Can You Apply Self-Levelling Compound Over Quarry Tiles?
Absolutely! You can lay self-levelling compound (SLC) over quarry tiles without the need for removal. No more back-breaking chipping away or chiselling! Instead, prepare yourself for a straightforward process that will save you time and effort. Before proceeding, ensure you understand the key steps involved to achieve a smooth, durable finish.
Important Precautions
Since quarry tiles are typically non-porous, applying SLC directly without proper preparation is not advisable. You will need to use a suitable primer to promote adhesion. Quarry tiles contain clay, which, like pottery, tends to retain water rather than absorb it. This characteristic makes them resistant to bonding if not properly primed, leading to potential issues down the line.
Choosing the Right Self-Levelling Compound for Quarry Tiles
If you’re shopping for a self-levelling compound, I highly recommend Ardex NA. Its compatibility with non-porous surfaces makes it an ideal choice. If you’ve already selected a different SLC, don’t worry—you can still proceed by using an appropriate primer. To simplify your project, I suggest opting for Ardex NA because it can be applied directly without a primer, streamlining the entire process and reducing potential errors.
Check out the Product Data Sheet for Ardex NA to see its specifications. For estimating the amount of SLC needed, consult our self-levelling compound calculator. This product has maintained consistent quality over the past eight years, proving its reliability. Its formulation allows for direct application, eliminating the need for extra steps like priming, so you can focus on pouring and levelling.
Application Tips and Techniques
When applying SLC, use a spiked roller. This tool helps eliminate air bubbles and ensures even distribution, resulting in a perfectly leveled surface. Avoid using a trowel, as it can create ridges or uneven patches. The roller technique guarantees a smooth, uniform finish.
Recommended Self-Levelling Compound and Primer
- Self-Levelling Compound: Ardex Arditex NA Powder & Latex (24.5kg) – £59.90
- No Primer Needed: This product is designed for easy application without additional priming.
- Features: Easy to spread due to latex content, it naturally levels itself, and offers excellent adhesion and flexibility even on challenging surfaces.
In my experience, latex-enhanced self-levelling compounds are much easier to work with than water-mixed versions. The latex component aids flowability and maintains flexibility after setting, which is especially beneficial for ground or upper-floor applications where slight movement occurs.
Best Primer for Applying SLC Over Quarry Tiles
If you’ve already purchased your SLC, selecting a suitable primer is crucial. I recommend Febond Blue Grit as the top primer for creating a strong, lasting bond over quarry tiles. It is compatible with virtually any self-levelling compound, ensuring reliable adhesion. Blue Grit works in two ways: it chemically bonds to the tile surface and provides a mechanical key through its coarse aggregate content. Once dried, it leaves a sandpaper-like rough surface, perfect for the SLC to grip tightly.
Applying Blue Grit is quick and simple—just roll it on using a brush or roller straight from the tub. No complicated mixing ratios or extra preparation required.
- Benefits: Ensures excellent adhesion on non-porous surfaces like quarry tiles, ceramic, porcelain, terrazzo, and other similar materials.
- Price: Around £18.31 for 5 liters.
Step-by-Step Guide to Using Self-Levelling Compound Over Quarry Tiles
Preparation is key to a successful application. Follow these essential steps for the best results:
- Clean Thoroughly: Ensure the surface is free of dust, grease, or any contaminants that could compromise adhesion.
- Prime the Surface: Apply your chosen primer (preferably Febond Blue Grit) with a roller and allow it to dry completely. If you’re using Ardex NA, you can skip this step.
- Mix the SLC: Prepare the self-levelling compound according to the manufacturer’s instructions. A cordless drill with a whisk attachment works best for thorough mixing.
- Pour Systematically: Starting from the back corner of the room, pour the mix across the surface, working methodically bucket by bucket to avoid gaps or overlaps.
- Distribute Evenly: Use a spiked roller to remove air bubbles and ensure uniform coverage. For edges and corners, use a flat trowel to smooth out the surface.
- Allow to Set: Wait patiently for the SLC to cure completely before walking on or applying any further flooring layers.
