Pick the right time
Stain on a dry day with mild temperatures and no rain in the forecast for a couple of days. New wood may need to weather for a few weeks to absorb stain well.
Avoid staining in direct hot sun, which can dry the product too quickly.
Clean and prep
Wash the wood with a gentle cleaner and a soft brush, rinse and let it dry fully. Sand rough spots and splinters. Tighten hardware and repair damage first.
Cover surfaces, plants and the ground nearby.
Choose a product
Choose a stain or sealer made for outdoor wood and suitable for play equipment. Semi-transparent stains show grain, solid stains hide it and clear sealers keep a natural look.
Read the label for dry time and cure time.
Apply it well
Work in sections along the grain with a brush, pad or sprayer. Do not let it pool. Wipe off excess. Pay attention to end grain and joints, which absorb more.
Apply a second coat if the product recommends it.
Let it cure
Let the finish dry and cure fully before kids use the set. This can take a few days. Check the can for the recommended time.
Plan to refresh every one to three years.
Common mistakes
Staining wet wood, applying too thick a coat, skipping the end grain, staining in hot sun or not letting the finish cure. Each one shortens the life of the finish.
Take your time and follow the label.
Choosing a color
Lighter semi-transparent stains show the grain and age gracefully. Darker colors hide imperfections but show scratches and fade faster in sun. Test on a hidden board first.
Accents such as roofs and slides can bring in color without staining the whole set.
Quick answers
Do I need to sand first?
Sanding rough spots helps, and removing loose old finish is important for good adhesion.
Can I stain a set that is already stained?
Often yes, if the old finish is sound and compatible. Test a small area first.
