Abstract: A nozzle for applying filler material within a groove is provided that includes a plate member, an orifice through the plate member, a guide member for engaging the groove, and a pliable attachment. The orifice is in communication with a supply of the filler material. The guide member protrudes from the plate member and has a width less than the groove. The pliable attachment has a channel with an angled portion for directing the filler material into the groove. The nozzle may also be used independent from the attachment. Also provided is a method for applying filler material into the spaces between tiles. The method include steps directed to the preparation of the filler material, such as combining a cementitious material with a plasticizer in order to form an admixture that has a viscosity making it suitable for application through the nozzle.
