This is a follow up post on removing the smell of dog wee from artificial grass. I discussed last year all the products I have tested so far and the ones I feel work the best. I will now introduce you to the best way to remove odour from artificial grass in 2021.
I always want to find the answer to any problems I may encounter with artificial grass so that I can try to develop our products.
I still do not believe that the smell of dog urine in the warmer months is anything to do with the groundworks (as long as the membrane is below the aggregates the urine will naturally pass through the layers of granite dust and Type One). Hosing down the grass every now and again will help with this as will rain.
As previously mentioned I will continue to use our own Dog Wee product (a fine sand top dress) brushed in to the artificial grass, which holds on to the ammonia in the urine. This works to an extent, however I am looking to take it a step further and try and totally eliminate any odours.
Odour coming from grass not the aggregate
My dogs love to wee in the corner of my garden against a pot. I have folded the grass back in this location as you can see in the photos below and on very close inspection (not for the feint hearted) I conducted a Sniff test. It was quite clear that there was zero odour coming from the aggregate on the left, however the grass in the right hand photo quite clearly had a smell!
So to me this means the issue is 100% a grass and not a base issue.
Aggregates with no odour
Grass with an odour
New PU coated backing on artificial grass
As I believe it is a grass issue I have developed two new artificial grass products with a PU coated backing. These are the Spring 30 and the Olive 30 grasses. The PU or polyurathane backing does not absorb moisture and therefore won’t absorb the urine. This will prevent any odour build up. These products replace two previous versions that had a latex backing which absorbed moisture creating the smell. Because the grass fibres are also non-absorbent then the urine should easily be washed away.

New non absorbent PU backed grass
Applying an absorbent mineral
In addition to the PU backing I am testing a new absorbent mineral called Zeolite. It is a crushed natural mineral which I hope will absorb any remaining odours. The idea of the top dressing is to lock onto the ammonia and absorb it, without giving off an odour until the rains come and washes it through. Zeolite is nontoxic to people and animals and is environmentally friendly which makes it an ideal substance for pet owners.

Refreshing this particular artificial grass lawn
To refresh this lawn I added a little extra granite dust and re-screeded the corner before re-fixing the grass to the timbers. I then raised the grass fibres with a power brush to get the Zeolite into the pile. See the full details of how I applied the Zeofill to the lawn.
I will keep you posted on this and if it is a success I will pursue this with all our dog installs!
