to avoid this if you do store plywood against a wall is to secure it flat against the wall with bungee cords, rope or by some other means so it can't sag.

Liquid Storage: Paints, Stains, Finishes and Glue

The many liquid materials that wood-shops accumulate present their own storage and handling challenges. While the containers take up far less room than does lumber, what's inside all those bottles and cans can be a good deal more finicky. In some cases, liquids can present safety hazards if not handled carefully.

Finishes come in a wide variety, from water-based latex paints to lacquers and shellacs made with volatile solvents. In general, water-based finishes must be protected from freezing temperatures if they are to remain useful. If you work in an unheated shop in a cold climate, these materials will have to be stored inside when it gets cold.

Solvent-based finishes are not as temperature sensitive, but they are usually more flammable and the powerful solvents they contain can be a fire or explosive hazard in an enclosed space. Companies that specialize in safety equipment sell metal cabinets made specifically for hazardous liquids - it's a good investment if you have a lot of finish on hand and want to protect your shop from the possibility of fire.

Finishes also don't last forever. Polymerizing oils, varnishes and similar finishes have a way of turning into thick gunk over time. It's a good practice to mark the cans with the date of purchase, or the date on which they were mixed if you make your own brew, so that you know when they should be retired. (When the time comes, don't toss them out the back door or dump them down the drain. Contact your local municipal offices or state environmental office for advice on getting rid of expired finishes.)

Try to store finishes out of direct sunlight and away from sources of heat.

Some materials common to woodworking shops are hazardous if not handled properly. Rags soaked in oil finish can ignite spontaneously if they are not spread out to dry or immersed in a pail of water.

A locker specifically designed for flammable materials is a good investment. Its double-wall construction would help prevent the spread of fire.

They will last longer.

Glue is another material that can be sensitive to time, sunlight and temperature. Yellow and white polyvinyl acetate glues (Titebond and Elmer's Carpenter's Glue, for example) as well as liquid hide

glues are happier if they are not allowed to freeze. Even if still in a liquid state, these glues should not be used if they are too cold because the bond will not be reliable - check the label for the specifics. If you have a heated space for
