DAP Alex Fast Dry Acrylic Latex Caulk, 300 mL White — Paintable in 20 Minutes

On a paint day the caulk is the bottleneck, which is the whole reason a fast dry acrylic latex caulk exists: a standard latex bead holds the wall hostage while it skins. DAP Alex Fast Dry is tack-free in about 15 minutes, ready for a brush or roller at 20, and sprayable the moment it is tooled. A painter can run the trim, come back around the room, and start cutting in without a second trip. It is the same siliconized acrylic chemistry as the rest of the Alex line, so the bead stays flexible and resists the cracking and chalking that opens a hairline along casing a year on, and it will not shine through or discolour the coat that goes over it. It grips wood, drywall, plaster, vinyl, aluminium, brick, stone, concrete, fibre cement and stucco, inside or out, and washes off hands and tools with warm soapy water. Joints up to 9 mm take it neat; anything deeper wants backer rod first. For trim work on a schedule, this is the tube that keeps the day moving.
