Clean the surface with a brush to remove excess debris. Over time cement ornaments that have been neglected have an accumulation of mold or plant buildup. Mold on concrete thrives in damp and moist conditions. 

The good news is that mold isn’t lethal, but understanding the conditions that allow the organism to survive and exist is essential. Clean the surface with a soft-bristled bush. Using a combination of soap water with a brush will allow you to carefully inspect the art piece for vulnerable joints and crevices that require your attention to strengthen the cement ornament. 

Be careful if you decide to use an air hose or power wash, as the art pieces that have not been cleaned for a very long time may crack and lead to significant repairs down the road. 

Once the cleaning is completed, have the art piece dry and ready for the next step. It’s advised to move the concrete art to a less moist and open area with lots of sunshine. Ensure the surface is completely dry to avoid mold and mildew regrowth.

Concrete is known for wicking water when left on most ground surfaces relocating the art piece, and monitoring your garden surface for dampness. Avoid your garden from pooling water by improving the drainage and avoid over watering your garden plants.

Repair the crack in your Concrete Ornament.

  The changing temperature in the winter does cause water to change state from solid to liquid. The presence of water on cracks on statues and birdbaths in the winter experiences contractions and expansion. The freeze and thaw process causes pressure causing the cracks to expand.

The cracks can lead to significant fragments of the art piece falling off. Prolonged exposure to the harsh winter and negligence from the owner can lead to the loss of beautiful concrete art.  

Cracks can be identified during the warm summer months. Inspect the surface for any small cracks and fractures. You can fill the cracks with epoxy. 

Epoxy concrete is a flexible material for filling cracks and restoring surface durability. The application of epoxy can be made by both experienced and newbies. Following the manufacturer’s instructions is the best practice before your first application.

Fix the epoxy as soon as the crack appears. Applying the epoxy when it’s smaller is recommended; once it becomes larger, you can use mortar.

Apply a waterproof Concrete Seal.

 Unfortunately, the development of concrete art surfaces is a certainty. Concrete surfaces are known for their durability and versatility; however, they are susceptible to cracks and fractures. Outdoor concrete art experience harsh temperature from cold and humid weather that can cause the surface to deteriorate over time.

An early intervention to preserve and protect the surface is the application of a waterproof concrete sealer. Early application during the creation phase of the concrete structure will safeguard the surface from stress and the early development of cracks.

Before applying the concrete sealer, ensure the surface is free from debris and dirt. For new concrete art pieces, you need at least 30 days before application to ensure that the surface has fully cured. 

Read the manufactures instruction before applying the concrete sealer. Most sealers can be applied using a brush or a roller. Apply the sealer thoroughly to ensure the whole surface is covered evenly. The porous nature of concrete requires more sealant to protect the surface adequately. 

Let the surface rest for 10 minutes, and a second application is recommended.

Make sure to Cover and Store your Statue in Winter Months.

Extreme temperatures tend to affect the structure adversely. Concrete can expand and contract with environmental changes. Each climatic conditions have its way of reducing the adverse effect of the weather.

In the winter, consider covering up your statuses and garden art that tend to collect or retain water. For statues and art pieces that are too heavy or secured in place, the only option is to cover them with a waterproof tarp or cover. 

For statues that can be relocated, move the art pieces to a dry indoor away from the harsh winter weather. The indoor area conditions can be controlled, reducing the possibility of your concrete figures being adversely affected.

Be careful during the relocation process from damaging or dropping your concrete art. You don’t want to end up with a more significant problem fixing damages that require extensive repairs. The method of moving your statues needs to be planned out carefully. 

Pay special attention to intricate and delicate parts that may come off during the statue’s movement.
