Top Tips:

• Make sure your patio is dry, and that you have swept any loose dirt/debris off your tiles
• Choose a test tile and follow the instruction on the bottle, to establish how many treatments you will need
• Multiple application could be necessary depending on the age, texture and stone of your patio

Very old patios, could have very deep set black spots and grime, so may need a few treatments

If the stone used for your tiles is porous you will also need to use more than one treatment, as the solution may be absorbed or pass through the stone.
