Polyurea Application Process in construction work
Polyurethane is an excellent building material used in the construction work. This material provides excellent performance, durability and flexibility. It is a very strong and flexible coating that can be applied on various substrates to enhance their characteristics. Though this material has been used in the construction work for many years, it has gained popularity only in recent years due to its great properties and efficiency. The construction work using Polyurea Application as a base coat offers many benefits over other methods of using this product. If you are looking to get into some construction work then read on for details about application process, cost, maintenance, types of polyurea coating available, advantages and disadvantages.
What is Polyurea Application Process?
Polyurea coating is a coating that is made from polyurethane. This is a common product found in construction work. It is a polymeric coating that is applied to various substrates like concrete and brick, asphalt, etc. It is a durable, waterproof coating that provides excellent protection and resistance for the substrate against corrosion, heat and wear. This polyurethane coating can be applied on almost any surface. However, the surface that is used depends on the substrates. For instance, polyurethane coating is not suitable for wood, plaster, concrete and masonry. It is used as a coating on these substrates to enhance their shine and protect them from damage. Polyurea coating is a liquid base coating. This means that the coating is a solution that is applied onto the substrate. The base coat is applied at a thickness of 16-24 mil. This solution polymerizes at a temperature of 70- 80 °C. Once it has polymerized it forms the coating on the substrate. Polyurea coating is not a powder coating and it is not applied on a substrate by spraying. Polyurea coating is a one-coat system that means it has to be applied once.
Cost of Polyurea Construction Coating
Cost of polyurea coating depends on the type of coating, the substrate and the coating thickness. In general, one coat of polyurea costs about $4000. If you want to get two or three coats, it costs $12000-$17000. It costs $3500-$5200 to get one coat of polyurea on steel and about $2000 for the same on concrete. For aluminum, it costs around $2500. The cost of polyurea coating is relatively high both by itself and as compared to construction coating. Polyurea costs a lot as compared to other coating types. Since it is not a powder coating, it has a high application cost. Polyurea coatings are also expensive to maintain. It requires frequent application, clean-up and inspection. Hence, in the long run, it costs a lot.
Maintenance of Polyurea Building Coating
Polyurea coating does not have any maintenance requirement. It can be used in any construction work environment. Hence, it can be used in an outdoor environment without any maintenance. Polyurea coating is a liquid coating. It is not a powder coating that is liable to dust and dirt. Hence, it does not require any maintenance. Polyurea coating is easy to clean and can be cleaned with water. It can be used in a dry environment. Polyurea coating provides an excellent protection. It is a durable coating and hence can be used in outdoor construction work. Polyurea coating is a waterproof coating that provides protection against corrosion, heat, wear and weather. Hence, it is an ideal type of coating for exterior construction work.
Types of Polyurethane Coating
– Acid based Polyurethane Coating – This is one of the most popular types of polyurethane coating. It is a liquid base coating that is applied to the substrate with a brush or roller. It is applied in a thickness of 12-18 mils. Acid-based polyurethane is a good product for exterior construction work. It provides a smooth finish and protects the surface of the building. Its resistance against weather is good and it is an ideal coating for outdoor use. It can also be used in an indoor environment provided it is protected from sunlight. – Oil based Polyurethane Coating – This is a product that is used in roofing work. It is a thick liquid coating that is applied to the roof with a brush. Oil-based polyurethane is an excellent water repellent coating. It provides excellent protection to roofs from water, wind and sun. It has a special formula that prevents water penetration. It comes in two types, hot-melt and cold-melt. Hot-melt is a liquid that is applied to the substrate with a brush. It has to be applied in a thickness of 5-12 mils depending on the substrate. – Powder coat Polyurethane Coating – This is a type of polyurethane coating that comes in the form of a powder. It is mixed with water and applied to the substrate by spraying. Powder coat polyurethane coating is an ideal coating for interior walls and ceilings. It provides excellent resistance against water and heat. It is an ideal coating for the interior walls and ceilings of buildings. – Gel Coat Polyurethane Coating – This is a type of polyurethane coating that is applied with a brush or roller. It provides a smooth finish. Gel Coat polyurethane coating is an excellent product for exterior work. It is a high quality coating that protects the surface from the elements such as water, heat, rain and wind. – Epoxy Coating Polyurethane Coating – This is a type of polyurethane coating that comes in the form of an epoxy. It is applied to the substrate with a brush or roller. Epoxy polyurethane coating provides excellent protection for the surface of the building.
Advantages of using Polyurea in Construction Work
– Good Durability – This polyurethane coating is a durable building product. It provides good protection against the elements such as wind, rain, heat and sunlight. It is a heavy-duty coating that is suitable for outdoor use. – Excellent Water Repellent – Polyurethane coating is an excellent water repellent coating. It is non-porous and has a smooth texture. Hence, it is an ideal type of coating for exterior work. It keeps the water away from the surface of the building and provides protection against water damage. – Easy to Apply – Polyurethane coating is applied with a brush or roller. Hence, it is a one-coat system that means it does not require any other coat or primer coat. It is a ready-to-use product that does not need any mixing or application. – Light Weight – Polyurethane coating is light in weight and easy to apply. Thus, it is an ideal type of coating for scaffolding and cranes. – Cost Effective – Polyurethane coating is a cost effective building product. It provides good protection against the elements and is ideal for exterior construction work. – Sustainable – Polyurethane is considered as a sustainable building material. It is easy to apply and does not require any special tools for its application. Thus, it is a cost effective product that is environment-friendly. – Versatility – Polyurethane coating is versatile in nature. It can be used in both indoor and outdoor construction work. It is an excellent building product with many advantages.
Disadvantages of using Polyurea in Construction Work
– Expensive – Polyurethane coating is an expensive building product. It is available in the market at a high price. Hence, it can be used in the construction work only if financial viability is taken into consideration. – Needs regular cleaning – Polyurethane coating is a porous building material. It needs regular cleaning and inspection. It is good for protecting the surface of the building but it is not fireproof. – Not suitable for interior use – Polyurethane coating is not suitable for interior work as it requires regular cleaning and inspection. It is a porous material that is not fire-proof. So, it is recommended for exterior work only. – Not suitable for wooden and plaster substrates – Polyurethane is not suitable for wooden or plaster substrates as it does not adhere to the surface of these substrates. It is a liquid base coating that provides good protection against corrosion, heat and wear. – Not suitable for large surface areas – Polyurethane coating is basically a one-coat system that means it is applied once. Hence, it is cost effective. But it is not suitable for large surface areas.
