Description
Expo is the most economical Carobbio coping for a skimmer pool. The geometry repeats the Standard series – a straight element of 60 × 31.5 cm weighing 19 kg – but the surface is different: the marble grains are left exposed.
It is a good choice when you want a familiar classic shape at a reasonable price. There are five colours, and the range covers a short element, a right-hand and an inverted corner, as well as radius parts from 1.00 to 5.00 m.
Surface and profile
With the Expo finish the marble grains are clearly visible, and to the touch the surface is smoother than the sandblasted one. Towards the water the edge is 6.5 cm high and rounded – it keeps dust away and is comfortable to sit on. The slip-resistance class is A.
Strengths of the material
- Cool-touch structure: the stone stays comfortable for bare feet even in direct sunlight.
- Frost resistance: winter cold does not harm it.
- Reliable grip when wet, confirmed by testing to UNI EN 13451.
- Composition: reconstituted stone made of natural aggregates, selected marbles and pigments.
- Made in Italy with an eco-compatible approach and half a century of tradition.

Laying order
- First make a trial layout without adhesive and plan the cutting.
- The base should be stable, dry and well cured; install at 5 to 30–35 °C.
- Apply professional stone adhesive in a layer of about 1 cm.
- The gap between the individual pieces is about 1 mm.
- Grout with the special grout mix and immediately wipe the residue off the surface.
- If the pool is not finished, protect the coping with a cover until the works are complete.
Consumables and products
- One 25 kg bag of adhesive for coping and slabs covers approximately 27 copings or 20 slabs.
- Grout mix in a 25 kg bag (white, grey, pink, yellow, brick) covers ≈100 copings or 12 m² of slabs.
- Caroprotec sealer, 5 l: water and stain protection for ≈100 copings or 25 m² of slabs.
- Deter-AC (after laying) and Cibermac (seasonal) are sold in 5 l containers; each is enough for ≈100 copings.
- Additionally: Smacoil (local stains), Alganet (moss and algae) and Densorux (rust gel).
Maintenance over the years
The first wash is done after installation with a special cleaning product, and the water- and stain-repellent sealer is applied straight after it; without it the porous stone absorbs dirt. For maintenance over the years there are separate products for stains and for renewing the colour. We do not recommend a powerful water jet, strong chemicals or de-icing salt. The damp patches that are sometimes visible after opening the package are normal and disappear – the colour evens out in about six months.
Good to know
Because the raw materials are natural aggregates and pigments, the shade and surface may vary from batch to batch. When the paved area is over 16 m², mix slabs and elements from different pallets. Dimensions have a tolerance of ± 5 mm. Efflorescence – whitish and sometimes brownish traces – is usual for materials containing cement and washes off over time. The manufacturer replaces only a defective element that has not been installed, so check everything before you start work.
