This is good stuff- started to kill moss within a couple of days of application. Not the cheapest on the market but certainly one of the best. I have tried other cheaper brands & also bleach to no or very little effect.So you get what you pay For

I agree with other reviewers that it should be made far clearer that the product should be used within 3 months once opened.I also found that re-treatment was necessary which therefore greatly reduced the effective coverage. That said, the end result on my patio was really good and I will use the product again.

Ordered product the second time and it didn't disappoint, works fast and removes even thicker moss without problems. Had about 2 litres leftover from last year and it still worked and now 6 months later still no moss growing.

My husband sprayed the roof today, having had to wait for a still day. The instructions are very clear and easy to follow. He used your product a few years ago and it worked really well. It has kept the roof clear of moss and today's application was mainly as a prevention. WE have every confidence in your product. Thank you.

Great product, good instructions and yes the user guide does state once opened use within 3 months. That said if you weigh up the cost of 5 litres, and any wastage thereof at 7 per litre against getting a roof cleaning firm in, the overall savings make it a non brainer. Best of all, staff are available to help and advise and in my case prevented me from ordering the wrong product for my roof. Well recommended thank you

MossClear Pro is an excellent moss killer and 5 litres will go a long way. Unfortunately, the user guide on the 5-litre container states that once opened the product should be used within three months. This is certainly not made clear from the SmartSeal website and can lead to a lot of waste unless its usage can be planned out from the start. The roof on my semi only required two litres of product and am not sure how active the product will be for next years application.

Very good, diluted as instructed, very clever, within 7 days the dirt, algae and moss just lifted without any need for further cleaning. Simple and effective.

Smartseal is a excellent product & killed all my moss on my tarmac drive.

Found that this treatment was not effectice on moss (on tarmac) that had died and gone brown. Had to be scraped off.

Great , did the job I ordered it for. Would order from this company again. Slight hiccup with delivery due to this virus, but expected that Would recommend the Moss Killer liquid.

I have used many Smartseal products for a few years and they are excellent at what they do. The firm is always helpful with technical enquiries and the delivery is sound. The Moss Clear is great on roofs and the natural stone sealer gives a great finish. You can really see the difference and it lasts for a few years. Good stuff

By Donald Johnston

Absolutely fantastic product. I found the product due to looking of the internet.....and I'm pleased I did. I now wont use anything else to remove moss and keep it at bay. It really is a great product, easy to apply and does the job.....couldn't ask for anything better. Highly recommend it if you are looking for moss killer that is effective

Moss Clear- Does what it says on the bottle.

StarStarStarStarStar
By Peter Sellors

We were plagued by moss on our three year old tarmac drive and had tried pressure washing with poor results. So we thought we'd try chemical treatment and found Moss clear online at Smartseal. Delivery was pretty quick. I have to say that it is now eight bone dry days since we applied it diluted 1 to 4 with water using a stiff yard brush and it definitely looks like it has worked. Many of the previously green patches have now turned brown while others less populated look completely clear. I'm waiting for the expected rain to clean the residue but if we get none soon I'll get the washer on it again. I'm very happy with the result.

The moss clear pro worked well except for the blacker areas on monoblock. But they have faded so it may be too soon to tell if fully successful. Will buy again.

Killed the heavy Moss on my house roof after two applications. I was unable to remove the surface moss first. I am happy with the result and I used concentrations of 4:1 water/concentrate.

Seems a very good product although time will tell. I did srap off the bulk of the moss before the Moss Clear Pro was applied. Haven't got any photos though as forgot to take some before. It will be interesting to compare as used another product on two other houses in the same cul-de-sac about 4 years ago and both of those roofs still really stand out from the rest so i am hoping this one will be the same.

Very happy with this. My patio was starting to take on a green tint but after one application of this the moss was 99% gone - I just need one more go in the slightly heavier areas.

Great product. Worked on most of the moss on our drive but as it's a big drive we missed a few spots :D

By Barbara C From Berkshire

Best on the market for clearing green algae and moss from roofs. Tried others, but this product is the one i come back to. More expensive on the face of it, but if you do the sums properly, the � per litre actually works out cheaper than other products on the market that have less active ingredients. Just saying!

It's early days but on first application the other day I can see the moss on my driveway changing colour as it dies. Assuming that continues my star rating will go up to a 5.

Brilliant product. Does what it says on the can. Had a heavy amount of moss on the slate roof. This started to show signs of dying just 12 hrs after spraying.

By Gary Quest From Devon

Used Moss Clear Pro on my Indian stone driveway to clear the green algae that was forming and making it look unsightly. Used it with a 5 to 1 mix with a pressure sprayer, very easy to apply and within a matter of a day the green algae had gone and the drive looked like new again. Would definitely recommend this product,not cheap but does the job effortlessly.

APPLICATION INSTRUCTIONS:

Shake container well before opening. Add Moss Clear Pro to water in container to avoid excessive foaming and mix well before application. If applying to heavy moss, brush the growth before treatment. For best results it is vital to ensure thorough saturation as some mosses are very compact and it can be difficult to penetrate the stem structure.

A second application is recommended to remove highly resistant plants and lichen as well as dormant spores. This will also help to delay any re-growth of moss. To maintain a problem free surface, re-apply at least once a year. Use a brush and hose to agitate and remove dead spores.

Can be used all year round to eradicate or prevent organic growth - safe for animals & children once dry.
