Sealing around your basin and vanity isn’t just about looks—it’s about protecting your bathroom from water damage and mould. Whether you’re doing a new installation or refreshing old sealant, this simple task can make a big difference in your bathroom’s durability. If you’re in Mulgrave, Melbourne, Victoria, or anywhere in Australia, here’s how to seal like a pro.
Why Sealing Is Important
Water can easily seep into the gaps between your basin, vanity, and wall, leading to mould growth, damage to cabinetry, and costly repairs. A neat, waterproof seal keeps your bathroom hygienic, looking fresh, and functioning well.
Tools and Materials You’ll Need
- Silicone sealant (waterproof and mould-resistant)
- Caulking gun
- Masking tape
- Utility knife
- Cleaning cloth
- Mild detergent or rubbing alcohol
- Bowl of soapy water
- Smoothing tool or your finger (with gloves)
Step-by-Step Guide
1. Remove Old Sealant
Use a utility knife or sealant remover to carefully cut away old silicone. Be gentle to avoid scratching your basin or vanity.
2. Clean the Area
Wipe down the surfaces with mild detergent or rubbing alcohol to remove dust, soap scum, and grease. Allow to dry completely before applying new sealant.
3. Apply Masking Tape
Place masking tape along both sides of the joint where the sealant will go. This helps create a clean, professional finish.
4. Apply the Sealant
Cut the tip of the silicone nozzle at a 45-degree angle. Load it into the caulking gun and apply steady, even pressure as you run the sealant along the gap.
5. Smooth the Sealant
Dip your finger (wearing gloves) or a smoothing tool in soapy water, then glide it along the bead to create a neat finish. Remove masking tape before the silicone dries.
6. Let It Cure
Check the sealant packaging for curing times. Most silicones require at least 24 hours before coming into contact with water.
Pro Tips for a Perfect Seal
- Use a high-quality silicone for bathrooms—look for labels that say “mould-resistant” or “kitchen & bath.”
- Work in small sections to avoid the sealant drying before you smooth it out.
- Replace seals every few years or if you notice cracks or discolouration.
