Concrete structures are the backbone of modern construction, forming everything from bridges and tunnels to commercial and residential buildings. Ensuring their long-term performance requires proactive protection against environmental and mechanical stresses. With the right solutions, concrete can maintain its strength, appearance, and functionality for decades.
Concrete is one of the most durable building materials, but exposure to moisture, chemicals, and environmental stress can cause deterioration over time. Sika offers a wide range of concrete protective coatings designed to extend the lifespan of structures, improve durability, and reduce maintenance costs.
What Are Resinous Repair Mortars and Concretes?
Concrete protective coatings are specialized materials applied to concrete surfaces to shield them from damage caused by moisture, chemicals, UV exposure, and wear over time. These coatings act as a barrier, preventing water penetration, corrosion of reinforcement, and surface deterioration, while also enhancing the aesthetic appearance of the structure.
Depending on the type, coatings can provide:
Waterproofing: Stops water ingress and reduces freeze-thaw damage.
Chemical Resistance: Protects concrete from aggressive substances like acids, salts, and industrial chemicals.
Durability & Longevity: Extends the service life of structures and reduces maintenance costs.
Specialised Protection: Anti-graffiti, hydrophobic treatments, and UV-resistant finishes.
Applications of Concrete Protective Coatings
Primers
Sika UK offers a comprehensive range of concrete protection primers designed to ensure optimal adhesion and longevity of protective coatings on various concrete surfaces.
Whether you're working with dense, porous, or challenging substrates, our primers provide the essential foundation for superior coating performance. Each product is formulated to meet specific application needs, ensuring reliable results across diverse construction projects.
Waterbased Coatings
Concrete structures are constantly exposed to environmental stresses such as moisture, temperature fluctuations, and chemical attack, which can compromise their durability over time. Water-based coatings provide an effective, sustainable solution to safeguard these surfaces, offering excellent adhesion, flexibility, and resistance to water ingress.
They are ideal for a wide range of applications, from infrastructure projects to commercial and industrial buildings, ensuring long-lasting protection while being environmentally responsible. Sika UK offers a variety of high-performance water-based coatings designed to meet different project requirements.
Resin Based Coatings
Concrete structures are exposed to various environmental challenges, including chemical attacks, moisture ingress, and mechanical stresses. Resin-based coatings offer a robust solution to protect concrete surfaces, providing enhanced durability and resistance against harsh conditions. These coatings are ideal for applications in industries such as water treatment, chemical processing, and infrastructure, where long-term protection is essential.
Sika UK provides a comprehensive range of resin-based coatings designed to meet the diverse needs of concrete protection. Each product is engineered to ensure optimal performance, longevity, and compliance with industry standards.
Intermediate Coatings
Intermediate coatings play a crucial role in concrete protection systems by providing an additional layer that enhances adhesion, crack-bridging capabilities, and resistance to environmental stresses. These coatings are particularly beneficial in applications where substrates require surface levelling or where enhanced protection against carbonation and moisture ingress is needed. By serving as a bridge between primers and topcoats, intermediate coatings ensure the longevity and effectiveness of the entire protective system.
Cementitious Based Coatings
Cementitious-based coatings provide a robust, reliable solution for protecting concrete surfaces against moisture ingress, carbonation, and general wear.
Sika’s Sikagard®-5901 Eproseal is a high-performance, cementitious coating designed to deliver excellent adhesion and waterproofing for a variety of applications, including water storage tanks, basements, and structural concrete. Its durable formulation ensures long-lasting protection while seamlessly integrating into Sika’s comprehensive concrete protection systems.
Chemical Resistant Coatings
Concrete surfaces in industrial, chemical, and wastewater environments are constantly exposed to aggressive substances that can compromise durability and safety. Sika’s chemical resistant coatings provide a high-performance barrier against acids, alkalis, solvents, and other corrosive chemicals, ensuring long-term protection and structural integrity. These coatings are engineered to deliver excellent adhesion, resistance to chemical attack, and ease of application
Anti-Graffiti Coatings
Concrete surfaces in urban environments are often subjected to vandalism, including graffiti and unauthorised posters, leading to aesthetic degradation and increased maintenance costs. Anti-graffiti coatings provide an effective solution to protect these surfaces, allowing for easy removal of unwanted markings and posters without damaging the underlying material.
These coatings are designed to offer long-lasting protection, reducing the frequency and cost of cleaning and maintenance.
