ProJoint ECO-820 Invisible Stone & Porcelain Sealer – Water Based – 1L, 5L & 25L

ProJoint ECO-820 Invisible Stone & Porcelain Sealer – Water Based ProJoint ECO-820 is a professional-strength water-based invisible sealer designed to protect natural stone, porcelain and compatible paving surfaces without intentionally changing their natural colour or appearance. It provides long-lasting protection while retaining the original look and character of the paving. The penetrating, breathable formulation helps protect against water penetration, staining, dirt, algae and weathering. Unlike solvent-based sealers that require newly installed paving to be left before treatment, ECO-820 can be used on new paving once the surface is suitably prepared and dry, making it an excellent choice for new patios and landscaping projects. Invisible Protection Without Changing the Look ECO-820 is ideal when you want to protect your paving without creating a colour-enhanced or wet-look finish. Once correctly applied, the invisible treatment allows the natural colour and texture of the paving to remain the focus while adding an additional layer of protection against everyday exposure. No 8-Week Wait Required As a water-based sealer, ECO-820 does not require the minimum 8-week waiting period associated with solvent-based sealers such as PRO-810. It can be used on newly installed paving once the paving is suitably prepared and dry, allowing new installations to be protected much sooner. Suitable for Porcelain & Natural Stone One of the major advantages of ECO-820 is its versatility. It is suitable for natural stone and porcelain paving, making it a particularly useful option for customers looking for one invisible, water-based treatment across a range of paving materials.
