ABSTRACT:
A grout sealant applicator for holding a quantity of low viscosity liquid grout sealant and for controlling the uniform rate of dispensing the sealant into the groove of the grout of a tile floor. The applicator includes an elongated tubular handle which is fillable from one end with sealant and a sealant flow regulating valve at the other end of the handle. A nozzle is connected to the valve so that sealant flows by gravity feed from the handle when positioned somewhat uprightly, through the valve and a small longitudinal bore within the nozzle. The handle is of sufficient length to hold a large quantity of sealant to minimize refills and to permit the hand grasping and manipulating of the upper end thereof to cause the distal end of the nozzle to slide within the grooves formed by the grout and without the need for stooping or kneeling. Sealant flow regulation is also controlled by providing a removable end cap at the upper in use end of the handle having a vent hole which may be closed by a finger or thumb of the user to prevent air from entering the handle. A tubular handle extension, transparency of the handle for sealant level viewing, and a shaped nozzle distal end conforming generally to the concave grout are also provided.
