Q. Is this all I need to protect my summer house?

Although this product can be used as a standalone treatment for summerhouses sheds, fences and other rough sawn or smooth timber structures, it has minimal durability and does not provide any weather protection for the wood. For a more durable finish and one that provides added water repellency and weather protection, we highly recommend that this product is overcoated with a suitable exterior wood oil such as Barrettine Log Cabin Treatment or Barrettine Decking Oil.

Q. Can I use Barrettine Wood Preservatives on a chicken shed and dog kennel?
