Estrella from Northridge, Ca writes,
Can I use PenaShield on pressure treated wood and then apply Thompson's Water Seal?
Yes, you can apply PenaShield to pressure treated wood, and once it has dried you can apply a water sealant. Allow PenaShield-treated wood to dry completely (at least 24 hours) before applying any protective finish. Protective finish must be applied within 2 weeks of treatment.
