Coo-Var Suredeck Anti-Slip Decking Protector is a clear, water-based acrylic anti-slip coating designed to protect exterior timber decking from slips, UV damage, mould, algae, and weathering — whilst preserving the natural wood grain and appearance. Unlike coloured decking paints that mask the timber, Suredeck's clear semi-gloss finish with micro-grip technology keeps decking safe underfoot without changing the look of the wood.

Developed by Coo-Var with over 115 years of British coating expertise, Suredeck provides proven anti-slip performance with a Pendulum Test Value (PTV) of over 35 — classified as low slip risk. The micro-grip clear coating creates a textured surface that significantly improves traction in wet conditions, reducing the risk of slips and falls on decking, balconies, poolside walkways, and timber steps.

For best results on tired, weathered, or greyed decking, revive the timber first with Lacq Turbogel before applying Suredeck. Turbogel restores the natural colour and condition of weathered timber, giving Suredeck the best possible surface to bond to and maximising the life of the protective coating.

Apply by brush or roller to clean, dry, prepared timber decking. Can be thinned up to 5% with clean water for the first coat on very porous or new timber. Coverage of 8–10 m² per litre from a 1 litre tin. Touch dry in 90 minutes, recoat after minimum 6 hours — making it possible to apply two coats in a single day. Full cure in 3–5 days.

Suitable for exterior tanalised, softwood, and hardwood timber decking. Clear finish only — preserves the natural wood appearance. Water-based, VOC ≤83 g/L, non-flammable, and low odour. Minimum application temperature 10°C.

Coverage: 8–10 m² per litre

Per Tin Coverage:
• 1 litre: Covers approx. 8–10 m² per coat

Coverage varies depending on timber porosity and condition. New, porous, or weathered timber will absorb more product. The first coat on very porous timber can be thinned up to 5% with clean water to aid penetration.

Example Calculations (two coats recommended):

Small Deck (up to 4 m²):
• Coverage needed: 8 m² (two coats)
• Product required: Approx. 1 litre
• Recommended: One 1 L tin

Medium Deck (up to 8 m²):
• Coverage needed: 16 m² (two coats)
• Product required: Approx. 2 litres
• Recommended: Two 1 L tins

Large Deck (up to 15 m²):
• Coverage needed: 30 m² (two coats)
• Product required: Approx. 3–4 litres
• Recommended: Three to four 1 L tins

For accurate project planning, measure your total decking surface area and allow for two coats minimum. Order 10% extra for surface variation and porosity.

Important: Touch dry 90 minutes. Recoat after minimum 6 hours. Full cure 3–5 days — avoid heavy foot traffic until fully cured.

Recommended System Products:
• Lacq Turbogel – Revive tired, weathered, or greyed decking before applying Suredeck for best results
• Paint Brushes • Paint Rollers • Roller Trays & Accessories

Important Safety Note:

Water-based, VOC ≤83 g/L, non-flammable, and low odour. Wear appropriate PPE including gloves and eye protection during application. Keep away from children and pets until fully cured (3–5 days).

⚠️ Important — Grooved Decking: Always use a brush on grooved decking. Do not use a roller on grooved decking — Suredeck must not be allowed to pool in the grooves as this will cause the coating to go cloudy. Rollers are only suitable for smooth decking surfaces.

Surface Preparation Sequence:

Step 1 — Revive Weathered Timber (if required):
• For tired, weathered, or greyed decking, apply Lacq Turbogel first to restore the natural colour and condition of the timber
• Follow Turbogel application instructions and allow to dry completely before applying Suredeck
• This step maximises the life and performance of the Suredeck coating

Step 2 — Clean the Decking:
• Sweep or brush away loose dirt, debris, and leaves
• Clean decking thoroughly to remove dirt, algae, mould, and contamination
• Use a suitable decking cleaner or pressure washer for heavily soiled surfaces
• Allow to dry completely — decking must be completely dry before and during application and curing phase

Step 3 — Sand if Required:
• Lightly sand smooth or weathered surfaces to open the grain and improve absorption
• Remove any loose or flaking existing coatings
• Wipe away dust and debris before application

Step 4 — Test:
• Test on a small, inconspicuous area first if the wood is heavily stained or has multiple old coatings
• Check for desired appearance and absorption before proceeding

Mixing & Thinning:

• Stir Suredeck thoroughly before use
• First coat on very porous or new timber: thin up to 5% with clean water to aid penetration
• Second coat: apply at full consistency — do not thin

Application:

• Apply in temperatures above 10°C for optimal drying and adhesion
• Do not apply to wet or damp timber, ensure dry throughout the curing phase.

Grooved Decking — Brush Only:
• Always apply by brush on grooved or profiled decking boards
• Work product evenly along the grain — do not allow product to pool in the grooves
• Pooling in grooves will cause the coating to go cloudy — apply thin, even coats
• Ensure complete coverage of all surfaces including the sides of grooves
• Coverage: 8–10 m² per litre per coat

Smooth Decking — Brush or Roller:
• Apply by brush or short-nap roller on smooth, flat decking surfaces only
• Apply evenly with consistent pressure
• Avoid pooling or overly thick coats
• Coverage: 8–10 m² per litre per coat

• Apply first coat and allow to dry for minimum 6 hours before applying second coat
• Apply second coat at full consistency
• Allow full cure of 3–5 days before heavy foot traffic

Drying Times (at 20°C):

• Touch dry: 90 minutes
• Recoat: Minimum 6 hours
• Full cure: 3–5 days (avoid heavy foot traffic until fully cured)

Drying times may be extended in cooler temperatures or high humidity.

What is Coo-Var Suredeck Anti-Slip Decking Protector and when should I use it?

Coo-Var Suredeck is a clear, water-based acrylic anti-slip coating designed to protect exterior timber decking from slips, UV damage, mould, algae, and weathering whilst preserving the natural wood grain and appearance. Use it when you need to improve traction on slippery decking and protect timber from weathering without changing the look of the wood.

How effective is the anti-slip protection?

Suredeck provides proven anti-slip performance with a Pendulum Test Value (PTV) of over 35 — classified as low slip risk. The micro-grip clear coating significantly improves traction in wet conditions, reducing the risk of slips and falls on decking, balconies, poolside walkways, and timber steps.

Will Suredeck change the appearance of my decking?

No — Suredeck is a clear semi-gloss coating that preserves the natural wood grain and appearance. It does not change the colour of the timber. The micro-grip texture is virtually invisible — your decking will look the same but feel much safer underfoot. Important: do not allow Suredeck to pool in the grooves of grooved decking as this will cause cloudiness — always use a brush on grooved decking.

Can I use a roller to apply Suredeck?

Only on smooth, flat decking surfaces. On grooved or profiled decking boards you must use a brush only — do not use a roller on grooved decking. Suredeck must not be allowed to pool in the grooves as this will cause the coating to go cloudy. Always apply thin, even coats with a brush on grooved decking.

What surfaces can I apply Suredeck to?

Suredeck is suitable for exterior tanalised, softwood, and hardwood timber decking. It is not suitable for composite, plastic, or non-timber decking surfaces, or for interior timber surfaces.

Should I prepare my decking before applying Suredeck?

Yes — decking must be clean, dry, and free from dirt, algae, mould, and loose coatings before applying Suredeck. For tired, weathered, or greyed decking, revive the timber first with Lacq Turbogel to restore the natural colour and condition before applying Suredeck. This maximises the life and performance of the coating.

How do I apply Suredeck?

On grooved decking: use a brush only — apply evenly along the grain and do not allow product to pool in the grooves. On smooth decking: apply by brush or short-nap roller. Stir thoroughly before use. The first coat on very porous timber can be thinned up to 5% with clean water. Allow minimum 6 hours between coats.

How long does Suredeck take to dry?

Touch dry in 90 minutes at 20°C. Recoat after minimum 6 hours — two coats can be applied in a single day. Full cure in 3–5 days — avoid heavy foot traffic until fully cured. Drying times may be extended in cooler temperatures or high humidity.

What is the minimum application temperature for Suredeck?

The minimum application temperature is 10°C — higher than many coatings. Do not apply in temperatures below 10°C or to wet or damp timber.

What coverage can I expect from Suredeck?

Suredeck provides 8–10 m² per litre. A 1 litre tin covers 8–10 m² per coat. Coverage varies depending on timber porosity — weathered or porous timber will absorb more product. Order 10% extra for surface variation.

How long before I can use my decking after applying Suredeck?

Touch dry in 90 minutes and recoatable after 6 hours. Allow full cure of 3–5 days before heavy foot traffic. Light foot traffic is possible after 6 hours but avoid heavy use until fully cured.

Is Suredeck eco-friendly and safe to use?

Yes — Suredeck is water-based, VOC ≤83 g/L, non-flammable, and low odour. Safe for use around children and pets once fully cured (3–5 days). Easy clean-up with water.

How often do I need to reapply Suredeck?

Reapply when the decking shows signs of reduced slip resistance or the coating shows signs of wear. Revive weathered timber with Lacq Turbogel before reapplying Suredeck if required. Always use a brush when reapplying to grooved decking.
