Flood CWF Oil Wood Stain Review
Flood CWF-UV 5 OIL is a high quality translucent, transparent and semi-transparent wood finish for exterior wood. It is a deep penetrating oil that is fortified with Flood’s Penetrol additive for maximum protection. Containing transparent oxides to protect from graying and ultraviolet damage.
Note: Flood CWF products have undergone numerous changes in the last 20 years. Flood back in its heyday was at the top of the stain world with its original oil-based formula. This formula is no longer available as the company has gone through numerous changes such as product reformulation (change from oil to water-based), name changes (Supreme Performance), and parent companies. Flood is currently owned by Akzo Nobel. It seems that Flood has gone back to its roots by reviving the CWF formulation that powered this company in the first place.
We only hope that the CWF is as good as it used to be in the early 1990’s.
Flood CWF Oil Stain Ratings (1-10)
Appearance After Initial Stain Application: 7
– The Flood CWF in the transparent cedar color had a nice golden color with a hint of orange. The cedar deck was highlighted with a rich color but the knots of the wood was very light, almost blond in color. There were a few shiny spots throughout the deck where the stain did not absorb very well.
Preventing UV Graying at 2 Year Mark: 7
– Flood CWF did okay at the two-year mark where about 70% of the original color remained on the wood. We were pleased but had hoped for better results.
Wear/Tear and Peeling: 8
– We noticed a small amount of wearing on the stairs after the two years. Most of the deck did not have any issues.
Cost Per Square Foot: 7
– On our cedar deck, we used 5 gallons of the Flood CWF-UV 5 OIL. The square foot coverage was much less than the manufacturer’s claims of 200 feet per gallon. About $.40 a foot.
Preventing Mold/Mildew/Algae: 7
– We had mold growing on about 30% of the deck floor near the house after two years. This area is shaded most of the time. The posts holding the deck had some green algae.
Ease of Application: 7
– The first coat of applied was a little difficult to get on evenly. We used a stain sprayer for the railings and pad applicator for the flooring. We applied the railings first and had some running drips that we back brushed right away. The floor was uneven after the first coat, evened out better after the second coat but had some shiny spots.
Color Shifting (darkening) after 2 Years: 7
– Not sure if the stains had issues darkening on the dirt from the trees but either way the Flood CWF-UV 5 OIL did darken in color slightly after two years. Only on the flooring and horizontals areas. No issues with the vertical sides and rails.
Difficulty of Reapplication: 7
– Since the stain darkened slightly we would suggest a deep cleaning or light stripping followed but a wood brightener. Fortunately, this would be an easy strip if needed. No sanding would be required.
Overall Score Flood CWF Oil at 2 Year Period: 7.125
– The Flood CWF-UV 5 OIL is an average stain. Nowhere close to the original Flood CWF in the 90’s. Overall we were disappointed and we always score stains harder when they offer warranties that are not possible to attain. It is unfortunate that many manufacturers need to make these impossible claims just to achieve sales. The odd thing is the Flood CWF is better then it’s now sister stain Sikkens. Even though Sikkens costs 50% more. Both are manufactured by Akzo Nobel.
