StoneCare4U Slate Sealer - Matt Finish

This product is specifically formulated for external natural slate surfaces. For internal surfaces, please refer to products designed for indoor use to ensure compatibility and desired finish.

The protection is long-lasting, but the exact duration depends on environmental factors, foot traffic, and cleaning methods. Periodic inspection and reapplication may be necessary over time.

The coverage is up to 15m² per litre per coat. Two coats are recommended, and actual coverage can vary based on the porosity and texture of the specific stone surface.

No, it is critical that the surface is completely dry before application, and remains dry for at least 6 hours afterward. Application should only occur during dry weather conditions and within the specified temperature range.

If rain is forecast or starts, stop treatment immediately and cover the freshly impregnated areas. The surface requires a minimum of 6 hours of dryness after the final coat.

Clean sealed areas with a mild, pH-neutral cleaner or a very dilute solution of an outdoor cleaner. Avoid using harsh or abrasive cleaning agents, as they can negatively affect the treated surface.

No, this sealer is designed to provide an attractive matt, dry finish, maintaining the natural look of the stone without adding shine.

Ensure two "wet on wet" coats were applied to saturation. The surface may have been inadequately prepared or not completely dry before application. Reapply following all preparation and application instructions.

This can indicate moisture still migrating through the stone. Ensure the surface was completely dry for 72 hours prior to application and remained dry for 6 hours after. If moisture persists, further investigation into ground dampness may be needed.

This is noted as a potential effect. Always test in an inconspicuous area first. If the color change is undesirable, reapplication of sealer is not recommended to reverse the effect. Future treatments might use a different product if available and compatible.

Ensure consistent application using the recommended methods (sprayer, roller, brush). Avoid over-application in certain areas. For existing issues, gentle cleaning might slightly even the appearance, but a full re-application might be needed if severe.

The sealer helps prevent new growth by repelling moisture. Existing growth should be cleaned off before application. Regular cleaning with a mild cleaner will help maintain the appearance.
