The Bostik Cementone Brick & Patio Cleaner excels in restoring the aesthetic appeal of various outdoor hard surfaces. Its fast-acting formula means users can see results quickly, significantly reducing the time and effort typically associated with manual scrubbing. For instance, dried mortar splashes on newly laid brickwork can be effectively dissolved, or green algae growth on a patio can be eradicated, revitalizing the area.When dealing with light dirt or general grime, diluting the cleaner as per instructions allows for efficient cleaning of larger areas, such as an entire paved driveway. For more embedded or severe issues like thick limescale deposits or deep-seated mortar stains, applying the product neat (undiluted) maximizes its powerful chemical action.The coverage of up to 4m² per litre (when undiluted) means a 5L bottle can treat up to 20m² of surface, which is substantial for average-sized patios or brick walls. Application by brush ensures thorough coverage and allows the user to work the solution into crevices and heavily soiled areas for optimal results. Always ensure to rinse thoroughly after application to prevent residue buildup.

Setup & Application1. Preparation: Ensure the area is clear of loose debris. Protect adjacent plants or surfaces not intended for cleaning. Wear appropriate personal protective equipment (PPE) including gloves and eye protection.2. Dilution (if needed): For standard cleaning or less severe stains, dilute the cleaner with water. Refer to the product label for specific dilution ratios. For severe stains, apply neat (undiluted).3. Application: Apply the cleaner directly to the surface using a brush. Ensure even coverage.4. Dwell Time: Allow the cleaner to dwell on the surface for the recommended time (check product label for specifics, typically a few minutes) to allow it to penetrate and break down stains.

Thoroughly rinse the treated area with plenty of clean water, preferably using a hose or pressure washer to remove all traces of the cleaner and dissolved grime.### Compatibility- Suitable for: Paving, paths, concrete, and brickwork.- Not suitable for: Painted enamel, stainless steel, decorative brass, aluminium, marble, natural limestone, sandstone, terrazzo, or lime/silicate bricks.
