Bio-Shield - Exterior Cleaner for Moss, Lichen Removal & Concrete Cleaning, from just 94c Lt

Have found Bio-Shield works really well on Nostoc Commune. A real snotty type algae that seems to grow on metal/stone driveways.

Tried Bioshield after using wet and forget. Bioshield so much better value for money and does the same thing. It does take 3-4 months to work, patience is key! Will only purchase Bioshield from now on. Thanks!

Ordered twice. 1st time No packaging at all. Both times delivered to wrong place. Second time product "disappeared". Supplier very unhelpful and would not refund or replace product. There is indeed no f in customer service here

Have only used a little but it seems to have worked ok. A bit fiddly with pouring out of container (need a funnel or similar). Would be nice to have it in a bottle and ready for spraying (with hose connector) for rapid application - similar to competitor's product. Will edit review once I do the whole drive/walkway.

Used some more a couple of weeks later to do the rest and used another product applicator as opposed to mixing into a garden sprayer. Worked great and so far, it looks like its doing what it's meant to do. Haven't got a lot of surface area to cover, the reason I did not buy the 7.5l combination that included the applicator. So far, so good but it has a feel of value for money compared to the other product I used at our other house.

Had the moss build up on my asphalt roof tiles cleaned in June but frankly I'm unsure whether it was a good idea. Soon after the roof leaked badly and a roof repair company advised because of the timing of the cleaning & the leaking, the cause was most likely caused by chemicals partly breaking down the sealant adhering the shingles. The roof repair company had seen this exact same problem before. In future they informed me of an alternative less harmful application to use with a water wash off at the end of the process. Obviously Bio is a good product to use on other surfaces but not on asphalt roofing tiles.

This product has been the best product for removing lichen and other associated spores that I have purchased, I have tried all the other television advertised products and they dont come near this product. Highly recommend it. It starts acting almost straight away.

Awesome product recommend to anyone looking for a product thar cleans moss, fungi off loved ones headstones. Andy was helpful and easy to communicate.

Fast prompt service, product arrived in christchurch the next morning allowing me to get the job done! Cheers Wardy

Fantastic product at reasonable price. There is tremendous opportunity to market this product in India. I spent at least 3 hrs on net to locate nearby supplier in Gujarat state but failed to find anyone. My house wall is gone black with mould. Lots of houses around my house have the similar problems but no one seem to know how easy it is to get it cleaned! Let’s move it India! I guarantee 100% success Harish Wellington

Great product, have been using it for 4 years now and my concrete driveway and pathways have never looked better. No need for a heavy water blasting any longer just an occasional light hose down with a re-application of bio-shield every other year. Andy is a great guy to deal with also, he is very friendly and helpful with his advice and knowledge and his service is second to none.

Great service under covid restrictions. Very prompt and efficient service/delivery. Stars above are for the service as i have as yet not used the product. So saying if the product is as good as the service/delivery then it should be great

Excellent product which is easy to apply and really works plus great customer service. Alison - Hamilton NZ

These guys are brilliant. Ordered some of there product during lockdown at about 1.30pm on Friday and it was delivered at 9.15am Saturday morning to Hamilton.

Great product and very easy to use with the spray on applicator.
Also a great price. Delivery was the next day Great service This has been my 3rd 20litre order over the last 4 years
Thank you.

Excellent Service Product Arrived Quickly - Used on Large Heavy Shade Cloth Curtains Enclosing Deck Sprayed Both Sides rained next day they are back to origional Cream Colour. No harsh chemical smells. Would definately recommend

Great product used it successfully for years and only once when I had a minor concern the company (Andy) sorted the problem out immediately.
Would highly recommend, I also find Bio Shield much better value for money than other overpriced moss / lichen cleaning products constantly advertising themselves with saturation marketing.

Hello All, this product is amazing YES you may think it is a tad expensive but the result is well worth it, I would never use anything else well done Bio Shield

Great product. Highly recommended. Can do larger area for less amount of BIO-SHEILD. Much better than all other over priced products I have used. Could see the effect of the product on moss and lichen on all my concrete and paved areas the very next day. Very effective when applied late in the afternoon when it's not sunny. Also very professional company to deal with and good advice from Andy. Was delivered in 2 days.

Don't waste your time on this product, it's not worth it. We tried it but must say terrible product, bought Wet and Forget and solved our issue with roof and deck.

Very professional company to deal with, ordered from Auckland and received in Levin in less than 24hours, totally hassle free. Look forward to trying your product. Thanks guys, you are brilliant. THANK YOU
