How To Clean Decking

How To

The decking is an ideal spot to unwind or entertain, but the unpredictability of the British weather means it is in need of some TLC every now and then. There is nothing more uninviting than decks covered in debris, dirt and grime so bring warmth to your decking area by making it aesthetically pleasing as well as safe to stand on.

We at ROCOL supply a range of high-performance cleaners and anti-slip products which are extremely hard-wearing and will ensure your decking is sparkling clean and equipped to withstand heavy pedestrian traffic. In most instances, a forceful sweep is sufficient to keep your decking looking respectable, but a thorough scrub twice a year will add to the longevity of your decking and keep it in great condition.

When selecting the ideal time for this comprehensive process, B&Q recommend you carry out this practice in the spring to prepare for the summer season, as well as in autumn ahead of the imminent winter months. Avoid treating your deck in extreme heat as this can cause the cleaning solution to dry rapidly and not be fully absorbed into the wood. By following these five simple steps, your decking will soon be restored back to life.

Step One: Clearing the Deck

Cleaning your deck will only be efficient if you have a clear space to work in. Anything from potted plants to furniture need to be removed so that you have unrestricted access to every decking board.

Step Two: Sweep Away Dirt and Foliage

Brush the deck down with a soft brush and remove any leaves or dirt that are present on the wooden surface. This will prevent particles from flourishing and causing harm to the deck. You should then use a stiff-bristled broom and some water to scour in between the grooves.

Step Three: Use A Pressure Washer

Set the pressure to a minimal level and wash away any remaining grime. Do not hold the pressure washer in close proximity to the wood as you could crack or damage it. It is recommended for safety reasons that you wear closed shoes, safety glasses and earmuffs for this part. Remember to be mindful of your footing as the decking may also become slippery. If you do not have access to a pressure washer, then a hose will be just as proficient.

Step Four: Apply the Decking Cleaner

A decking cleaner and reviver is specially formulated to recondition the wood and bring it back to its natural colour. As well as reinvigorating the appearance of your deck, it will also remove moss, mould and algae, and simplify the application of deck paint, stains and oils.

Follow the recommended instructions supplied with your cleaner when it comes to applying your solution. As soon as the solution comes into contact with the surface, begin scrubbing it with a scrubbing brush.

Starting at one end of the deck, work in small, manageable areas (around three to four deck boards) so that each board receives a rigorous cleanse and don’t forget to rub it into the grooves. This will also help avoid spotting which is caused by mould from most types of wood.

Once you have scrubbed the entire deck, leave it to dry for 15-20 minutes. It is advisable when using cleaning chemicals to wear suitable protective gear including gloves and goggles.

Step Five: Rinse The Deck

After you have left the solution for no more than 20 minutes, return to the pressure washer and rinse off the cleaning mixture along with any excess dirt that is still visible. A garden hose can once again be used as a reliable alternative. If required, allow the deck boards to dry for at least 24 hours before applying any paint or stain.

Step Six: Apply Anti-Slip

Once the desk has been rinsed, we advise applying an anti-slip treatment. Coating a surface in a safe covering like this will protect those who walk over the surface in most types of weather. Here at Rocol, we provide a SAFE STEP Anti-Slip Spray that is quick-fix and transparent that is suitable for both interior and exterior use.
