PPG Timeless Advanced Stain + Sealant Review
The PPG Timeless Deck Stain was introduced in 2017 into Home Depot. The product is actually the exact same thing as the Olympic ELITE Advanced Stain + Sealant in One (Lowes), just relabeled for Home Depot use. The review below is a repeat of our testings of the Olympic Elite version since it is the same stain.
PPG Timeless Advanced Stain + Sealant in One is a deck and wood stain that is ideal for bringing the rich look of interior wood to exterior wood surfaces such as decks, doors, furniture, and trim. Delivering more pronounced color while still enabling wood grain and texture to show, it provides luxurious appeal with a beautiful satin sheen finish. Formulated with both stain and sealant combined, this protective coating offers lasting defense against UV damage, mold, mildew, warping, cracking, and more, helping retain your wood’s natural beauty over time.
This is for the 550 VOC version that is an oil-based stain. They also carry a 250 VOC version and a water-based version.
PPG Timeless Stain + Sealant in One Stain Scores (1-10)
Appearance After Initial Stain Application: 6
– PPG Timeless Stain is an oil-based stain + sealer in one. We used the Chestnut Brown color. The appearance of the final stain finish was a brown color that did not seem to enhance the beauty of the wood as well as we had expected. However, the PPG Timeless Wood Stain did penetrate the wood fairly well and did not form a film on top.
Preventing UV Graying at 2 Year Mark: 7
–At the 2-year test mark, PPG Timeless did hold up pretty decent with an estimated 70% color retention. Some fading and graying were noticed in traffic areas.
Wear/Tear and Peeling: 6
–As mentioned the PPG Timeless Wood Stain did show signs of fading but no peeling. Most of the fading and wearing was on the horizontal surface like the tops of the handrails and deck flooring. There were almost bare areas with no stain left in the high traffic sections of the deck.
Cost Per Square Foot: 6
– It took 4 gallons total of PPG Timeless Deck Stain to coat the entire 600 square foot deck. The manufacturer claims 250-350 square feet per gallon but we experienced closer to 150-200 feet per gallon.
Preventing Mold/Mildew/Algae: 7.5
– PPG Timeless Deck Stain plus Sealer provided an average mildew-resistant coating and did an okay job at preventing fungal growth.
Ease of Application: 7.5
– The PPG Timeless Stain was average to apply. We did a one-coat application using a stain pad and did not get great coverage. We did not notice any overlap marks when finished.
Color Shifting (darkening) after 2 Years: 7
– At the 2-year mark, we did notice some darkening due to mildew but the PPG Timeless Wood Stain did lighten up on 90% of the deck.
The Difficulty of Reapplication: 7
– We did have to strip the old stain off due to bare wood and graying showing in high traffic areas and lightening of the stain in other areas.
Overall Score PPG Timeless Stain + Sealant in One at 2 Year Period: 7.0
– The PPG Timeless Stain + Sealant was an average score overall. The stain did hold up fairly well except in high traffic areas and some mildew was present. We were not overly happy with the coverage rates and will have to strip the stain off prior to recoating to remove the mildew.
