TEC 820 Standard Gray Unsanded Caulk

TEC 820 unsanded caulk in Standard Gray is the color-matched sealant for the joints grout can't handle. Changes of plane — inside corners, where the wall meets the floor, around tubs, sinks, and countertops — expand and contract, so rigid grout cracks there. Flexible caulk moves with the joint and keeps the line clean — the finishing step that separates a pro install from a callback.

Use it on narrow, unsanded grout joints where you want a smooth, sand-free finish, whether you're a DIYer or a working contractor. Standard Gray is formulated to coordinate with TEC grout, so your caulked corners blend with the rest of your grout lines instead of standing out. Tool it with a wet finger or a caulk tool for a tight, even bead.

Pros trust TEC for consistent color and easy tooling, and we stock TEC 820 Standard Gray at Tile Outlets so your caulk matches the job.
