I have used TWP on new wood with great success. However, now I am trying to restore an old and weathered pine deck. The wood is not rotted but does have some old ‘solid’ stain remaining on the wood. My questions are:
1) Can TWP be used effectively even though there is still some old stain on the wood?
2) If so, after the TWP has thoroughly dried, can another deck-resurfacing product be applied over it? Will deck-resurfacing products adhere to a TWP-prepared surface?
3) How dry does the old deck wood need to be before applying a TWP product?
1. No, all previous coatings must be removed before using the TWP.
2. No, you cannot apply any coating over the TWP, it will peel if you try this.
3. 48 hours of no rain or after any prep.

We just received 5 gallons of twp101 and will be using it on a western red cedar fence I’ll be building soon. The upper 4 feet of the fence will have horizontal louvers. The louvers angle at 45 degrees and are not-adjustable. I had planned on pre-staining the (rough cut) louver-slats so as to more easily cover all sides of the wood. Good idea or problematic working with this pre-stained wood?
Also, because I’ll be using postmaster posts, when building up the posts, some boards will be completely covering other boards. I just saw you mention that only exposed wood needs to be stained but wonder if that advice applies to my situation as well: wouldn’t 4-side staining help with repelling moisture, reduce warping, further slowing rot? I’m in Minnesota.
You only need to stain the exposed sides after install. Staining all sides can lead to issues (the wood may not be able to breathe) and does not provide more protection.
Just stain it all at the same time and only the exposed wood.
Thank you for your quick reply! OK, So I’ll stain a post after it’s assembled.
I’m not sure now what to do with the louvers. They are exposed to the elements on the 4 main faces. Can you explain further about the problem with sealing all sides? These rough-cut 5/8″ x 6″ x 5′ boards are in my garage, quite dry.
