ASBESTOS ROOF COATINGS questions

What is an asbestos roof coating?

An asbestos roof coating is a coating that can be applied to an asbestos roof to give a long-lasting, waterproofing solution.

Asbestos roofs have a lifespan of between 25 – 40 years; after this time they will start to degrade and can start to develop problems such as leaks, fibre shed etc.

Applying an asbestos roof coating can provide a fresh, clean look to the roof and will give a watertight solution. Another benefit of an asbestos roof coating is that it will help stop asbestos fibre shed and comes with warranties of up to 25 years.

Can you paint an asbestos roof?

An asbestos roof certainly can be painted. The reason for painting would be to give a fresh, new look to the roof, make the roof watertight and prevent asbestos fibre shed.

It is however vitally important that prior to painting, the asbestos roof is correctly prepared, and that any painting work undertaken is done so in line with HSE guidelines, with a proper asbestos roof paint and by a company who are approved installers by the paint manufacturer.

cladding coatings questions

Can you paint cladding?

Yes! By painting your cladding with the right paint, you can extend the lifetime of your cladding by up to fifteen years. It’s more cost effective than replacing cladding, and causes less disruption to your business. We offer a range of cladding spraying and painting services, and can tailor our solutions to your needs.

What are protective coatings?

Protective coatings are a simple way to reduce corrosion, by limiting the exposure of the metal to a corrosive environment. It can also be used to increase a materials aesthetic appeal.

What does HVLP stand for?

HVLP stands for ‘High-volume, low-pressure’.

What are HVLP sprayers?

HVLP Spray systems use a lightweight air turbine instead of a large air compressor to supply the air to atomise the paint. Being lightweight, means they are extremely portable. With HVLP Spray Guns, the air is supplied at a much lower pressure which means the amount of overspray is reduced as it is propelled at a much lower speed than conventional airspray. This can reduce time as well as cost – great for you, and our spraying contractors!

What does airless spray painting mean?

An airless sprayer pumps the paint under very high pressure via a specialised hose into a small hole in the nozzle of the sprayer. Airless spraying gives a smooth and even finish, which can withstand wear and tear as well as harmful corrosion effects.

Can you spray paint in cold weather?

Cold weather can make it difficult to spray paint. Paint will not stick to frosty surfaces, and even if it does, it may not cure properly. Other problems faced with painting in cold weather, include:

 

  • Paint becomes thicker and more difficult to apply (in extreme cold, it can even freeze!)
  • Spray gun may get clogged easily
  • Runs and drips are common
  • Colour uniformity can be poor
  • Damp can seep into uncured paint – this can cause stains and rust
  • We can advise you if the paint we are using for your project is suitable for particular temperatures.

Corrosion questions

What is cut edge corrosion?

Cladding sheets are coated when they are manufactured to protect them from the elements. When these sheets are cut to size, the edges aren’t re-coated, leaving them exposed. Over time, the edges of the cladding sheets are likely to rust. This can lead to leaks and eventually lead to the cladding panels needing to be replaced.

What is cut edge protection?

By treating the cut edge corrosion, you can prolong the lifespan of the panels. Cut edge protection includes:

  • Surface preparation and high pressure wash down
  • Removal of any loose paint and corrosion by hand grinding
  • Application of gun-applied sealant to fill any gaps
  • Re-spray cladding
  • Cladspray Solutions can offer guarantees against peeling, blistering and cracking for up to 20 years.
What is corrosion control?

Corrosion control is effectively removing any kind of corrosion or rust from a metal surface to prepare a clean, non-rusted metal before applying a protective coating to prevent the corrosion returning.

This is very important because corrosion is effectively the very first sign of a metal surface starting to break down and weaken. Once corrosion starts it spreads throughout the rest of the metal structure meaning that the structure loses its strength. Unless this corrosion is treated or ‘controlled’ at an early stage the metal can become too corroded which can then lead to costly metal replacement.

What are corrosion control methods?

Corrosion control methods are processes that are used to remove corrosion and rust and stop them spreading.

The only real method to control corrosion is to remove the corrosion and apply some kind of a protective coating to the treated area. It is imperative that the protective coating applied contains ‘anti-corrosive’ properties, to stop the corrosion returning.

What is corrosion control treatment?

Corrosion control treatment is the removal of corrosion and rust to prevent their spread throughout a metal structure.

The only truly effective method of corrosion control is to completely remove the corrosion and apply a protective coating to the treated area. It is imperative that all of the corrosion is completely removed and the protective coating applied contains ‘anti-corrosive’ properties, to stop the corrosion returning.

Why is corrosion control important?

Corrosion control is important because corrosion is effectively the very first sign of a metal surface starting to break down and weaken. Once corrosion starts, it spreads throughout the rest of the metal structure meaning that the structure loses its strength. Unless this corrosion is treated or ‘controlled’ at an early stage the metal can become too corroded which can then lead to costly metal replacement.

How to control corrosion of metals

Controlling corrosion of metals is done by firstly removing any kind of corrosion or rust from a metal surface to create a clean, non-rusted substrate before applying a protective coating to prevent the corrosion from returning.

floor coatings questions

What is epoxy floor coating?

Epoxy coatings are usually packaged in two parts that are mixed prior to application. The two parts consist of an epoxy resin, a co-reactant or hardener

When mixed together, they react to form a strong and durable plastic material. It’s so strong, it can be used in heavy traffic areas and industrial environments.

Why use epoxy floor coatings?

Whether you want to renew an existing floor coating, renovate a warehouse floor, mark out safe areas, or line a plant room or tank bund – commercial epoxy floor coatings provide you with a hard wearing, durable surface, available in a range of colours. Suitable for:

 

  • Car parks
  • Factories
  • Garages
  • Warehouses
  • Bunds

GUTTER LINING questions

What is a gutter lining?

A gutter lining is a thermoplastic system specifically engineered to restore and preserve gutter performance. Every gutter lining is made bespoke to fit perfectly into any size and shape of gutter. It provides a seamless “gutter within a gutter”, which is professionally fitted into an existing failing metal, plastic or asbestos gutter. It creates a new, watertight gutter which is designed to collect and disperse rainfall water from a roof via downpipes and outlets.

intumescent coatings questions

What is intumescent coating?

Intumescent coating, often referred to as intumescent paint, is used in buildings as a passive fire protection measure. When applied to structural steel, intumescent coatings form a protective layer on the surface. This will increase the time that the steel remains structurally sound during a fire to enable the building to be evacuated. To find out more about intumescent coatings, read our blog

PAINT SPRAYING questions

What can paint spraying be used for?

Paint spraying can be used for many applications. Paint spraying provides a more uniform application than the traditional brush and roller, which means the finish is superior. Paint spraying can be used for internal walls and ceilings, external masonry, cladding, roofs, windows, metal work and much more. Paint spraying can also be used for getting a painting project done much faster, therefore meaning less downtime for the business or person that the work is being done for.

Is paint spraying better than rolling?

Paint spraying is better than rolling because it is much faster and also gives a more uniform and even finish. By paint spraying you can achieve a ‘factory finish’, which is not possible with a roller.

What is industrial spray painting?

Industrial spray painting describes the method of painting industrial buildings and machinery using spray application rather than the more traditional brush and roller application.

Industrial spray painting is a much more efficient and effective means of applying paint to industrial buildings and machinery so the paint products can be applied quickly, with a better finish and at the correct paint thickness.

What is the industrial painting process?

The industrial painting process starts with assessing an industrial painting project and coming up with the most effective painting solution possible in order to achieve the best look and long term protection to the structure.

After initial assessments, a survey of the project is carried out with a bespoke painting specification written and the painting process undertaken in exact accordance with the paint manufacturer’s guidelines.

This industrial painting process ensures longevity for any industrial structure, whether this be a set of railings, a piece of machinery, or an entire building.

ROOF coatingS questions

What is a roof coating?

A roof coating is a roof repair and maintenance product that is applied to an industrial roof to prolong its lifespan.

Industrial roofs become damaged over time; whether the roof is made from metal, metal roof sheets, asbestos or fibre cement board, all are susceptible to weathering, which can cause a number of problems including cracked sheets, build-up of mould and vegetation, roof leaks, and corrosion.

If not tackled early enough, a roof can become damaged beyond repair, which could lead to the entire roof needing to be stripped off and replaced with a new roof – this can be very inconvenient and very costly.

Preparing a damaged roof and applying a new roof coating is a cost effective and convenient way of repairing problems with the roof and ensuring that the life span of the roof is increased dramatically. Roof coatings can be applied to old, failing roofs without having to stop the use of the building. The roof can be prepared and coated whilst the building remains fully operational meaning no down time for the residents or business within the building.

Roof coatings have warranties of up to 25 years so long term peace of mind can be achieved with a cost-effective solution.

Does a roof coating stop leaks?

Application of a roof coating will seal up and stop all existing roof leaks. A roof coating effectively creates a seamless waterproof membrane across the entire roof, which will seal up and holes, cracks, poor fixings etc to ensure a completely watertight system.

What are the benefits of roof coating vs replacement?

The benefits of a roof coating rather than a roof replacement are firstly that applying a roof coating will allow the building to remain fully operational throughout the process. With a roof replacement, this would mean that the existing, failing roof would need to be completely removed, resulting in an extended period where the building would be open to the elements, and would likely need to be temporarily closed down, resulting in loss of productivity and a large amount of disruption.

Secondly, a roof coating is also a far more cost-effective option, with typical figures being around a third of the cost of a roof replacement.

What is the roof coating process?

The process for a roof coating starts with a survey of the roof and a bespoke roof coating manufacturer’s specification written to carry out the work.

Any necessary scaffolding access would be installed and then the roof would be thoroughly cleaned to remove all contamination and any loose / flaking coatings.

In the case of a metal roof, all corrosion would be prepared back to a minimum of ST3 standard and spot primed. This would include all cut edge and sheet end corrosion, with any roof sheet laps being taped or silicone applied to ensure that there are no gaps between the sheet laps and to ensure that they are completely water tight.

For an asbestos roof, any damaged sheets would be repaired and any sheets with large cracks would be over sheeted with the same profile GRP sheet and spot primed.

Once all preparation is complete, the roof coating would then be applied, usually by airless spray application to ensure the correct roof coating thickness and a uniform finish is achieved. Multiple coats may be required depending on the product and warranty requirements.

The project would then be checked upon completion by the roof coating manufacturer, with a warranty subsequently being issued.

Do you do roof coatings for flat roofs?

Cladspray Solutions have several coating options for flat roofs. Just like any other roof, we are able to prepare and apply a roof coating to any type of flat roof to ensure a new, watertight coating solution is achieved. We can offer flat roof coating systems with warranties of up to 30 years.

SURFACE BLASTING questions

What is grit blasting?

Grit blasting, or abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.

Grit blasting is particularly useful for the removal of rust and old failing paint coatings to bring an old tired surface back to a bare, sound substrate. Grit blasting is also hugely effective in preparing corroded metal and poor masonry surfaces.

How does grit blasting work?

Abrasive blasting works by forcibly propelling a stream of material against a surface with a grit blasting rig and large compressor. The blasting rig is filled with abrasive blasting media and the compressor is used to create enough pressure to fire the grit at very high velocity, on to the surface.

This process will remove rust, contamination, salts, old failing coatings and damaged concrete to leave a clean, even surface ready for a coating system to be applied.

Why is grit blasting done?

Grit blasting is done to effectively remove rust, corrosion, mill scale, contaminants and old failing paint coatings to bring old, tired and failing surfaces back to a bare, sound substrate. Grit blasting is the most effective and fastest way to effectively prepare a surface prior to applying a coating system.

Is grit blasting hot work?

Grit blasting is classed as hot work because it can create sparks on the surface being blasted and also heats the surface as the friction from the abrasion of the grit hits the substrate.

What is steel grit blasting?

Like grit blasting, steel grit blasting is the operation of forcibly propelling a stream of abrasive material against a metal surface under high pressure to smooth a rough surface, but more specifically is usually used on newly fabricated structural steel to slightly roughen the surface in order for an anti-corrosive primer to be applied to prevent the steel from rusting.

Steel grit blasting is also used on rusted or corroded steel to remove the rust and corrosion to create a new, bright steel surface with no rust or contaminants, prior to re-painting with an anti-corrosive coating system. Steel grit blasting is the best possible preparation available for preparing corroded metal surfaces.

What is shot blasting?

Shot blasting is a surface treatment process using high velocity steel abrasive balls to remove existing paint coatings or to roughen up a smooth surface prior to painting. 

A large machine is usually moved across a surface at an even pace, firing small metal ball bearings at the surface at a very high velocity. These ball bearings break up the surface and can be used to open up very hard, dense concrete or remove existing old or failing floor coatings. 

Shot blasting is a method through which it is possible to obtain excellent cleaning and surface preparation for secondary finishing operations.

WINDOW SPRAYING QUESTIONS

Can you spray paint window frames?

Yes, window frames of any material type can be spray painted. There are many different type of window frames such as wooden, UPVC, metal, aluminium etc – the important point to consider is choosing the correct type of paint for the material that the window frame is made of. Cladspray Solutions have excellent knowledge about what type of paint or primer would be needed to spray paint any type of window frame.

Can you spray paint UPVC windows?

UPVC windows certainly can be spray painted. UPVC needs the correct primer coating to be applied to ensure that the paint adheres correctly to the UPVC and lasts for a very long time without cracking or peeling.

Cladspray Solutions have extensive knowledge about what type of paint or primer would be needed to spray paint UPVC windows.
