Composed of natural and synthetic oils, TWP 100 Series will provide ample protection from snow, rain, and UV radiation.

TWP 100 Series has been rated #1 by Consumer magazine.

TWP Stain – 100 Series Rating

TWP 100 Series Wood Deck Stain Scores (1-10)

Appearance After Initial Stain Application: 8.5

– We tested the 101 Cedartone color for the pool deck. The semi-transparent color was a traditional cedar color, slightly orange/yellow. The stain had no issues penetrating into the wood completely and did not mask the wood grain.

Preventing UV Graying at 2 Year Mark: 8

– The TWP 100 Stain retained 80% of the original color after 2 years of weathering.

Wear/Tear and Peeling: 8.5

– TWP 100 exhibited zero peeling of the stain after 2 years. Slight wearing around the stairs where the wood butted up to the pool. This area was slightly more faded as well. Possibly from the chlorine in the pool.

TWP 100 Series

Cost Per Square Foot: 9

– We paid $139.99 for the 5-gallon pail of TWP 101 Stain. We used all 5 gallons for the 800-foot pool deck. We applied two coats to the wood. The cost to stain with TWP 100 Series was $.18 per foot for 2 coats of stain.

Preventing Mold/Mildew/Algae: 9

– TWP offers the best resistance to mold and mildew for an oil-based wood preservative. No mold, mildew or algae spores were present on the wood decking.

Ease of Application: 9.5

– TWP is easily applied. We applied two coats to the flooring using an 18″ wide stain applicator. The first coat took us about 30 minutes to cover 800 feet. The second coat took only 20 minutes as the TWP 100 applied at a better spread rate. Overall the 800 square feet were covered in under an hour and applied evenly with no puddling.

Color Shifting (darkening) after 2 Years: 9

– TWP 100 lightens in color after 2 years. No darkening from UV or mold.

The Difficulty of Reapplication: 9

– TWP 100 Pro Series offers deep penetration with no darkening of the stain. Reapplication will be easy without the need for stripping off the two-year-old stain. Cleaning to remove some dirt and grime would be enough to prep for another coat.

Overall Score TWP 100 Series at 2 Year Period: 8.81

– TWP for good reason gets one of our top overall scores. It is too bad that this product is not available in all 50 states but the TWP 1500 Series performed nearly the same in our test results and can be obtained in all states. If you are looking for a great stain that is economical as well, then the TWP 100 Series should be considered.

I did a reapply of twp on cedar siding exposed to severe weather conditions in Florida after the cleaning process 2 coats on problem areas and one coat on less exposed areas it has some shinny spot where it didn’t penetrate the wood as much wouldn’t it be better to leave those areas instead of wiping it of with the mineral spirits to keep the product on to protect the wood better in this environment?

Hi. We live in Georgia and trying to decide what to do about a new porch which faces South with a lot of sun (picture included).

We originally thought we would paint railings white and stain the cedar ceiling, corbels and gable. Now that we see the cedar railing, I think I’ve changed my mind as the wood itself is beautiful.

TWP 200 has been recommended by the contractor; however, he did not mention that the wood might need to age. Some of the wood seems rough and some smooth.

Couple of questions:
Would you recommend TWP 200 Butternut (as the door is stained a dark walnut) or prefer a TWP 100 or even an Armstrong product?

Would you still recommend to allow it all to age 4 – 12 months before staining?

Is there anything else I might be missing while considering staining everything as it pertains to direct sunlight?

Thank you in advance!

Is there any advantage in using 1500 TWP over 100 series for new Cedar Fence 6 mos. old?

Any thoughts on how twp 100 or 1500 will work on redwood? Testing was performed on pine.

5 years ago

I just re-coated after 3 years in MN using TWP100; almost 2000 ft2 of redwood decking. I used Wolman Deck & Fence Brightener Wood Cleaner and Coating Prep and power washed off before the re-coat (3 days drying) using a 40 degree nozzle (white). The reason using the Wolman product was to deeply clean/brighten the areas under roof cover, which were in great shape and I wanted the whole deck surface consistent in stain appearance. I just needed to clean some areas with mineral spirits after staining to remove the shinning stain where it didn’t soak in under the areas of roof cover where the original coat was still good.

The decking looks like the original coat after the re-coat. I love TWP100 and the Wolman (no sodium hypochlorite) made the cleaned decking look new. 2022 will be my next re-coat.

My re-coat was one applied coat using a deck staining pad and long pole to back brush where the stain wouldn’t completely soak in.
