The crack or crevice to be filled should be cleaned by mechanical means. If required, the crack should be opened in a 'U' shaped groove and cleaned properly to remove loose materials & laitance. Apply a coat of SMACĀ® ELASTOPRIME S primer, which enhances proper bond with the substrate and also penetrates the adjoining area to seal it against water ingress. Fill the crack with help of putty knife and level properly. Wash hands and equipment with soap and water. Let the sealant cure. Touch dry & full curing time at 30o C is about 2 hours at 60% humidity. In rainy seasons, the time required for full curing can be about 8 hours.
