colored sealant.

If you want to maintain your painted look, you can paint over your old Kilz if it is mostly intact. If not, power wash to remove old paint, let dry, reprime all surfaces with Kilz or Kilz2, dry, and then cover with porch paint with anti-slip grit. Cover with clear sealant, also with grit mixed in

You can refresh the painted look annually with more grit-infused sealant.

You don't need to remove it first
