To reseal a bath, remove the failed sealant, prepare a clean and dry joint, apply suitable bathroom silicone and leave it to cure for the product’s stated time. Use this hour to learn the process and check your materials. Removal, drying and curing can make the full job longer than an hour.
Before you start resealing a bath
Check for a loose bath, damaged surfaces or an active leak first; a fresh surface bead does not repair those faults. Mould on a bead alone does not prove that water has reached the floor. Read the sealant instructions for compatibility with your bath, tiles or stone, required joint size and when the bath can be used again.
Use a suitable removal tool without scratching the bath. Follow cleaner instructions, ventilate the room and do not mix cleaning products. Remove residue and let the joint dry before applying silicone. Follow the bath and sealant manufacturer’s instructions about loading the bath during application. Tool the bead within the stated working time, then keep it dry for the full cure period.
Why learn to re-seal a bath or sink is worth an hour
