Now, let’s move to the main topic—how to apply Lime and Clay Heritage Plaster professionally. Tools and Materials You’ll Need To begin the application process, gather the following tools and materials: Materials Lime and clay heritage plaster mix (available from Balaji Wall Texture) Clean water Optional: Natural pigment for color tinting Bonding agent (for modern surfaces, if required) Tools Trowel (steel or wooden) Hawk board Mixing bucket or mechanical mixer Sponge or sponge float Spray bottle Paintbrush (for detailing and touch-ups) Drop cloths and masking tape (to protect adjacent surfaces) Surface Preparation 1. Assess the Surface Lime and clay plaster adhere best to porous, breathable surfaces like stone, brick, and mud blocks.

3. If applying on cement, gypsum, or painted surfaces, apply a breathable bonding agent recommended by Balaji Wall Texture. 2. Clean the Surface Remove dust, grease, or loose particles using a wire brush or damp cloth. Ensure the surface is slightly rough or textured for better adhesion. 3. Dampen the Wall Lightly spray the wall with clean water using a mist sprayer. This helps prevent the substrate from pulling moisture too quickly from the plaster. Mixing the Plaster Balaji Wall Texture provides pre-mixed Lime and Clay Heritage Plaster, but if mixing on-site: 1.  2.  3.  Combine lime putty, clay, and sand in a clean mixing container. Add water gradually while mixing until a creamy, spreadable consistency is achieved. Let the mixture rest for at least 30 minutes to allow the particles to fully hydrate. Optional: Add natural pigments during mixing if you want a tinted plaster finish. Application Process Step 1: Apply the Base Coat (Scratch Coat) Load your hawk board with the plaster mix and scoop it onto the trowel. Apply the first thin coat (approx. 3-5mm) evenly over the dampened wall. Use firm, sweeping trowel motions to spread the material consistently. Scratch the surface with a notched trowel to create keying for the next layer. Allow this coat to dry for 24-48 hours, misting occasionally to prevent rapid drying or cracking. Step 2: Apply the Second Coat (Brown Coat) Apply the second coat at the same thickness, filling in scratches and smoothing the surface. This layer builds strength and evens out imperfections. Let it cure slowly for another 24-48 hours, misting as needed. Step 3: Apply the Final Finish Coat The final layer is typically 1-2 mm thick and defines the appearance of the wall. Use gentle pressure and smooth strokes to achieve the desired texture—whether rustic or polished. Optional: Finish with a sponge float or steel trowel for different effects (matte, slightly burnished, or stone-like).

4. Curing and Finishing Touches Cure Slowly: Allow the plaster to dry naturally and gradually. Avoid direct sunlight or strong wind during the drying process. Final Texture: You can gently sponge or polish the surface within the first few hours to modify the texture. Protect: After curing, a natural sealant like beeswax or linseed oil can be applied to enhance durability and resistance to stains (especially in kitchens or bathrooms). Common Mistakes to Avoid 1.  Applying on Non-Breathable Surfaces Without Primer Always ensure compatibility between substrate and plaster. Overworking the Finish Coat Too much smoothing can weaken the surface or create shine spots. Skipping the Curing Process Drying too quickly can lead to cracks. Always mist when necessary. Incorrect Thickness Applying too thick a coat can cause poor adhesion and uneven drying. 2.  3.  4.  Professional Tips from Balaji Wall Texture Always test a small patch before large-scale application, especially with colored plasters. Keep tools clean and rust-free to avoid contamination. For a heritage restoration, match the original plaster composition as closely as possible. Maintain a consistent room temperature for optimal drying—between 15°C to 30°C is ideal.
