COMPARISON
Caulks and sealants compared by full-cure time
84 products in our catalog state a time for full cure, from 40 minutes (Sika Sikacryl PowerSet) to 28 days (MAPEI Mapesil T Plus 100% Silicone Sealant). The median is 2 days. The table shows the 25 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.
