The Range
Three Finishes.
Endless Possibilities.
ToneCoat Sealer
Matte
A completely flat, chalky finish that lets the natural texture and depth of your plaster breathe. Perfect for a raw, organic look.
ToneCoat Sealer
Satin
A soft sheen that enhances colour depth and warmth. The most versatile finish — works beautifully in living spaces, hallways, and bedrooms.
ToneCoat Sealer
Gloss
A high-shine, polished finish that transforms plastered walls into a statement surface. Ideal for feature walls, kitchens, and wet areas.
Why It Matters
Why You Should Always Seal
Protects Your Finish
A sealer locks in the colour and texture, protecting it from marks, scuffs, and everyday wear for years to come.
Moisture Resistance
Without sealing, plaster is porous and vulnerable to moisture. A sealer makes your finish suitable for kitchens, bathrooms, and humid spaces.
Enhances the Look
Sealing deepens colour, enriches texture, and adds a professional quality finish that makes the whole job look considered and complete.
Prolongs Life
A properly sealed ToneCoat finish will last significantly longer — reducing the need for touch-ups and keeping walls looking great for longer.
In the Meantime
What to Use Right Now
While our own sealer range is in development, we recommend using a general-purpose clear stone sealer or clear wax on your ToneCoat finish. These are widely available from most builders merchants and work well across the range.
Apply after the plaster has fully set and dried — typically 3–7 days depending on conditions. Always test on a small area first to check the effect on your chosen tone.
Our own ToneCoat Sealer range is coming. Engineered specifically for this system, it will offer superior compatibility, splash-proof and moisture-resistant protection, and a choice of matte, satin, and gloss finishes. Sign up above to be notified on launch.
