When staining a deck, see that the surface is clean, or use a deck cleaner to clean the surface. Old decks might contain mildew, algae or mold, hence it is good to use wood brightener. Use sanding sponges or sandpaper to clean the surface of mill-glazed wood. Leave the surface to dry from two to three days before staining for good results. Choose the best quality stain so that the life expectancy of your deck will increase. You can use semi-transparent deck stains to show through the wood’s grain. If you want the surface to be opaque, you can use solid deck stains that come in different colors.

It is preferable to apply stain when the atmospheric temperature is between 50 degrees Fahrenheit and 90 degrees Fahrenheit. Applying stain during dew or frost or wet weather may lead to bad results. Allow it to dry for two to three days and avoid drying under direct sunlight.

A stain brush is advisable for spraying as it has greater penetration into the wood surface. Don’t apply too much stain. The exposed ends should be coated many times so all the wood pores are inundated. Sometimes over-application may also result in a surface that is waxy, sticky, or slick. Follow the manufacturer's instructions, and when you have doubt it is better to ask the paint specialists.

Allow the stain to dry for 12 to 24 hours, depending on the temperature and humidity. There is no need to use varnish or polyurethane, as they do not hold up against sunlight. Wear safety glasses and rubber gloves for protection.

For all prescreened decks, porches, gazebos and play equipment, contractors can help you solve your queries.

Wood surfaces that are stained should be retreated every 2-3 years or earlier depending on weather exposure. Every year a close inspection of treated surfaces should be done.
