ProJoint PRO-410 Colour Enhancing Natural Stone Sealer – Solvent Based – 1L, 5L & 25L

ProJoint PRO-410 Colour Enhancing Natural Stone Sealer – Solvent Based ProJoint PRO-410 is a solvent-based colour enhancing sealer designed to deepen and enrich the natural appearance of porous natural stone and compatible concrete surfaces. Its penetrating formulation brings out the natural colour and character of the paving while leaving a matt finish and providing long-lasting protection against everyday exposure and weathering. Ideal for natural stone patios, paths and landscaping projects, PRO-410 penetrates into the surface to help protect against water penetration, staining, dirt, grime and algae while remaining breathable. Available in 1 litre, 5 litre and 25 litre sizes, it is a professional-strength option for customers looking to both enhance and protect their natural stone paving. Important – Wait 8 Weeks Before Sealing New Paving Newly installed paving should be left for a minimum of 8 weeks before applying PRO-410. 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 before application, allow it to dry thoroughly for at least 2 days before applying PRO-410, with additional drying time allowed where required by the weather, paving material and site conditions. Enhance the Natural Colour of Your Stone PRO-410 is designed for customers who want their natural stone to look richer and more defined rather than completely untreated. The colour-enhancing treatment deepens the natural tones within the paving while maintaining a matt appearance, making it particularly effective on natural stone where variation in colour and character is part of the finished look. Main Benefits ✓ Enhances and deepens the natural colour of stone ✓ Solvent-based penetrating formulation ✓ Matt finish ✓ High surface penetration ✓ Breathable treatment allows moisture vapour to escape ✓ Helps protect against water penetration ✓ Helps protect against staining, dirt and grime ✓ Helps resist algae and weathering ✓ UV stable for external paving applications ✓ Available in 1L, 5L and 25L sizes PRO-410 or PRO-420 ECO? Both products are designed to enhance and protect natural stone, but they use different formulations.
