Considerations in Best Stain for Swing Set
If you’ve recently acquired a swing set/ play-set and assembled it for the kids to start to enjoy their backyard fun and games.
But the wooden swing set, like decks and the house, will still lose their vitality and brightness if they’re not properly maintained – but you can also get rid of the spray paint smell.
1. Install it on a Level Ground
First, you must install the swing set on a level and soft ground surface. This is mainly because the play-set will be heavy after installation and may dig deep into the earth.
So, don’t install the set on a loose surface such as shredded rubber, chips, mulch, pea gravel, or sand.
Therefore, installing the set on a level and soft ground will prevent it from moving around due to animals, wind, kicking, or scuffing. Further, when the field is patchy or uneven – you’ll require to rake it to achieve a smooth texture.

2. Undertake Regular Maintenance
Considering your locality, it may be that the swing season is coming up fast, and the children will actively be on the wooden swing sets.
Thus, you’ll require to inspect the play-sets at the start of the start and undertake appropriate maintenance.
However, for colder localities – having snow and frosts – you’ll require to install the play-sets in an indoor space or build a shelter around the swing sets.
Alternatively, you may use a plastic swing set, which won’t affect the cold weather’s adverse effects.
For example, conduct the annual inspection at the start of spring, including repairing and replacing broken parts and painting or staining the wooden sections.
Ensure that the parts have no crevices or cracks before reinstalling them on your swing sets.
3. Stain the Play-sets
Equally important is that you must stain the play-set to provide them with a fresh look to protect the wood surfaces from mildew while ensuring that you wash dirt and clean any dust.
Further, use moderate pressure for the water blusters – this will ensure you won’t damage the swing sets. After cleaning the wood surfaces, allow the wood to dry for about 25 hours before sealing and staining them.
If you’re thinking between water-based or oil-based stains, use appropriate for the decks – particularly for the cedar color.
Conclusion
Like BBQ grills must be put away in winter, swing sets must be stained & sealed. Furniture stains offer a tint that’ll restore the color, but the deck sealer for treated wood leaves wood clear.
You’ll require to stain or seal the wood in spring o protect the wood from the harsh sun’s summer effects. Further, you can stain or seal the swing set sooner or later when it’s new.
