A guide to removing playground markings.
The time will come when those markings you had installed ‘a long time ago’ have become faded. There are a number of options available when it comes to getting your school playground back to a good condition.
Option 1. Ignore the old marking and have new installed on top.
The cheapest option but not always a viable one depending on how faded the old markings have become. The eye is always drawn to bright colours and as such, new markings will distract the eye, with the end result being that new markings will be seen quickly and the old markings fade into the background.
It is sometimes possible to install new markings on top of old, depending on the condition of the thermoplastic below. Essentially there is little benefit to be had from installing new on top of old playground markings if the old markings are going to lose their grip on the playground.
Option 2. Have the old markings removed.
When it comes to removing playground markings there are a couple of options available. Please be aware that all of the removal processes will leave a very clean area where the thermoplastic playground markings / painted markings were. This will blend back in with the playground as it naturally picks up debris.
Sand Jet Cleaning.
The low pressure sand jet is different from other line removing technologies being totally environmentally friendly as it uses no toxic slurries and generates no fumes. It has a low consumption and hence creates little mess, and it is quick, compact and clean enough to not require elaborate barricades to protect the public (footpaths do not require closing). The system also does not cause surface damage and it is highly mobile.
While we cannot compete with the speed of the more powerful burning systems for line removal, we do not leave melted tarmac or residue, and do not generate black smoke. Our only residue is a little sand, water and the line material, which can be washed or vacuumed away.
Sand Jet removal of playground markings is ideal for delicate surfaces but does take longer than UHP cleaning (see below).
Ultra High Pressure Water Jet.
A more aggressive clean that intensely cleans the surface of the playground. Please note that UHP cleaning typically leaves a clean ‘mark’ on the playground surface as it utilises a higher pressure than sand jet cleaning. This will fade over time as it naturally picks up dirt / debris and blends into the playground.
Access to the playground is ideal as is a dependable water source (outside water tape with normal pressure is normally fine).
