Cedar siding problem

Tracy PKMS Woodworks


We just cleaned our tight knot cedar siding. After cleaning we applied a wood restorer. After sealing it we now have white crystalline/ wood fiber all over. We have contacted the manufacturer. Sun Frog. We have used their products successfully in the past. This is the first time we used Born Again. Their wood restorer. Any suggestions appreciated

    The "wood fiber" issue sounds like a power washing failure to this often erodes away the softer wood and leaves these fibers. The white crystals sound like the product was not rinsed fully. I took a look at the Sunfrog site and looked up the MSDS for the born again. It contains oxalic acid which is the main ingredient in the "brightener" product I use from Penofin. You said you sealed it already? Ideally the residue should have been fully rinsed BEFORE the sealer was applied. I would see if you can rinse it some more with just the garden hose...not a power washer...some light scrubbing with a "deck brush" should help. decks and siding both fall into this care regime

    I honestly don't think people should ever pressure wash siding. It damages the siding (unless it's vinyl) and drives water behind it for all types of siding which is already a problem with vinyl as you usually can't tell that you have water behind the siding and trim until there is a huge problem.
