Calculate the amount you will need to clean, seal and maintain your surface.
Enter the surface area in square metres (calculated by measuring one side in metres and another side at right-angles to the first side and multiplying the two measurements) and the coverage calculator provides the amount required, in litres.
Once you have established the surface area, porosity and preferred products, then use the table below to work out quantities required.
This test will help to establish whether the surface porosity of the tile is high, medium or low. When the intensively cleaned or new /untreated surface is completely dry, place a teaspoon of water on a tile and time how long it takes for the water to absorb.
High Porosity - Water is absorbed within 5 minutes: 4 coats of sealer required in normal conditions.
Medium Porosity - Water is absorbed within 15 minutes: 3 coats of sealer required in normal conditions.
Low Porosity - Water is absorbed within 1 hour or longer: 2 coats of sealer required in normal conditions.
