Over the past year we have numerous questions asked on the site but none was asked more then “What stain or prep is needed for my new deck”? There seems to be an incorrect opinion among homeworkers that is is okay to stain new wood right away or even before the deck is installed. This is incorrect for most wood types and stain brands.
In this article we will cover the required prep and waiting period needed before applying a stain for the first time.
New Smooth Decking
New smooth decking boards are not porous enough for most stains to be able to penetrate properly. This is mainly due to:
Most wood stains when applied to new wood will have a very difficult time of penetration into the wood cells. This will result in an uneven application and premature stain failure by quickly fading or peeling. Remember, the better the stain soaks into the wood, the longer the life of the stain.
How To Prep for New Smooth Wood:
Once you get through the first couple of years, your deck stain will perform much better as the wood will allow more stain and a deeper penetration into the wood.
TIP: Do not sand new wood. This will smooth the wood even more reducing the stain’s ability to penetrate into the wood.
Rough or Rough sawn Wood
Rough sawn wood is not used for horizontal decking surface but rather verticals such as fencing, wood siding, etc. This side of the wood does not have a mill glaze and is very absorbent. As long as the wood has a low moisture content, it can be stained right away.
Stain Brands for New Wood
In our opinion certain brands of stains will work better on new wood. Through the years we have tried numerous stains on new wood and we have found that stains that contain paraffin (non drying oil) will penetrate into new wood better, even coverage, and can applied sooner.
We would suggest one of these 2 brands for new wood if you do not want to want 3-12 months to allow the wood to weather.
Armstrong Clark Wood Stain – Waiting period of 2-3 months
Timber Oil Brand – Waiting period of about 1 month or less
If choosing either brand, you will still need to prep the wood to remove mill glaze with cleaning and brightening.
