ProJoint PRO-810 Invisible Natural Stone & Paving Sealer – Solvent Based – 1L, 5L & 25L

ProJoint PRO-810 Invisible Natural Stone & Paving Sealer – Solvent Based ProJoint PRO-810 is a solvent-based invisible paving sealer designed to provide long-lasting protection while maintaining the natural appearance of the surface. Unlike colour-enhancing sealers, PRO-810 is designed to protect without intentionally darkening or enriching the colour of the paving, making it ideal when you want to preserve the original look of your stone. The penetrating formulation helps protect natural stone and compatible concrete surfaces against water, oil, grease, everyday staining and weathering while remaining breathable. Available in 1 litre, 5 litre and 25 litre sizes, PRO-810 is suitable for everything from smaller paving areas to large patios and professional landscaping projects. Important – When Can I Apply PRO-810? Newly installed paving should be left for a minimum of 8 weeks before applying PRO-810. This allows moisture within the paving and installation to dissipate before the solvent-based sealer is applied. The paving must also be completely dry before sealing. If the paving has been cleaned prior to application, allow it to dry thoroughly for at least 2 days before applying PRO-810, subject to weather and site conditions. Invisible Protection. Natural Finish. PRO-810 is the ideal choice when you want the protection of a quality paving sealer without noticeably changing the appearance of the stone. Once correctly applied and dry, it provides an invisible protective treatment that allows the natural colour, texture and character of the paving to remain the focus.
