A gasket is provided for creating a seal between two surfaces. The gasket may include a pervious base sheet and a permeating material applied to or incorporated into the base sheet. The gasket is formed by various methods disclosed herein. The gasket may include a base sheet, a primary sealing material covering and/or impregnated the base sheet, and a secondary sealing material covering the primary sealing material. The secondary material may be applied in a predetermined pattern of raised and lowered sections or may be applied as a bead of sealing material. The secondary material may be applied through a variety of techniques including jetting and dispensing using robots such that beads with custom engineered and changing configurations along their lengths are possible. These custom engineered sealing beads provide optimum sealability over the entire area of a joint to be sealed. |
