Metalseal BBA Certificate

Metalseal metal roof coating by Liquasil Ltd

Complete Metal Roof Refurbishment System

Steel profiled industrial roofs have a design life of up to 40 years, but if the original factory applied finish is damaged or degraded, the life expectancy is drastically reduced.

Over time, roof coatings suffer from UV exposure and mechanical damage that can result in complete failure, leaving the steel substrate susceptible to corrosion.

Liquasil’s Metal roof treatment is designed to provide long-term protection for metal roofs.

More affordable than a new roof or overcladding, Metalseal can be installed with little disruption to occupied buildings.

This purpose-made silicone roof coating system can be applied by brush, roller or airless spray usually in a single coat, making it quick and economical to install.

It’s 100% UV stable, so will not fade or degrade over time.

Metalseal is the ultimate protective coating for metal roofs in the UK and is the only one designed by Chartered Building Surveyors.

Unique Formulation

Made from the ground-up, Metalseal uses specially selected silicone oils and polymers to produce a coating that is purpose-made for the refurbishment of metal roofs.

BBA Approved under certificate number 18/5536 (sheet 1), Metalseal was the first specialist metal roof refurbishment system on the market to have this approval.

It’s also recommended by Kingspan, so you can specify and use it with 100% confidence.

During the past 10 years, Metalseal has been specified and installed on more than a million square metres of industrial metal roofs throughout the UK.

Metalseal provides a permanent protective finish to metal profiled roofs. It is resistant to UV degradation across all colours and won’t fade and crack over time.

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.

Two Grades

Metalseal is available in two versions, to suit individual application methods.

Where brush and roller application is preferred, we recommend Metalaseal SF, our solvent free version of Metalseal that has more body, which helps reduce sagging of the product on crowns and webs of profiled steel.

Both versions can be applied by brush and roller, but a more consistent film thickness is achievable across the installation with Metalseal SF.

Metalseal SF cannot be sprayed.

For spray application, we recommend Metalseal 20, as it is formulated to suit airless spraying.

This version contains a small amount of solvent to ensure that the product atomises and can pass through the spray gun.

Cost of Coating A Metal Roof

Metalseal is cheaper to buy and to install, than many competing systems.

More than just a coating, the Metalseal system will refresh and protect your steel profiled roof in a single application.

When installed by a trained, approved installer, the Metalsaeal system is covered by a 25 year product guarantee.

Insurance backed guarantees may be available from your  appointed Liquasil Approved Installer at extra cost.

Metalseal adds value for building owners at the lowest possible cost.

Brush Roller or Airless Spray Application

Ease of application is key to all Liquasil systems and Metalseal 20 can be installed by airless spray, roller or brush, usually in a single coat, so is suitable for use on small or large metal roofs.

For brush and roller application, we recommend Metalseal SF (Sobvent Free).

Both versions are available in any RAL colour, subject to a minimum roof size of just 300 sq metres at no extra cost.

Colour match  guaranteed between batches.

Preparation of the roof will depend on the condition of the substrate to which the product is being applied and can be as simple as jet washing the surface.

If cut edge corrosion is present and the substrate is in poor condition, we recommend that the surface is taken back to bare metal (ST3 standard) and we recommend a number of economical methods for doing this and we are happy to provide guidance where necessary.

Completed Metal Roof Coating Projects

Here are some completed projects using Metalseal 20. Each one of these roof coating projects has been carried out by independent, Liquasil Approved Contractors.

Whilst we don’t publish lists of our approved installers, we are happy to provide details upon request, based on geographical location, size of project and other factors that might be relevant to your project.

ADDITIONAL PRIMERS & TREATMENTS

*Galvanised Surfaces

A bare galvanised roof that has been cleaned can still contain an invisible layer of zinc that can hinder adhesion of new coatings.

Galvanised surfaces should be treated with a mordant solution, that should be rinsed off once activated.

This will help ensure project is successful and will also enhance the life expectancy of the installation.

Alternatively, Liquasil has a galv primer available for use on larger areas.

PVDF / PVF2 Coated Surfaces

Identifiable by its hard and smooth finish, PVF coated steel is notoriously difficult to overcoat.

The reason is that PVF contains Flourine which is used in the manufacture of many non-slip or non-stick coatings.

Liquasil has two dedicated PVF primers for use on PVF coated surfaces that ensures successful and long-term adhesion.

One is a two-pack epoxy and the other is a sprayable single pack product.

Cleaning Metalseal

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.
