Metalseal, BBA Approved Metal Roof Coating
Steel profiled industrial roofs have a design life of up to 40 years.
However, if the original factory applied finish is damaged or degraded, the life expectancy is drastically reduced.
Over time, coatings suffer from UV exposure and mechanical damage.
Cut edge corrosion is a common issue, as is complete failure of the original factory finish.
Liquasil’s BBA Approved metal roof coating is designed to provide long-term protection to metal roofs.
More than just a roof paint, Metalseal is a robust and economical alternative to complete roof replacement and causes minimal disruption to the building.
Our metal roof coating is a purpose-made silicone product that can be applied by brush, roller or airless spray.
It’s 100% UV stable, so will not fade or degrade over time.
Some silicone based, metal roof coatings are simply silicone sealant that has been diluted with solvent.
Metalseal is formulated by Liquasil and is builty from the ground up to overcome the problems associated with metal roofs.
Our metal roof coating is made from the ground-up, using specially selected silicone oils and polymers to produce a coating that is purpose-made for metal roofs.
We think it’s the best metal roof coating available. It certainly has the best credentials.
BBA Approved under certificate number 18/5536 (sheet 1), Metalseal is the first specialist metal roof coating on the market to have this approval and it’s also recommended by Kingspan, so you can specify and use it with 100% confidence.
Since 2013, Metalseal has been specified and installed on more than a million square metres of industrial metal roofs throughout the UK.
Once installed, Metalseal provides a permanent protective finish to metal profiled roofs. It’s resistant to UV degradation across all colours, so won’t fade and crack like some roof coatings.
Older installations of Metalseal can be easily cleaned with low pressure jet wash. Moss and lichen are a thing of the past because the product resists fungal growth.
Metal Roof Coating Cost
Metalseal is cheaper than many competing systems and, because it’s a single coat application*, it often costs less to install too.
The Metalseal system includes our unique cut edge corrosion primer to ensure that cut edge corrosion does not affect the Metalseal installation for the duration of its life.
Metalseal is guaranteed for 25 years against manufacturing defects.
If you require an insurance backed guarantee, your appointed Liquasil Approved Installer should be able to provide this at extra cost.
If you are involved in specifying metal roof coatings as a building surveyor or architect, it’s time to consider a cost effective alternative to the expensive and bloated coating systems that have traditionally been used for protecting metal roofs.
Metalseal is designed by Chartered Building Surveyors to provide you with a decorative and protective finish to keep your clients’ buildings in tip-top condition.
Our metal roof coating offers an economical and effective way of roof refurbishment and adds value for building owners.
Ease of application is key to all Liquasil systems.
Metalseal can be installed by airless spray, roller or brush, usually in a single coat, so is suitable for use on smaller and the largest metal roofs.
In most cases, Metalseal is applied in a single coat.
Uniquely for a silicone coating system, Metalseal is available in any RAL colour, subject to a minimum roof size of just 300 sq metres at no extra cost.
Preparation will depend on the condition of the substrate to which Metalseal is being applied.
If the substrate is in sound condition with no de-lamination of the existing finish apparent, then all that is needed is a roof clean using a high powered jet wash.
If cut edge corrosion is present and the substrate is in poor condition, we recommend that the surface is taken back to bare metal and we recommend a number of economical methods for doing this.
Metalseal as a Cladding Coating
Our dedicated cladding paint is a low-cost option for vertical cladding applications, but in some circumstances, Metalseal can be used.
Metalseal on vertical cladding provides a highly effective and long-lasting finish and is a highly effective barrier against grafitti.
In fact, Metalseal is so advanced, that if the coated surface is attacked by grafitti, either paint or marker pen, it will simply wash off with water and a little household detergent, to leave a completely ghost-free finish.
Because nothing sticks to the Metalseal surface, posters, stickers etc., are a thing of the past – they just won’t stay on the surface.
Metalseal out-performs most anti-graffiti coatings because of its unique hardened silicone composition.
If you’re considering coating vertical cladding, Metalseal is a compelling choice, but we do also provide a specially formulated, standard cladding paint for this purpose, which is considerably cheaper!

Metalseal is typically a single-aplication metal roof coating, but there are occasions when additional primers need to be used, depending on the condition of the roof.
There are many reasons why a coating might not fully adhere, but the most common is surface contamination.
For example, a bare galvanised roof that has been cleaned can still contain an invisible layer of zinc that can sometimes prevent adhesion.
A belt and braces approach should be taken on bare galvanised roofs, with the surface treated with Liquasil Galvanised Surface Primer.
This will help ensure your completed project is successful and will greatly enhance the life expectancy of the installation.
Adherence testing is always required on all surfaces and even though these might prove to be successful, using the galv primer will provide complete peace of mind for not too much more cost.
When specifying Metalseal for use on bare galvanised substrates, where the original coating has debonded, please include an extra-over cost for this option, because if the contractor’s adhesion tests are inconclusive, the primer will be required.
Metalseal is a soft coating that can be damaged by impact, abrasion or harsh jet washing.
Coated surfaces can be cleaned using low pressure jet wash, holding the lance at least 12 inches from the surface of the coating. Turbo lances must NOT be used.
Alternatively, smaller roofs can be cleaned using washing-up liquid and water, agitating the surface with a sponge or soft bristle car washing brush and then rinsing with clean water.
It is not a requirement of Liquasil’s product warranty that the surface is cleaned regularly, but it is a requirement that the installation is examined annually for signs of damage, which if present, can be touched up with more product once the surface has been cleaned.
Liquasil can also provide a compatible anti-fungicidal wash to kill any fungal growth that might be present on the surface.
