Summary

  • ✔ WEED CONTROL USING SODIUM HYPOCHLORITE SOLUTION - Unfortunately there is no such thing as a weed-free surface. If organic material is allowed to accumulate on a surface it will only be a matter of time before weeds & other plants begin to grow. Sodium Hypochlorite solution is regarded as one of the best patio cleaners because it will also control weeds and will deter re-colonisation for a period of weeks, even months
  • ✔ TEST - Before undertaking any cleaning operation, a trial should be carried out on a small, preferably inconspicuous area, to determine the effect of the chemicals before treating a large area
  • ✔ APPLICATIONS - Swimming Pools, Patios, Moss, Algae Remover, Bleaching Agent, Water Purification, Odour Removal, Lab Use
  • ✔ IMPORTANT NOTES - This product is not for use on lawns, flowerbeds, vegetable plots or around trees and shrubs. Keep people and pets away from the treated area for 2 days.
  • ✔ EFFECTIVE - To use Sodium Hypochlorite as a Moss, Algae, Lichen, Weeds and Mould remover you can apply the solution and leave and within minutes you will begin to see results. Take the hard work out of cleaning your drive, block paving, fences, walls, brick work, stonework, paths, patios decking, gravelled areas and even roofs.

(5L) Sodium Hypochlorite 14-15% HIGH Strength Patio Block Paving Driveway Cleaner | Algae Weed Moss Mould Blackspot & Lichen Killer Remover Description

Guidance for using Sodium Hypochlorite as a Patio Cleaner & Moss Remover

SUPER FAST : MOSS, ALGAE, LICHEN, WEEDS & MOULD - REMOVER!

Sodium Hypochlorite Solution is used for more stubborn stains as you need the EXTRA strength solution, which is 50% stronger than the heavy duty solution and may be diluted with up to 6 parts water and 1 part Sodium Hypochlorite 15%.

To use Sodium Hypochlorite as a Moss, Algae, Lichen, Weeds and Mould remover you can apply the solution and leave and within minutes you will begin to see results. Take the hard work out of cleaning your drive, block paving, fences, walls, brick work, stonework, paths, patios decking, gravelled areas and even roofs.

Use neat to shift old and stubborn growth or dilute for routine maintenance. Even when diluted Sodium Hypochlorite still outperforms the rest* and can treat up to 10m² per litre. Spruce up the grounds around your home this Spring and make your home the envy of your neighbours.

Important Notes:

- This product is not for use on lawns, flowerbeds, vegetable plots or around trees and shrubs.

- Keep people and pets away from the treated area for 2 days.

IN GENERAL THE FOLLOWING PRECAUTIONS SHOULD BE TAKEN:

When using chemicals, protective clothing such as gloves, goggles, boots and overalls should be worn.

Adequate ventilation is required when using chemicals in confined spaces.

When using flammable materials; cigarettes, naked flames and other sources of ignition should be carefully controlled.

How to use Sodium Hypochlorite on Paving/Block Paving

SAFETY FIRST:

DO NOT use this product on lawns, flowerbeds, vegetable plots or around trees and shrubs.

Safety eye goggles, boots, overalls, gloves should be worn when using this product – FULL PPE should be worn. Any exposed clothes should ideally be destroyed after.

Adequate ventilation is required when using chemicals in confined spaces.

Do not expose to naked flame, cigarettes and other sources of ignition

Keep away from pets and other animals from treated areas for at least 2 days.

DO NOT DRINK/INGEST.

DO NOT allow contact with skin. If the liquid comes in contact with skin it may irritate. Wash off immediately with plenty of cold water.

Fumes from Sodium Hypochlorite could cause coughing, irritation and extreme cases could cause blistering and burning of the skin.

Keep away from Acids.

 

Exposure to Sodium Hypochlorite can cause the following symptoms:

Coughing from fumes

Irritation, blistering and burning when in contact with skin

Stomach and abdominal pain if ingested

 

Care from exposure:

Seek immediate medical assistance

DO NOT make someone throw if they have ingested Sodium Hypochlorite – it will burn as the liquid comes back up. Do not give water or milk to swallow unless directed by a medical professional.

If in contact with the skin or eyes, flush for at least 15 minutes with cold water.

For those who have inhaled any toxic fumes due to exposure, move them immediately to fresh air.

This product, especially when used neat could be corrosive to certain metals such as brass (aluminium, naval and silicon) bronze, carbon steel, cast iron, Hastelloy, Inconel, nickel, stainless steels (types 304/347, 316 and 400 series) and silicon copper. Concentrated sodium hypochlorite is corrosive to most metals, including aluminium, copper, brass, bronze, carbon steel, Hastelloy, Inconel, lead, Monel, nickel and stainless-steel type 400 series. Sodium hypochlorite solutions are not corrosive to tantalum, titanium and zirconium. Dilute solutions are not corrosive to Hastelloy C/C-276 (10%), Incolloy (5%) and high silicon iron.

Corrosivity to Non-Metals:

Sodium hypochlorite solutions attack some plastics (such as nylon, Bisphenol A-fumarate and isophthalic polyesters), elastomers (such as soft rubber, neoprene and nitrile Buna-N) and coatings (such as coal tar epoxy, epoxy and vinyls).

Sodium hypochlorite solutions do not attack acrylonitrile-butadiene-styrene (ABS), Butyl rubber, isoprene, hard rubber, natural rubber, polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyethylene, polypropylene, polystyrene, Teflon and Viton.

 

DILUTION:

The dilution will depend on the type of paving, but as a general use we discuss with standard paving (natural stone or concrete) and block drives.

Assistance with a brush is highly recommended as it will help reduce the amount of applications required on stubborn stains.

Start-up mix: Three parts water to one part Sodium

Stubborn Mix: For use on areas showing considerable amount of moss/algae/stains an initial dilution of two parts water and one part Sodium.

Neat application: Sodium Hypochlorite can be used neat too, though this is not always advised.

 

SAFETY NOTE: ALWAYS ADD THE SODIUM HYPOCHLORITE TO WATER.

APPLICATION:

It is highly recommended that you test a small patch before full use of Sodium Hypochlorite.

The Sodium Hypochlorite can be applied via a watering can, or simply by preparing the liquid in a bucket and swilling it over the surface. Leave it to work for a few minutes and then rinse off with plenty of clean water.

The Sodium Hypochlorite will be effectively neutralised by dilution and by contact with soils and other surfaces.

When using a brush or power washer please take care of splashes and spill.

Does the job efficiently

This is the ideal product to restore flagstones and patios.easy to mix and apply to get the best results.A grrate advantage is that it kills weeds which can grow between the flags.Simple rinsing after a couple of hours produces gleaming flags as new
