What Actually Happens During a Professional Shower Regrouting?
Shower regrouting is one of the most cost-effective ways to revitalize an aging bathroom while safeguarding your home against water leaks. Here is an honest, step-by-step look at how our technicians execute a professional regrout.
1. Step 1: Mechanical Joint Extraction
We do not skim over old grout. Using specialized oscillating tools and diamond-grit cutting blades, we precisely cut out the old, degraded cement to a depth of 3mm to 5mm without chipping delicate tile edges. Learn more on our Melbourne shower regrouting page.
2. Step 2: HEPA Dust and Debris Evacuation
All extracted cement powder and crumbly debris are vacuumed out using industrial HEPA-filtered extractors. This ensures the freshly cut tile channels are clean and ready to receive a secure mechanical bond.
3. Step 3: Biocide Anti-Fungal Treatment
Before applying new grout, we treat the exposed channels with an anti-microbial biocide wash to eradicate any hidden fungal spores that survived behind the old cement.
4. Step 4: Installation of Hydrophobic Polymer Grout
We hand-trowel premium polymer-modified, hydrophobic grout deep into every vertical and horizontal joint. The formulation repels water, resists mould colonization, and flexes with minor structural movement.
5. Step 5: Clean Sponge Profiling and Final Silicone Seal
Our technicians shape smooth, consistent joint lines using damp dense sponges. Finally, we install fresh anti-fungal sanitary silicone along all internal change-of-plane junctions, leaving the shower ready for curing.
