The CUSTOM BLDG PRODUCTS PC6010S-6 is a siliconized acrylic caulk formulated to match Polyblend grout colors in residential interior applications. This sanded caulk ships as a 6-pack of 10.5 oz cartridges in Charcoal (color 60), giving tile contractors and plumbers a color-consistent seal at movement joints where standard grout would crack. The siliconized acrylic formula delivers flexibility and adhesion at transitions between tile and dissimilar surfaces such as tubs, sinks, and shower surrounds. Built-in Moldgard technology inhibits mold and mildew growth in consistently wet environments. Interior use only.
This caulk is intended for interior wet-area installations including showers, bathtub surrounds, kitchen sinks, and countertop-to-tile transitions. It is designed specifically to complement sanded Polyblend grout installations where the grout line color must carry through to the caulk joint at changes of plane — floor-to-wall corners, wall-to-fixture edges, and similar locations. Tile setters, plumbers, and finish carpenters working on residential bathroom and kitchen remodels are the primary installers. Each 10.5 oz cartridge fits a standard caulk gun.
Formulated to color-match Polyblend sanded grout for interior ceramic tile installations at showers, tubs, sinks, and tile-to-surface transitions.
This product is typically applied by tile setters, plumbers, or finish contractors during the final stage of a tile installation. Before applying, ensure the substrate and surrounding surfaces are clean, dry, and free of old caulk, soap residue, and loose material. Apply in a continuous bead and tool immediately for proper adhesion and a clean joint line. Allow full cure before exposing the joint to water — consult the product label for cure time before wetting.
