Frequently Asked Questions Where can I use Millboard decking? Millboard decking is extremely versatile and can be used in practically every outdoor space to enhance decks, balconies, roof gardens, boardwalks, bridges, pontoons, seating, steps, planters and more. Do I need to seal Millboard decking? No, all Millboard decking is surface-sealed in the factory to ensure they arrive in premium condition. In the first few weeks of use, rainwater will sit on the surface in globules, but don’t worry – this is normal and will stop once the temporary surface seal breaks down. Does Millboard decking mark? The Lastane® finish is highly resistant to scratches, food-and-drink stains, and everyday wear and tear. Sharp objects such as unprotected table or chair legs, spiked shoes or metal planter bases can leave marks if dragged across the surface, so take care when moving these items around. The risk of marking from strong dyes and stains such as berries and animal droppings will be reduced if removed as soon as possible. How do I clean Millboard decking? Because Millboard decking is made of non-porous composite, it resists mossy build-up and stains, so needs very little maintenance. To remove spills and marks, simply use a mild detergent and a brush. Steer clear of solvents, chemicals and abrasive cleaners that could damage your Millboard decking. There’s normally no need for pressure washing. Is Millboard decking slip resistant? Yes, in BS79.76 slip resistance tests, all styles of Millboard decking achieve one of the highest slip-resistant ratings. The unique Lastane® surface – a soft elastomer coating – has been carefully developed to provide a tough surface that greatly enhances slip resistance in wet conditions. Can you recommend an installer? A nationwide network of Approved Installers are available here. Chosen for their professionalism and high quality, you should always follow normal precautions before entering into a contract with a third party, especially if a deposit payment is required. Can I use an impact driver? We advise against using an impact driver to fix the Durafix® screws to the decking as this can break the drive bit and screw head, as well as impede the board from being fixed directly against the subframe. Are Millboard decking colours consistent? As with all flooring, we advise buying all the Millboard decking you need at the same time to help ensure that the colour is as consistent as possible. If you don’t order all your Millboard decking at once, you can blend different batches to create only subtle variation throughout your space. Can Millboard decking be cut just like wood? Millboard decking can be cut with standard saw blades, although we recommend a carbon-tipped, multi-purpose chop saw. As the formed end of the board is lost when cut, these can be placed in less visual areas against a wall or edging profile. Matching Touch-up Coating for exposed ends is available to buy separately. What fixings should be used to fix Millboard decking? Following extensive trials, we recommend and supply Durafix® stainless steel screws, designed specifically for Millboard. There’s no need to pre-drill or countersink Millboard decking, and the unique Lastane® material self-heals, leaving only a virtually indistinguishable mark on the surface. What if it snows or is icy? A small amount of granulated white salt can be used to keep your Millboard decking ice-free. Please don’t use rock salt, as this contains clay and grit and can be abrasive. When winter’s over, clean the surface with soapy water and a soft broom. What sub-frame base system should be used with Millboard decking? The ideal companion is our all-weather composite decking is Plas-Pro, a durable, hard-wearing and practical sub-frame material for spaces exposed to damp such as jetties, fishing platforms, pools, roof terraces and boardwalks. The Plas-Pro Millboard sub-frame system is made from 100% recycled plastic, which means it won’t rot, split or crack. Does Millboard decking get hot in the sun? CAUTION – In high temperatures or prolonged bright sunlight Millboard decking can become hot. Please exercise caution before walking barefoot on to Millboard decking in circumstances where the decking is in high temperatures and exposed to sunlight. In these circumstances, it may be necessary to use footwear. Special caution should be taken when using Millboard decking in areas where there is heat/UV reflective glass. Does Millboard decking come with a warranty? Yes. Our warranty gives you peace of mind that we will stand by our word and will hold to the conditions as laid down in the warranty document. We will issue you with either a 25 year Residential Warranty or a 5 year Limited Warranty depending on the installation application of the boards and when it is registered within 90 days of the installation.

Can I use a fire pit / bowl or patio heater on my deck? In instances where there is burning wood or coal they will need to sit the fire bowl / brazier onto a porcelain or cement tile / slab. The slabbed area needs to extend about 1m outside the fire bowl / brazier. Any embers or burning material needs to be removed immediately to prevent any damage or lasting marks to the Millboard surface. Patio heaters or infra red heaters are not know to affect the Millboard. What is the different between Timber Joists and Composite Joists? Timber is the most commonly used sub frame material, and most have a 15 year warranty. However this is only under ideal circumstances and if the cut elements are retreated. In applications where the timber is in contact with the ground or has limited airflow then this will impede on the durability, and in some cases reducing it down to 1/3 or it’s intended lifespan. At Millboard we recommend to use a wood free alternative to maximise the durability of your sub frame system. We have provided the Plas-Pro system, and 100% recycled plastic non-rot profile. When using this as an alternative to timber bear in mind that the structural spans are not equivalent. Please refer to the Plas-Pro brochure or Installation Guide for further details. If in doubt then contact a member of our technical team on firstname.lastname@example.org. Fire Safety use as Decking Boards and certification and testing has been to this end. Millboard decking has been tested to BS EN ISO 13501-1:2007+A1:2009 and has a Bfl-S1 reaction to fire classification (fire test for flooring). Millboard decking is not recommended for use as cladding on buildings 18m (6 storeys) or above, and for other cladding use, it should be subject to Building Regulations to check suitability, use and proximity. For a full Fire Safety report go to www.millboard.co.uk/help-advice/downloadable-guides/ Can I use a standard board as an edging piece? Yes you can, where the edge is merely aesthetic, such as a balcony edge, if this is your preferred finishing option. However, where the edge is likely to sustain impact, such as a step, we do not recommend using a standard board. Our edging boards have been specifically designed with high impact in mind and as such have a thicker Lastane® surface to withstand the knocks and scrapes associated with step edges and other associated applications. My boards have just been laid and have a slight oily / shiny finish? As the boards are a moulded product we use a release agent in the manufacturing process so when the boards are first delivered this release agent is still on the surface. This may result in the boards looking like they have a shiny or waxed surface or have small particles of dirt and water puddling which could cause slip issues. This release agent will come off the surface within 6-8 weeks due to natural weathering. This process can be accelerated by cleaning the boards with warm soapy water and stiff brush after installation. What tolerances should be allowed? There will always be a slight variance in the board’s dimensions due to the fact that we mould from natural oak, and due to the pressure of the foam. Despite this we calibrate the boards to maintain as consistent a profile as possible. The tolerances to allow are: Width: ± 3mm. Length: ± 5mm. Thickness: ± 2mm The dimensions of the Weathered Oak style may vary more between moulds due to the fact that they are moulded from timeworn oak with minimal changes to the dimensions. Can you use it for load bearing applications (i.e. structural)? It is not recommended to use Millboard in structural applications. Millboard decking would need to be fixed to a structural frame, either made of timber or ‘Plas-pro’ recycled plastic. Can you paint/stain it? No, it is not needed! Durable, through-body coloured and UV stable, Millboard is a low maintenance product that does not require a protective coating. Paints and stains will not properly adhere to the surface.
