Prepare the Surface
Begin by thoroughly cleaning your window sills to remove any dirt, debris, or old paint. This ensures a smooth application surface for the primer.
Apply Quartz Primer
Use a brush or roller to apply a coat of Decomin Quartz Primer. This step enhances adhesion and provides a stable base for the Decosill coating.
Apply Decosill Coating
With a trowel, spread a tight coat of Decosill over the primed surface. Smooth it out evenly and allow it to cure for a durable, stone-like finish.
Final Touches
Once the Decosill has cured, inspect the surface for any imperfections. Make any necessary touch-ups to ensure a flawless finish.
