Anti Slip Decking

Safer Outdoor Surfaces Year-Round with Premium Anti Slip Decking

Decking looks great until the weather turns. Rain, morning dew, algae and moss build-up can all leave timber, composite and concrete decking dangerously slippery, especially around pools, balconies, walkways and communal outdoor areas. Our high-quality Non Slip 21 treatment tackles this directly, chemically bonding with the surface to restore grip without altering the colour, texture or appearance of your decking.

Whether you’re managing a commercial property, a hospitality venue or a private garden, anti slip decking treatment is one of the simplest ways to reduce slip risk and protect the people using your outdoor space.

 

Anti Slip Decking Treatment for Every Surface

Timber decking
Timber is the most common decking material we treat. Our anti slip decking treatment penetrates the surface to improve grip while allowing the wood to retain its natural appearance and texture.

Composite decking
Composite decking can still become slippery when wet, particularly on boards with a smoother finish. We apply a treatment suited to composite surfaces that improves traction without affecting the manufacturer’s warranty or finish.

Concrete decking

Concrete and paved decking areas around pools, patios and communal spaces benefit from the same treatment approach, restoring grip on a surface that’s often walked on with bare or wet feet.

Why Does Decking Become Slippery?

Outdoor decking is constantly exposed to the elements.

Moisture, shade and organic debris create the conditions for algae and moss to take hold, and even a thin, near-invisible layer can dramatically reduce surface grip. Timber decking is particularly prone to this, but composite and concrete surfaces are not immune, especially in areas with heavy foot traffic or limited drainage. Left untreated, this build-up becomes a recurring slip hazard rather than a one-off problem.

 

Our Anti Slip Decking Process

  1. Inspection and clean
    We start with a thorough pressure wash of the decking to remove dirt, algae, moss and general surface debris. This step is essential, as the treatment needs a clean surface to bond effectively.
  2. Treatment application
    Once the decking is clean and dry, we apply our Non Slip 21 treatment. It works at a microscopic level, creating a durable non-slip finish that improves grip even in wet or damp conditions.
  3. Result
    The finished surface looks the same as before treatment, with no visible coating, film or colour change, but with significantly improved slip resistance underfoot.

 

 

Anti Deck Slipping Frequently Asked Questions

Will anti slip decking treatment change how my decking looks?
No. The treatment works invisibly, bonding with the surface without adding a coating, film or colour change.

Can composite decking be treated as well as timber?
Yes. We treat timber, composite and concrete decking, adjusting the approach for each surface type.

Do I need to have my decking professionally cleaned first?
Cleaning is included as part of our process. We pressure wash the decking before treatment to make sure the surface is free of dirt, moss and algae, which helps the treatment bond properly.
