The artificial grass a manufacturer tests in a laboratory in Valencia and the one that spends five summers on a roof terrace in Las Palmas do not live the same life. Three factors that are secondary on the mainland decide, here on the island, whether your turf is still green after eight years or turns pale grey after three and feels like an old carpet underfoot.
This guide explains what to look for on the datasheet, how the Canarian sun, the calima and the sea salt really affect the turf, and what maintenance it actually needs.
Once you have chosen a model, installation makes the difference: this is how we install artificial grass in Gran Canaria.
Factor 1: solar radiation (the most damaging)
Gran Canaria sits at the same latitude as the Sahara. The ultraviolet radiation an outdoor surface receives here is noticeably higher than almost anywhere on the Spanish mainland, and it acts all year round, not just in summer. UV breaks the polymer chains in the fibre: colour fades and the material turns brittle.
What to look for on the datasheet
- UV stabiliser compounded into the fibre, not applied to the surface. If the manufacturer does not state it, be suspicious.
- An 8 to 12 year colour warranty. It is the best indirect indicator of treatment quality: nobody guarantees a decade on a product that cannot take it.
- Polyethylene (PE) fibre for the visible yarn. Pure polypropylene degrades faster in the sun and feels stiffer.
Entry-level turf without serious UV protection is not cheaper: it is more expensive spread over fewer years.
Factor 2: surface temperature
This is the objection we hear most: "doesn't it get boiling hot?". Honest answer: yes, it gets hotter than natural grass, because it does not transpire. Dark artificial grass in full midday August sun can comfortably exceed 60 °C at the surface. Anyone telling you it stays cool is selling smoke.
What you can do is bring that down significantly:
- Choose lighter tones with a straw-coloured thatch. Dark greens absorb more radiation. An olive green mix with beige yarns can run several degrees cooler than a uniform deep green.
- Look for cooling fibre technologies (cool fiber, heat reflective and similar). Not magic, but the measured difference is around 10 – 15 °C.
- Hose it for 30 seconds before use. The temperature drops immediately and the effect lasts a good while.
- Use shade: a sail awning or a tree changes the equation completely.
- For play areas, consider a shockpad base, which also insulates thermally.
A practical note: in Gran Canaria this is a 3 or 4 hour a day problem in the hottest months. The rest of the time, with the trade winds, it is perfectly usable.
Factor 3: the calima (Saharan dust)
The calima leaves a very fine layer of Saharan dust on everything. On artificial grass that dust builds up between the fibres, mats the thatch and dulls the colour. It does not damage the material, but it looks bad if it is not removed.
What to do after a calima episode
- Wait until it has fully passed and the dust is dry. Wetting it during an active calima creates mud.
- Brush against the grain with a stiff synthetic-bristle brush (never metal).
- Rinse with a hose at low or medium pressure. Never a high-pressure washer: it lifts the silica sand and can break the seams.
- If marks remain, brush again once dry to lift the fibre back up.
Turf with good backing drainage (look for more than 60 l/min/m²) makes this much easier, because the water carries the dust downwards instead of pooling it.
Factor 4: sea salt
If you are on the front line — Las Canteras, San Agustín, Arinaga, Mogán, Bañaderos — the sea breeze leaves a constant salt film. The good news: salt does not attack synthetic fibre, unlike what it does to natural grass, metal or wood. That is one of the strongest arguments for artificial grass in coastal areas.
What does need care
- Rinse with fresh water every 4 – 6 weeks so the salt does not crystallise and leave a whitish bloom.
- Use stainless steel or plastic trims and pins. Ordinary galvanised steel rusts within months near the sea and stains the turf.
- Two-component polyurethane adhesive on the joints, not cheap self-adhesive tape: salty humidity lifts budget solutions.
How to read a datasheet in 60 seconds
Four numbers tell you what you are dealing with:
Fibre height (mm)
- 20 – 30 mm: high-traffic areas, walkways, small terraces, carpet-like look
- 30 – 40 mm: the sweet spot for gardens and terraces in Gran Canaria. Realistic and easy to maintain
- 40 – 50 mm: very plush and decorative, but flattens sooner under traffic
Density (stitches/m²)
Below 14,000 the backing shows through. Between 16,000 and 20,000 is the range that pays off. Above that, price rises faster than the visible improvement.
Total weight (g/m²)
Under 2,000 g/m² is low-grade product. 2,500 – 3,500 g/m² is the sensible benchmark.
Fibre type
Look for monofilament with a central spine ("C-shape"). The spine is what makes the fibre stand back up after being walked on. Fibrillated turf without a spine flattens and does not recover. Our three models — you can see them in the turf range — are chosen on these criteria.
Real maintenance (spoiler: it is low, but not zero)
- Every 4 – 8 weeks: brush against the grain in high-traffic areas
- Every 4 – 6 weeks on the coast: a fresh-water rinse against salt
- After each calima: brush and rinse
- Every 2 – 3 years: top up the silica sand if the model uses it
- With pets: remove solids daily and rinse the urine area 1 – 2 times a week. A fully perforated draining backing is mandatory here, not optional
Never do this: bleach, solvents, high-pressure washers at full power, a barbecue directly on top, or fixed planters left for long periods in the same spot (they flatten the fibre permanently).
Frequently asked questions
Does artificial grass fade in the Canarian sun?
Turf with a compounded UV stabiliser and a 10-year warranty does not fade noticeably. Low-grade turf without treatment does: it shows from the second or third summer, especially on south-facing areas.
Is it suitable for roof terraces?
Yes, and it is one of the most common uses in Las Palmas. The existing fall for drainage must be respected and drains must not be blocked. On roofs with delicate waterproofing it is laid unbonded, with perimeter ballast.
Do insects or weeds appear?
With a geotextile weed membrane under the base, practically none. The odd wind-blown seed may sprout at the edge and is pulled out by hand.
Does it stand up to the Gran Canaria wind?
Yes, if properly anchored: fixed perimeter, glued seams and silica sand as ballast. A badly finished installation can lift in exposed areas in the north and south.
Can I install it myself?
You can, on a small regular terrace. In a garden on soil, base preparation is 70 % of the final result and it is where nearly all DIY jobs fail: dips, wrinkles and visible seams.
Want to know which model fits your case?
At CanaryTurf we know the specific conditions of each area of the island and we work with models with reinforced UV treatment, designed for the radiation and sea breeze of Gran Canaria.
We come to your home with physical samples so you can see them in your own light and walk on them in the sun of your terrace, we measure the area at no cost or obligation and we tell you which model genuinely fits. You can book the free measuring visit here.
