Update 2018 for Why Deck Stain Cannot be Shiny
We here at DeckStainHelp.com are proud to be the internet’s number one reference for all things wood deck restoration related. As before, we do not recommend the use of polyurethane stains on outdoor decks. We always appreciate your input and questions, so feel free to leave a comment below.
Unlike some wood stain finishes on hardwood floors that have a reflective or shiny finish, most exterior deck stains are not meant to be shiny. A deck stain works best when it is applied to a clean wood surface. This allows the deck stain to penetrate deep into the wood pores to ensure a solid wall of protection against sun and water damage. The amount of deck stain that is applied depends on different factors like wood age, condition, and porosity. Not all wood surfaces will absorb the same amount of deck stain when they are being refinished.
It is important to follow the manufacturer’s recommendations for applying a deck stain. Some deck stains will be sufficient with one coat while others may be applied in several coats for maximum protection. A deck stain that has cured or dried to a shiny finish most likely indicates an over application problem. When deck stain is applied correctly it penetrates the wood giving it a natural finish. Most deck stains can enhance the natural beauty of the wood even without a shiny finish.
When deck stain is over applied, the excess stain that was not absorbed by the wood remains on top the surface and dries to a crusty shiny finish. This problem results in peeling, flaking, cracking and an overall decrease in appearance. You might think more is better when it comes to applying deck stain but that is not the case. A shiny finish can lead to premature failure of the deck stain product.
To avoid over-applying deck stain so it does not turn out shiny and end up failing prematurely work in small areas at a time. It is best to coat one whole board from end to end and wait several minutes for the deck stain to penetrate the wood. Try not to apply stain on a hot day or in direct sunlight as this can alter the absorption rate and dry time. Once the stain has had time to absorb, wipe away or back brush any excess stain puddles or runs before coating the next board. Applying only as much deck stain as the wood can absorb will result in a better finish ensuring the deck stain is not shiny when it cures. This will give you a longer lasting finish.
