Pressure washing stone statues and garden urns can damage the detail, and should be avoided. Stone King®is designed to work without the need to pressure wash. Stone King® adheres to the surface of the stone and penetrates, breaking down organic matter. Simply rinse with hot water and the residue will dissolve.


Naturally Restores the original colour to ornamental stone and terracotta by removing Patio Black Spots and Green Algae. Simply apply, rinse with hot water and admire! No pressure washing. No scrubbing, no problem.

Monumental performance from a monumental product.



Place the object on a hard surface where the residue can easily be washed away – do not treat on grass.


Cover surrounding foliage to protect from overspray, especially on a windy day.


Hold the container at arm’s length – Spray on neat and saturate the ornament, working from top to bottom.


Immediately apply a second coat of Stone King®Stone Restorer, saturating the ornament as before.


What to expect: You will start to notice a transformation within 15 minutes of application. Green algae will disappear before your eyes, the black spots will begin to break up and the natural colour of the stone will return.


NO NEED TO SCRUB or PRESSURE WASH! – After 2 hours, simply remove using a pneumatic garden sprayer filled with hot tap water (not boiling).


Once dry – Re treat remaining black spots or organic growth. On very old stone, the larger the spots with deeper roots may require repeat applications.


For heavily soiled items or taller statues, lay items on its side. This will increase ‘dwell time’ ensuring Stone King®Monumental Stone Restorer ceases to work when dry. Gradually ‘roll’ the item and repeat the above process.


Stone King®Preventer is a unique formulation which protects garden ornaments against the formation of ‘Patio Black Spots’. These forms after two years, initially blighting the appearance of garden stone work eventually engulfing the entire surface! Apply to either new garden ornaments or stone art within 6 months of purchase. If the surface shows any sign of organic growth, buy and apply Stone King®Stone Restorer instead.

Stone King® Preventer can also be used on any stonework, previously treated with Stone King® Stone Restorer and should be applied before the anniversary of this previous treatment.

Stone King®Preventer naturally prevents ‘Patio Black Spots’ forming by preventing them from germinating, protecting and maintaining your garden ornaments, avoiding the use of acid or caustic based products.

Stone King® Preventer is NOT a cleaner of dirt, nor a sealer. It will, however, gently remove green and red slime and staining that appears on garden ornaments and other decorative stonework, during the autumn and winter months, without the need to pressure wash the delicate surface.
