SUPERDECK® Semi-Transparent Stain Scores (1-10)
Appearance After Initial Stain Application: 6
– We used the Superdeck Stain in the redwood color on a newly built redwood porch in Northern California. The final appearance after drying was a sticky uneven finish on our porch. The stain did not penetrate very well into the wood even though the Superdeck cleaner and brightener was used to prep prior to application. Only one light coat was applied.
Preventing UV Graying at 2 Year Mark: 8
– 80% of the initial color was left after 2 years of exposure in full sun. The Superdeck did score fairly well here.
Wear/Tear and Peeling: 8
– The was no peeling of the Superdeck Semi-transparent stain but there was wearing in the high traffic areas. This porch is the entrance to the home and the Superdeck was completely worn from the stairs to the door.
Cost Per Square Foot: 7
– Superdeck Semi-transparent stain costs $40 a gallon. The 800 foot porch needed 5 gallons to cover. This included the deck and the railings.
Preventing Mold/Mildew/Algae: 6
– After 2 years of weathering, the Superdeck Semi-transparent stain had a significant amount of mildew spots growing in the finish. Containing linseed oil (known feeder for mold), the Superdeck seemed ineffective at preventing the mold even though it contains mildewcide.
Ease of Application: 7
– We applied the Superdeck Semi-transparent stain with a staining brush to the entire surface of the porch. The stain had issues with penetration into the wood and did not dry evenly. It took nearly 8 hours to apply the stain with two people.
Color Shifting (darkening) after 2 Years: 5
– Very disappointed with the Superdeck Semi-transparent stain turning a dark blackish color after two years. It seems that dirt sticks to the stain. There was a tree above the porch that may have contributed to this issue.
Difficulty of Reapplication: 6.5
– Unfortunately, the Superdeck Semi-transparent stain will need to be stripped and brightened prior to reapplication since the stain had turned a very dark color after the two years.
Overall Score SUPERDECK® Semi-Transparent Stain at 2 Year Period: 6.69
– We were not impressed with the Superdeck stain. Most disappointed with the application and overall appearance after 2 years. Wood stains should not turn a dark black color after 2 years of exposure. This is very unsightly and makes reapplication difficult.
