Armstrong Clark Semi-Solid Wood Stain Review

Here at DeckStainHelp.com, we take pride in the fact that we have become the Internet’s number one reference for all things exterior wood and deck restoration related. Today we are reviewing the Armstrong Clark in the Semi-Solid Colors. We have found that the higher the solid content, the longer the UV protection when using the Armstrong Clark Stains.

Newer for Armstrong Clark is the Espresso Semi-Solid color, a rich deep brown tone that promises excellent UV resistance.

Armstrong Clark Semi-Solid Stains are a highly regarded oil-based stain formulated with 5 generations of stain industry experience. Armstrong Clark Semi-Solid Stains are available in 5 colors: Mountain Cedar, Woodland Brown, Oxford Brown, Sequoia, and Espresso.

Armstrong Clark Deck Stains are uniquely blended with drying and non-drying oils that isolate from each other during application. The non-drying oils penetrate the wood fibers and help rejuvenate and condition lost natural oils while the drying oils cure on the surface to lock in the conditioning oils and form a barrier of weather protection at the surface.

Preventing UV Graying at 2 Year Mark: 8

– Upon our 2-year inspection, Armstrong Clark Semi-Solid Wood Deck Stain produced above-average UV resistance. Using the Semi-Solid Mountain Cedar color, we projected better-than-average UV shielding, and it did not disappoint. The Armstrong semi-solid colors have shown to have better UV protection than their transparent and semi-transparent colors.

Wear/Tear and Peeling: 9

– No peeling was detected at the 2-year point. There was a slight wearing on the high-traffic areas, around the furniture, and on the stairs.

Cost Per Square Foot: 9

– Armstrong Clark Semi-Solid Deck Stain can be purchased for about $45.99 per gallon. In our test experience, Armstrong Clark Semi-Solids had one of the best spread rates of any stain. We used a total of 4 gallons on our 800 square foot deck and applied in one coat.

Preventing Mold/Mildew/Algae: 8

– At 2 years we noticed some slight mold growth on top of the Armstrong Clark Semi-Solid stain in some shaded areas. We did not detect any mildew spores within the stain as the mildew spores could be wiped away using a wet towel.

Ease of Application: 9

– The Armstrong Clark Semi-Solid Deck Stain was easy to apply. The stain did not dry too quickly and applied even in those conditions, avoiding potential issues with Applying a Deck Stain in Full Sun. We used stain pads and brushes to apply to the deck. Took about 2-3 hours to apply with a team of 2 workers. One Note, it did take the Armstrong Clark Semi-Solid a few days to fully cure.

Color Shifting (darkening) after 2 Years: 8.5

– Our 2-year test of Armstrong Clark Semi-Solid Mountain Cedar color did show signs of slight darkening from its original color. We figured this was likely due to a higher solid content of the formula. The AC is over 70% solids, containing both linseed and paraffin oils.

Difficulty of Reapplication: 8.5

– Because Armstrong Clark Wood Deck Stains penetrate well and did not overly darken, it would be easy to re-coat. A simple cleaning with a wood deck cleaner to remove dirt, grime, and mold spores would be plenty sufficient prior to reapplying.

Overall Score Armstrong Clark Semi-Solid Stain at 2-Year Period: 8.5

– Armstrong Clark Semi-Solid Mountain Cedar held up well at our 2-year test mark. Easy to apply and terrific coverage rates, raise Armstrong Clark to a high level. No peeling and only a slight darkening color shift were more than acceptable. Easy to maintain and prep prior to re-coating. Armstrong Clark is definitely one of our top choices for a professional durable finish that lasts and is easy to work with in the future.
