Depending on the dilution rate used, this product should cover up to 25m² per litre. Available in 2.5L and 5L. HOW TO APPLY: 1. Remove any dust and debris from the work surface before beginning, and make sure you have adequate personal protection, such as gloves , appropriate protective eyewear , a face mask , and clothing. 2. Prior to use, we always recommend performing a small test application in an inconspicuous area. This will indicate the product's suitability and effectiveness for your surface. 3. Ultra Cleaner Pro can be used straight to remove waxes/coatings or watered down up to 10 parts water to 1 part for heavily stained areas, depending on the discoloured or soiled area. 4. Before applying the cleaner to the stained area, wet the space with clean water. Allow the cleaner to sit for 15 to 20 minutes, but do not allow to dry on the surface. 5. After 15 to 20 minutes, agitate solution with a stiff brush and clean water, exfoliate, and rinse thoroughly with clean water. In cases of heavy soil erosion or staining, repeat the process, increasing the volume of cleaner as needed.
