Bond It Bitumen Primer 1Litre – For Roofing & Flashing Tape

Bond It Bitumen Primer 1L – For Roofing & Flashing Tape Product Description

Let's face it, when you've got a leak, a damp patch, or a draught, you want to sort it out properly and for good.

So, whether it's a leaky shed roof, a dodgy bit of felt, or a window frame that needs sealing, doing the job right the first time saves a massive headache down the line.

That's where Bond It Bitumen Primer comes in, so much so that you should think of it as the essential first step – the professional's secret – to a long-lasting, watertight repair.

What is Bond It Bitumen Primer?

So, what is it? In simple terms, this is a top-quality, highly penetrative black bituminous solution.

Its job is to prime and seal surfaces before you apply other bituminous materials, especially things like flashing tape, roofing felt, or a liquid waterproof coating.

It’s the all-important undercoat that makes sure your topcoat actually sticks and does its job properly.

Heavy-duty Formula

This heavy-duty formula is designed to soak deep into porous surfaces and create a solid, stable, and dust-free base.

So much so that it gets the surface perfectly ready, creating a powerful bond between the old material and the new repair you're about to apply.

Some would say it’s the difference between a quick patch-up and a permanent, professional-grade seal.

Why Do I Actually Need a Primer?

You might be tempted to skip the priming stage to save a bit of time, but that's often a false economy.

However, applying a primer is genuinely one of the most important steps in any roofing or sealing job.

Here’s why it makes such a difference:

It Creates a Super-Strong Bond

Imagine trying to stick a plaster onto a dusty or greasy surface – it just won’t hold properly.

It’s the same with roofing materials, as surfaces like concrete, brickwork, and old, weathered felt are often dusty, crumbly, or porous.

Bond It Bitumen Primer soaks right into these surfaces, sealing them and binding all the loose particles together.

This in turn creates the perfect, slightly tacky, and stable foundation for flashing tapes and topcoats to grip onto, ensuring they don't peel away when the weather turns.

It Stops the Surface from Sucking the Life Out of Your Topcoat

Porous surfaces like concrete or cement can suck the moisture and solvents out of any material you apply on top of them.

This then causes the topcoat or adhesive to dry far too quickly, which can lead to it becoming brittle, cracking, or not curing correctly.

The primer effectively seals the surface, stopping this from happening and allowing your repair material to dry and cure exactly as the manufacturer intended, giving you maximum performance and durability.

It Guarantees a Longer-Lasting Repair

At the end of the day, using a primer means your repair will last years longer.

By ensuring that you get a powerful, permanent bond and correct curing, you are massively reducing the risk of the repair failing, peeling, or leaking in the future.

For the small amount of time it takes to apply, it's a vital bit of insurance for your hard work.

Where Can I Use It? A Truly Multi-Purpose Formula

This isn't just a one-trick pony, as the heavy-duty formula of Bond It Bitumen Primer makes it suitable for a huge range of surfaces, making it a brilliant, adaptable tin to have in the garage or van.

Concrete, Screeds, and Renders

Perfect for priming concrete roofs before felting, or for sealing garage floors and workshop floors to reduce dust, as it soaks into the porous cementitious surface, creating an ideal base for floor paints or other waterproof coatings.

Existing Bitumen and Asphalt Surfaces

Got an old felt roof that’s looking a bit tired and weathered? This primer is ideal for breathing new life into old bitumen felt and mastic asphalt.

As it helps to rejuvenate the surface and prepares it perfectly for a new layer of felt, a patch repair, or an application of a liquid roof sealer.

Metalwork

Ideal for use on weathered corrugated iron and steel, like you’d find on farm buildings or old sheds, as it provides you with a protective, anti-corrosive layer and creates a grippy surface for a topcoat to bond to, which can often be a challenge on smooth metal.

Priming for Flashing Tape

Creates the perfect dust-free and tacky surface for self-adhesive flashing tapes to get a proper grip.

You can also use it around window frames, chimney stacks, and gutters to ensure a permanent, watertight seal that won't lift or peel away over time.

Preparing Concrete Roofs

An essential first step for flat concrete roofs, as it soaks in and seals the porous surface, preventing it from sucking the life out of your topcoat and providing a solid, stable base for applying roofing felt or liquid waterproof membranes.

Sealing Concrete Floors

Ideal for use on concrete garage or workshop floors, as it acts as a sealant to reduce annoying concrete dust and provides a fantastic key for a topcoat of floor paint, ensuring it won't flake or peel easily.

Rejuvenating Old Felt Roofs

Perfect for preparing tired, weathered, and brittle felt roofs for repair, as it helps to bind the old surface together, ready for a patch repair or a complete new layer of felt or liquid membrane to be applied on top.

Protecting Corrugated Metal

Use it to prime weathered corrugated iron or steel roofs on sheds, garages, and farm buildings, as it provides a grippy base for a protective topcoat to stick to and adds a valuable layer of anti-corrosive protection.

Sealing Brickwork and Walls

Seals porous brick and blockwork against damp penetration, as it’s ideal for preparing a wall before applying a waterproof render or for priming the area above a window or door before fitting a flashing strip.

Priming Mastic Asphalt

An excellent solution for preparing older, weathered mastic asphalt surfaces on balconies, walkways, or roofs, as it ensures any new repair material will bond powerfully with the old surface for a seamless, long-lasting fix.

Damp Proofing Foundations

Can be used as the first coat in a two-part damp proofing system for external foundation walls and retaining walls below ground level, as it primes the masonry, ready for a thicker bitumen topcoat to be applied.

Protecting Steel Beams and Lintels

Provides a protective primer coat for bare steelwork such as beams, lintels, or frames, as it helps to protect against rust and creates a suitable surface for further paint or protective coatings.

Preparing Wooden Fence Posts

It is also a great first step for protecting the section of a wooden fence post that will be buried in the ground, as it helps to prime the timber before applying a thicker bitumen paint helps to create a more effective barrier against moisture and rot.

The Perfect Partner for Flashing Tape

One of the main jobs for this primer is preparing surfaces for self-adhesive flashing tape.

Flashing tapes are just brilliant for sealing joints around windows, chimneys, gutters, and conservatories, but their performance is 100% dependent on how well they stick.

Consequently, applying a coat of Bond It Bitumen Primer first is a game-changer.

On a dusty brick wall or a porous concrete lintel, the primer gets in and seals the surface, giving the tape a clean, solid, and slightly tacky area to bond with.

This then ensures you get that instant, powerful grab and a fully waterproof seal that won't lift or peel over time, keeping wind and rain locked out for good.

How to Use It, A Simple Step-by-Step Guide

You don't need to be a professional roofer to get a great result with this primer, as it really is a doddle to apply with a brush or a roller.

Step 1: Get Prepped

First things first, safety.

This is a bitumen product, so wear some old clothes and a pair of gloves.

Make sure the area you’re working in is well-ventilated and give the tin a really good stir before you start, as some of the contents may have settled at the bottom.

Step 2: Prepare Your Surface

This is the most important step! Your surface must be clean, dry, and free from any grease, oil, dust, and loose material.

Use a stiff brush to sweep away all the dirt, moss, and flaky bits. If you wash the surface down, make sure it is completely dry before you start priming.

Step 3: Application

Using a brush or a roller, apply a thin, even coat to the entire area.

Don’t slap it on too thick – you don't want it to form pools or puddles.

You then need to work it well into the surface, making sure you cover every nook and cranny.

For a product like this, it's often best to use a cheap, disposable brush as it’ll be difficult to clean afterwards.

Step 4: Let It Dry

Allow the primer to dry completely before you apply anything on top.

Depending on the weather and the type of surface, this will usually take between 2 to 4 hours on a mild, dry day.

You'll know it's ready when it's touch-dry and has a slight tack to it. Now your surface is perfectly primed and ready for the next stage of your job.
