Bio-Shield® Reviews
I did my stenciled driveway at the beginning of summer which had a lot of black mold after several months and good follow up rain cleaner has worked a treat and now I have a clean driveway. I have purchased more to do the driveway pavement again next summer. Thanks for a good product

It's working We have Gerard stone chip tiles on the roof and plenty of lichen stuck to them. I did not want to pressure clean because of the stone chips and saw Bio-Shield advert. and decided to try. I used the spray attachment and wet the roof as per instructions in February. We thought some lichen had gone when we have looked at the roof over the last few weeks, but last night there was heavy rain and looking this morning (April) most has gone. Still some on the southern side that is shaded. Our back patio that has colorbond roof and was completely covered in lichen is now clear after the rain. I will wait until next summer and see if the rest of the tiles are clean or if the lichen is gripping to stone chips. If necessary I will spray again, so easy.

Don't Hesitate to Get Bioshield - It's a Beauty! Incredible product. Use it on just about everything outdoors, and even indoors wherever there is mould and mildew. Wish I'd used it years ago instead of pressure cleaning.now and always had good results

Thank you excellent delivery as always, now I have no excuse to start Spring cleanup. Love this product and have recommended to others who have also found it great. Hope this time the hose bottle will make it even easier.

We’ve been using Bio Shield for a few years with great results controlling the lichen build up on our roof tiles. It’s a great product. It’s good to know there’s companies out there that actually deliver on their promises.

Spray it on and let Mother Nature do the cleaning. All of our sandstone retaining walls are just like they were newly installed. The lichen on our glazed terracotta roof is nearly all gone (just need another spray next month). Brilliant product, thanks Andy.

Hi, bought this product in 2019 to clean Polycarbonate roof, absolutely brilliant, time to redo. Thanks for a great product.

We had a large coverage of lichen on our skylights in the fernery, looking from underneath it was terrible. We followed your instructions and applied the Bio-shield - being sceptical that it would work. Applied the two coats and then washed it off. To our surprise it just fell off and a clean surface shone before our eyes.

Bio-shield delivered this morning. Have used this product in the past with great results. Thanks for the prompt follow up of the original order.

Our clay tile roof was infested with moss and lichen. We attempted to clean it with a pressure washer but there was a significant risk of water ingress and so we stopped. A couple of years later, 2020, we tried again but this time with the Bio-Shield product. there was a small improvement. We sprayed again about 6 months later. There seemed to be some improvement and so we arranged to spray again. The roof was first blown and then the roof looked almost new. We will repeat regularly.

It's not often that a product lives up to the manufacturers advertising. All I can say is that i had my doubts after applying 2 other types of lichen removal products to my lichen covered colourbond roof which had limited affects. I applied bioshield as per instructions and nothing happened for a few weeks but now after several months my roof is completely free from lichen . I'm amazed.! Excellent product and it was delivered within 2 days after ordering

Just a short note to thank you for your prompt service. An order placed on Sunday delivered to my door by DHL at lunchtime on Wednesday. Unbelievable service from NZ to Australia in 3 days. Arriving on the date promised

Bio-Shield worked so well on our home that we are now going to use it for our local community hall.

Just wanted to say how thorougly impressed I am with Bio-Shield. All the claims you make on your website are true. The product works great. The Jet-Stream is a real time saver. The only thing more impressive than the product is the delivery. Only days to deliver from NZ to North Queensland. Don't normally write this sort of stuff, but was compelled by the quality of product and service.

Our tiled roof had a lot of black mould area's making it look terrible. We researched Bio-Sheild and decided to give it a try. It's done wonders over the past few months!!! So glad we tried it. It was easy to order and arrived promptly. We are very happy customers. Thanks Andy!"

Just to thank you for the moss remover; I have already been up on the roof (not bad for an 86 years old) and was very impressed as to how the attachment spray worked. I completed about half the roof in about twenty minutes. I have enough spray left to do another part of the roof when the weather get a bit cooler. Once again many thanks.

I was concerned at a lack of progress, I really was. But 8 months later, my terracotta tile roof looks brilliant. Well done. Good product, good value.

G'day, Just thought I'd send you a couple of pictures of how well your product worked on my tile roof. We are very pleased with the result as you will tell from the pictures and have had no problems recommending it to our friends. The before pictures were taken on the 29-7-15 and after 19-3-16 All i did was mix it up and spray it on.
Thanks for the great product.
