TWP Stain Tips for New Wood Decks in 2025
Preparing New Wood for TWP Stains
When applying TWP Wood Stains to new wood for the first time, following the correct preparation steps is crucial. New smooth wood or decking is not ready for staining before installation or immediately after. Always adhere to the TWP Wood Stain guidelines rather than relying on advice from a lumber yard or paint store, as they may not fully understand the prep requirements for optimal results.
TWP and New Smooth Decking or Exterior Wood
New smooth wood is not sufficiently absorbent for TWP Stains due to higher moisture content and the presence of “mill glaze.” Mill glaze is a waxy film that forms during the milling process when high-speed blades heat the wood, drawing out sap and moisture. As this cools and dries, it creates a coating that prevents TWP Stain from properly penetrating the wood grain.
Important Note:
- New Rough Sawn Wood/Fencing: Unlike smooth wood, new rough sawn vertical wood or fencing can be stained immediately after installation without waiting or extensive preparation, as it lacks mill glaze and is highly absorbent.
- Ensure the rough sawn wood is fully dry before staining. If it has aged or oxidized (turned gray), prep it using the Gemini Restore Kit before application. For newly installed rough sawn wood, one coat of stain is usually sufficient.
Proper preparation ensures your TWP stain delivers its intended durability and beauty, whether you’re working with smooth or rough sawn wood.
