Prevent roof leaks in heavy rain – here’s how!

May 30, 2023 by The Cohe Team

Winter is coming, and so is the rain!

Although the rainy weather in New Zealand can be a beautiful sight for homeowners, it can bring about some unwelcome challenges, especially when it comes to roof leaks in heavy rain.

A leaky roof, whether it’s corrugated iron, metal, or concrete, not only poses a threat to your property but can also lead to expensive repairs and damage to your belongings.

However, there’s good news. With the proper knowledge and waterproofing products, you can effectively prevent roof leaks in heavy rain.

Do you want to know how to prevent roof leaks in heavy downfalls this winter? Keep reading to discover the importance of waterproofing your roof, along with DIY waterproofing solutions that aim to make your life much easier.

Why waterproofing your roof matters

Roof leaks in heavy rain are a common problem faced by homeowners worldwide. The combination of torrential downpours, strong winds, and compromised roofing materials can create an ideal environment for water to penetrate your roof’s protective layers.

Over time, this can lead to moisture seeping into your home, causing damage to the structure, insulation, and personal belongings.

Therefore, preventing roof leaks in heavy rain starts with effective waterproofing. Waterproofing your roof acts as a protective barrier against rainwater, ensuring that it flows away harmlessly without seeping through cracks, gaps, or damaged areas.

Here are just some of the reasons why you should consider waterproofing your roof:

Protection against water damage

One of the primary reasons for waterproofing your roof is to safeguard your home against water damage. A leaking roof can lead to a host of problems, such as weakened structural components, rotting wood, moss and mould growth, and damage to insulation and electrical systems.

Over time, these issues can become more severe and result in costly repairs. By applying a reliable waterproofing solution, you create a barrier that prevents water from seeping into your home, preserving its structural integrity and minimising the risk of damage.

Extended roof lifespan

Roof replacement is a significant investment for homeowners. Waterproofing your roof helps prolong its lifespan, saving you from the expenses associated with a premature roof replacement. By preventing water from infiltrating your roof, waterproofing solutions act as a protective shield, shielding your roofing materials from deterioration caused by moisture exposure. With a well-maintained, waterproof roof, you can expect it to last longer and provide reliable protection against various types of weather elements.

Energy efficiency and cost savings

A properly waterproofed roof contributes to improved energy efficiency and cost savings. Water infiltration can compromise the insulation in your home, leading to heat loss during the colder months and heat gain during the warmer months. This puts an additional strain on your heating and cooling systems, leading to increased energy consumption and higher utility bills.

Waterproofing your roof helps maintain the integrity of insulation materials, ensuring they function optimally and contribute to a more energy-efficient home. By reducing energy waste, you can benefit from significant cost savings on your energy bills over time.

Investing in quality waterproofing solutions will increase longevity and save you from the hassle and expense of dealing with leaks and subsequent repairs.

What is the best waterproofing for roof leaks in heavy rain?

When addressing a leaking roof, finding the best waterproofing solution is crucial – especially if you’re doing a DIY job.

With numerous products available in the market, choosing one that offers superior performance, durability, and ease of application is essential. In this regard, Cohe’s Liquid Rubber Waterproof Sealant stands out as an excellent choice that you can be confident in.

Best product to fix cracks in a concrete driveway – MG-Krete

April 27, 2023 by The Cohe Team

Winter weather can be tough on roads, paths and driveways, especially when they’re made of concrete.

Freeze/thaw cycles, heavy loads and persistent rains can all cause cracks to form in the surface of a concrete driveway, and if left untreated, these cracks can become larger, leading to even further damage.

With winter weather just around the corner, now is the time to take action – before it’s too late!

Why winter is the worst for concrete

Concrete’s biggest enemy is water and for many reasons. Winter is when it rains the most, so more rain means more water, which means more problems.

Concrete isn’t 100% waterproof, so rainwater will always seep into your driveway, no matter how recently you poured it. In winter, that water tends to freeze, and when water freezes, it expands, pushing everything around it. This freeze/thaw cycle is the most common reason for cracks in a concrete driveway.

Other culprits include soil settling and abiding rainfall, both of which are really just the same problem; water under your driveway. If the soil starts moving because it’s saturated, then the concrete on top will crack with the strain, just like a miniature earthquake.

On top of mother nature’s attack on your property, heavy loads such as cars and trucks can also cause cracks to form. If you own a larger vehicle, like a flatbed or a van, then you can expect more pressure and, therefore, more damage.

Fortunately, there is a solution that can help you fix those cracks before it’s too late: MG-Krete.

The ultimate concrete repair solution

MG-Krete is a specially-formulated product that is designed to repair cracks in concrete surfaces. Whether your concrete driveway has small surface-level cracks or more extensive damage, MG-Krete can help you restore it to a like-new condition.

It lasts much longer than traditional cement-based patch material and cures rapidly, so you can drive over it within 45 minutes! It withstands heavy traffic, doesn’t shrink, requires no long-term maintenance, and creates a surface that is more resistant to moisture, salt, gas and oils.

How to use MG-Krete to fix cracks in a concrete driveway

Here’s how to repair cracks in your driveway before winter weather arrives.

Step one: Assess the damage

The first step in repairing cracks in your driveway is to assess the severity of the damage. If the cracks are small and only surface-level, MG-Krete can be used to fill them in and create a seamless repair. However, if the cracks are more extensive or if there are multiple cracks in close proximity, a more comprehensive repair may be necessary.

Step two: Clean the area

Before applying MG-Krete, it’s important to clean the area around the crack to ensure a strong bond with the surrounding concrete. Use a wire brush or pressure washer to remove any dirt, debris or loose concrete.

Step three: Mix and apply the product

Follow the instructions on the packaging to mix the MG-Krete solution. For small cracks, you may only need a small amount of the product, while larger repairs may require more. Using a trowel or putty knife, apply the mixed MG-Krete to the crack or hole in your driveway. Work the product into the crack and smooth the surface to create a seamless repair. Make sure to apply the product evenly and avoid overfilling – you don’t want a speed bump in your driveway!

Step five: Allow to Dry

Allow the MG-Krete solution to dry for at least 45 minutes before using the driveway. During this time, make sure the area is protected from water, snow, and other weather conditions.

Fix cracks in your concrete driveway with our help!

MG-Krete is ideal not just for concrete driveways but also for an unlimited range of other repairs, including:

Roadways
Potholes
Footpaths
Industrial Floors
Parking Decks
Trip Hazards
Access Ramps
Steps & Stairs

As an official distributor, we sell the original MG-Krete repair solution to New Zealand’s homeowners, DIYers and professional construction workers.

Winter is coming and with it lots of rain and cold weather. If you have a few small cracks now in your driveway, get them fixed before they become a real problem by the time spring rolls around. Prevention is better than cure!

How to ensure your roof is waterproof using Cohe waterproof products

March 30, 2023 by The Cohe Team

As the saying goes, home is where the heart is, and the best way to protect it as we approach the winter months is to ensure your roof is waterproof. If you’re concerned about any small cracks and leaks following recent weather events like Cyclone Gabrielle, it’s better to be safe than sorry. A small hole can turn into a major headache for you long-term if left untreated.

Luckily, Cohe has a proven method for guaranteeing your home is safe from any wild weather.

Using simple products like our Cohe Quick Clean and Liquid Rubber Waterproof Sealant, you can safeguard your biggest asset from leaks in five easy steps.

Use our waterproof products on your roof before the winter weather sets in. Check out our five simple steps below!

Inspect your roof before you start

It’s important you inspect the soundness of the existing substrate. Confirm the roof drainage is functional and satisfactory before you begin the process of waterproofing your roof. If you find there is a pre-existing coating present, it could help to do a test run to determine the compatibility by testing a small area with waterproof sealant. Ensure there is no moisture trapped in the substrate before coating. Once you are satisfied the surface is satisfactory and ready to go, it’s on to step two!

Ensure you have a clean, dry surface with Cohe Quick Clean

Our Cohe Quick Clean is a fast-acting mould, mildew, algae and lichen remover, which is ideal for eliminating tricky contaminants from the surface of your roof. Spray the product and leave for at least three hours before using a trusty hose to remove all contaminants. Then allow the surface to fully dry again, as it must be free of moisture before you continue. Finally, tape off any areas of the roof that you don’t want any sealant applied to. Apply Cohe Quick Clean first thing in the morning or last thing at night to minimise evaporation. And it goes without saying, but make sure there is no rain expected for at least 6-12 hours.

Bridge joints, seams, vents and skylights with Liquid Rubber Seam Tape

Next, you need to peel off the plastic backing of your Liquid Rubber Seam Tape – a handy product used to seal gaps, tears and joins in your roof. You will see it has exposed the adhesive surface underneath. Apply this adhesive side down to all joints and cracks, 90° angles and protrusions. Go smoothly as you apply to ensure no air bubbles form. Once you’ve done this across all necessary areas of the roof, you are ready to immediately continue.

Apply Liquid Rubber Waterproof Sealant using a brush or roller

Liquid Rubber Waterproof Sealant is the best-loved sealer for all craftsmen and DIYers, thanks to its incredible adhesion to all types of substrates. Using this product, and a brush or roller from our handy Liquid Rubber Application Kit, apply a base layer of our waterproof product – paying particular attention to all joints or cracks. Wait 12 hours to let the first coat smooth over, and apply a top coat of the product, ensuring all air bubbles are removed, and the fabric of the seam tape is smooth.

You will want a minimum final thickness across your roof of ‘one litre per one square meter’ (it rhymes). This should be achieved with two heavy coats, and a 20-litre pail will coat 40 square meters. Once this is complete, leave to cure for 4-6 hours before walking on the surface of the roof. The best temperatures are between 10-25°C, and when not in contact with direct intense sunlight.

Apply Liquid Rubber Smooth Coating or Cohe C200 High-End Roof Coating

You’ve then got a good 72 hours to wait after applying the waterproof sealant, so put your feet up and relax for a while. Once the holiday is over, use one of our trusty coating products – Liquid Rubber Smooth Coating or Cohe C200 High End Roof Coating – to seal the deal. Apply the coating product heavily and wait for another 12 hours before applying a final coat. We recommend applying each coat in an alternate direction to the previous coat to ensure an even thickness. A 10-litre bucket will coat roofs up to 30 square meters. Use a minimum final thickness of one litre per three square meters. This will ensure the tough elastomeric roof coating can achieve its highest standard. Our Cohe C200 coating also has state-of-the-art UV absorbers that assist in surface protection from the effects of harsh New Zealand sunlight.

As always, we recommend you set out a tarp nearby to safely keep your pails and tools on. Also, make sure you have a pail of soap and water, rags and mineral spirits on hand. It pays to be prepared if an accident occurs, which you can clean up immediately and soak up with the rags.

And that’s it!

What waterproofing is the best to use?

Our waterproofing products have been helping Kiwis all over New Zealand complete DIY jobs in their own backyards for years.

Our most popular waterproofing product is Liquid Rubber. Liquid Rubber is a multi-purpose, liquid coating that solidifies into a tough, waterproof membrane.

The elastic nature of the coating means it can simply be painted onto any surface that isn’t oil-based, with the seamlessness covering getting into those hard-to-reach places that traditional waterproofing solutions can’t.

It can be used for waterproofing, as an air barrier, and as protection against corrosion. Adhering to most surfaces, once applied, the liquid turns into a waterproof rubber lasting up to a decade.

Here are some of the highlights that Liquid Rubber Waterproof Sealant offer:

UV-resistant
Waterproof
Chemically resistant
Temperature resistant
Environmentally friendly
Sustainable
Prevention of rotting wood
Corrosion protection

We have three types of Liquid Rubber available.

Liquid Rubber Waterproof Sealant

Liquid Rubber Waterproof Sealant is the perfect product for all your DIY waterproofing jobs around the house, farm, or workplace. Suitable for things like roofs, retaining walls, and ponds, it sticks to almost anything, including concrete, wood, and metal.

The basic form of Liquid Rubber is a universal sealer and protector for all craftsmen and kiwi DIY’ers.

Liquid Rubber Smooth Coating

Liquid Rubber Smooth Coating is designed as a topcoat for our Liquid Rubber Waterproof Sealant or on buildings requiring high UV/solar reflectivity.

It is a tough, water-based coating resistant to yellowing and age-crazing. The state-of-the-art UV absorbers incorporated in the mixture assist in surface protection from the effects of sunlight. This reflects heat and sunlight and reduces thermal heat transmission.

While Smooth Coating is not suitable as a waterproofing solvent on its own, it does increase the longevity of our regular Liquid Rubber by providing extra protection.

Liquid Rubber Deck Coating

Liquid Rubber Deck Coating provides a pleasing look and cost-effective surface for areas like patios, decks, and walkways.

Again, unsuitable as a waterproofing solution, the Deck Coating is designed to be used in conjunction with the Waterproof Sealant, making areas like factory floors or swimming pools more attractive.

Liquid Rubber Deck Coating comes in a standard light grey and can also be tinted on request.

We have three packs, depending on the area you need to cover: 10, 20 or 30 square metres.

An easy effective DIY solution to waterproof your deck for winter

June 10, 2022 by The Cohe Team

There’s nothing like relaxing out on your deck in the hot summer months, but have you thought about getting it ready for the cold wet months?

Waterproofing your deck in preparation for the cold weather is an important step that will prolong your deck’s lifespan, sustain its finish, and save you time, effort, and money in the long run.

It will also give you a head start on enjoying your deck in the spring and summer!

What are the benefits of waterproofing your deck?

Your deck is a valuable asset to your property and one that is most likely highly used and enjoyed by family and friends. However, it is also most susceptible to deterioration, as it’s exposed to the various weather elements that Mother Nature throws at it.

By ensuring your deck is waterproof, you’ll be gaining these benefits:

Slip resistance
Protection against rotting
Eliminates excessive moisture
Extended deck lifespan
Save money on expensive damage
Less maintenance and upkeep
Maintains a clean appearance

How often should you waterproof your deck?

Depending on what type of deck you have, in general, decks require annual upkeep, especially if you live in an area that’s exposed to wet weather. This will ensure their structural integrity remains intact.

Sealing your deck will also prevent splintering, rotting and cracking. However, if it’s been well maintained and hasn’t been exposed to extreme weather conditions you may only need to seal your deck every 2-3 years.

By waterproofing your deck with a quality waterproof sealant, you will also be protecting your deck from harsh sun exposure, therefore allowing your deck to last longer while maintaining a pristine appearance.

If you find that your deck easily absorbs water, then it’s time to waterproof your deck to prevent it from rotting over winter.

How can I make my deck waterproof?

Our Liquid Rubber Deck Coating is the easiest and most effective way to protect your deck over winter.

Liquid Rubber Deck Coating is designed to provide a pleasing look and cost-effective surface for areas like patios, decks, and walkways.

Our product is designed to be used in conjunction with our Waterproof Sealant, making areas like factory floors or swimming pools more attractive.

The sealant sticks to practically anything, and makes it perfect for things like roofs, retaining walls, and even ponds. This product is perfect for any DIY waterproofing job around the house, especially on your deck.

Once it has been applied, then it’s time for the Liquid Rubber Deck Coating as a topcoat, transforming your deck into something that’s not only beautiful but protected from the elements.

Because it uses high-performance polymers, it is resistant to yellowing and age crazing, and with its incorporated state of the art UV absorbers, it offers protection from the effects of sunlight that isn’t found in other products.

Apply Liquid Rubber Waterproof Sealant and Liquid Rubber Deck Coating

Liquid Rubber Waterproof Sealant can be applied to most substrates including:

Metal
Aluminium
Wood
Some plastics
Fibreglass
EPDM, PVC, and bonds well to most coatings

Prepare your deck

Before waterproofing your deck, you will want to ensure a satisfactory surface for application and inspect the soundness of the existing substrate. Confirm the deck’s drainage is satisfactory and functioning properly.

If an existing coating is present, determine the compatibility by testing a small area with the waterproof
sealant. Ensure there is no moisture trapped in the substrate before coating.

Before applying the waterproof sealant treat any moss or mould with COHE Quick Clean.

Remove any contaminants such as silicone, oil, grease flaking paint, dirt, and dust. Clean the surface of your deck using a high-pressure hose or water blaster to remove all contaminants.

Allow the surface to fully dry and tape off areas you do not want any sealant applied to.

Application

The larger your deck is, the more you are going to need to coat it.

As a general guide:

Four litres will cover 8 – 10 square metres
Ten litres will cover 10 – 20 square metres,
Twenty litres will cover 25 – 40 square metres.

Apply the waterproof sealant using either a brush or roller to achieve an even 1mm thickness across the surface. Apply two coats if applying to the porous surface or requiring a greater thickness.

Once applied, leave to cure for 4-6 hours before the surface can be walked on. After 72 hours, you can apply deck coating.

Apply 2 coats of deck coating at around 1L/3sqm per coat, waiting for a minimum of 12 hours between coats.

For more information and tips to ensure you do it correctly, you can download our easy to use application guide.
