Note: This review is for the Olympic Maximum Stain + Sealant in One. This is their newer water based version. For the Oil Based review see: Olympic Maximum Stain Review
OLYMPIC MAXIMUM Deck, Fence & Siding Semi-Transparent Stain provides a subtle color that allows wood’s natural grain and texture to show through. Core-shell hybrid resin technology provides deep stain penetration, waterproofing, and UV defense to strengthen, protect and condition wood fibers, ensuring the wood’s natural beauty lasts.
Recommended for use on properly prepared exterior wood, including decks, fences, siding, railings, outdoor furniture, and other wood surfaces.
Olympic Maximum Stain + Sealant in One Stain Scores (1-10)
Appearance After Initial Stain Application: 6
– The Olympic Maximum Stain + Sealant in One is a water based acrylic oil hybrid. What that really means is that it is a waterborne stain. This stain applies like the majority of water-based stains in that it is a film-forming stain the does not penetrate into the wood deeply. The appearance of the Cedar natural tone on the deck was a mild orange color. We applied evenly but the final look was uneven as some of the stain dried into the wood and some did not.
Preventing UV Graying at 2 Year Mark: 8
– After 2 years the Olympic Maximum in the water-based version did a fairly decent job with only about 30% fading
Wear/Tear and Peeling: 5
– This stain had worn about 50% on the surface and handrails. Not a very good showing here.
Cost Per Square Foot: 6
– We used 10 gallons to cover the 800 square foot deck and railings at a cost of $.43 a foot. Coverage per gallon was closer to 150 sq. feet per gallon
Preventing Mold/Mildew/Algae: 9
– Olympic Maximum Stain + Sealant is a water-based stain that did an excellent job and preventing mold and algae growth. This is typical of most water-based stains.
Ease of Application: 6
– Average to apply. We applied 1 thin coat as the manufacturer suggests. Coverage was poor and not even close to the specs. Application with a stain pad did cause some overlapping.
Color Shifting (darkening) after 2 Years: 9
– The OLYMPIC® MAXIMUM lightens in color instead of darkening.
Difficulty of Reapplication: 5
– Since the stain had worn unevenly we needed to strip off the rest and start over. This proved slightly difficult but the old stain did remove after a couple of attempts with the stain remover
Overall Score Olympic Maximum Stain + Sealant in One at 2 Year Period: 6.75
– The Olympic Maximum has moved away from oil-based to the water-based stains and like many other brands, the performance has gone downhill. If you can still find the oil based versions in your local Lowes or Sears, then consider yourself lucky. If not, there are many better stains out there.
Important Note: OLYMPIC® MAXIMUM claims a 6 years warranty for decks. Warranties that claim ridiculous amounts of 5, 6, 7 years for exterior wood are using this for marketing. Do not believe it these false advertisements.
