Frequently Asked Questions


The most effective time to use a moss killing product is when the plant is most active therefore when it is growing.  Late winter, early spring and the Autumn months are the most active growing periods so, especially if using a systemic treatment such as Baticlean CR, this is the most effective time to start your treatments as the growing and active plant will absorb the moss killer and die over a few days.

If you are using one of our 'kill on contact' products, such as Batiface or Batifort, then the time of year is less important as the product does not require the plant to be active for it to work.

An older flat roof can be susceptible to moss growth as rainwater can pool on the surface. Stone chippings also provide moss with shade and can retain moisture; the perfect conditions for moss to grow, especially if in the shade. It is important to remove this moss as it may cause damage to the coating as it spreads and the surface expands and contracts with changes in the weather, causing small imperfections and allowing water ingress. Clumps of moss can break free and roll into gutters and cause blockages.

Given the construction of a flat roof, especially if old, it may not be safe to walk on the surface and so you should either seek the advice of a roofing contractor or use one of our telescopic brooms and extendable sprayer lances to tackle the job from the floor or edge of the roof.

Brush any loose stone chippings to one side and remove any loose moss, leaves or twigs so that you can treat the surface. If the surface is damp once uncovered, it would be a good idea to let it dry before treatment with Baticlean CR. Dilute it down 4:1 and spray all over the roof to kill any growth as well as the spores. Left on the surface, it will also prevent regrowth. If you are putting stone chippings back on the roof, then it would be a good idea to apply a second cost of Baticlean CR on the chippings.

The easy answer is that our telescopic lances will fit all the sprayers (apart from the hand sprayers) that we show on our website, both compression sprayers and knapsack sprayers.  Some of the units will need a small connector but other than that you can use any of our sprayers with the large telescopic lances.  The technical information of each sprayer will confirm if a connector is required or not.

If you are looking to connect our lances to a sprayer that you already own, we can't guarantee that they will connect with or without one of our connectors.

Moss will hold moisture which will slow the drying of a thatched roof and potentially stop it from breathing. Many people also find the growth of moss on a thatched roof unsightly and it will attract birds to the roof which can cause additional problems.  We recommend the use of Baticlean CR our systemic biocide and fungicide.

For further information on treating a thatched roof, or many other surfaces, please visit our Advice Page.

Baticlean CR can be applied using a watering can however you will not get the high coverage that you would with a sprayer. Coverage with a sprayer will be around 30m2 per litre but a watering can will give you far less coverage than this, even with a fine rose sprinkler.  So, if you have only a small area to be treated (and you don't already have a sprayer), then it is probably be easier to just use a watering can however, invest in a sprayer if you have a larger area (maybe over 100m2) or if you would plan to use it in the future.

When applying Baticlean CR to ensure an even coverage it is always best to use a sprayer. When using a sprayer, to protect plants from any spray drift, it is best to hold a piece of cardboard over your plants or invest in a spray hood which will reduce 'drift' helping you to direct your spray to where you want it.

We only sell our products directly through our website.  We do this so that we have control over the amount and quality of technical information that is available for our customers and, where possible, ensure that we are able to give the best information and assistance.

Any chemical, even those generally found under your kitchen sink, may be harmful to animals if not used in the correct way.

When applying our moss killing and surface cleaning products to a hard surfaces to treat growth such as moss, algae and lichen, then you must follow the usage instructions and if you have any queries then contact us and we will try to help you. Contact cleaners, such as Batifort and Batiface are designed to be rinsed after use so, make sure that the area is well rinsed and dry before letting animals, such as cats and dogs, onto the surface. Systemic cleaners such as Baticlean CR take longer to act as they are absorbed by the plant which will then die over a few days. It is left on the surface without rinsing so do not allow your pet access until the product and area is completely dry.  Preferably, keep dogs and cats away from the treated surface for 24 - 48 hours.

If you wish to kill and remove moss and algae on surfaces such as walls before applying a new coat of paint, then you can apply Baticlean CR which is a pH neutral systemic surface biocide and will not affect the paint.

Dilute Baticlean CR in water as per the usage instructions, spray on the surface and leave to act without rinsing. It will take a few days and then you can, optionally, clean down the surface with a brush and/or rinse. You can then apply another treatment of Baticlean CR if you wish to leave protection under the paint.

Baticlean CR has a maximum coverage rate of 30m2 per litre.  The size of a tennis court can vary as some will have larger areas outside of the playing area than others.  The playing area is fairly standard at around 300m2 which means that, if you were to treat the whole of this area, you would require around 10-litres of Baticlean CR.  Many courts can then have the same surface area outside of the court meaning that, in total, you would need around 20-litres to treat the whole of the playing area and surrounding area.

However, you need to know if you have to treat the whole area or just certain parts.  To help with this then visit our advice pages.

The difference between Batiface and Batifort is that Batifort is stronger out of the two as it kills black spots and is also more suited for pouros surfaces such as sandstone. Once applied using a sprayer, both Batiface and Batifort needs to be left on the surface for around 30 minutes then cleaned off using a pressure washer or a hose pipe and a brush.

Batiface should be diluted 50:50 which will cover 12 metre squared, for heavy soiled areas it can be used undiluted which will cover 6 metre square.

Batifort can be diluted 50:50 which will cover 10 metre square per litre or for heavy soiled areas it can be used undiluted which will cover 5 metre square per litre.


We have a wide range of spraying equipment to suit all requirements.

Generally the compression sprayers are a smaller capacity and are carried at the shoulder with a pump at the top. Some of the compression sprayers have optional backstraps so that they can be worn on the back. The knapsack sprayers are larger capacity, are worn at the back and have a handle at the side for pumping.

Check the pH of the chemical that you are using and if you are intending extended use of acids or alkalines then you can choose chemical resistant equipment. Baticlean CR, for example, is pH neutral, so any of the standard sprayers would be fine.

In order to push liquid out of the tank, pressure must be built up. Room is left within the tank for air, which is pressurised prior to spraying. The difference between tank size and working capacity is to allow for this.

When buying a sprayer, it is worth considering the fact that more pressurised air within a tank (or a greater difference between tank size and working capacity) means longer spray time before one must stop and re-pressurise the tank.

It is also crucial to know the working capacity of a sprayer, not just the tank size, as this is the maximum level to which the tank can be filled and still function properly.

As each manufacturer of spraying equipment tends to have different threads and sizes, there is no guarantee that the 5.4-metre or 3.2-metre telescopic lances will fit any sprayer on the market.

The lances will fit all of our GOIZPER and IK sprayers as well as our electric rechargeable sprayer and Mesto sprayers however, the lances will require a connecting hose if being used with our Mesto sprayers or rechargeable sprayer. We recommend that you purchase a bundle with the lance which includes a hood and a directional tube with the connecting tube.

The pressure needed when spraying a liquid depends upon the product being sprayed and the circumstances in which the sprayer is used.

Many commonly used domestic products will not require a high pressure sprayer, perhaps only 3 BAR or even 1.5 BAR. However, thicker liquids will require more pressure.

Just because a sprayer can work up to a certain pressure, this does not mean that it must be used at that pressure. Some of our sprayers are fitted with specialist pressure gauges, allowing the user to choose the pressure that best suits them and the ideal pressure for the product being used.
