Staining New Wood with TWP Decking StainsWhen applying TWP Wood Stains for the first time to new wood there will need to be proper steps taken. New smooth wood or decking is not ready to be pre-stained prior to installation or stained right after installation. It is best to follow the directions of the stain manufacturer when it comes to applying a coating to new wood for the first time, not the lumber yard or the paint store's as they do not understand the proper prep needed.

TWP and New Smooth Decking or Exterior Wood

It is important to understand that new smooth wood is not absorbent enough for the TWP Stains. New wood contains a higher moisture content and a "mill glaze". Mill Glaze is a waxy film that results from the fast turning blades that cuts the profile on a manufactured log. The high speed of the turning blades produces heat that draws sap and moisture out of the log. As it cools and dries, it creates a film or coating on the logs.  This will hinder the TWP's ability to penetrate into the wood grain.

Note: New Rough Sawn vertical wood/fencing can be stained right away with no wait and with no prep as it does have mill glaze and is very absorbent. Just make sure the wood is fully dry. If Rough sawn wood has aged or oxidized (grayed) then it will need to be prepped with Gemini Restore Kit. One coat for most instances of newly installed Rough Sawn wood.

How to Apply TWP Wet on WetTWP Stains are to be applied "Wet on Wet" when the wood is absorbent enough to handle more than 1 coat of the stain. This is typically for wood and decking that is older than 12 months and has been exposed to the elements. Applying the TWP "wet on wet" is similar to applying 1.5 coats of stain. The second coat covers twice as much square footage as the first coat.

Applying TWP "wet on wet" is very easy and not complicated once you understand the simple steps.

With newly installed treated lumber, it is necessary to wait an adequate period of time for the wood to season or dry out prior to staining it with TWP. New wood sometimes referred to as “green” wood, has a very high moisture content when it is new. Staining wood in this condition would trap moisture under the stain and potentially lead to mold, mildew, and wood decay issues. This can mean premature future costly repairs and replacement of the wood so it is best to wait. The seasoning time frame can be around 4-12 months give or take depending on the climate, weather and sun exposure.

To avoid having to wait months to stain your new wood you can use KDAT wood instead. KDAT (kiln dried after treatment) is wood that is dried in a kiln after it has been treated with the proper bug deterring chemicals. The wood is then put on the market and sold. It is slightly more expensive than regularly treated wood but it may be worth not having to wait as long to stain it. The wait time for staining new KDAT wood with TWP is about one month. This cuts down significantly on the wait time and may be the right option for you.
