Discover our range of clay plaster for breathable internal walls and ceilings, designed for natural building, renovation and healthy interior spaces. At Roundtower Lime, our clay plaster range includes practical base coats, fine finishing plasters and decorative clay finishes, giving you everything needed to create warm, natural and vapour-open interiors.
Clay plaster is one of the most effective natural materials for improving internal comfort. It helps regulate humidity, supports good indoor air quality and creates soft, characterful surfaces that suit both traditional and contemporary spaces. Whether you are building up uneven backgrounds, finishing a clay board system or creating a decorative feature wall, clay plaster offers a beautiful and breathable alternative to conventional internal finishes.
Our range includes coarse clay plasters for backing coats and levelling work, fine clay plasters for smoother finishing layers, and clay decorative plaster for natural textured surfaces with depth and visual interest. We also supply complementary products such as Clay Adhesive & Reinforcement Plaster for embedding mesh, reinforcing boards and preparing surfaces for final clay finishes.
Clay plaster is ideal for use over suitable internal backgrounds such as masonry, wood fibre boards, clay building boards, reed mats and other breathable substrates. It is especially well suited to heritage buildings, natural homes, low-energy construction and projects where vapour-open materials are important.
From practical base coats through to refined decorative finishes, our clay plaster range makes it easier to create complete internal wall systems that are natural, breathable and visually distinctive.
