SculpWood Putty can be applied over the RotFix immediately, or up to 72 hours later without sanding. A wet-on-wet application of the Sculpwood to the RotFix is encouraged to obtain a strong bond. There is, however, no detriment to applying the Sculpwood later in time. If the RotFix has cured longer than 72 hours, degloss the surface with sandpaper or a soft, flexible abrasive pad. Apply fresh Rotfix, followed by the Sculpwood putty.
For more detailed information on the application of the EndRot System, please check out the EndRot Product Sheet.
