COMPARISON
Self-leveling underlayments and floor patches compared by walk-on time
59 products in our catalog state a time for light foot traffic, from 15 minutes (ARDEX Feather Finish) to 2 days (Sika Sikafloor-315 N). The median is 4 hours. The table shows the 20 shortest, built only from numeric times in manufacturer documents.
Fair-comparison rule: Read the exact milestone and conditions on each product page. Similar numbers can describe different tests, substrates or stages, and a faster time is not automatically a better product.
