Cast Stone Products: Top Ten Installation Tips

Marketing ALL, Cast Stone Leave a Comment

Installation of cast stone can be very tricky given the nature of the product. It goes without saying that care must be taken when handling cast stone products. Here are some great tips for handling and installation of our cast stone products, but for more information download our cast stone brochure or contact the cast stone team.

Store pallets safely

After receipt of items, it is best practice to avoid storing pallets on top of each other to ensure the products on the lower units are not damaged.

Manual handling

Units must be supported by two bearers positioned approximately 25% in from each end. A manual handling assessment must be carried out before the product is moved.


Cast stone fixings

Cast stone fixings are available to help with the installation of all cast stone products.

Installation of all architectural dressings should be in accordance with BS 5628 Part 3; 2005, or as detailed on our drawings.

Colour recommendations

For colour recommendation please consult mortar manufacturers’ tables. It is recommended that trial mixes should be used in sample panels prior to the commencement of construction.


Cast stone head

With cast stone heads, a suitable cavity tray should be provided.

Over openings in external cavity wall construction, a suitable stepped cavity tray with stop ends should be provided (projecting a minimum of 150 mm beyond each side of the opening) to direct water outwards, via weep holes, where appropriate.


Cills or subcills should be provided with D.P.C. for the full length and width of the cill bed, turned vertically upwards to cover the interior side of the cill as far as the window board or use a cavity tray with stop ends.


Before pointing, suitable masking tape should be fixed to either side of the joint to protect the stone from mortar stains. We recommend for both pointing and repair that trials are carried out on samples to confirm colour and material suitability prior to general application.


Cast stone samples

Colour testing trials are recommended. We have four colours, and colour sample kits are free to order.

Once in position components should be protected as far as possible from mortar spillages and accidental damage by following trades. Projecting features, cills in particular, must be protected, preferably with a rigid cover.


No attempt at cleaning the cast stonework should be made without prior consultation with the manufacturer as this may lead to irreparable damage.


Efflorescence is a natural phenomenon which can manifest itself as a white powder or as an apparent lightening or fading colour.
