Our Mapei UltraCare Smooth Silicone Spray is a water-based smoothing solution designed to finish and refine sealants after application. Suitable for use with all types of sealant, it helps create a smooth, compact surface without hollows, improving the overall appearance of the joint. Its biodegradable formula reduces the accumulation of dirt and helps minimise the risk of future mould growth, leaving a clean and professional finish.
