Understanding Concrete Laitance:

What Business Owners Need to Know

If you’re a business owner considering installing epoxy or polyurethane cement on your workshop floor, it’s essential to understand the concept of concrete laitance. At Diamond Grind, we ensure your floor is perfectly prepared for a durable and long-lasting finish. Here’s what you need to know about concrete laitance and why its removal is crucial.

What is Concrete Laitance?

Concrete laitance is a weak, thin layer of fine particles that forms on the surface of freshly poured concrete. This layer is typically composed of cement, water, and fine aggregates that rise to the surface during the curing process. Laitance can be problematic because it is not structurally sound and can lead to issues with adhesion and durability of any coatings applied over it.

Why is Concrete Laitance a Problem?

Concrete laitance can cause several issues that affect the performance and appearance of your workshop floor. Here are the key problems associated with concrete laitance:

• Poor Adhesion: Laitance prevents coatings like epoxy or polyurethane cement from properly bonding to the concrete substrate. This can lead to peeling, flaking, and premature failure of the coating.
• Weak Surface: The presence of laitance results in a weak surface layer that can easily break down under mechanical stress. This reduces the overall durability and lifespan of the floor.
• Aesthetic Issues: Laitance can cause uneven surfaces, discolouration, and a generally unattractive appearance. This can be particularly problematic in areas where a clean and professional look is important.
• Moisture Retention: Laitance can trap moisture within the concrete, leading to issues such as blistering and delamination of the coating. This trapped moisture can also promote the growth of mould and mildew, creating an unhealthy environment.
• Surface Contaminants: Laitance often contains contaminants like dust, dirt, and other fine particles. These contaminants can interfere with the adhesion of coatings and compromise the quality of the finished floor.
• Inconsistent Coating Thickness: When laitance is present, it can lead to an inconsistent application of the coating. This can result in areas of the floor that are more susceptible to wear and damage.
• Increased Maintenance Costs: Floors with laitance issues often require more frequent maintenance and repairs. This can lead to increased costs and downtime for your business.
• Safety Hazards: A weak and uneven floor surface can pose safety hazards, such as slips, trips, and falls. Ensuring a strong and even surface is crucial for maintaining a safe working environment.

How Diamond Grind Removes Concrete Laitance

At Diamond Grind, we use specialised techniques to remove concrete laitance, ensuring a strong and durable surface for your new floor coating. Here’s how we do it:

1. Surface Preparation: We begin by thoroughly cleaning the concrete surface to remove any dirt, grease, or debris.
2. Mechanical Grinding: Using advanced grinding equipment, we mechanically remove the laitance layer. This process exposes the solid concrete beneath, providing a strong base for the coating.
3. Vacuuming: After grinding, we vacuum the surface to remove any dust and particles, ensuring a clean and smooth substrate.
4. Moisture Testing: We conduct moisture tests to ensure the concrete is dry enough for the coating application, preventing future adhesion issues.

Why Choose Diamond Grind?

• Expertise: Our team has extensive experience in preparing concrete surfaces and applying high-quality epoxy and polyurethane coatings.
• Quality Equipment: We use state-of-the-art grinding and vacuuming equipment to ensure the best results.
• Customer Satisfaction: We prioritise your satisfaction and work diligently to deliver a floor that meets your expectations.
