Whether polished to a mirror-smooth elegance or applied with expressive, tactile patterns, Clay Stucco transforms surfaces into dynamic focal points that breathe with the interior.
UKU Clay Marmorino is a decorative finishing plaster that replicates the natural, satin-like elegance of stone and marble. Applied in thin, refined layers, it allows for the creation of sophisticated surfaces ranging from a soft matte to a luminous satin-gloss finish.
CLAY DECORATIVE PUTTY
UKU Clay Decorative Putty creates a seamless, matte surface that serves as a versatile canvas for various textures and artistic patterns. Beyond its stand-alone aesthetic, it provides an exceptional, high-adhesion base for finishing with Clay Stucco or Clay Marmorino.
UKU Clay Decorative Plaster is an ideal finishing solution for dry interior spaces, providing an elegant and natural aesthetic for walls and ceilings. This versatile mineral plaster allows for both refined smooth surfaces and expressive textures. Available in two grain fractions, it offers the flexibility to tailor the tactile character of any room.
UKU Clay Rustic Finishing Plaster is a versatile solution for leveling base-plastered surfaces and filling irregularities. It is designed to create a durable, textured final finish or serve as an efficient base coat when a minimal plaster thickness is required.
PURE EARTH PLASTER
UKU Pure Earth Plaster creates a rustic, earthy texture that brings a raw, natural essence to any space. It is specifically designed for achieving expressive, robust structures and artistic cracked effects.
UKU Hemp-Clay Plaster is ideal for leveling base surfaces and building up structural layers. While serving as a robust foundation, it can also be left as a stunning final finish—characterized by its coarse, organic texture and a beautiful, deep natural tone.
UKU Rammed Earth Mix is a structural clay mixture designed for building massive walls and restoring earthen buildings.The tamping process leaves characteristic horizontal layers, creating a warm, rustic texture with striking clay tones and natural character.
UKU Masonry Mix is designed for constructing and repairing the outer shells of fireplaces, stoves, ovens, chimneys, heat-retaining walls and heat benches in indoor environments. This versatile mixture is suitable for laying both unfired and fired clay bricks, as well as for filling ceramic stove tiles.
Unfired clay bricks, or compressed earth blocks (CEB), are pressed raw-clay bricks that are not kiln-fired. These unfired raw clay bricks are building blocks formed from clay and sand, suitable for constructing both load-bearing and non-load-bearing walls.
Engineered to replicate the strength of natural clay soil, making it ideal for structural building, creating clay blocks, and sculpting organic forms or curved corners. This versatile mixture is also perfectly suited for renovating earthen buildings and constructing durable clay floors.
Clay adhesive plaster is used in clay wall renovation works. When restoring a clay wall, the entire surface is covered with a thin layer of the adhesive mixture immediately before plastering or filling. This ensures ideal adhesion between the surface and the infill.
UKUNAKS universal clay plaster is made from greyish-blue clay, whose unique tone and mineral texture create a calm and nature-inspired interior.
Natural Clay Materials: FAQs
How do I choose the right natural clay material for my project?
The right natural clay material depends on your project’s purpose, substrate, and desired finish. For decorative interiors, Clay Decorative Plaster, Clay Stucco, Clay Marmorino, and natural clay paint create breathable surfaces with different textures and levels of refinement. For structural or traditional building work, clay blocks, compressed earth blocks, Rammed Earth Mix, or Cob Mix may be more suitable.
What finishes can be achieved with natural clay products?
Natural clay products offer wide design flexibility. Depending on the product, pigment, and rendering method, you can create smooth matte surfaces, polished stone-like effects, rustic textures, or expressive, natural, earthy finishes. Clay Decorative Plaster, Clay Stucco, Clay Marmorino, and Pure Earth Plaster each offer a distinct visual character, creating the warmth, depth, and timeless character that only natural clay colours can provide.
What is the difference between clay paint, clay stucco, and clay marmorino?
Natural clay paint provides a soft, velvety finish for interior walls. Clay Stucco is a decorative plaster that can create silky matte surfaces or polished, high-gloss effects. Clay Marmorino offers a refined stone-like appearance with matte or satin-gloss finishes. All three are classed as breathable clay materials, but each creates a different level of texture, depth, and refinement.
What are the advantages of using natural clay materials over conventional plasters?
Unlike many conventional plasters, natural clay materials remain breathable – helping walls regulate moisture rather than trapping it. Used as a building material for centuries, clay has been proven to support healthier indoor environments, help regulate humidity naturally, and create durable, repairable surfaces. Here at UKU, our eco-friendly clay products are handcrafted using traditional methods in Estonia from carefully selected natural ingredients.
How do natural clay finishes improve indoor air quality and humidity regulation?
Natural clay finishes absorb excess moisture when humidity rises and release it again when the air becomes drier. This natural “buffering” effect helps create more stable indoor conditions, and also reduces the likelihood of condensation and mould growth. Combined with mineral-based, low-emission formulations, clay products help support calmer, healthier interior spaces.
Can clay building materials be used for structural applications?
Yes. While decorative clay plasters and paints are primarily designed for surface finishes, some clay building materials are suitable for structural rendering and applications. Rammed Earth Mix, Cob Mix, and specialised clay blocks, for instance, might be used as part of traditional and contemporary earth construction, depending on structural design, engineering requirements, and local building regulations.
Are clay blocks and compressed earth blocks suitable for load-bearing walls?
Yes, when correctly designed and manufactured, compressed earth blocks (CEBs) and other clay blocks can be suitable for both load-bearing and non-load-bearing walls. Large format clay blocks offer thermal mass, durability, and the natural performance benefits associated with earth construction. As always, professional design, rendering, and engineering guidance should be followed.
