   Yes, you are. You have to spot-treat the newly exposed wood.

   Is this SYP or another species?

   If SYP, a color shift indicates a manufacturing problem / defect. The point of PT process is to penetrate the full thickness of the lumber - thicker the board, longer the pressure treatment.

   PT SYP is the same color throughout the thickness.

   This would also indicate that every crosscut will expose untreated wood - not just the rips.

   I smell a rat and would return the lumber.

   If a species other than SYP, my comments may not be valid.

   Depends on the strength of the treatment. Most is .25 but salt water treatment is 2.5 [been a long time since I used salt water treated so don't hold me to that]. The higher number is higher concentration and deeper penetration. You can still get CCA here for salt water applications. Most demensional lumber is .25 or .40 which is ground contact I believe.

   SYP ACQ surfaces will turn darker in sunlight than the interior. I cut some 6X6 ACQ the other day and it was somewhat green all the way through, so the penetration must be pretty good. Pulled some treated posts out of the ground last week that had been there ten years, and they were stll sound.

   I have worked with pressure treated wood for almost 20 years and have rarely found many pieces with the treatment fully penetrated through the wood.

   Your lumber retailer will sell a product (usually a pressure treated green preservative) that you are supposed to brush onto any of your cuts to meet the warranty of the pressure treated product.

   Your lumber retailer will sell a product

   I have found here in NW Oh. that products available are minimal. Cuprinol used to have a decent product for treatment of cut ends. VOC regs I think have limited those that are available.

   In addition to treating cuts I'd smear tar on cut ends in the ground.

   One of the many reasons I dislike building decks.
