Perfect for a range of substrates, including metals, wood, plastic, concrete, and more, this white adhesive sealant possesses excellent bonding strength, UV resistance and anti-mould properties. This will ensure a long-lasting bond even when exposed to the elements.

For a controlled and mess-free application, we recommend you use a Sealant Gun. Please note that the nozzle on this adhesive is flat, rather than a V cut.
Make sure you consult the technical datasheet for specific details and apply usual industrial hygiene during use. If you are unsure of material compatibility, we recommend you complete your own testing.

For your Fencing project, square meterage is calculated by multiplying the total height of your fence by the total length of the boundary being fenced.
As each Composite Fencing Panel provides 0.72m coverage once installed, divide the square meterage by 0.72 to work out the total number of Panels required for your Fencing project.
Please note that our Composite Fencing Posts measure three metres in height, and, once installed, will allow for a maximum height of two metres, which equates to ten Panels.

Customer Collection Notice
Please ensure you have pre-booked your collection slot before travelling to site.
When arriving to collect your order, please report to a member of our Warehouse Team who will register your arrival and locate your goods. Once ready, your items will be picked and brought to your vehicle loading area.
During busy periods, there may be a short wait while our yard team assist other customers or complete other loading tasks. We always do our best to work within your booked collection time.
We respectfully draw your attention to the following important points:
- Loading is ultimately the customer’s responsibility. While our team can assist with mechanical loading using forklifts, we cannot handball items into enclosed vehicles. Customers must ensure their vehicle is suitable and that goods are safely loaded and adequately secured before leaving the premises.
- Sharp sheeting, metal goods, and long/heavy items may pose additional handling risks. Please come prepared with high-quality protective gloves, and any appropriate protection materials to avoid damage to your vehicle or restraints (e.g. ropes or straps). The edges of roofing sheets and metal products can be extremely sharp, and care should be taken when handling.
- We strongly recommend that customers bring their own straps, ropes, or other securing materials, as we are unable to provide these at the point of collection.
- If you are unsure of your vehicle’s load capacity, we can advise the approximate weight of your order in advance. It is your responsibility to ensure your vehicle is suitable for transporting the goods safely and legally.
- Cladco will not be held liable for any damage to your vehicle or goods once they have been loaded and leave our premises. Loading assistance is provided entirely at the customer’s own risk.
Click & Collect – Pre-Booking Required
You are welcome to collect your order from either our Okehampton (Devon) or Andover (Hampshire) site. All collections must be pre-booked in advance so your items can be picked, packed and ready for you.
Please do not travel to site without a confirmed collection time, as we cannot guarantee your order will be available.
Once your items are ready, you will receive an email with a link to book your collection slot. Please note, same-day collections are not available and bookings must be made at least two hours in advance.
When you arrive, please bring your order confirmation and follow the signage to the collection area where a member of our team will assist you.
