Temporary game line tape is NEVER RECOMMENDED on sports floors coated with polyurethane, as there is a high risk of delaminating the finish from the floor when removing the tape. However, if tape must be used, use it at your own risk and follow these procedures to minimize damage:
- The finish on the floor must be cured for at least 30 days.
- Use only lightweight tapes that are easy to remove (3M brand 2080 & 2090).
- Do not leave the tape on the floor longer than 24 hours.
Water-based tempura paint can also be used to create temporary lines (see warning below). The finish should be cured for a minimum of 30 days before using these paints. Test the paint first by applying it to a small, inconspicuous area. Allow that paint to dry completely, then remove it with a small amount of warm, soapy water on a rag or sponge. If the paint removes easily and completely, then apply it to the remainder of the floor as game lines.
WARNING 1. Tempura paints can sometimes attack and dull the sheen of the finish. These paints should be removed as soon as possible. Be sure to test the paint before using. 2. Use only white tempura paint. Other colors can bleed into the finish.
