Primers & Reinforcement

To ensure strength, optimal waterproof properties and life expectancy up to 25 years, the use of a roof primer or roof reinforcement fleeces might be required before applying your roof paint. Whether you are dealing with a new roof or the renovation of an older roof, the right products for your project are essential. We stock a wide range of primers and reinforcement fleeces to ensure you can be equipped with all you will need for your roofing projects.

Flashing and roof primers are designed to provide a base for bituminous topcoats and roof sealants to adhere to on dusty and porous surfaces, promoting higher waterproofing capabilities and are an integral part of any roof coating installation. Roof primers are also critical parts of successful repair and renovation work, including the addition of skylights, solar-panels, etc. on previously waterproofed roofs.

Reinforcement Fleeces

Reinforcement fleeces are ideal to add additional strength, flexibility and durability to your roof. Especially when you are dealing with cracks, splits, holes or joins in roofing, the addition of reinforcement fleeces will increase the life expectancy of your roof and coating system. We stock a wide range of fleeces, suitable to be used in conjunction with a variety of roof coating systems such as those from Tor and Rust-Oleum.

Primers

Primers are great to ensure the substrate is in optimal condition for the next layer of paint. If you are renovating an existing roof, a primer might be needed to stabilize loose particles, to prepare weathered substrates or to prevent the absorption of moisture on porous substrates. If you are coating a completely new roof for the first time, we also stock primers to give your roof the maximum durability and life expectancy, on surfaces and substrates including:

  • Concrete
  • Asbestos
  • Cement
  • Metal
  • Mild Steel
  • Asphalt
  • Roofing felt
  • Zinc
  • Slate
  • Terracotta tiles
  • Lightweight concrete screeds
  • Masonry
  • Clay tiles

Many of these primers can be applied on damp (but not wet) roof surfaces to improve:

  • Low temperature flexibility
  • Heat and solar reflective capabilities of topcoat applications
  • Waterproofing
  • Colour retention – where applicable
  • High strength bond between the surface and the topcoat application
  • Stain-blocking
  • Improving the elevated level of tack on vertical surfaces
  • Extending the lifespan of previously aged and weathered surfaces
  • UV resistance
  • Chemical and pollution resistance
  • Protection against moss, algae and fungal growth
  • Crack bridging to prevent internal leaks
  • Minimise dirt retention
  • Resistant to water immersion in autumn and winter months

As we stock primers and reinforcement fleeces for various brands and for various surfaces, please do get in touch when you have any enquiries about the best products for your roofing project.


Guarantees, Warranties and Life Expectancies for Large Roofing Projects

Our roof coating systems are designed to waterproof, protect and decorate almost all types of roofing materials. Roof coatings are often the most cost effective way to renovate a roof by allowing the user to extend the life expectancy without the need of a specialist contractor.

However, often larger roofing projects require some form of ‘guarantee’ for the client and/or building owner to provide peace of mind that the coating system applied to the roof will protect/waterproof the roof for an agreed period of time.

We offer systems that can be used year round to provide upto 5, 10, 15 and 25 years protection when applied by an approved contractor to flat, metal, pitched, felt, asbestos, corrugated roofs and more. Cold applied, seamless systems mean no need for heat or naked flames providing tough, elastomeric, waterproofing coatings that withstand thermal/structural movement.

We will visit your site and carry out a full inspection, write a tailored specification to meet your requirements and offer an approved contractor for the application. We will never offer a contractor that we have not trained and approved, all our contractors have successfully completed specific product training on the systems they apply and are monitored regularly to ensure the highest standard of quality is achieved.

By using one of our nationwide approved contractors for our products you enable yourself to take advantage of our guarantees, life expectancies and warranties. This means that if we say our system is going to last a certain amount of time, or perform in a certain way and it doesn’t, you’re covered.

If you’re a contractor and would like to become an approved installer of our systems please contact us on 0113 245 5450
