Lime Plaster Surface Preparation & Application Process
At Royal Touch, we believe a flawless finish begins long before the final coat of lime plaster is applied. Every step of our process is designed to ensure strength, consistency, and a seamless aesthetic outcome.
Preparing the Base for Lime Plaster
-
Walls and ceilings must be built straight and true, with no unevenness that could show through the finish.
-
The surface is cleaned thoroughly so it is free from dust, oil, curing agents, paint residues, or any impurities that can interfere with adhesion.
-
In cases of uneven absorption, apply two coats of a high-quality water-based primer to stabilize the surface and achieve uniform suction.
Creating a Foundation Layer
-
A finely applied first coat is spread across the surface to act as the foundation for the plaster.
-
We ensure the first coat is smooth and level, as even the slightest undulation or roughness at this stage will transfer to the final layer.
Applying Lime Plaster
-
Our craftsmen apply two thin coats of lime plaster, each layered with precision.
-
The first coat is allowed to partially dry (between 40–60%) before the second coat is laid.
-
For a more polished, subtle texture, the second coat is added sooner.
-
For a rustic, tactile finish, the base coat is left to dry slightly longer.
-
The surface is then left to cure overnight or until completely dry before sealing.
Detailing & Protection
-
Every layer is checked and refined to avoid imperfections that might reflect in the finished surface.
-
Once dry, we seal the plaster with a breathable organic sealer that enhances durability while retaining the natural character of lime.
-
For decorative finishes like lime-wash glazes or concrete effects, we add custom glazes and carefully wipe them down for the desired tonal depth.
-
In outdoor or high-moisture areas, we finish with coat of PU sealer, ensuring long-lasting protection against weather and water exposure.
Final Thickness
-
The complete Royal Touch lime plaster system achieves a refined finish with a slender build-up of approximately 1.5 mm—thin enough for design flexibility, yet strong enough for long-term performance.
