How to Repair and Maintain Slate Flooring? Your Ultimate Guide

Are your slate tile floors looking worn out, dirty, or just in need of a little TLC?
If so, you’re not alone. Slate tile is a stunning and durable option for flooring. But it does require a bit of maintenance to keep it looking its best. Whether you’re dealing with a few stains or a completely worn-out floor, cleaning & sealing your slate tile can make a huge difference.
In this guide, we’ll walk you through the best practices for repairing, refinishing & sealing slate flooring to maintain its elegance. Let’s begin.
Why Slate Tile Floors Need Special Care | Identifying Issues
Slate is a stunning natural stone. It is known for its unique texture and rich colour variations. But slate is porous, which means it can absorb spills, dirt, and grime, making it more difficult to clean. Like any flooring, it can become damaged over time. Cracks, chips, and loose tiles are common issues. Here’s how to handle them:
1. Cracks in Slate Flooring
Small cracks can be fixed with a specialised slate repair adhesive. For larger cracks, you may need to replace the tile. This process typically involves removing the damaged tile and replacing it with a new one. This ensures that the new tile matches the surrounding ones.
2. Chips and Scratches
Minor chips and scratches can be repaired using a filler specifically designed for slate. Once applied, the filler should be sanded down to create a smooth, even surface that blends with the rest of the floor.
3. Loose Tiles
If a slate tile has become loose, it can be re-secured with a strong adhesive. Make sure to clean the surface thoroughly before applying the adhesive. And press the tile back into place until it’s fully set.
Regular maintenance is key to preserve the beauty of slate floor, ensuring it lasts for decades. So, let’s discuss about the slate cleaning process:
Slate Floor Cleaning and Sealing: The First Step to Long-Lasting Floors
If you want to keep your slate flooring looking brand new, slate cleaning should be your first priority. Regular cleaning prevents dust, grime, and dirt from settling into the surface.
Start by sweeping or vacuuming your slate floor regularly. For deep cleaning, use a mild soap or stone-specific cleaner. Always rinse with clean water to avoid leaving any residue.
Once your floor is cleaned, it’s time for the next step, slate floor sealing.
Sealing slate tiles is a must. It forms a protective barrier against dirt, moisture, and stains. Over time, sealing can wear off, so don’t forget about resealing slate floors every 1 or 2 years, especially in high-traffic areas. So, when sealing slate floors, make sure the sealer is specifically designed for slate.
Whether your slate floors are looking dull or your daily cleaning routine just isn’t cutting it anymore, refinishing may be the perfect solution. Let’s get into it:
DIY Slate Floor Restoration: How to Refinish Slate Tile
Refinishing slate is a two-step process: stripping the old sealant and applying a new one. But here’s a detailed step-by-step guide. With a bit of patience and the right tools, you can restore your floor’s original shine without needing a professional.
Step #1: Gather Your Supplies
Before you start, make sure you have everything you need for the job. Here’s what you’ll require:
- Chemical floor polish stripper
- Floor buffer with a stripping pad (or a good scrub brush if you’re doing it manually)
- Buckets for mixing stripper and clean water
- Wet vac or mop to clean up excess product
- Rags or towels for drying
- Protective gear (gloves, goggles, face mask)
You’ll also need a weekend or two (depending on the size of the area) to dedicate to this task. It’s a labour-intensive job. So, don’t rush.
Step #2: Strip the Old Finish
To start the refinishing process, you’ll need to strip off the old polish or wax. If you’ve previously sealed the floor, this step will also remove any built-up layers of old sealant.
- Apply the stripper – Using a mop or cloth, apply the stripper generously over a small section of your floor at a time. Make sure you follow the product instructions. Don’t let it dry before you start scrubbing.
- Scrub the surface – Once the stripper has had time to set (typically 10–15 minutes), scrub the area with a floor buffer and a stripping pad or a manual scrub brush. This step is important to get rid of any old wax and grime that has accumulated.
- Rinse thoroughly – After scrubbing, rinse the area with clean, cool water to remove all the stripper residue. It’s important to do this right away to prevent any residue from being trapped on the floor.
- Repeat the process – Continue this process until you’ve stripped the entire floor. Be prepared for some elbow grease.
Step #3: Let It Dry
Once the entire area is stripped and rinsed, allow the floor to dry completely.
It’s recommended to wait 24 hours before moving on to the next step. If you try to seal it while it’s still damp, the moisture will get trapped under the sealant, which can lead to further damage down the line.
Step #4: Apply a New Sealant
Once your floor is dry, it’s time to protect it with a fresh layer of sealant. This is where the real magic happens There are 2 types of sealers to look for:
1. Penetrating Sealers
These penetrate deep into the stone to fill in the pores. Thus, making the slate more resistant to stains without altering its appearance. Penetrating sealers tend to last longer, up to 15 years. They don’t change the look of your floor.
2. Topical Sealers
These form a protective layer on the surface of the slate. They can enhance the shine or matte finish of the tile and usually need to be reapplied every few years. If you want your slate to look glossy, this is the right option.
Apply the sealer with a mop or sponge. Start at one corner of the room and work your way toward an exit. So, you don’t get stuck in a corner. Be sure to follow the instructions and allow the sealer to cure as recommended.
Step #5: Let the Floor Dry
After applying the sealer, give the floor enough time to dry (usually about 12 hours).
If the instructions recommend a second coat, apply it after the first coat has dried completely. Be sure to give the second coat the same drying time. Once everything is dry and set, your floor will be ready to enjoy.
Grinding and Honing Slate Floors
For floors that have extensive damage or scratches, grinding and honing can smooth out the surface and bring back its natural shine. Professional floor restoration services will be required for this step. Contact us for reliable floor grinding and honing services in Perth.

How to Repair and Maintain Slate Flooring: Dealing with Damage
Sometimes, despite all the care you take, your slate floor might need a little repair. Cracks or chips can occur over time. Especially in high-traffic areas. Or if heavy objects are dropped on the floor.
If you have minor cracks, you can usually repair them yourself with a simple slate adhesive. For larger repairs or if you’re unsure, it’s best to consult a flooring expert who can do slate cleaning and sealing alongside the necessary repairs to restore the floor’s integrity.
Quick Tips for Maintaining Your Slate Tile Floors
Now that your slate tile floor looks brand new, you’ll want to keep it that way. Here are some tips for maintaining your newly refinished floor:
- Clean regularly: Sweep or vacuum your slate floors frequently to remove dirt and debris. This will prevent scratches from forming.
- Wipe up spills immediately: Slate is porous, and liquids can easily stain if left for too long. Wipe up the spills right away with a damp cloth.
- Avoid abrasive cleaners: Harsh chemicals can damage the sealant and the tile itself. Stick to mild soap and water or a gentle steam cleaner.
- Reseal every 1–2 years: Depending on the sealer you use, it’s important to reseal your slate floors every year or two. Check the product instructions for specific recommendations.
Conclusion
Slate flooring is an elegant and durable choice that can last for many years if properly maintained. Regular slate cleaning, and occasional floor sealing are essential steps in preserving its beauty and extending its lifespan.
Hence, cleaning and refinishing slate tile floors is something most homeowners in Perth can handle on their own. But there are some situations where hiring a professional can be the best option. If you have a large area to cover or if the floor has significant damage, a professional may be able to help you achieve a more polished finish.
