What is lacquer in construction?
Lacquer is a chemical compound that dries by evaporation and usually goes through a curing process to form a hard and durable coating. It can be clear or cloudy in appearance.
The term “lacquer” includes different types of synthetic coatings, such as nitrocellulose lacquers, acrylic lacquers, and polyurethane lacquers. These high-quality lacquers have various resins and solvents that provide the compound with the different characteristics required for specific applications.
These chemical compounds are valued for their quick drying duration, strong adhesive power, and the ability to create a glossy and pleasing finish.
What are the types of lacquers used in construction?
Lacquer is commonly used in the construction industry to enhance the durability and appearance of concrete paver blocks, besides other smaller applications.
The main types of lacquers used in the construction industry are –
Acrylic Lacquer
Acrylic lacquer is made from acrylic polymers. It is known for its excellent clarity, UV resistance, and ability to endure harsh weather. It is mostly used on exterior surfaces, including paving blocks, and helps protect the paved surface against sun damage. It also maintains color integrity over time.
Polyurethane Lacquer
Polyurethane lacquer is known for its superior toughness and resistance to chemicals and abrasion. Hence, this lacquer is often used in high-traffic areas. It provides a strong protective layer on paving blocks and makes them more resistant to wear and tear.
Water-Based Lacquer
Water-based lacquer is an eco-friendly option that is also extremely popular for its low Volatile Organic Compounds (VOC) content. These types of lacquer are safer for both the workers during the application of the lacquer and the environment. They are also preferred because they provide an attractive and durable finish.
Nitrocellulose Lacquer
Nitrocellulose lacquer is less commonly used in exterior applications due to its lower resistance to weathering. However, this lacquer is still used in construction projects where quick drying times and ease of application are needed.
What are the applications of lacquer in construction projects?
As mentioned before, lacquer is used in various industries besides construction. However, in this blog we are focusing on the use of lacquer in the construction industry. Applying lacquer on paving blocks requires several steps to ensure a high-quality finish and to maximize its protective and aesthetic benefits.
Here is a simple step-by-step process of applying lacquer in construction projects –
1 – Preparation
First, the paving blocks must be thoroughly cleaned and dried before lacquer is applied. Cleaning the paver surface involves removing any dirt, oil, debris, or other contaminants that could affect the adhesion of the lacquer to the paver block’s surface. Often, a mild acid is used to etch the surface slightly which enhances the lacquer’s grip on the paver block.
2 – Priming
At times, a primer can be applied to the paving blocks to further improve lacquer adhesion and its durability. The primer creates a uniform surface and seals porous materials. This allows the lacquer to form an even and consistent coating.
3 – Application
The lacquer can be applied using various methods, such as brushing, spraying, or rolling. Spraying is usually preferred as it helps to create a smooth, uniform coat, especially on uneven surfaces like paving blocks.
Multiple coats are normally applied, and each layer is allowed to dry completely before adding the next layer. This creates a thick, protective layer that enhances the durability and appearance of the paver block.
4 – Curing
Curing can be necessary, depending on the type of lacquer used. This requires allowing the lacquer to harden fully. Lacquer can take anywhere from a few hours to several days to cure completely. Curing ensures that the coating of lacquer attains its maximum hardness and protective capability.
5 – Maintenance
After application the maintenance of the lacquered surface is also necessary to ensure long-term performance. This involves regularly cleaning the lacquered surfaces to remove dirt and debris. It also involves regular re-application of lacquer to repair any damaged or worn areas.
Advantages of Using Lacquer in the Construction Industry
The application of lacquer on paving blocks has numerous benefits. This makes lacquers an attractive choice for various construction projects. These advantages include –
Enhanced Durability
Lacquer provides a protective shield to the paving blocks against environmental elements such as UV radiation, rain, and fluctuations in temperature. This protection extends the life of the paving block and reduces the need for frequent replacements and repairs.
Aesthetic Appeal
Lacquer also enhances the natural colors and textures of paving blocks, which creates a more visually appealing surface. The glossy finish provided by lacquer adds a touch of sophistication and can be modified to achieve various aesthetic effects, such as high gloss or matte finishes.
Resistance to Stains and Chemicals
Paved surfaces coated with lacquer are more resistant to stains from oil, grease, and other chemicals that are commonly seen in urban environments. This makes maintenance easier and helps preserve the clean appearance of paving blocks.
Improved Safety
Often, some lacquers can be designed with non-slip additives to enhance the safety of walking surfaces. This is particularly helpful in areas prone to getting wet frequently. This reduces the risk of accidents and improves the overall safety of public spaces.
Ease of Maintenance
Lacquer-coated paving blocks are also easier to clean and maintain. The smooth surface prevents dirt and debris from embedding deeply and makes routine cleaning more efficient. Besides this, minor damage can be repaired on the spot by applying lacquer which prolongs the life of the paving blocks.
Eco-Friendly Options
The use of water-based lacquers provides an environmentally friendly alternative to traditional solvent-based products. These lacquers emit lower VOC levels which reduces their impact on air quality and human health.
Cost-Effective
Though the initial application of lacquer may incur significant expenses, the extended lifespan and reduced maintenance costs of lacquered paving blocks can help make long-term savings. The need for fewer repairs and replacements also lowers overall project costs.
Versatility
Lacquer can be applied to a wide variety of paving materials, such as concrete, stones, and bricks. This versatility makes lacquer suitable for different construction projects, all the way from small residential buildings to huge commercial plazas.
What are the benefits of using lacquer on paving blocks?
Below are some examples to show the benefits of applying lacquer on paving blocks –
Commercial Plazas
Public plazas and pedestrian areas are frequently subjected to heavy foot traffic as well as harsh weather conditions. Lacquer-coated paving blocks in such areas have significantly improved the durability and appearance of the floor surface.
Residential Driveways
Homeowners are always on the lookout for ways to enhance the curb appeal of their properties. By applying polyurethane lacquer to the driveways, you can achieve a glossy, high-end look and protect the surface from oil stains, tire marks and similar damage.
Commercial Complexes
Large commercial complexes, such as shopping malls and office parks, also benefit from the protective and aesthetic properties of lacquered paving blocks.
Conclusion
The use of lacquer on paving blocks is a significant milestone in the construction industry and offers a wide variety of benefits, such as enhanced durability and improved aesthetics.
By understanding the types of lacquers available and their application processes, you can make the right decision and contribute to the longevity and appeal of the construction project.
Whether for urban plazas, residential driveways, or commercial complexes, lacquer provides a valuable solution for protecting and beautifying paving blocks. This ultimately leads to more sustainable and aesthetically pleasing constructions.
