we droped a bit of a clanger with the work we did ,it was the areas surrounding play areas that is made of rubber that we cleaned, it was covered in green and very slippy there was about 170 square yards and thought it would only take about two and half hours but the flat surface cleaner wouldnt touch it so had to do it all with the lance ended up taking 2 of us 5 hours and £40 in diesel for a £240 job so be careful if you ever have to price to clean any of this rubber surface material its a real swine to do.
