Not useful at all. Left it for 15 mins, 30 mins, 45 mins, does not do anything to my tiles. Tiles still slippery after that.
Tested the non slip product on my toilet floor. Follow the instructions and after 15 mins clean the area and yes the floor is not slippery at all. For a 30ml non slip will be just sufficient for 2 toilet in a HDB flat. Will need to monitor and see how long the product will lasts.
Ordered on Sun night, received on following Sat morning, it take about 1 week to deliver and no bubble wrap protect.
