Almost any surface can be used for decoupage, but different surfaces will require different treatment. Traditionally, wooden objects are used, especially furniture. But any smooth surface can be decoupaged. Trays, boxes, and picture frames are ideal for the beginner. Before you begin, make sure that the item is clean and free from dust or flaking paint. Unfinished wood must be painted, stained, or sealed before decoupaging. If the item needs to be painted, use the appropriate paint and let it dry for twenty-four hours. It will also need to be lightly sanded so that the glue adheres better. We’ll discuss preparing surfaces for decoupage in further detail in the section on techniques.

Wood
New wood is easily available and it requires little preparation. Most suppliers have a large range of items. Varnished wood needs a light sanding before use to help the water based glues and varnishes to adhere properly. Old wood may take more preparation, but has a lot of character.

Metal
Old metal items also often have a lot of character. Local secondhand shops can be a great source.

Galvanized Steel
Galvanized steel is increasing in popularity and can now be obtained from craft shops. These items are delicate in appearance with intricate, scalloped lines. Some preparation is required to ensure proper adhesion. These items are extremely delicate and will chip if used roughly and regularly and so should be kept for decorative purposes. Try not to get water on the steel, especially if you are using it as a flower holder. Use another container inside the steel item.

Ceramics
Unglazed, bisque-fired ceramics are best for decoupage and come in a wide variety of shapes. These items are purely decorative. Hot food shouldn’t be served in them, only use them as containers for dry items such as pot pourri or nuts. Wipe clean with a damp cloth, but don’t immerse in water or put in the dishwasher.

Porcelain
Once complete, you can use the item for what it was originally intended for. Serviettes are good to use as they are extremely thin and melt into the porcelain. Try to keep to lighter colors in porcelain, as serviettes will disappear altogether into a darker background.

Enamel
Enamel needs a light sanding and a coat of steel primer followed by a coat of universal undercoat. It can then be treated the same as porcelain.

Glass
Glass needs a through clean with warm soapy water and a good rinse before being used. These items are usually for decorative use, but if you want to use your glass item, try using serviettes and porcelain medium on an ovenproof glass item that can be heated. Baking your item dry will seal and harden your artwork, making it more useable. Don’t immerse the item in water.

Candles
It’s best to use thicker candles as a thin one will burn too quickly, as well as being difficult to work with. They tend to burn down in the center, leaving a safe zone on the edge.

Soap
Any soap can be decoupaged, provided it isn’t too oily. The soap can be used although the picture will eventually come off. Decoupaged soap makes great gifts.

Once you’ve found an item you want to decoupage onto, you need to make sure that it’s free from dust and dirt. The surface may need sealing and you may need to paint the item first. Some surfaces will need sanding first. Don’t begin to decoupage until the item is clean and dry.

With the amount of work you’ve put in, you’ll want to keep your piece beautiful. Waxing periodically provides good protection. Wipe all spills immediately with a soft cloth. Don’t use furniture polish as it can cause a buildup and over time ruin the surface. A damp sponge or cloth works well for cleaning. Don’t place a piece of decoupage in direct sunlight, as it will fade over time.

Remember that varnish takes about a year to fully cure. Don’t put heavy objects on a flat decoupaged surface for at least a year or they will cause dents in the surface. Once the surface has hardened, this isn’t so important. Varnish dries from the top down, so although it may feel hard and dry on the surface it can still be soft further down.

Any small chips that occur over time should be repaired as soon as possible. If the varnish is chipped but the decoupage has no damage, sand the surface. Apply a drop of varnish and allow to dry. Repeat until the chip is filled. Decoupage is not hard to care for and with proper care it will last forever.
