Description
Black spots ruining the look of your once pristine patio? Wondering how they got there, what will get rid of them? Patio Black Spot Remover and Preventer.
Black spots are stubborn and even hours of pressure washing will not remove them. The more you pressure wash, the more you damage the surface of your stonework leaving it porous and susceptible to frost damage and further dirt/grime infestation.
Patio Black Spot Remover will eradicate the black spots – and The Patio Black Spot Preventer will control and prevent their return!
There are specific Patio Black Spot Remover formulas for natural stone, artificial stone and block paving all available in either 2 or 4 litre bottles. There is also a 2.5 litre bottle of preventer that can be applied annually.
PATIO BLACK SPOT REMOVAL FOR NATURAL STONE
Patio Black Spot Remover is currently the only product developed specifically to remove those hideous ‘Black Spots’ and restore the natural colour your garden stonework. Patio Black Spot Remover for Natural Stone will remove ‘Black Spots’ from Indian Sandstone, York Stone, Limestone (including Bath and Portland Stone), Purbeck stone and other Natural Stones. Patio Black Spot Remover will restore the colour back into your stonework that you thought you had lost forever.
Patio Black Spot Remover for Natural Stone removes Black Spots, but will also eradicate Green and Red Algae and white fungi growth, gently cleaning the Stone whilst reviving and enhancing the original colours, giving that “Just Laid” look to your Terrace, Paths and Patios.
Directions:
Prior to use, pre wash the affected area to remove any loose debris ensuring the Patio Black Spot Remover can come into direct contact with the Black Spots and stone’s surface. Apply on a cool day, if it dries too quickly the performance will be reduced, on a hot day apply in the evening and allow to dwell overnight. Only apply when the surface is dry, do not apply when threat of rain is imminent. Watch video.
1/ Use neat – DO NOT DILUTE – Pour our solution into a pneumatic garden sprayer. Pressurize the sprayer.
2/ Using a fine mist spray apply a flood coat, working in sweeping strokes across the stonework. Immediately after apply a second continuous pass at right angles to the first to ensure complete coverage.
3/ DO NOT EXCEED THE MAXIMUM RECOMMENDED COVERAGE OF 5 SQUARE METRES PER LITRE. Exceeding the recommended coverage rate will reduce the performance of this product. Coverage will vary depending on surface porosity and profile, e.g when treating sloping areas or riven surface, beware of surface run off and retreat as necessary to ensure correct coverage.
4/ Allow to cure for a minimum period of 2 hours. In cases of severe infestation or when treating very porous stone allow the product to dwell overnight.
5/ Remove using a pressure washer ideally with a minimum flow of 7 litres per minute. Use the fan jet attachment approximately 50mm from the surface. Adjust this distance to suit your application.
6/ Retreat if necessary to remove any remaining Black Spots or ‘Ghosting’. You must allow the surface to dry before retreating.
To maintain your garden stonework and stop the ‘return of the Black Spots’, buy and apply our Patio Black Spot Preventer annually. This will kill any ‘Black Spot’ spores before they have the chance to germinate and turn into spots and will also remove green algae without the need to power wash!
NB. DO NOT APPLY PATIO BLACK SPOT REMOVER WHEN THE THREAT OF RAIN OR FROST IS IMMINENT
The Patio Black Spot Remover is quickly and readily biodegradable. The effluent if washed into soil, flower beds or lawn will breakdown rapidly. This product will not affect surrounding lawns or foliage in diluted state. Keep animals and unprotected persons off the treated area until dry. Ensure this product does not come into contact with fabrics or furnishings.

WHAT ARE BLACK SPOTS?
The patio black spots that grow on your garden stonework are actually spots of Black Lichen! The spores from the Black Lichen start life as tiny dust-like spores growing on the underside of leaves on trees and plants. These spores are carried, by the wind and the rain, onto your stonework in their millions. Once they have landed the spores have a 2 year germination period which means, for the first 2 years of having the patio laid it would of still looked really clean without a spot in sight! However on the third year the colour in the stone would dull and it would look like someone has flicked ink across your stonework leaving tiny ink splatters. The reason why they grow on your garden stonework is because they feed off the minerals within the stone. Once they have exhausted an area of the stone of all the minerals they grow in search of more, not only across the stone (which gives it its spot like appearance), but also down into the stone effectively rooting itself down into the pores of the stone growing at about 2mm a year.
Encouraged by warm, damp conditions, these unsightly spots will only get worse if left untreated, ruining the original beauty of your garden stonework.
HOW WILL I KNOW IF MY PATIO HAS THEM?
Oh you’ll know! Black spots are incredibly resilient and can’t be removed with a simple spray clean. So if you’ve tried washing your stonework and the spots remain then there’s your answer.
HOW CAN YOU GET RID OF THEM?

WILL THEY STAY GONE?
