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

Great product on my concrete Pavers.
Pavers had been down for 10 to 12 years, never been touched and mostly in the shade, an old man Totara overhung part.
I sprayed one application last November and am very pleased with result.
Almost like new.
I plan on spraying once a year.

Very good quality product. Have used it in very shaded areas and has prevent moss from returning for 12+ months. It has no bleach in it too which is great. The dilution rates mean a small 5 litre tub makes a huge quantity - other competitor products often have a dilution rate of 1: 1 or 1: 2 which means you end up with a truck load of product stockpiled if you're spraying a decent sized area. This is a huge plus in my opinion.

Prompt efficient service. Ordered Thursday night. Received lower South Island 8am Monday. Thanks.

Some of our Marble Headstones in our cemetery had over 100yrs of mold on them.
Bio-Sheild made light work to bring them back to new.
Would recommend it for any cleaning task

Have been using this product on footpaths, walls and fences and roofs for moss and lichen for nearly 2 years on various properties. Absolutely Fabulous! Friendly efficient customer service and fast easy delivery!

Absolutely love this product. I have used it to restore family headstones that haven't been touched for nigh on 80 years. Highly recommended from me.
Will be using as part of the New Zealand Remembrance Army restoration work too.

Amazing product and fantastic for the NZ war graves project.

You cannot get better!

Bio-Shield has miraculously cleaned our deck with 14 years of accumulated dirt and black algae. With minimal brushing, hosing and leaving it to the weather I have watched it transform from a rather ugly, and slippery deck to a perfectly clean one. Also sprayed a bit of our dome's asphalt shingle roof, with the same amazing result: the shingles look like new. My next job is to do the whole roof: bit worried about the height and sloping sides, but not about the product. Thanks, Andy.

I chose Bio-shield over other brands offered here in Oz and it does a great job and also I can apply it using my Hoselink Fertiliser, pesticide and now Bio-shield concentrate applicator/sprayer.ie no pumping of 5 lt sprayers

Other products are not concentrated enough to be applied by this method. I do a very large area very quickly with minimum effort!

Bio-shield is 3+ times less expensive and delivery is quick.

This is a terrible product, applied to my terracotta roof on approximately 4sq.meters and left it for a week and then used high pressure washer 3000psi and did not come off any easer than the area of the roof that did not have it on. All in all keep away from it unless you want waste your money! The only thing that will remove any growth on a roof is Caustic soda and does not cost an arm and a leg.

Excellent product. Efficient service. Cost effective compared to competitors' products. Recommended!
