The only DIY moss and mould killer needed to get the job done right

April 13, 2022 by The Cohe Team

Winter is approaching and before it sets in, now is the time to remove any moss or mould on your house before the cold weather brings dampness, which often promotes more moss, mould and fungus.

If you’ve found moss or mould in your home or building, there’s a high chance that there will be plenty more where that came from, and removal of the moss and mould is now a priority.

Moss and mould and other growths are not only harmful to your health, but they cause expensive damage to your home if left untreated.

We’ve come up with an affordable safe and easy way for you to remove moss and mould DIY style with our Cohe Moss and Mould Killer.

What is the difference between moss and mould?

Moss and mould may look similar, but they are in fact very different from each other. Moss is a plant that converts sunlight and dissolved soil minerals into the energy it needs to grow and reproduce. It has very few uses, but one of its uses is gardening.

Mould is a fungus that is made up of multiple cells and gets energy from the organic matter it lives on. Mould grows best in damp and poorly ventilated areas and reproduces by making airborne spores. Unlike moss, mould doesn’t need sunlight to live.

Why should you remove moss and mould from your home?

Why remove moss?

Moss is bad for any building material and can cause expensive damage. It draws moisture from that material, breaks down its colour first, and etches progressively more deeply into the product. Worse still, it can lead to rotting and provides cover for fungus, which is much more destructive as the fungus has the ability to decompose materials.

Why remove mould?

Although mould is a natural part of our ecosystem, when household mould growth gets out of hand it can not only affect your home but your family’s health.

Moulds are present virtually everywhere, indoors, and outdoors and can grow in and on materials such as food, furniture, fabrics, carpets, walls, paper, roofs, timber, and plumbing. Mould can cause leaks, stains and rot which can lead to costing you thousands of dollars in repair costs.

Mould can also make your home uninviting and worn down.

However, the number one reason why you should remove moss and mould is for your family’s health.

Moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances. Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes, and skin rash. Moulds can also cause asthma attacks and lung issues.

How to remove moss and mould the safe and easy way

Cohe Moss & Mould Kill is super simple to use. It’s long-lasting and extra effective at removing growths from a wide range of surfaces.

We know that the DIY way is popular with Kiwis across New Zealand, and we all to some extent, think of ourselves as ‘DIYers’. This product is the best no-fuss moss and mould killer that you can use at home.

Instructions for use

Ensure your surfaces are clean and free of loose debris. Use a broom or leaf blower to help clear any loose matter away.
Make sure the spray will not contaminate water sources (if you have water out for pets move it away to prevent overspray. Or, if you have a water tank connected to the roof or gutters, make sure you disconnect them for at least 14 days after spraying).
Use a low-pressure sprayer, and dilute Cohe Moss & Mould Kill with water at a 1:20 ratio (You can alter this ratio depending on how much growth there is on your surfaces).
Then, all you need to do is spray Cohe Moss & Mould killer onto the surface, and then walk away.
Done – it’s really that simple.

Our mould and moss killing solution works so well because it takes time to actively target the new growth of spores. Over just a few months you will see the product working and taking effect with complete results around the three-month mark.

Tips for moss and mould removal

For best results allow a dry contact time of at least 3 hours. Most surfaces do not require rinsing although some aged painted surfaces may require a rinse to avoid streaking
Best applied first thing in the morning or last thing at night onto a cool surface to minimise evaporation
For optimum results apply in sunny and dry conditions with no rain expected for at least 12 hours

Use the Moss and Mould Killer that works

Don’t let moss and mould shorten the life span of your roof, damage your paint and rot the exterior of your home by using Cohe Moss & Mould Kill as soon as the problem appears.

By eliminating moss and mould from your property, you’re creating a safer and healthier environment for your household while saving on potential repair expenses in the future.

The best concrete waterproofing sealer that’s quick and easy to use

December 14, 2021 by The Cohe Team

Are you looking for a concrete waterproofing sealer that’s quick and easy to use?

Concrete maintenance is often one of the last things to be looked at on a DIY to-do list, and with the different types of concrete available, it can be difficult to know how to maintain it.

If your home or business has concrete that needs to be kept in its ultimate condition that’s protected against water damage – then we’re here to tell you about the best concrete waterproofing sealer that will get your job done!

Why use a concrete waterproofing sealer?

Standard concrete may seem strong enough on its own without any waterproofing sealer or repair treatment. Concrete may already seem waterproof; however, that’s not entirely the case.

Concrete is naturally porous and prone to water absorption. The tiny pores of a concrete slab and foundation can absorb water if not treated with a waterproofing concrete sealer.

Using a concrete waterproofing sealer prevents cracks from forming, and the more cracks that appear, the more water can get in.

The wear and tear of concrete will slowly show over time, but if the surface of the concrete starts to deteriorate, then the inside structure may be as well.

This deterioration is what you want to avoid. Not only can this turn into a big job to fix, but a timely and costly one too.

Prevention is crucial, and using a waterproof sealant provides the answer.

Additional benefits to using a concrete waterproof sealant:

Reduce excessive mould and mildew build-up
Water resistance and dampness prevention
Strengthened structure – less moisture, fewer cracks, and less vulnerability to all weather elements
Increased property value – having waterproofed concrete in all the areas of your home or business gives potential buyers the confidence there won’t be any costly maintenance issues
A rich and glossy appearance that looks clean and professional
A finish that helps resist acid, oil, grease, and general stains

What concrete sealer should I use?

The best concrete waterproofing sealer that’s quick and easy to use is our range of Cohe products, including our popular Liquid Rubber Waterproof Sealant.

Installing Liquid Rubber Waterproof Sealant and Liquid Rubber Smooth Coating is simple and easy!

Ensure a clean, dry surface using Cohe Quick Clean.
Bridge joints and cracks with Liquid Rubber Seam Tape.
Apply 1 Layer of Liquid Rubber Primer. 1 litre does 2 square metres. Leave it to dry for 12 hours.
Apply Liquid Rubber Waterproof Sealant using a brush or roller from our Application Kit

Coverage:

apply a minimum final thickness of 1 litre per 1 square meter; it should be around 2-3 heavy coats
20 litre pail will coat up to 40 square meters
for larger areas you can pour out and roll around
Apply the next coat after 12 hours – tacky is okay
Apply above 10 degrees celsius

Do not apply when rain or dew is forecast.

Waterproof your caravan in time for the summer holidays

November 24, 2021 by The Cohe Team

Do you need to waterproof your caravan in time for the summer holidays?

With summer just around the corner, kiwis around the country are gearing up to explore our beautiful outdoors.

But, as many of you will know, travelling with a leaky caravan or RV can dampen your kiwi adventure.

That’s why waterproofing your caravan is vital in making sure you’re prepared for that long-awaited summer holiday!

WHY IT’S IMPORTANT TO WATERPROOF YOUR CARAVAN

Before putting your caravan back out on the road, it’s important to make sure your caravan is waterproofed to endure unexpected weather conditions but also to prevent long-term damage.

Water leaks in a caravan can lead to rotten timber frames, buckling, blistering, and black
mould can form in the lining of the caravan, which poses a potential health risk.

In addition, the interior of your caravan can be damaged. The repair costs will leave you
digging deep into your pocket! To prevent this happening, waterproof your caravan now to
save you time and money in the long run.

HOW TO FIND A LEAK IN YOUR CARAVAN

Finding a leak in your caravan may not be as obvious as you think, especially if you don’t
know what you are looking for.

To start, look for any wear and tear, cracks, thinning, or any other type of damage in the
following places:

Start on the roof and the skylight of your caravan
The water tanks
The water heater and the AC
Check the areas around the doors and windows (generally at the bottom, for signs of water ingress.)
Check the sealing around any items that are attached to the caravan, like the number plates and bike racks

A common way to find a leak is to do a water test. Thoroughly wet your caravan, then watch to see if there is any water seeping through (particularly from the roof and windows).

Signs your caravan could be leaking:

Sounds of water dripping when taps and toiletries are not in use
Water spots, drips, or stains on the walls
Discoloration of the ply
Water spots on the floor inside the caravan
Water spots on the ground outside the caravan

WHAT TO DO WHEN YOU FIND A LEAK

To make sure you have found the source of the leak, do a water test with a hose.

If the leak has been unnoticed for some time, then check for mould, dampness, wood rot and water damage or staining on the ply inside the caravan.

Regular inspection of the seals, at least twice a year, will help to minimize the risk of water
infiltration and leaks in a caravan.

Once the leak is located, make sure the surface is clean and dry before repairing it. If you are going to repair the caravan yourself, don’t resort to silicone cartridges that can be corrosive and eat into the aluminum cladding.

We recommend using a sealant.

There are many sealant products on the market to choose from, and you want to be sure to get it right the first time!

Use a sealant that’s specifically designed for caravans and RVs as this will give you the
confidence to restore and protect your caravan so you can enjoy those summer holidays.

Remodelling your bathroom? Keep everything dry with our waterproofing products!

September 28, 2021 by The Cohe Team

Renovating your bathroom is a great way to spruce up a home – there’s only so many times you can redecorate the living room! But before you start we want to give you some tips about our waterproofing products.

Creating a clean, elegant bathroom where you can relax in the tub, enjoy a hot shower, and have guests use it without feeling embarrassed isn’t as expensive as you think!

Transforming your bathroom on a budget is not only possible but made simple with our waterproofing kit.

Here are some pointers on how to save a few bucks while keeping everything nice and dry.

Paint

Repainting your bathroom is the cheapest and easiest way to give it a make-over.

And a new coat of paint transforms a room making it might the most effective!

Bathrooms work best with neutral colours, so stick to your whites, creams, beiges and light blues. If you feel that’s too bland, accessorise with colour!

Splashes of bright colours – used in moderation – really enhance the personality of a room.

If repainting, think about adding our amazing Liquid Rubber Waterproof Sealant while you’ve got the brushes out.

It can be applied like any normal paint to most common surfaces to waterproof and protect, forming a highly flexible membrane that prevents water infiltration.

This seamlessness means there are no joins, which is where traditional waterproofing methods can fail – perfect for the round edges of a bath!

Tiling

When renovating the bathroom, tiling is probably the thing that’s going to put the cost through the roof.

And there’s a reason for that – it’s difficult!

Doing it right means hiring a professional to do it, so if you really want new tiles in your bathroom, to save money, we suggest limiting the number of tiles used.

Instead of tiling a wall floor to ceiling, only focus on the area you absolutely need tiled, like the floor.

Failing that, a long strip of tiles where the sink is can look great and paint the rest of the room with our waterproof paint.

Grout and Silicone

Grout and silicone hold everything together in a bathroom, preventing water damage and leaking roofs.

The problem comes when they start to get old, dirty and mouldy.

Not only do they look awful, but they’re also unhygienic.

In fact, often it’s the grimy look of grout and silicone that encourages people to renovate their bathrooms in the first place!

A complete bathroom remodelling should involve the removal and reapplication of silicone and grout, but if it’s out of your budget, the next best thing is to give it a good clean.

Our Moss & Mould Kill is a high strength, slow-release cleaner designed to safely treat, remove and prevent moss, mould, mildew, lichen and algae growing on most hard surfaces.

It contains a special blend of biodegradable surfactants to ensure maximum product penetration for improved performance.

Fixtures

If a total bathroom renovation isn’t on the cards, but you want to shake things up a bit, then consider replacing or adding new fixtures.

On a reasonable budget, you can update light fixtures, sink faucets, towel racks, and drawer handles.

These might seem like little things, but it’s the little things that catch your eye when you walk into a room, sometimes subconsciously.

When adding new fixtures, one way to keep them dry is with our Liquid Rubber Seam Tape, used to seal gaps, seams tears and joins.

Cost-effective waterproofing products for a bathroom

We’re all on a budget when it comes to renovations, but remodelling your bathroom should be seen as an investment rather than an expense.

A new-looking room increases the value of your home when it comes time to sell, allowing you to recoup a significant percentage of the initial cost or even make a profit!

Having said that, waterproofing your new bathroom doesn’t have to be expensive.

Our range of waterproofing products is relatively cheap for the incredible job they do.

Whether you’re a DIY enthusiast who wants to give it a go himself or a professional tradesman who needs the right tools for the job, we can help.

Our range of waterproofing products is versatile, environmentally friendly, and affordable for everyone.

Contact us today if you have any questions about our range of waterproofing products or anything else we can help you with.

Our friendly and experienced staff members will be happy to answer any questions you may have.

FAQs about pothole repair – PAR

April 28, 2021 by The Cohe Team

Pothole repair is often a common issue in driveways or pathways or other concrete or asphalt surfaces. Did you know that you can easily DIY your own pothole repair? PAR is perfect for beginners, well-seasoned DIYers, and even professional and commercial use.

Potholes are inconvenient, dangerous and generally slow drivers down especially when you have to drive or walk over them every day. They can cause damage to your car tyres, bike tyres, or cause someone to trip and fall! They also look untidy – but there is good news! They are an easy fix with our great PAR product.

We’ve collected some of the most frequently asked questions about DIY pothole repair, so check them out here:

What causes potholes?

Potholes are a common sight on many roads and driveways around New Zealand. They all vary in shape, size and even depth.

Most potholes are caused by two factors.

Potholes can be formed from environmental factors like water and ground movement, and traffic can cause potholes and cracks in the pavement, roads, or driveways. When either vehicles or foot traffic pass over weak spots regularly, it weakens the asphalt and causes potholes.

Can you fix a pothole yourself?

The answer is yes.

We’ve got a helpful step-by-step process that will help you repair your potholes easily and at a wallet-friendly cost.

Is it easy to fix potholes?

We have chosen to supply the PAR product for pothole repairs because it is simple and easy to use. It’s not just for DIYers but professional and commercial applications too. It is strong, long-lasting, and easy to apply in 3 simple steps.

Step 1: Clean and prep

Step 2: Simply pour the PAR into the pothole.

Step 3: Compact and leave to dry!

Simple… you can repair your potholes yourself. See here for a more detailed instruction list.

Can PAR product be used for concrete or asphalt?

PAR can also be used to repair holes in concrete, but it is recommended that you use MG-KRETE™. This is specifically designed and best used for a concrete application.

When should I fix a pothole?

It’s a good idea to repair a pothole as soon as possible. If left it will continue to get worse and the pothole will likely become larger and more likely to cause damage.

If you have potholes, you can conveniently order our PAR product in our online store.

If I see a crack in my driveway or pavement should I repair that asap?

Yes, it’s a good idea to get onto repairing cracks or fractures in the surfaces before they become potholes.

PAR product is very easy to apply and can be installed during any weather conditions – rain or shine.

How long does it take before I can use an area repaired by PAR?

PAR not only lasts longer than existing pavement, but it also supports traffic immediately following installation. Just cover the patch with powder or sand after installation and you are good to go. You don’t have to wait around for days to use the area.

Why should you use PAR?

PAR is specifically designed and engineered to permanently repair potholes in asphalt in all weather conditions.

All the products we supply and stock have been tried and tested. PAR is proven to work for a variety of different applications.
