Cladco Signature Composite Wall Cladding Installation Guide

Installation Guide, Aftercare and FAQS

Important Advice Prior to Installation

BEFORE INSTALLATION

For a balanced and visually appealing result, we recommend laying out all composite boards prior to installation. This will help evenly distribute the natural tonal variations across the product.

Storage, Handling, Colour and Health & Safety

Storage and Handling

Cladco Signature composite wall cladding boards should always be stored in a cool shaded spot, on a flat and level surface which supports the whole length of the boards. It is recommended to store the boards on a pallet to ensure they are not sat directly on wet or cold ground.

Wear protective gloves when handling the boards and take care when lifting them. We recommend that a minimum of two physically capable persons carry the boards.

COLOUR

Both our 3.6m Signature composite cladding and 3.6m Signature woodgrain composite cladding boards are designed and manufactured to replicate the natural variants of timber cladding.

It’s recommended to purchase all boards required for the project at the same time, as this will ensure colour consistency and only one delivery cost. We recommend laying out all the boards before installation to ensure a natural effect of grain and colour tone is balanced across the whole of your cladding. As with all materials exposed to direct sunlight, some natural weathering will occur over time.

HEALTH & SAFETY

Cladco composite wall cladding are supplied with a 10 year warranty, subject to terms and conditions. Cladco wall cladding boards should be installed as per this installation guide, and failure to do so may invalidate the warranty.

For further information, see our terms and conditions.

Tools and Equipment

Protective Equipment

When handling or carrying cladding boards it is advised to wear long sleeves and gloves. When cutting the boards, we suggest wearing a protective dust mask, ear defenders and safety glasses.

Tool Set

Standard everyday carpentry tools will be needed to complete the installation, including a tape measure, pencil, spacing tools and stanley knife.

Spirit Level And String

A spirit level is essential when installing your battens to ensure a level support system.

Power Drill Or Driver

Standard power drills can be used when installing Signature composite wall cladding boards.

Jigsaw Or Handsaw

Composite wall cladding boards can be cut using any standard wood cutting tools. We recommend using a fine-toothed blade to get the cleanest finish to your cut edge.

Preparing a Gable End

If your home has a gable end, battens must be spaced up to 500mm apart with additional, shorter supporting battens installed every 200mm, going up and down the apex (the triangular shape of your gable end). This ensures that the composite boards are fully supported across the entire build.

Ensure all battens are level using either a tape measure or a spirit level before installing boards. When installing 30mm x 50mm composite battens flush to the wall, be sure to leave an adequate ventilation gap between the wall and the composite cladding boards to allow air to flow. Check your wall is stable and secure before pre-drilling 6mm holes.

DOORS AND FIXTURES

As a flexible composite cladding board, wall fixings such as exterior lights can be worked into the exterior just as easy as using timber cladding.

Composite wall cladding and composite corner trims can be worked around wall fixings, doors and windows easily using normal woodworking tools. This allows for additional features, such as exterior garden lights, to be added into your design for a professional finish.

AIRFLOW

Please do not completely seal your installation to allow some air to flow between the cladding boards and the surface below when fitting the trims. Allow for a 10mm air gap between the cladding boards and the base of the installation.

1

You will need to pre-drill the battens and the surface below using a 6mm drill bit. The battens are 30mm high and you will need to secure them at least 50mm into the surface below. You will need to choose fixings suitable for the surface you are fixing into. Screws should be 5-6mm diameter and at least 80mm long (Please note: Cladco do not provide the fixings and screws for your installation).

2

Battens should be attached to the surface at a maximum distance of 500mm apart. The battens will need to run the entire length of the area being clad, adding in additional battens at any point where you will need to join two cladding boards end to end. Remember to install your battens at a 90-degree angle to the way that you want your wall cladding boards to run. Battens should be 50mm wide x 30mm high and should be fully supported once installed. It is important that the surface below the battens is flat and stable.

3

Attach a starter strip to the bottom of each batten. This will give the first cladding board something to sit on. You will need to pre-drill a pilot hole into the composite batten and attach the starter strip using a screw that is at least 15mm long.

Ensure that each strip is level with the next and that the first board sits level on the strips before continuing to the next step.

EXTREME TEMPERATURES

Extreme temperature changes could cause the boards to expand or contract. Ensure boards have had sufficient time to acclimatise to the temperature before installing. Do not install in extreme temperatures.


CUTTING

If boards need to be cut to size, ensure the boards are installed and secured immediately after cutting.

4

Place the first wall cladding board on to the starter strips. Mark and then pre-drill pilot holes through the fixing groove of the board into the batten below.

Secure the boards using M4x40mm screws, ensuring that the board is fastened securely on each batten that it touches. Secure these fixings by hand, as is important not to over-tighten the screws and risk splitting the board.

Please Note: M4x40mm screws must be used, not doing so will invalidate the products warranty.

5

Slot the second board onto the first and repeat the fixing process ensuring that the second board is fitted securely in place on each batten.

Repeat this process with each board until you reach the required height. Ensure that the section between the battens remains empty to allow air to flow beneath the boards.

6

When butting two boards together, you should use a mitered edge
 for a neat finish. The most common miter angle is 45 degrees.

As the cuts are angled, you’ll have one side of the wood longer than the other. You’ll need to keep track of which side will be which and make your measurements correctly.

7

Set the miter saw to the angle it will need to cut. Use the included instructions for your machine, as each is different. Set the pieces side by side to ensure a neat joint. Screw the wall cladding through the top and into the batten.

8

Continue to fit the cladding boards in this manner until you have completely covered the area you want.

It is possible to fit your boards side by side by simply butting the two ends up together. You may need to install more battens if you wish to do this, as each board will need to be supported on a batten where it meets the next board.

WOODGRAIN EFFECT CLADDING

Did you know Cladco Signature composite wall cladding also comes in a woodgrain finish? With eight colours available, you can achieve the look of authentic woodgrain cladding to complement or contrast your space.

1

It is recommended that the battens used to support your Cladco wall cladding are made from a composite material, which helps to maximise the long term performance of your cladding.

Alternatively, you can use wooden battens to support your cladding following the same fitting process as you would for composite battens.

2

You will need to pre-drill the battens and the surface below using a 6mm drill bit. Cladco Signature composite battens are 30mm high and you will need to secure them at least 50mm into the surface below. You will need to choose fixings suitable for the surface you are fixing into. Screws should be 5-6mm diameter and at least 80mm long. (Please Note: Cladco do not provide the fixings and screws for your installation.)

3

Battens should be attached to the surface at a maximum distance of 500mm apart. The battens will need to run the entire length of the area being clad, adding in additional battens at any point where you will need to join two cladding boards end to end. Remember to install your battens at a 90 degree angle to the way that you want your wall cladding boards to run. It is important that the surface below the battens is flat and stable.

4

Attach a starter strip to the right side of each batten, as this will give the first cladding board something to sit on. You may wish to pre-drill a pilot hole into the composite batten and attach the starter strip using a screw that is at least 15mm long. Ensure that each strip is level with the next and that the first board sits level on the strips before continuing to the next step.

EXTREME TEMPERATURES

Extreme temperature changes could cause the boards to expand or contract. Ensure boards have had sufficient time to acclimatise to the temperature before installing. Do not install in extreme temperatures.


CUTTING

If boards need to be cut to size, ensure the boards are installed and secured immediately after cutting.

5

Place the first wall cladding board on to the starter strips. Mark and then pre-drill pilot holes through the fixing groove of the board into the composite batten below. Secure the boards using M4x40mm scews, ensuring that the board is fastened securely on each batten that it touches. Secure these fixings by hand, as it is important not to over-tighten the screws and risk splitting the board.

Please Note: M4x40mm screws must be used, not doing so will invalidate the products warranty.

6

Ensure that the section between the battens remains empty allowing air to flow beneath the boards. Slot the second board onto the first and repeat the fixing process ensuring that the second board is fitted securely in place on each batten.

7

It is possible to fit your boards side by side by simply butting the two ends up together. You may need to install more battens if you wish to do this, as each board will need to be supported on a batten where it meets the next board. Continue to fit the cladding boards in this manner until you have completely covered the area you want.

8

Depending on your installation, you may want to finish off the edges using trims to give you a lasting professional look. There are a range of trims available in all colours to complement your cladding boards, which can be secured to your installation by glue.

Finishing Your Wall Cladding

Whether you have installed Signature composite wall cladding vertically or horizontally, you can use matching composite corner trims to complete the look of your project for a professional touch.

Composite corner trims can be worked into your installation easily using normal woodworking tools and Cladco high strength adhesive.

Installing corner trims is the last phase of the project. Install Signature composite wall cladding as above right up to any windows or doors.


Take the corner trim and measure the length of the area it’s going to be fitted on, for example, the width and height of a door or window. Corner trims can be cut to length and worked just like timber. If placing two trims side by side, these can either be mitered to create a neat angle, or cut to fit.

Once the corner trim is cut to size, you can use Cladco adhesive along one or both sides of the corner trim to attach it to the edge of the cladding.


To allow for expansion you may wish to only glue the top edge. Once installed, you can then cut and place the second piece of trim along the edge until you have the desired finished look.

Aftercare and Maintenance

MAINTAINING YOUR COMPOSITE CLADDING

For standard everyday maintenance, such as clearing plants and leaves, brush your cladding boards using a stiff bristled brush.

To remove any dirt, grime or animal droppings, for example, Signature composite cladding boards can be washed using warm, soapy water and a sponge when needed. This will ensure your cladding will look its best for years to come.

Cladco composite cladding products require very little maintenance once installed. Composite cladding is also rot and weather resistant, and unlike traditional timber materials, composite cladding products do not need to be painted or stained.

FAQs

As our composite cladding boards contain wood, they are not fire rated.

No, composite cladding does not need to be painted. The boards are manufactured with colour integrated throughout, so they arrive ready to install with no sanding, staining, or painting required. Both Signature and ProClad composite cladding are designed to maintain their appearance with minimal upkeep, making them a low‑maintenance alternative to traditional timber.

Cladco composite cladding is an excellent choice for exterior domestic projects. Please be aware that it is the responsibility of the customer to ensure that the product complies with relevant building standards and regulations. We cannot assume any liability should the products fail to meet specific building, fire, structural, or other legal requirements applicable to your intended use or installation.

Composite cladding needs significantly less upkeep than traditional timber, but it isn’t completely maintenance‑free. Over time, exterior surfaces naturally accumulate dirt, debris, and environmental build‑up, and routine cleaning helps keep the boards looking their best.

Regularly brush away loose debris and rinse the surface with clean water. If your cladding is installed near overhanging trees, clear leaves, petals, and sap promptly to avoid surface marks. Water runoff from gutters or downpipes can also leave stains, so it’s important to check these areas and clean as needed.

For more stubborn dirt, warm soapy water can be used to clean the boards effectively. With simple periodic maintenance, both Signature and ProClad cladding will maintain their appearance and performance for years to come.

Watermarks can occur during the natural weathering process of composite cladding. With Signature composite boards, this is more common due to the release of tannins from the recycled timber content, which can make water marks appear more visible at first. This is a normal part of the settling process and will fade naturally over time.

ProClad composite boards, which feature a capped polymer surface, are less prone to visible watermarks. However, as with any exterior material, slight marking may still occur depending on environmental conditions. These marks are typically temporary and diminish as the boards weather.

Like any composite material, our Signature composite cladding boards go through a process of stabilisation where fading may happen until the final colour is reached. Stabilisation usually occurs during the first six months following installation. This is more evident in the woodgrain design, where shading variations can arise due to the process of sanding.

Composite boards are designed to be durable and offer good resistance to everyday wear, including minor scratching. However, no cladding or decking product is completely scratch‑proof. Lighter surface marks can occur from impacts, sharp objects or abrasive materials.

Capped composite boards, such as ProClad, have an additional protective outer layer that provides enhanced scratch resistance compared to uncapped options. Signature boards are also robust, but as they have an exposed composite surface, they may show marks more easily.

In most cases, light scratches will become less noticeable over time as the boards naturally weather. Regular cleaning and avoiding sharp or abrasive contact will help maintain the best appearance.

Both Signature and ProClad composite cladding require adequate airflow behind the boards. Creating a ventilated cavity allows any rainwater that penetrates the cladding to drain and evaporate effectively. Ensuring the correct spacing at the board ends and around the installation perimeter helps maintain airflow and reduces the risk of moisture‑related issues, such as mould or discolouration.

In most cases, planning permission is not required to install cladding on your home, as long as the materials do not significantly alter the external appearance of the property.

However, if your property is listed or located in a conservation area, you may need permission before proceeding. Please note that Cladco cannot provide official planning advice. We recommend consulting a licensed planning consultant or building surveyor before beginning your installation.

Darker colours can sometimes appear lower‑maintenance because they tend to hide marks and everyday dirt more easily than lighter shades. However, all colours will naturally weather over time, and the level of care required is generally similar regardless of the shade.

Yes, you can use a pressure washer on our composite products, but we recommend keeping the pressure below 2,000 PSI and using a fan tip with a 40–60° spray angle. Maintain a distance of 250–300mm from the surface at all times, and always test on a small, inconspicuous area first. Avoid prolonged direct contact, as this may damage the surface of the panels.

Composite products are made from a blend of recycled materials designed to offer the look of timber with enhanced durability and reduced maintenance. Most boards combine recycled wood fibres with recycled plastics to create a strong, long‑lasting core that performs well in a range of environments.

our ProRange composite products feature an additional capped polymer shell. This protective layer improves resistance to weathering, scratches, stains and UV fading, helping the boards maintain their appearance over time. Surface finishes can vary—from smooth and contemporary profiles to detailed woodgrain effects that replicate the look and feel of natural timber.

Across the range, composite boards and panels are available in multiple colours and finishes, and they don’t require sanding, varnishing or painting - making them a low‑maintenance alternative to traditional timber.

Cladco composite cladding is designed primarily for exterior use, but it can be installed indoors in certain situations. If used inside, it’s important to ensure the space has suitable ventilation and that the boards are fixed to an appropriate substructure. As with any installation, the boards should be fitted with the correct clearances and spacing to allow for natural expansion and contraction.

Many customers choose to use composite cladding indoors for feature walls or decorative finishes, but it’s always best to check that the environment is dry, stable, and free from excessive heat or moisture before installation.

Mould or mildew can develop on any exterior surface due to airborne spores. If it appears on your decking or cladding, clean the affected area with warm soapy water or a suitable outdoor cleaner.

Good installation practices also help reduce the likelihood of future build‑up. Ensuring proper airflow and ventilation behind cladding, and maintaining the correct spacing between decking boards, allows moisture to escape and keeps surfaces drier.

Regular inspections and occasional cleaning will help maintain the appearance and longevity of both decking and cladding.
