Prepdeck stripper/cleaner is a professional, high-grade product specially designed for the removing of old solid and semi-transparent stains, unsightly grade stamps and other finishes from wood. When diluted it makes a powerful cleaner for removing dirt and other surface contaminants from weathered woods.

Using Prepdeck is a fast and easy way to reduce mill glaze, (a shiny surface on new timber created through the milling process) which is essential to remove to help with the penetrating power of your wanted wood finish, for the best possible result.

Why Should I Use Prepdeck?

Prepdeck is a powerful and versatile wood stripper. It can thoroughly strip away old finishes to prepare wood for new treatments, get rid of even well-established stains along with other marks such as grade stamps, and provides an extremely effective cleaning action.

It is suitable for use on a wide variety of softwoods and hardwoods and is suitable for almost any exterior wood surface. It can treat decking, fences, sheds and other buildings, garden furniture, and more. Few products offer either the quality of results or the flexibility that you get from Prepdeck, and few make the task of removing old finishes or preparing new wood as quick and simple.

Ideal uses for Prepdeck

  • Prepdeck Stripper/Cleaner may be used on soft or hardwoods and thermo (burnt) wood.
  • It is ideal for garden decks, fences, cladding, log homes, and garden furniture.
  • Perfect for the removal of stains, finishes, and wood grade stamps.
  • Great for getting rid of mill glaze easily, thus allowing the wood to get the best finish possible.

Recommendations for use

Please note – when using Prepdeck you must neutralize the surface immediately with Net-trol. This prevents a reaction with the new coating to be applied.
