Playground Marking Removal
Removing playground markings currently takes up about 30% of our time. Nearly all of it in the school holidays or at weekends. Most of the schools seem to be in Yorkshire, Lancashire, North West or South West England or in the London area (partly because we are generally contracted to companies who are installing new markings – who are based in or marketing to these regions), but we have undertaken work in Scotland and Wales as well.
We specialise in using a low pressure sand jetting system. This ‘damp’ system captures line marking material, dirt and abrasive, preventing the health and safety risks associated with dry sandblasting, and with none of the toxic fumes and thick smoke of burning the material off. We can also offer Ultra High Pressure Water blasting line marking removal. For speed, UHP water jet removal is probably the route forward
For Cost , or accuracy.. and for small jobs the Sand Jet wins. Most playground fall into the sand jet camp – but the cut off is about 3 days removal work where the time / speed of the sand jet starts getting overtaken by the speed of UHP… that being said, there are also many instances of the playground tarmac being in such poor condition that Sand Jet is the only way to go.
Sand Jet Marking Removal
We use our sand jetting system for most of our playground work. This ‘damp’ system captures line marking material and generates no toxic fumes and thick smoke of burning the material off.
The Sand jet safely removes thermoplastic or other paints from almost any surface – concrete slabs, block paving, tarmac – and is accurate to about 1/4″ so, for instance we can do removals of old marks from around new.
UHP Marking Removal
Ultra high pressure line removal is rapid, perhaps 10 times faster than the sand jet – particularly for thick thermoplastic. It is however more aggressive on the underlying surface – and care must be taken not to use it on a poor quality tarmac (for example). The cutting face is generally about 20cm wide – and is invisible to the user, so we can’t be as accurate with it as with the sand jet – and typically may have to go over surfaces more than once. One other advantage though is that it creates less mess, and is intrinsically more safe and makes less noise than the sand jet – so this system is more possible to use during school hours. Oh… it does rely on a good water supply as well!
Road Marking Removal
We specialise in using a low pressure sand jetting system. This ‘damp’ system captures line marking material, dirt and abrasive, preventing the health and safety risks associated with dry blasting, and with none of the toxic fumes and thick smoke of burning the material off. We can also offer Ultra High Pressure Water blasting line marking removal. For speed, UHP water jet removal is probably the route forward. For cost and for small jobs the Sand Jet wins.
For accuracy and delicacy – the Sand jet is extremely effective. UHP is something of a blunt instrument – particularly as the work face can’t be seen – and the ‘cut’ is typically 20cm wide. This does mean that the sand jet can remove one set of overlapping markings, and leave the other set intact.
Ultra High Pressure Water (UHP) Road Marking Removal
For Speed UHP is a winner – more or less eating a 20cm wide strip of thermoplastic at ‘slow walking pace’. although it can be something of a blunt instrument – particularly as the workface can’t be seen – and the ‘cut’ is typically 20cm wide. The sand jet on the other hand can remove one set of overlapping markings, and leave the other set intact. The disadvantage of the sand jet is that sand debris is spread over the area – and needs cleaning up – where as the UHP machine just leaves a little shredded thermoplastic.
