Mould, green algae and black lichen stains on my concrete paving

 

The Stone Doctor recommends our “Stontex All-In-One Outdoor Cleaner” which is an acid-free cleaner that removes all types of organic stains from natural stone, concrete, tarmacadam and decking.  A 5 litre bottle should be enough to clean an average of 30-50 metre squared area.

The Stone Doctor recommends that all natural stone, concrete and brick should be sealed once the material is clean and dry.

If you have concrete paving bricks then we recommend a sealer called “Resiblock Superior” which is a two coat treatment and comes in either a matt or gloss finish. The coverage rate is 2 square metres per litre which covers both coats. The coverage rate is 2 square metres per litre which includes both coats. This treatment also enhances the colour of your paving bricks and has a unique no oil stain guarantee.

If you have concrete paving slabs then we recommend  a sealer called “Resiblock Resiecco” which is a one coat treatment.  The coverage rate is also 2 square metres per litre. This treatment does not enhance the colour but keeps the natural look of the slabs and also protects against oil stains.

N.B. Both these treatments seal your concrete paving and also bind the jointing sand between the pavers.
