How to Get Rid of Grout on Tiles: A DIY Guide
Learn practical, safe methods to remove grout from tiles, prep for regrouting, and prevent tile damage with our step-by-step guide from Grout Maintenance.
In this guide you'll learn how to get rid of grout on tiles safely and effectively. You'll start by assessing grout and tile types, choose the right removal method, protect surrounding surfaces, then proceed step-by-step to remove grout, clean joints, and prep for new grout or sealing. This approach minimizes tile damage and delivers ready-to-regrout joints.
Understanding why grout removal is necessary
Grout removal is a common step when tiles have become stained, cracked, or moldy, or when you want to refresh a dated look. Simply cleaning grout won’t fix deep discoloration or structural damage in the joints. Removing the compromised grout allows you to reseal and regrout with a clean, even joint that looks fresh and performs better over time. According to Grout Maintenance, evaluating the extent of grout damage across a surface is critical before any tool is touched. Look for loose sections, hollow sounds when tapped, or crumbling edges around corners and heavily used areas like showers and backsplashes. The Grout Maintenance team found that a clear plan minimizes tile damage and speeds up the overall process. This section sets the foundation for a successful grout removal project that preserves tile integrity while delivering professional results.
Tools & Materials
- Grout removal tool (manual grout saw)(Crucial for initial scraping in narrow joints)
- Oscillating multi-tool with grout-removal blade(Faster on large areas; use with slow speed to avoid tile damage)
- Carbide grout removal blades(Attach to oscillating tool for efficiency)
- Utility knife or putty knife(Loosen grout in corners and edges)
- Safety gear (goggles, gloves, dust mask/respirator)(Protect eyes, hands, and lungs)
- Shop vacuum or dust extractor(Keep dust under control)
- Bucket and clean rags(Rinse frequently to avoid contamination)
- New grout (sanded/unsanded as appropriate)(Choose color and type; allow to cure)
- Grout sealer or topical sealant(Protect after regrouting (epoxy needs different handling))
- Masking tape and plastic sheeting(Protect surrounding surfaces from dust and drips)
Steps
Estimated time: 2-6 hours
- 1
Prepare the workspace
Clear the area, remove nearby items, and set up a temporary barrier to keep dust contained. Ventilate the area well and lay down drop cloths to protect floors. This helps you work cleanly and reduces cleanup after the job.
Tip: Open a window or use a fan with a filter to control dust. - 2
Protect surrounding surfaces
Apply masking tape to tile edges you want to preserve and cover countertops or glass with plastic. Dust will be generated, so a careful setup minimizes collateral damage.
Tip: Use plastic sheeting on vertical surfaces and tape tight to prevent dust intrusion. - 3
Choose your removal method
Decide between a manual grout saw for precise work or an oscillating tool for larger areas. Consider tile type and grout depth when choosing speed and blades.
Tip: If you’re unsure, start with the manual method to gauge tile integrity. - 4
Start at the edges and corners
Edges are the most prone to cracking during removal. Begin along corners and around fixtures, then work toward the center.
Tip: Keep blades perpendicular to joints to avoid gouging tile glaze. - 5
Grout removal in small sections
Scrape along the length of the joint with steady, even strokes. Work slowly to prevent chipping and to ensure you remove all loose grout.
Tip: Wipe the blade frequently to prevent grout buildup that can dull the edge. - 6
Clean debris frequently
Vacuum or sweep up loosened grout as you progress. Dust and debris hidden in joints can hinder resealing later.
Tip: Pause to vacuum every few joints for visibility and control. - 7
Check tile integrity
Inspect tiles for cracks or chips after removing grout in a section. If you see damage, adjust your approach and avoid further risk.
Tip: If damage is present, stop and assess whether the tile can be saved or needs repair. - 8
Dry the joints
Wipe away moisture and allow joints to dry completely before applying new grout. Moisture can affect grout adhesion and curing.
Tip: A small fan can help speed up drying time. - 9
Prepare for resealing or regrouting
Brush or wipe away any remaining dust, then plan your next steps for grout selection and application. This ensures even coverage and consistent color.
Tip: Decide on unsanded vs sanded grout based on tile gaps and tile type. - 10
Review safety and cleanup
Return tools, dispose of debris according to local guidelines, and seal the area to prevent future moisture intrusion.
Tip: Wear a mask during cleanup if dust levels are high.
Got Questions?
What tools do I need to remove grout from tiles?
You’ll typically need a grout removal tool (manual or powered), a utility knife, safety gear, a shop vacuum, and fresh grout for resealing. The exact choice depends on tile type and grout depth.
You’ll typically need a grout removal tool plus basic safety gear and a vacuum for cleanup.
Is grout removal safe for ceramic and porcelain tiles?
Yes, but you must use gentle tools and avoid applying heavy pressure near tile edges. Light scoring along the grout line minimizes chipping while still removing the grout.
Yes, but be gentle and stay along the grout line to protect tiles.
How long does grout removal take?
Removal time varies with area size and grout thickness. For a typical 50-100 square foot area, allocate several hours, including cleanup and regrouting prep.
It varies, but plan for several hours for a typical bath or kitchen area.
Can I reuse old grout after removing it?
No. Once grout is removed, you should use fresh grout because old grout may have degraded adhesion or color consistency and won’t seal properly.
No, use fresh grout for proper adhesion and appearance.
Will grout removal damage the tile itself?
If done carefully with the right tools, tile damage is minimal. The biggest risk is chipping at edges or near joints where grout is dense.
It can damage tiles if you’re too aggressive; use proper tools and light pressure.
Should I seal around the tiles after removing grout?
Yes, after regrouting and curing, seal the joints or use a grout sealer to enhance durability and stain resistance.
Seal after the new grout has cured to protect the joints.
The Essentials
- Plan before you cut to protect tiles.
- Use the right tool for the job to prevent damage.
- Clean as you go to improve resealing results.
- Dry joints thoroughly before grouting to ensure proper adhesion.
