How to Maintain and Care for Decking Strips

Decking strips are a key component of outdoor and, in many cases, indoor decks, providing increased safety in the form of slip resistance and additional durability for the high-traffic areas. Whether timber, composite, or anti-slip GRP (glass-reinforced plastic) Decking Strips need to be maintained properly to prevent their functionality as well as aesthetics from becoming compromised.

Why Is Maintenance Important?

A handy thought prior to letting you know how is to explain why proper decking strip maintenance is so important:

Safety: Dirt and algae accumulation reduce the anti-slip effectiveness of the strips, making the surfaces dangerous.

Aesthetics: Well-maintained, clean strips enhance your deck's appearance and avoid the staining or discoloration.

General Maintenance Routine

Regular Cleaning

Periodic cleaning forms the basis of decking strip maintenance.

Materials Needed

• Soft-bristle broom or brush

• Garden hose or pressure washer (cautiously)

• Mild detergent or decking cleaner

Bucket

Textured areas and grooves: scrub brush

Steps

Sweep Frequently: Sweep the deck every week to clean leaves, dirt, and debris between or below the strips.

Rinse Down: Hose off loose dirt.

Apply Cleaning Solution: Combine warm water with the mild detergent and apply using a mop or brush.

Tip: Refrain from using harsh chemicals such as bleach on timber or the composite decking strips since they wear out the surface and compromise the life of the strip.

Deep Cleaning (Seasonal)

Deep cleaning must be done at least two times a year, in spring and autumn.

Additional Steps

• For algae or moss, use a specialized deck cleaner or white vinegar diluted with water.

• For GRP Anti Slip Strips For Decking, pressure wash on low power at least 12 inches from the strip to avoid damaging it.

• For wooden strips, avoid exposing the surface to excessive water immersion and avoid soaking.

Material-Specific Care Advice

Timber Decking Strips

Care Advice

• Re-oil or seal annually with a decking oil to protect against the moisture and UV damage.

• Sand very lightly and reseal if needed.

• Inspect fasteners and screws for rust and replace them with stainless steel if needed.

• Do not let water or snow sit on the deck, this encourages rotation.

Composite Decking Strips

Tips for Maintenance

• Avoid using harsh chemicals; these will break down the polymer in the strips.

• Remove stains (e.g., grease or wine) at once to avoid absorption.

• Clean with soft equipment (no metal scrapers), and do not scratch the surface.

• Avoid extended exposure to static waterfit suitable drainage if needed.

GRP (Fiberglass) Anti-Slip Strips

GRP decking strips are often used for industrial, commercial, or heavy domestic use because they are weatherproof and highly resistant.

Care Tips

• Regular washing in warm soapy water will maintain the grit surface performance.

• Harsh stains can be removed using a degreaser or GRP-friendly cleaner.

• For industrial use, use a steam cleaner (within the recommended temperature range).

Preventive Maintenance

Routine Inspections

• Check your decking strips every 23 months:

• Search for loose screws, broken strips, or swollen edges.

• Moss, Algae & Mold Prevention.

• Moss and algae render slippery and degraded the materials.

Prevention Strategies

• Provide your deck with enough sunlight and air.

• Cut close-growing plants near the deck that cast a shadow on the deck.

• Treat wood or composite surfaces with algae-resistant paint.

• Apply preventive anti-fungal or anti-algae treatment once a year.

Repair and Replacement

With even the best care, decking strips can deteriorate over time.

When to Repair

GRP strips with slight edge lifting: reattach with adhesive.

Loose fasteners: tighten them or replace them with corrosion-proof fasteners.

When to Replace

• Splintered, rotten, or warped wooden strips.

• Heavily cracked composite strips.

• Worn GRP strips where grit is smoothed and anti-slip are gone.

Storage & Covering

If your deck is not used during winter months:

• Use ventilating covers that are rain- and snow-proof.

• Don't put plastic tarps directly on wood, their water buildup encourages mildew.

• Run-off water buildup using a sloping cover or canopy, if possible.

Maintenance of decking strips is essential to the longevity and safety of your deck. You're working with natural wood, engineered composite, or industrial-grade GRPa little TLC never hurts. With the addition of cleaning and the inspection routine in place and the precautions taken through the cycles of seasons, you can safeguard your investment and have a safe and beautiful deck throughout the year.
