Azpects EASYSeal Sandstone Enhancer and Sealer 5L 
From marking out a road or a car park spot at a warehouse, Everbuild's trafficline spray is a great way to cement directions on a surface.
Can I mark a tennis court with trafficline spray?
Whilst the name suggests cars and roads, the trafficline in fact can be used on a tennis court. It comes in a white variation making it perfect for a green or blue surface requiring clear guidelines to set up a professional tennis court. Moreover, it can also be used on concrete basketball courts, and sports halls when you want to play some badminton.
How to use trafficline spray?
This product doesn't require expertise. Any. To use it, you simply have to shake it, and then shake it some more for around 2 to 3 minutes. After it's ready, you simply spray it on the surface and leave it to dry for at least two hours (to be safe). If it's raining or about to rain (within 1 hour) then don't use this product -- wait for dry weather.
Which colours mean what?
Typically, white suggests general marking (arrows, parking bays, outlines of a court). On the other hand, yellow is a bit more cautious and represents potential places of hazards. Lastly, we have red. As you can imagine, it represents danger and prohibited spaces.
