SummitSeal - Slate Sealer - Colour Enhancer

Advanced Impregnation Technology
Formulated to penetrate deep into the foliated structure of slate, this sealer creates a robust internal bond rather than a superficial film. This impregnating action allows the stone to breathe while locking in a premium satin sheen that revitalises the natural grey and charcoal tones of the slate, preventing the "washed out" look caused by weathering. Unlike basic varnishes, it works within the stone to provide structural reinforcement.

Long-Lasting Defence
Engineered for a lifespan of up to 5 years, this coating provides industrial-level resistance against UV degradation, preventing colour fade. It establishes a hydrophobic barrier that actively repels water, oil, and organic contaminants, making it highly effective at stopping algae and black spot growth. It also hardens pointing, protecting the structural joints from erosion and weed penetration to reduce long-term maintenance.

Professional Application
Suitable for both internal and external slate surfaces, this sealer is designed for application via sprayer or roller. Crucially, it must be applied in thin, even coats to avoid pooling or "whitening," ensuring a crystal-clear finish. It is strictly for use on bone-dry substrates and is not compatible with resin-based grouts, ensuring a professional, non-yellowing result on patios, driveways, and floors
