Large disposable caulking sticks, 50 to a pack. The flexible stick tools a bead in a gap too tight for a blade, and it throws away after, so silicone never meets acrylic on the same tool.
Big pack, big jobs: no stopping mid-run to wash tools.
Flexible tips tool beads in gaps blades cannot reach.
Single use: no cross-contamination between sealant types.
50-pack covers big sealing runs without stops.
Lay the bead slightly proud, then shape it with the stick in one pass while the sealant is wet. Bin the stick when the tip builds up. Keep a handful in the tube for each sealant colour on the job.
For finishing wet sealant, not removal. A stick cannot replace a blade profile on long, straight visible joints.
