The Ultimate Anti-Slip Inserts for Slippery Grooved Decking

Why is timber decking slippery?

When decking gets damp, wet or frosty, it can become slippery 

Timber decking is naturally porous enough that it doesn’t get slick when it’s wet – at least not at first. However, fungus and algae can quickly grow on untreated decking, if it has been left damp for sometime. The fungus or algae can be barely noticeable when it’s dry, but when its wet it can be like ice. Grooved decking can help rain water run off decking, helping it stay dry, but the grooves can also trap moisture, grease and dirt, which will only make matters worse.

One solution is to pressure wash your decking or scrub it with a chlorine bleach/ water mix to remove that fungus but do be careful not to damage it or your surrounding plants. Once you have your decking clean and dry, you can look at treating it with a penetrating oil preservative.

But its hard to dry out your decking when its raining cats and dogs out there!

Scrub, power wash and repeat

If you manage to dry and treat your decking, you must be sure to repeat every time the algae comes back and still be very careful when your decking gets wet. If painting your deck, do be careful as a heavy coat of paint can be just as slick as the fungus / algae when wet.

There are better ways – RetroGrip®

The simplest solution, requiring the least amount of ongoing care will be to drop a RetroGrip® insert into your grooves. RetroGrip will last for years and keep you safe on your feet, what ever the weather.
