POLYUREA COATINGS & LININGS
Polyurea is a remarkable technology with an almost unlimited range of uses. It is far more durable than paint and typically lasts much longer between maintenance cycles. Polyurea is the clear choice when it comes to cost/performance payback and operation.
As with all our coating systems, we use the correct application equipment and always ensure that surfaces are properly prepared and primed, where necessary.
Polyurea protective membranes do not contain any volatile organic compounds and solvents and can be applied to concrete, steel, aluminium, plastic, fibreglass, wood, foam and other surfaces, using mobile applicators and advanced application equipment. Within seconds of application, they will not only resist punctures but resist heat distortion and sagging, maintain their flexibility and shape and last for about 25 years, depending on the nature of the project, substantially cutting the cost of repairs and maintenance.
Furthermore, polyurea coatings:
- are not affected by moisture and fluctuations in temperature
- can be applied in high moisture and humid conditions
- have high elongation and superior tensile strength that allows for movement of the substrate
- are resistant to ultraviolet radiation, salt-water and aggressive atmospheric conditions
- can transgress multiple substrates in one application
- can be applied in any colour to any thickness in a single application
- are fast curing allowing quick turnaround and load bearing after one hour
- are spray applied, ensuring even and continuous coverage providing a seamless sealant
- have good adhesion properties that can be applied to a wide range of substrates
- have high hydrolysis and ageing resistance properties resulting in a long-lasting waterproof sealant
- have good abrasion and impact resistance properties to withstand harsh conditions
- feature good chemical resistance properties offering a specialised chemical sealant to withstand high acid and corrosive environments
The high number of leaking and water damaged roofs in South Africa are often caused by worn and damaged sealants, complicated roof penetrations, skylights and air-conditioning ducts to name a few. These inherently result in high consequential costs such as structural damage, equipment and interior property damage as well as contributing to the overall deterioration of the property.
Polyurea spray sealants offer the property owner a quick and reliable solution with its fast set nature. It can typically render an area serviceable many times faster than traditional sealants, allowing the owner to put the facility back in use without days of costly down-time. This unique sealant system adds years to the life of any surface and with its outstanding elongation properties eliminate cracking, peeling and splitting of the sealant. Furthermore, the Polyurea spray sealants provide an impermeable barrier against rust, corrosion, weather and chemical seepage.
Pipes / Pipelines
Polyurea coatings and linings are used to protect steel pipes from corrosion and have demonstrated their ability to last longer than paint, reducing both maintenance services and costs.
Polyurea is an excellent protective coating system for pipes that are insulated with polyurethane foam.
Polyurea is also used to line the inside of water and sewer pipes for infrastructure rehabilitation work.
Polyurea coatings protect steel tanks from corrosion, chemicals, and other natural weather elements and can be applied during primary construction or in a retrofit environment. Polyureas are great for extending the life of older tanks and offer limited structural characteristics as well. Their fast cure times are ideal for retrofits since down time is significantly minimized compared to other competing materials.
Polyurea linings are resistant to many chemicals and industrial liquids. With their fast application advantages and ability to adhere to properly prepared substrates, Polyureas are ideal for new storage tank primary lining and rehabilitation projects.
Roofs and Decks
Polyurea coatings make an excellent protective covering for polyurethane foam roofs. Some systems have reflective coatings that help reduce the amount energy consumption buildings use for heating and cooling.
Flooring and Parking Decks
Polyurea flooring systems are best known for their rapid turnaround installation capabilities and durability in high traffic areas. They are also used as waterproofing and protect against the daily pressure cleaning operations in clean/dirty rooms. Polyurea can be formulated to be flexible and resilient allowing the flooring system to protect objects that may fall upon them.
Polyurea is a very fast set material, which makes it ideal for use in line striping and pavement marking as it can be returned to service for traffic and pedestrian use in only a few minutes after application.
Joint Fill / Caulk
Polyurea is successfully used as a multi-purpose joint fill, caulking and sealant material. It provides a flexible, durable, weather-tight and traffic resistant seal for all types of building joints, such as expansion joints and control joints in masonry floors, perimeter joints, panels and doors, water reservoirs, etc. It has excellent crack-bridging properties with high elongation and tensile strength.
Fuel Storage & Containment
Polyurea is resistant to many fuels and chemicals and is commonly used in fuel pits and pipeline secondary containment. The necessary compatibility tests for chemical resistance will be undertaken where required.
Waste Water Treatment Plants
With its fast curing time and superior chemical and abrasion resistance, Polyurea is the ideal application for concrete primary and secondary containment linings.
Manholes & Sewers
Polyurea manhole linings solve the issue of groundwater infiltration and installation speeds for those municipalities and private water systems that are in need of lining and structural repair. Polyurea’s ability to form a monolithic, durable liner protects the cavity from sediment and groundwater infiltration into municipal wastewater systems.
Polyurea effectively protects steel, aluminium, and fibreglass in a variety of water sport and commercial marine applications where resistance to abrasion, chemicals and corrosion are a prerequisite. From fish hold liners to hull protection and bilge liners, Polyureas are used in numerous marine applications.
Theme Parks & Decorative Design
Polyurea can be used as a protective coating over foam, EPS and other structures to create ornamental building fascias, themed characters, artificial rocks, pools and environments.
Water Parks & Playgrounds
Moulded slides, protective coating of seats for wet/dry amusement rides, tank linings, water containment, aquariums and concrete stadium seats are just a few of the many applications. Polyureas are commonly used for in the amusement and theme park industry. Polyurea’s usage is rapidly growing in applications to replace paint and fibreglass due its fast cure and ability to reduce maintenance cycles.
Polyurea’s excellent resistance to water and availability in a variety of colours, together with its ability to form to custom shapes, make this system desirable.
Landscape & Water Containment
Polyurea is used by landscape designers and contractors as a primary liner to contain water in ponds and pool decorations and can be used conjunction with geotextile material when applying over dirt.
Polyurea has much the same uses in architectural design as it does in theme park applications. Polyurea is used as a protective coating over foam, EPS and other structures to create ornamental building fascias, themed characters, artificial rocks, pools and environments. It can also be used in movie set and theatre stage designs.
Polyurea truck bed liners form abrasion resistant, durable, water and air-tight permanent liners for the exterior of pick- up trucks, dump trucks and steel containers. They also protect against rust and corrosion and can be applied in varied thicknesses and colours to meet the specific application demand.
Railcars & Track Containment
Polyureas are commonly used for their waterproofing and chemical resistance properties to line liquid containment railcars whilst hopper style railcars have benefited from the strength of Polyurea and its ability to resist surface damage from coal, sand, and other abrasive materials. Polyurea can be applied quickly and will last longer than many other conventional systems.
