Millboards are 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.
A small amount of granulated white salt can be used to keep your Millboard 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.
The Lastane® finish is highly resistant to scratches and 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.
Because Millboard is made of non-porous composite, it resists mossy build-up stains, so needs very little maintenance. To remove spills and marks, simply use a mild detergent and a cloth. Just steer clear of solvents, chemicals and abrasive cleaners that could damage your Millboard – and there’s normally no need for pressure washing.
