When using tape to mark off gym floors you want to be sure you don't use too aggressive a tape so as to ensure the finish/wax of the gymnasium floor does not come up or is damaged when removing the tape. A vinyl tape such as JVCC V-36 colored vinyl tape or a premium vinyl tape such as JVCC V-36P (if you want the tape to adhere a little longer) would be your two best bets. If you'd rather go with a matte finish tape then a low-adhesion gaffers tape such as Scapa 125 would be another one to look at. Thank you.
