  1. David Ford

    Very pleased with this product and the excellent service and useful tips received from Simon. My patio now looks as good as new where previous attempts at pressure washing alone couldn’t shift the spots. Highly recommended.

  2. Delia Coburn

    I purchased the Patio Black Spot Remover for artificial stone and was totally satisfied with the results. I’m in the process of buying some more for the drive.

  3. Norman Grunbaum

    I don’t know what is in that stuff but just to say it does work. Our garden is looking great again.

  4. Michele

    Came across an advert for this product in a gardening magazine, the results looked amazing. As I was looking at replacing my patio I thought I would give this product a go. I followed the instructions and although I hoped for the same results as the the web site and magazine showed I was a bit sceptical. Well I am absolutely delighted with the results, my patio really does look as good as new! This product is amazing and I will recommend it to anyone with a black spotted hideous patio! It really does transform it into a lovely like new patio, fabulous, can’t praise this product enough…. over the moon with the results.

  5. Julie Hemsworth

    Was very sceptical and hesitated to buy this expensive product but all else had failed and the only remaining solution was a new patio as over the past two years the black spot had become worse and unable to be removed by power washing. We did this as a DIY project and although it had to be power washed well before and after treatment I was delighted with the result. As the sun was drying the patio it became clear that this product really does work!

HOW TO USE

Prior to use, pressure wash the area to remove any surface dirt and loose debris. It is important the ‘Patio Black Spot Remover’ comes into direct contact with the surface of the stone and the ‘black Spots’. Any surface dirt will reduce the effect of this product.

DO NOT APPLY IN DIRECT SUNLIGHT OR WHEN RAIN IS IMMINENT.

A dry overcast day when rain is not forecast is ideal. The product works when wet, if it dries too quickly the performance will be reduced.

Ensure this product does not come into contact with fabrics or furnishings.

DIRECTIONS

  1. Use neat – DO NOT DILUTE – Pour our solution into a pneumatic garden sprayer. (A ‘Hozelock’ 5L or 7L sprayer is recommend. Do not use a hand sprayer.) Pressurise the sprayer.
  2. Apply the product to a dry surface, as a fine mist and saturate the surface.
  3. If you have not used the product before. Treat just one slab first. The older the stone, the more treatments it will require. The product will remove every single last spot. By completing one slab first, this will give you an indication of how many treatments your stone will require. Only when you have removed all the black spots from the first slab, continue with the rest of the area.
  4. DO NOT EXCEED THE MAXIMUM RECOMMENDED COVERAGE OF 5 SQM PER EACH 1L OF PRODUCT.
  5. Once applied, allow to cure for a period of 2 hours.
  6. Remove using a pressure washer, ideally with a minimum flow of 7 litres per minute. Use the fan jet attachment to sweep the dirt away. Other attachments such as circular spinning attachments will not give you the best results.
  7. Any black spots that remain, simply retreat (when the surface is dry) allow to cure for 1 hour then wash off.
  8. Repeat this process until no black spots remain.
  9. Apply the Patio Black Spot Preventer 12 months later. Do not seal the patio.

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.

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 product doesn’t come into contact with skin, eyes or respiratory tract. In the event product does comes into direct contact with the body, immediately rinse with water.
