Very pleased,


Tried other products with varying amounts of success so having tried other Smartseal products thought I'd give this a go, as always Smartseal delivered. Killed the moss and made it easy to get the drive cleaned and re sealed.

By Alan Setterfield

The moss clear is an excellent product which I have used successfully on drives, roofs and fences.

By Duncan Goodwin

Brilliant product cleared moss and algae from my path and drive within a few days.

By Robert Beatson From North Somerset

Excellent product for moss, great service from Dawn, thank you, outstanding.

By Robert Jarvis From Birmingham

Excellent product, doing just what it says on the tin.

By David Borthwick

Fabulous for clearing moss from a tarmac drive and also from paving stones

By Clive Bramley

Followed the instructions carefully and it has done the job well. Drive was well prepared for the application of the restorer. Need to be patient......allow several days for the product to fully work. I was able to use the left overs to spray the moss on the roof too! I will certainly be repeating the application from time to time to keep the driveway clear.

By Neil Underwood

Thank you for helping me with the moss problem. The customer service was top class.

By Rosemary Hopkins From Harlow

Service excellent goods delivered quickly. However, unable to comment on product not used.

By Ian Brogden

Didn't remove the moss just discoloured it, disappointing

By neil sellick

Weather conditions have not been conducive for me to use the product since receiving it, however SmartSeal deserves real credit for their speed of service - the 25-litre product was ordered on a Sunday afternoon & arrived first thing the following Tuesday. Impressive.

By David Thompson

Excellent does exactly what it says it does and works very quickly

By Gail Ashton

Worked like a treat. Killed all the green slime on our natural paving slabs very quickly & almost all the moss...a few areas needed a second treatment but very pleased with this.

By Sue Rowland

Excellent product. Sprayed the roof of our bungalow, killed all the moss in about a week. Just need to brush it off now.

By Jeanette Hand

We have used this product several times now on our customers drives and after two coats on 20 year old blocks it does look like you have just laid a new drive . Would definitely recommend.

By Mark Garside

One word Brilliant

By Kevin Farmer

First time using this product does what it states very pleased with the result.

By Brian From East Cowes Isles of Wight

Yes! it has done what it says on the can. I have used it on my block paving which was only lightly infected by moss and it appears to be working well. I have also applied it to my roof which is of cement tiles which was very much infected by moss, the moss has after 3 days turned a yellow colour and I am just waiting for this to fall away. I'm hoping for the best on this.

By Vernon Nuttall From Thornton-Cleveleys

The best Moss treatment product on the market in our opinion. Makes our life easier when dealing with a moss covered surface as a pre-treatment.

By David Leopold From Ultimate Cleaning Solutions

Wow what an amazing product!!! I recently had 90m of sandstone pavers laid, I sealed them straight away with Smartseal sealer but to my horror they were going green with 3mths. I tried jet washing them but the green still didnt come off. A call to smartseal customer services for advice ended with them sending me a sample bottle of their Moss Clear product due to the amount of Paver seal I had previously bought. I was not confident it would work as all you have to do is mix the Moss Clear to the desired strength (I used 3 parts water to 1 part moss clear) then pour it over the affected area and let nature take it course. Well even by the next morning the results were evident, now the whole 90m looks like new again, an amazing product that really really does work wonders. Many thanks.

By Jig From West Lothian

Used MOSS CLEAR at lot,on all different roof types, very good product Delivery always on time and as for help and support well what can I say FIRST CLASS !!


Good product - The moss was thick on our stone slabs, and it is clearly dying after 3 days. Delivery was good, well packaged and on time, but a little expensive.

By Nuki From Mansfield

Does exactly what it says.....and no more: I was amazed to see that tufts of grass survived, but the moss and algae were totally zapped.

By Ally From Midlands

Good product, good price (apart from postage) prompt service. Have a tarmac drive and has done the job well so I can recomend Moss Clear and SmartSeal ... will be visiting you again when the dreded Moss returns!

By Gareth Hughes From Pembrokeshire

Used product on north facing block paved driveway. Varying degrees of algae depending where the sun shines. So, I applied with a watering can 5:1. In the lighter areas the algae disapeared as it dried! In the heaviest areas the area was clear in three days. Very impressed with product and service have ordred more for next time.

By Stuart Biggs From Stuart Biggs

Arrived withing 3 days as promised, technical help second to none, applied one coat with sprayer tonight, hopefully in a few days the area will be ready to be washed.

Moss Clear is a biocide that will remove moss, algae, fungi and other types of organic growth. As a moss remover Moss Clear is suitable for block paving, concrete, tarmac, decking, roof tiles and many other external hard surfaces.

Moss Clear is a new roof cleaning and paving cleaning concentrate. It is formulated as a moss, mould and algae treatment that safely removes all types of moss growth from paving. There is no need for washing off at high pressure or scrubbing. By reducing the pressure whilst cleaning the risk of damage to roof tiles is minimised and cleaning time reduced. The moss killer branded as Moss Clear is also a moss inhibitor. It can be applied after the roof has been cleaned to eliminate the risk of moss and algae spores re-forming.

We also recommend Moss Clear as a moss killer for use on paving, tarmac and other concrete surfaces.


For best results dilute at a ratio of one part moss clear to five parts water.

Coverage of approx 100m2 to 125m2 can be expected from 5 litres of moss clear. Application by sprayer or watering can is recommended.

Moss clear, once dry, is a safe and non-hazardous product. Moss Clear is made from biodegradable ingredients and does not include any bleach or acid contents.
