Stevensons-Stone® Finishes

Stevensons-Stone® mouldings are both versatile and durable. They can offer a thin section but are not brittle. They are lighter than stone or sand & cement products and therefore can offer significant construction savings.

Stevensons-Stone® mouldings have a Class Zero fire rating with reduced smoke density and toxicity characteristics. They offer superior water and stain resistance. They are acoustically dead. The mouldings are suitable for both exterior and interior use.

Stevensons-Stone® mouldings are impact resistant and their thinner section gives a reduced cladding zone. Their lighter weight requires less expensive metal support or fixing points than their heavier alternatives.

Stevensons-Stone® can be produced with a plain white ex-mould finish or it can be pigmented with any RAL or British Standard Colour. The material can offer a smooth or textured finish.

Jesmonite-based Stevensons-Stone® is a sophisticated variant of GRC and consequently shares characteristics of GRC manufactured products as set out in GRCA (Glassfibre Reinforced Concrete Association) Technotes. The GRCA Technotes confirm that good practice is consistent with:

• Acceptance that variation in colour and texture are to be expected (as with natural and cast stone). Samples, whilst useful, should not be taken as a guarantee that variations in colour and texture will not exist in the manufactured product.
• The manufacture and installation process may involve an element of damage as result of which repairs are to be expected. Good repairs should not be visible at a viewing distance of 5-6 metres in good daylight.
• Hairline cracks and surface crazing are a feature of GRC manufacture which is not prejudicial to the integrity of the casts as a whole. Assessment of surface blemishes and crazing should be made from a distance of 5-6 metres at right angles to the surface in good daylight.
