What is Anti-Slip Tape?

Anti-slip tape is a pressure-sensitive adhesive strip with an abrasive grit surface that bonds directly to floors, stairs, ramps, platforms and any surface presenting a slip hazard. Unlike permanent nosings or coatings, it requires no specialist tools, no drying time and no structural modification to the surface — clean the area, peel the backing, press the tape down and it is immediately ready for use.

This black anti-slip tape uses a silicon carbide grit surface, which is harder and sharper than the aluminium oxide grit found on cheaper alternatives. Silicon carbide maintains its cutting-edge texture significantly longer under foot traffic, UV exposure and wet conditions, delivering consistent friction performance throughout the tape's working life. The black colour provides a discreet, professional appearance that suits domestic stairs and commercial floors without the high-visibility yellow hazard-warning aesthetic.

Silicon Carbide vs Aluminium Oxide — Why It Matters

Most budget anti-slip tape uses aluminium oxide grit. Silicon carbide — the material in this tape — is significantly harder (9.5 on the Mohs scale vs 9 for aluminium oxide) and has sharper angular grain edges that bite into footwear soles more aggressively. In practical terms this means two things: better initial grip performance, and longer service life before the grit rounds off and loses effectiveness. In high-footfall commercial environments this difference is significant. For domestic use, both materials are adequate — but silicon carbide provides more grip per square millimetre and lasts longer before replacement is needed.

Key Features and Benefits

• Instant installation — no tools, no trades — peel the backing liner, press down, apply firm pressure along the full length. Walk on immediately. No adhesive to mix, no tools to hire, no drying time to wait for.
• 18.3m roll — exceptional value coverage — a single 50mm roll provides approximately 24 strips at standard 750mm stair width, covering a complete domestic staircase of 13–14 steps with spare material for additional areas.
• Scissors-cut to any length — standard household scissors cut cleanly through the tape at any point. No specialist cutting equipment needed.
• Performs in wet and oily conditions — the silicon carbide grit maintains grip even on wet, greasy or contaminated surfaces — making it suitable for industrial environments, kitchens, loading bays and outdoor areas where aluminium oxide alternatives can lose effectiveness when wet.
• Edge sealer recommended for external use — applying anti-slip tape edge sealer to the long edges of the tape (sold separately) prevents water ingress under the adhesive and significantly extends service life in exposed outdoor installations.
• Primer recommended on porous surfaces — for concrete, stone or porous surfaces where the adhesive may struggle to grip, applying anti-slip floor primer (sold separately) to the substrate first dramatically improves adhesion and long-term bond strength.

Where to Use

• Domestic stairs — stair tread nosing strips on wooden, tiled or carpeted steps
• Outdoor steps and ramps — garden steps, concrete ramps, covered entrance steps
• Industrial walkways and loading bays — warehouse floors, dock edges, pallet ramps
• Commercial kitchens and food production — wet, greasy floors requiring maximum grip
• Pool surrounds and leisure centres — wet-area non-slip marking
• Vehicle ramps and access areas — hand-laid strips for grip on metal or concrete ramps
• Ladders and access platforms — grip strips on ladder rungs and platform edges
• Marine and offshore — deck grip on boats, pontoons and marina structures

⚠️ Note: Anti-slip tape is a short-to-medium-term solution for moderate footfall. For high-traffic commercial or industrial environments where permanent, long-life step edge protection is required, consider GRP stair nosings or GRP anti-slip strips, which provide superior durability and a service life in excess of 10 years.

How to Install

1. Clean the surface. The surface must be completely clean, dry and free from dust, grease, oil and any existing coatings. Use a degreaser on oily surfaces and allow to dry. For porous substrates (concrete, stone), apply anti-slip primer and allow to fully dry before applying tape.
2. Measure and cut to length. Measure the required length and cut the tape with sharp scissors, cutting squarely across the tape. For stair treads, cut to stair width less 10mm each side to avoid the tape overlapping the edge.
3. Peel the backing. Peel the release liner from the back of the tape starting from one end. Fold the liner back on itself as you peel to make it easier to handle.
4. Apply to surface. Position the tape on the surface, starting at one end. Press down firmly as you apply, working along the full length to eliminate air bubbles.
5. Apply firm pressure. Use the heel of your hand or a roller to apply firm pressure along the entire tape length and across the full width. This seats the adhesive fully into the surface texture.
6. Seal the edges (recommended). Apply anti-slip tape edge sealer along the two long edges of the tape to prevent water ingress and lifting, particularly for external or wet-area installations.
7. Allow to cure. The tape can be walked on immediately, but full adhesive bond is achieved after 24 hours. Avoid heavy traffic or pressure washing for the first 24 hours.

Frequently Asked Questions

What is the difference between silicon carbide and aluminium oxide grit?

Silicon carbide (SiC) is harder than aluminium oxide (Al₂O₃) on the Mohs hardness scale and has sharper angular grain edges. This translates to better initial grip and longer service life before the grit wears smooth. Silicon carbide maintains its anti-slip performance in wet, oily and contaminated conditions where aluminium oxide may lose effectiveness.

How long does anti-slip tape last?

Service life depends on foot traffic volume and conditions. In moderate residential use, 3–5 years is typical. In commercial environments with heavy footfall, 1–2 years. Regular inspection and replacement of worn sections is best practice. For permanent, high-durability solutions, GRP nosings or GRP strips offer 10+ year service life.

Can I apply it to painted or varnished floors?

The adhesive bonds well to cured, hard-wearing paint and varnish. Apply primer first for best results. On freshly painted or soft-finish surfaces, allow the paint or varnish to fully cure before applying tape. Note that removing the tape from painted surfaces may lift the paint underneath — test a small section first if concerned.

Which width should I choose for stairs?

50mm is the standard choice for domestic stair tread nosing — it provides a clearly visible anti-slip strip without covering the majority of the step surface. 25mm suits narrow strips or when a more discreet appearance is preferred. 100mm provides fuller coverage across the tread for situations where maximum protection is required. 150mm covers almost the entire tread depth and suits environments where full-width coverage is specified.

Can I use this outdoors?

Yes. The tape is waterproof and UV stable, suitable for covered and exposed outdoor steps, ramps, decking and pool surrounds. For outdoor installations, edge sealer is strongly recommended to prevent water working underneath the adhesive from the exposed long edges. Apply at temperatures above +10°C for best adhesion.

How many stair strips does an 18.3m roll provide?

At a standard UK stair width of 860mm, an 18.3m roll provides approximately 21 strips per roll. A typical domestic staircase of 13 steps requires approximately 11–12 metres, so a single roll covers one complete staircase and provides spare for additional areas such as landings or external steps.

Does the surface need priming?

On smooth, non-porous surfaces (metal, tile, smooth concrete, painted surfaces) primer is not essential if the surface is clean and dry. On porous surfaces (rough concrete, brick, natural stone) or in high-moisture outdoor environments, applying anti-slip floor primer first significantly improves adhesion and prevents early lifting of the tape edges.

Can it be removed once installed?

The tape can be removed by working a flat-bladed tool under one edge and peeling carefully. Applying heat with a hairdryer softens the adhesive and makes removal easier. Some adhesive residue may remain on the surface, removable with adhesive remover or isopropyl alcohol. On delicate surfaces, test removal in an inconspicuous area first.
