What types of furniture can be finished with clay plaster?

Outdoor clay plaster is a natural, breathable exterior finish designed for walls and facades. It’s made from a blend of clay and minerals, creating a durable and weather-resistant coating that provides a soft, organic look while protecting exterior surfaces.

It can be applied to a range of rigid, stable substrates. For best results, the surface must be clean, dry, and free of movement. On certain substrates, a primer or reinforcing base coat may be recommended to ensure proper adhesion and durability.

Outdoor clay plaster is typically applied in two or three thin coats by hand or trowel. Each layer is allowed to dry fully before the next is added. The final surface can be smoothed or textured, depending on the desired finish.

Maintenance is minimal. Simply rinse gently with water or wipe with a soft brush to remove dust and debris. Avoid using high-pressure washers or abrasive cleaners.

When applied by a professional and maintained correctly, outdoor clay plaster can last years. Its natural durability, breathability, and repairability make it a long-lasting, sustainable alternative to conventional exterior coatings. Small surface imperfections can be easily repaired without the need for full reapplication.
