Is Painting My Shed Interior Worth the Work? – What to Know

Spread the love

After constructing a good shed with the exterior work all touched up and completed, you will probably be asking yourself if it is a good idea to detail the interior of it. The answer depends on the entire purpose you built the shed for. If it a storage shed for tools and garden equipment and furniture, then perhaps the extra costs of paints are not quite justified. But if you are talking about a shed that doubles as an extra living space that will often be occupied, it is a wise idea to do some paintwork inside. 

Ultimately, the choice is yours, but from us here at Shed Mechanics, here are a few things to consider when deciding on interior detailing: 

The Benefits of Painting Shed Interiors

Depending on the blueprint you used for the build, some sheds have limited or even no sources of light. If you find that your project has no windows, having a coat of nice, bright white paints on the walls will give it extra light when coupled with a good lightbulb setup. If you find that white is too bland or plain for you, pastel colors and light gray paints work just fine, and may even give it an extra touch. 

Asides from brightening up the ambiance and atmosphere of the shed, paint coatings are able to eliminate construction stains and prevent insect damage and leaks, as well as mold growth. This way, the wood boards and other materials in the shed will last even longer because of the protective layer that good quality paint provides. 

Painting a New Shed Versus an Older One

The best time to paint is as soon as the building is finished, so that the raw materials used are not exposed directly to the elements for prolonged periods, causing deterioration. It is important to analyze build for cracks or holes, which can then be filled in with paintable caulk to avoid leaks. Then, primer must be used so that the main paint mix will stick to the surface. Doing it off the bat makes future maintenance less of a headache, so consider the choices ASAP.

Older shed units may be more complicated, as time has taken its toll on the freshness of materials. It also takes more work due to the need to empty the stored items, as well as clean up all dust and debris that have occurred throughout the seasons. Spray washers can assist in a deep clean, but it is still a lot of work to be done depending on the size of the shed. Once cleaned out, it is best to replace rotting parts, patch up holes and gaps, and then proceed to prime the surfaces for painting. 

Be Aware of Weather Conditions That May Affect Paint Drying

Temperature and humidity play a part in the interior detailing process, as certain temperatures allow the paints to dry quicker and stick more effectively. For example, oil-based paints are applied best around 40 to 90-degree Fahrenheit, while latex paints dry well at around 50 to 85-degrees Fahrenheit. Paints naturally dry quicker in heat, so lower temperatures will mess with the drying procedure. Humidity should range between 40% and 70% for the best adherence of the paint. High humidity may cause dampness in wood, which causes paint to flake easier. 

Try Painting the Floor of Your Shed

Again, this option depends on what you intend to use the new space for. There are many benefits to it, such extra protection against wood deterioration and splinters, and allow the entire floor to match the color pallet of the walls. Using specialized paint for floors, allow several days for it to completely dry before placing any items within the shed. This is a more taxing project, but it can definitely add aesthetic value to your new room. 


Painting the interior of a shed is quite taxing, but the payoffs are great if done correctly. Whether it is to be turned into a storage area or your next mancave or guesthouse, having a shed is an invaluable addition to your home area.
