Extreme Paints Anti-Slip Decking Paint is a water-based exterior timber paint for prepared softwood, hardwood and sound previously painted wooden decking. Its satin finish adds colour while helping protect decking boards from weathering, UV exposure and everyday foot traffic.

Base paint and separate silica anti-slip additive are supplied. Mix the complete supplied additive thoroughly into the paint before application, then stir periodically to keep the grit evenly distributed. The resulting textured finish provides additional grip; it does not make wet, icy or contaminated decking slip-proof.

Use on properly prepared timber decking, wooden steps, verandas and walkways. Remove algae, moss, grease and loose coatings before painting, allow the timber to dry and test compatibility on previously treated surfaces. Not suitable for composite decking.

The application is straightforward:

Apply the anti-slip paint by brush or roller; do not spray paint mixed with silica grit. Apply two thin, even coats, avoiding pooling in grooves and between decking boards. Keep the additive evenly suspended with periodic stirring, and protect the fresh coating from rain during early curing.

Suitable Substrates:

Softwood and hardwood decking boards (new or previously coated, once clean and sound)
Exterior wooden steps, verandas, handrails, and garden furniture
Prepared masonry and concrete slabs where a uniform satin finish is desired

Not suitable for composite decking. Always test a small, inconspicuous area on unfamiliar surfaces.

Coverage & Spread Rate:

6–8 m² per litre per coat, dependent on timber porosity and profile (grooved boards absorb more).
Two thin coats are recommended for full weatherproof protection, colour depth, and slip-resistant performance.

Pack size	Per coat	With two coats
5L	30–40 m²	15–20 m²
10L	60–80 m²	30–40 m²
20L	120–160 m²	60–80 m²

Coverage is approximate and depends on timber porosity and profile. Rough or grooved boards may require more paint.

Drying & Curing Times (@ 18 °C):

Touch dry: 2–4 hours
Recoat: 2–4 hours
Light foot traffic: ~8 hours
Full use: 24 hours
Full weatherproof cure: 7 days
Cool, damp, or shaded conditions will extend drying; protect fresh coatings from rain during early cure.

Storage & Clean-Up:

Store between 5–30 °C in frost-free conditions. Reseal firmly between uses. Clean brushes and rollers with warm, soapy water while the paint is still wet; no harsh solvents required. During peak demand, plain tins may be supplied; product quality is identical.

Safety Notice:

This water-based, low-VOC outdoor coating should be applied with adequate ventilation. Avoid skin and eye contact and keep out of reach of children and pets until fully dry. For PPE guidance and full safety information, consult the product Safety Data Sheet (SDS).

Note:However, please bear in mind on some occasions the packaging may arrive slightly damaged. Please do not order if you won't be satisfied with this.

For correctly prepared exterior timber decking, wooden steps, verandas and walkways. Base paint and a separate silica anti-slip additive are supplied; mix the complete additive into the paint before application. The textured satin finish provides additional grip, but does not make wet, icy or contaminated decking slip-proof. Not suitable for composite decking.

Suitable for domestic and commercial timber decking where a coloured, weather-resistant coating is required. Test compatibility with existing coatings or timber treatments before painting.

Unlike a penetrating decking oil, this paint forms a coloured surface coating. Good preparation and ongoing cleaning and maintenance are important for performance.

Application Instructions

Surface Preparation
Clean the decking thoroughly to remove algae, dirt, moss, grease, and any loose or flaking coatings. Ensure timber moisture content is below 18% before application. Sand glossy or weathered areas back to a matte key to ensure proper adhesion.

Mixing
Stir the paint with a paddle mixer for at least 2 minutes until uniform. Slowly add the complete supplied silica additive while stirring, ensuring even dispersion. Stir periodically during application to keep the grit evenly suspended.

First Coat
Apply a thin, even coat using a brush or roller, following the grain of the timber. Take care to avoid puddling in grooves or between decking boards.

Second Coat
After 2–4 hours at 18 °C, apply a second thin coat at right angles to the first pass. This ensures complete coverage, consistent colour, and a strong weatherproof film.

Application Method
Apply the anti-slip paint by brush or roller only. Do not spray paint mixed with silica grit, and stir periodically to keep the additive evenly suspended.

CuringProtect freshly coated surfaces from rain or moisture for a minimum of 6 hours. Allow 8 hours before light foot traffic, 24 hours before replacing garden furniture, and 7 days before the coating reaches full weatherproof performance.

Frequently Asked Questions

What surfaces can I apply Anti-Slip Decking Paint to?

Use on correctly prepared exterior softwood and hardwood timber decking, wooden steps, verandas and walkways. The timber must be clean, dry, sound and free from algae, moss, grease and loose coatings. Test compatibility with previous treatments before painting. Not suitable for composite decking.

Can Anti-Slip Decking Paint be used outdoors in all weather?

The cured coating is designed for exterior timber and offers UV and weather resistance. Apply in suitable dry conditions, ideally between 10°C and 25°C, and protect the fresh coating from rain during early curing. Cool, damp or shaded conditions extend drying times.

Does Anti-Slip Decking Paint provide anti-slip protection?

Yes. Base paint and a separate silica anti-slip additive are supplied. Mix the complete supplied additive thoroughly into the paint before application and stir periodically to keep it evenly distributed. The textured finish provides additional grip, but wet, icy or contaminated surfaces can still be slippery.

How does Anti-Slip Decking Paint compare to decking oil?

Decking oil penetrates timber and requires frequent reapplication, while this product forms a durable protective coating on the surface. It offers longer-lasting colour, stronger UV protection, and enhanced anti-slip performance compared to traditional oils.

What's the expected lifespan of Anti-Slip Decking Paint in UK climate?

Service life depends on timber condition, preparation, application, traffic and weather exposure. Inspect the decking regularly, keep it clean and apply maintenance coats when the finish begins to wear. A fixed lifespan cannot be guaranteed.

Is primer needed before applying Anti-Slip Decking Paint?

A separate primer is not usually required as this product is self-priming. On bare or porous softwoods such as pine and cedar, a thinned first coat improves adhesion and gives more even sealing, while hardwoods can usually be painted directly after proper cleaning and degreasing.

How many coats of Anti-Slip Decking Paint are recommended for best results?

Two coats are recommended for most surfaces, while high-traffic areas such as steps and ramps may require three coats for maximum durability and consistent anti-slip performance.

Can Anti-Slip Decking Paint be sprayed for faster application?

Do not spray the anti-slip paint after mixing in the silica additive. Apply by brush or roller and stir periodically to keep the grit evenly distributed.

How much coverage can I expect from Anti-Slip Decking Paint?

Coverage is approximately 6–8 m² per litre per coat on smooth surfaces and 5–7 m² on rough or porous timber. As a guide, a 5L tin covers around 30–40 m² per coat and a 20L tin approximately 120–160 m² per coat; for a full two-coat system, coverage is roughly half these values.

How should I clean tools after using Anti-Slip Decking Paint?

Clean brushes, rollers, and equipment with warm soapy water immediately after use, as this is a water-based product. Dried paint may require specialist cleaning solutions.

Is Anti-Slip Decking Paint pet-safe once dry?

Keep children and pets away during application and curing. At 18°C, touch drying is around 2–4 hours, light foot traffic around 8 hours, full use around 24 hours and full cure around 7 days. Cooler or damp conditions extend these times. Follow the product label and Safety Data Sheet before returning the area to use.

Is Anti-Slip Decking Paint low-odour and environmentally safe?

It is a water-based, low-odour coating. Apply with adequate ventilation, avoid skin and eye contact and follow the product label and Safety Data Sheet. Do not allow paint or wash-water to enter drains, ponds or watercourses.
