Raffaele Lazzari

Product Specifications


Featuring a pebble-like, monolithic concrete form, Stone, designed by Raffaele Lazzari, is ideal for students to clamber over, lounge across, or perch on to eat. The enlarged scale adds an element of fun and plays with the imagination, perfect for a learning environment, whilst the softened curved form ensures there are no pointed corners for children to run into. Available in 3 sizes, Stone is made of precast concrete with stone aggregate in white, grey or dark grey colours for different looks. The smaller scale cousin of Moonstone is also ideally priced for smaller projects with less budget looking for a similar look.

Care Instructions

Precast Concrete
Remove any loose surface deposits with a brush.

Regularly wash the coating using a solution of warm water and non-abrasive, pH neutral detergent solution (with low wax content).

Thoroughly rinse the surfaces after cleaning to remove all residues. You can use a sponge, a soft bristle brush or pressure water cleaners. For pressure cleaners ensure you use cold or warm water and average pressure. Rinse after with fresh water and leave to dry.

Do not use abrasive sponges, discs, or brushes.

Do not use corrosive detergents, descaling agents, or acidic components (bleach, ammonia, vinegar, abrasive pastes).

For cleaning marks or solidified substances from the surface use slightly abrasive sponges for non-stick ceramic pans, accurately and lightly treat the parts to be cleaned as above. Please check with Botton + Gardiner for advice relating to cleaning special circumstances (i.e. stains from paint, acid, etc.) as required.

For surfaces prone to additional wear like that used for street furniture, regular treatment is recommended (at least every 2 years) with products containing high wax content. Evenly apply the product with a soft cloth and polish with a circular motion.

Avoid the products from being placed on surfaces subject to infiltrations or stagnant water puddles.

Additional Comments

Upon request, when technically feasible, it is possible to perform polishing operations.

The finished products are treated with a protective varnish, and upon request, anti-graffiti treatment can also be also applied.

This item can be ordered in a GRC - glass reinforced concrete finish for projects where weight is a concern for flooring surfaces or internal use (additional cost applies) and standard colours available.
