How to Install Self-leveling Concrete Floors Over Tiles

When deciding to update your existing tile floor, choosing a self-leveling concrete overlay for your home, office, or retail store flooring will provide a durable, attractive, and cost-effective flooring solution that enhances the look and functionality of your space.

A new decorative concrete floor is more affordable than you might think. That’s because today’s concrete overlays can be installed directly over tile in a small amount of time.

Concrete has a natural beauty that will enhance any space. Subtle variations in color and texture give the floor a timeless appeal. The finish can also be tailored to achieve different effects. A high-gloss finish can create a reflective surface that adds depth and dimension to a room, while a matte finish can lend a more understated and contemporary feel.

Additionally, self-leveling concrete floors are highly durable, able to withstand heavy foot traffic, and resist wear and tear over time. This makes concrete ideal for high-traffic areas in residential and commercial settings.

What is a Self-leveling Concrete Floor?

Interior concrete floors can be installed using a product called a concrete overlay. A self-leveling concrete overlay is a type of polymer-modified cementitious topping that is poured onto an existing concrete, tile, plywood, metal, or other surface to create a smooth, level finish. It is designed to level uneven or rough substrates, filling in minor imperfections and creating a flat, uniform surface.

Self-leveling concrete overlays are often used to renovate and rejuvenate existing flooring, creating a new surface that is smooth, durable, and aesthetically pleasing. They are used in both residential and commercial properties and are cost-effective as compared to traditional concrete.

How Can I Tell if My Tile Floor Can Accept a Concrete Overlay Floor?

To determine if a tile floor is suitable for a new concrete overlay floor installation, several factors need to be assessed.

Tile Material and Texture

Concrete overlays are generally compatible with certain types of tile including ceramic, porcelain, and natural stone. Glazed and polished tile, will require additional surface preparation to promote adhesion.

Smooth, non-porous tiles usually require surface profiling or etching to create a suitable substrate for the concrete overlay to adhere to. Textured or rough tiles provide better adhesion.

Tile and Grout Condition

Ensure that the tiles are firmly adhered to the substrate. Note any loose or cracked tiles. Significant cracks, chips, or other damage to the tiles, could affect the performance and appearance of the new concrete floor.

Also, if the tile grout is cracked, crumbling, or uneven, it should be repaired or replaced before applying self-leveling concrete. Smooth, undamaged grout joints help to ensure a smooth and even surface for the new concrete floor.


Self-leveling concrete can level minor uneven surfaces on its own. If there are major deviations in the levelness of the substrate, additional coats of self-leveling concrete overlay may be required.

Moisture Issues

Assess the moisture levels in the substrate. Excessive moisture can affect the adhesion and performance of the concrete overlay. Perform a moisture test, such as a calcium chloride test or a relative humidity test, to determine if moisture mitigation measures are needed.

Customizable Designs

Self-leveling concrete overlays can be customized in multiple ways to suit any design motif. They can be stained in a wide range of colors, from earthy tones to vibrant hues, or stamped with intricate patterns and textures to mimic the look of natural stone, tile, or wood.


Self-leveling concrete overlays are incredibly durable and resistant to wear and tear. They can withstand heavy foot traffic, making them ideal for both residential and commercial settings. With proper maintenance, a concrete overlay can last for many years, saving you money on replacement and repair costs.


Concrete overlays can be installed over existing concrete, tile, wood, or vinyl flooring, making them a versatile option for almost any space. This versatility allows you to update your flooring without the need for extensive demolition or renovation.


Installing a concrete overlay is often more cost-effective than replacing the entire floor. It can save you money on labor and materials, especially if the existing floor is in relatively good condition.

Quick Installation

Concrete overlays can be installed relatively quickly, minimizing downtime and disruption to your daily routine or business operations. Unlike traditional concrete pouring, which can take days to cure, overlays can be ready for use in as little as 24 hours.

Low Maintenance

Once installed, concrete overlays are easy to maintain. They can be cleaned with a simple mop and mild detergent, and they are resistant to stains and spills, making them an ideal choice for busy households or high-traffic areas.

Environmentally Friendly

Concrete overlays are a sustainable flooring option, as they can be installed over existing surfaces, reducing the need for new materials. Additionally, concrete is a natural material that does not emit harmful VOCs (volatile organic compounds) into the air.Top of Form

Surface Preparation

Thoroughly clean the tile surface to remove any dirt, grease, wax, or other contaminants. Use a suitable cleaner and rinse the surface thoroughly.

Repair any damaged or loose tiles. Ensure that the tile surface is level and free of cracks or major imperfections.

If necessary, grind the tiles’ surface to remove any glaze or shine.


Apply Perdure E02 primer to the prepared tile surface and broadcast with sand. The primer and sand improve adhesion between the tile and the concrete overlay.

Once the Perdure E02 has set apply Duraamen’s Paramol as a second primer coat. Paramol is a premium-grade vinyl acetate primer specifically designed for self-leveling concrete floor installations.

Mixing the Concrete Overlay

Param 35M self-leveling concrete is mixed according to Duraamen’s instructions. It’s important to mix it to the right consistency to ensure proper flow and self-leveling properties.


Pour Param 35M self-leveling concrete overlay so that it maintains a thickness of 8–10mm.

Move the material around the surface and to the edges of the space using a squeegee or trowel while allowing the self-leveling properties of the Param 35M to work its magic.

Allow Param 35M to cure fully before proceeding with sealing or further finishing. Curing times may vary depending on environmental conditions. (note: Many concrete artisans have developed creative techniques to add unique and colorful design characteristics while the overlay is still fluid.)

Sealing and Finishing

Once Param 35M is fully cured, optionally add decorative effects or finishes to the concrete surface, such as staining, scoring, or polishing, to achieve the desired aesthetic.

Apply Perdure A03 acrylic sealer. Once the Perdure A03 is set, apply Perdure U45 urethane matte sealer or Perdure U46, urethane gloss sealer to protect the surface and enhance its appearance. Choose the sealer that provides the desired level of sheen.
