Now that spring is in the air; our attention can turn to the outside living spaces of our homes. Whether you have a small outdoor area or a large garden, it is likely that you have some exterior wood that needs maintaining after a hard winter. Now is the time to get out that sprayer, brush or roller and bring the natural beauty back to your exterior woodwork.

For some, this can be a daunting process, and the DIY store is filled with preservatives, stains, sealers, and all-in-one products that can make our heads spin. Fear not, however, as there are some great products out there to minimize the pain and maximize the beauty of your woodwork.

What Are Wood Sealers and Stains?

A sealer is a product designed specifically to seal the wood to prevent water absorption. This protects it against rot and fungus, as well as warping and discoloration. Sealants can be transparent or colored.

A stain is designed to color the woodwork by penetrating the grain. This can be as strong or as subtle as you choose. A stain will not necessarily preserve or protect the wood against the elements.

Some products combine stains and sealants in a handy all-in-one product, and there are ones designed for application to dry, damp or new wooden items around your home.
