Planning a flooring renovation? If you’re dealing with old tiles—especially those laid on a thick cement bed or screed—you’re likely facing a demolition job that can be a real nightmare. Think dust everywhere, structural vibration, and a huge, uneven mess left behind. Sound familiar? In Australia, particularly with older homes and wet areas (like bathrooms and laundries), tiles were often set in a substantial mortar bed (also called screed). Ripping this up requires more than just a hammer and chisel. The key is controlled demolition to ensure a clean, damage-free slate for your new floor. Let’s unpack the expert techniques that separate a messy DIY job from a professional, precise outcome. Why Is Tile on Screed Removal So Tricky, Mate? When tiles are "direct-stuck" to a concrete slab, removal is challenging but manageable. When they're laid on a thick bed of cement screed, the whole layer must often come up. This screed is essentially a layer of sand and cement used to level the subfloor or create essential drainage falls (slopes), particularly in wet areas. It’s tough, heavy, and firmly bonded. The Hazards of Brute-Force Demo Excessive Dust: Tile and screed demolition generates massive amounts of harmful silica dust. Without proper containment, this fine powder coats everything. Subfloor Damage: Aggressive jackhammering can crack or damage the structural concrete slab beneath the screed, leading to costly repairs. Vibration & Noise: This impacts the rest of the building's structure and makes the job unbearable for neighbours and occupants. Uneven Finish: A poor removal job leaves a patchy, uneven surface that makes your tiler's or floor layer's job much harder (and more expensive!). The Pro's Blueprint for Controlled Demolition The goal of precise tile removal and screed removal is maximum efficiency with minimum collateral damage. This is where specialised equipment and a smart process come in handy. Want to know how the professionals manage this complex floor preparation? Step 1: The Right Gear and Technique Forget the old sledgehammer. Modern, controlled demolition relies on power and precision: Specialised Jackhammers: Professionals use lighter, mid-range electric jackhammers (often SDS Max) with wide, purpose-built scraper or tile-lifting chisel bits. These tools are powerful enough to break the bond but are far more controlled than a full-sized jackhammer, reducing vibration. The Angle of Attack: The key technique is to keep the chisel bit flat, working parallel to the subfloor. This undercuts the screed and tile layers simultaneously, lifting them away without gouging the underlying concrete. Working from the Edge: Always start from a loose edge or carefully create a starting point to reduce resistance and control the material as it lifts. Step 2: Superior Dust Control (A Non-Negotiable) Effective dust-free tile removal is a hallmark of quality Australian flooring preparation. Silica dust is a serious health hazard. Professional teams use a multi-pronged approach: Containment: Setting up plastic barriers and airlocks to isolate the work area. Air Scrubbers: High-efficiency particulate air (HEPA) air scrubbers continuously filter the air, removing airborne dust particles. Grinder Dust Extraction: When tackling the stubborn mortar residue left on the slab, a concrete grinder with a HEPA vacuum attachment is essential for a near dust-free finish. This process ensures that when the demo is finished, your home isn't covered in a layer of fine, toxic dust. Finishing Strong: Preparing the Subfloor Removing the tile and screed is only half the battle. The crucial final step is subfloor preparation. Once the bulk of the material is gone, the underlying slab will still have mortar residue and small high points. This needs to be perfectly smooth and flat for the new flooring. A quality job includes: Grinding: Using a professional floor grinder with diamond cup wheels to remove all residual adhesive, ensuring a clean, perfectly bonded surface for the new installation. Levelling: Applying a self-levelling compound where necessary to fill any minor gouges or low spots, delivering a billiard-table-flat surface. A smooth substrate is absolutely critical to prevent your brand-new floor—whether it's large-format tiles or premium vinyl planking—from cracking or lifting prematurely. Key Takeaways for Your Next Flooring Reno Dealing with old sand and cement bedding shouldn't be a drama. Remember these points for a successful project: Screed = Controlled Demolition: It requires more finesse and power than direct-stick tile removal. Dust Control is Health Control: Always insist on HEPA filtration and containment for silica dust management. It’s All About Prep: The final concrete grinding step ensures your new floor is laid on a perfect foundation. If you're gearing up to remove old tiles and their thick mortar bed in a bathroom, kitchen, or laundry, don't risk the structural integrity of your home or the quality of your finished floor.
