Are Concrete Brick Slips Safe to Use in the Home?

Concrete brick slips have grown in popularity in recent years as a stylish, durable, and cost-effective way to bring the industrial or rustic charm of brickwork into modern homes. Whether used for a feature wall, fireplace surround, or even an exterior facade, concrete brick slips offer both visual appeal and functional benefits. But for homeowners concerned with indoor air quality and health, a common question arises: do concrete brick slips emit any harmful toxins, or are they safe to use indoors?

Let’s explore what concrete brick slips are made of, whether they pose any health risks, and how to ensure a safe installation in your home.

What Are Concrete Brick Slips Made From?

Concrete brick slips are manufactured from a blend of cement, sand, aggregates, and water, often with added pigments to replicate the colour and texture of real brick. This mixture is poured into moulds and left to cure, resulting in thin, lightweight bricks that are ideal for decorative use.

Unlike ceramic or porcelain tiles, which are fired in a kiln, concrete brick slips are air-cured or treated using low-energy methods, making them more environmentally friendly in many cases.

Do Concrete Brick Slips Emit Harmful Toxins?

The short answer is: no, properly manufactured concrete brick slips do not emit harmful toxins.

Here’s why:

1. Inert Material

Concrete is classified as an inert material, meaning it doesn’t release volatile organic compounds (VOCs) or off-gas harmful chemicals once cured. This makes it safe for use indoors, especially in areas like living rooms, bedrooms, and kitchens.

2. No Combustible Chemicals

Concrete brick slips do not contain flammable or toxic chemicals. They’re non-combustible, which adds to their safety profile, particularly around stoves, fireplaces, or heaters.

3. Low-Emission Manufacturing (When Sourced Responsibly)

Reputable manufacturers follow strict health and safety standards and avoid the use of additives or sealants that could compromise air quality. Look for CE-marked or ISO-certified products, or those labeled VOC-free to ensure they meet health and safety regulations.

Things to Watch Out For

While concrete brick slips themselves are generally safe, some associated products could pose minor concerns if not chosen carefully:

• Adhesives and sealants: Some adhesives or surface sealers may contain VOCs. To keep your indoor air safe, choose low-VOC or VOC-free options whenever possible.

• Dust during installation: Cutting or sanding concrete brick slips can create dust. It’s important to wear a mask and ensure proper ventilation during installation. Once installed, they’re completely safe and maintenance-free.

Conclusion

Concrete brick slips are a safe, non-toxic choice for interior walls and decorative projects. They do not emit harmful gases or toxins once cured, making them ideal for use in the home. As long as they are sourced from reputable suppliers and installed with suitable adhesives and safety precautions, concrete brick slips offer a durable, stylish, and healthy solution for adding character to any space.
