This was a very large decking that we cleaned last year but due to the weather and time of year we could not get to treat it.
We returned this year to clean it again and this time we will be treating it.
Due to the very large number of VERY large trees that cover and surround the decking it becomes VERY dirty and covered in sap.
It took a long time but as you can see it came up a treat and this is before we have treated it.
Large jobs like this take time folks and do not be fooled into thinking otherwise for best results!
