FAQ’s

Q  -  What is the Slip Resistance Value ( SRV ) of a terrazzo tile ?

A  -   Standard terrazzo tiles would normally achieve an SRV of approx. 65 in the dry and 35 to 36 in the wet when ground on site to a standard 80.s grit finish.  For more sensitive areas this can be increased to approx. 38 in the dry and 45 in the wet by incorporating anti-slip additives in to the tile matrix.  Terrazzo tiles would normally be tested using the ‘Pendulum’ method and Quiligotti have in house testing facilities which can test production tiles prior to despatch.

 

Q  -  Can terrazzo tiles be used in external areas ?

A  -  Yes, but Quiligotti would recommend the use of tiles containing anti-slip additives in these locations to enhance the Slip Resistance of the tiles.  Alternatively, Quiligotti can manufacture tiles from their ‘Slip Resistant’ Range which contain anti-slip additives and produce a textured finish more suitable for external use.  These textured finish tiles would be fixed ‘laid-only’ to maintain the finish, and not ground and polished to a smooth finish.  In both cases, the sub-base would need to be solid ( tamped concrete preferably ) to receive the tiles and bedding.

 

Q  -  What bedding and bed thickness do you recommend for installing terrazzo tiles ?

A -  Terrazzo tiles are normally fixed on to a light tamped concrete sub-base using a semi-dry 1:3-4 cement:sand screed with the tiles and bedding being laid at the same time.  A finishing zone for tile and bed of approx 75mm would normally be ideal but based on using a 28mm thick tile the general parameters would be between 50 – 100mm for a ground bearing slab. 

 

Q  -  What sized tiles can you make ?

A  -  The standard sized tile ( and most economical ) manufactured by Quiligotti is 300 x 300 x 28mm.  Other non-standard sizes which can be produced are as follows : 

297 x 297 x 28mm

397 x 397 x 33mm

400 x 400 x 33mm

497 x 497 x 38mm

500 x 500 x 38mm

597 x 597 x 42mm

 

Q  -  How many tiles can you get on a pallet / wagon ?

A  -  A pallet of standard 300 x 300 x 28mm tiles contains 216 No tiles ( 19.44m2 ) and weighs approx 1300kg.  A full wagon would typically be 20 pallets (  389m2

 

Q  -  Do you need any specialist joints in a terrazzo floor ?

A  -  You would normally fix an expansion joint in the terrazzo floor to mirror any joints in the concrete sub-base.  The type of joint would depend on the anticipated movement ( to be determined by the Structural Engineer ).  If there are no joints in the concrete and the floor area is larger than approx 6m x 6m it would be normal to incorporate rigid crack inducer strips in to the floor to divide the floor up into sensible bay sizes.  A perimeter isolation joint would normally be formed at the junction with walls using polystyrene or similar say 6mm wide.

 

Q  -  Can you supply precast terrazzo items such as skirting, steps etc ?

A  -  Quiligotti can supply precast terrazzo items if required.  Enquiries should be directed to the Sales Office who would be able to provide a quotation subject to receipt of the relevant information regarding quantities, sizes etc.

 

Q  -  Can we have samples of the tiles manufactured by Quiligotti ?

A  -  Quiligotti can provide samples of tiles from standard ranges generally within a few days.  For bespoke samples which need to be made, you should allow a period of approx 1 week.  Typically samples are sent out in a 150 x 150 x 28mm format by carrier.

 

Q  -  Do Quiligotti have tiles readily available in stock  ?

A  -  Generally Quiligotti manufacture tiles to order.  However, there are always tiles available from stock in various colours and quantities which are ready for immediate order / despatch.  Once a customer confirms colours and quantity needed,  Quiligotti can advise what is available and provide samples where required.

 

Q  -  How do you clean terrazzo floors ?

A  -  Terrazzo is very cost effective and easy to clean and maintain.  Ongoing cleaning of terrazzo floors is normally carried out using only warm water and a neutral detergent ( PH7 ).  For detailed information on cleaning contact our Sales Office and we can send you are full recommendations for Cleaning and Maintenance of terrazzo floors.

 

Q  -  What colours can terrazzo tiles be made in ?

A  -  A very large number of different coloured tiles can be produced by using various combinations of the different  pigments and aggregates which are used by Quiligotti.  Bespoke samples can be produced where required and Quiligotti would endeavour to try and match existing terrazzo floors with the materials they have available.

 

Q  -  Can terrazzo tiles be laid when using an underfloor heating system ?

A  -  Terrazzo tiles can be laid in conjunction with underfloor heating systems but the method of installation would be dependent on the type of underfloor heating being installed to determine the best method of laying the tiles.

DRAWINGS & SPECIFICATIONS CARE & MAINTENANCE

Terrazzo floors are practical, hard wearing and very easy to clean. To maintain their pristine appearance, Quiligotti recommends the following simple steps to a beautiful, long lasting floor.
 
DAY TO DAY CARE
Stains should be removed as soon as possible before they dry out. Stubborn areas of dirt caused by sticky sweets and chewing gum should first be removed with a palette knife or similar utensil. Loose dirt and debris should be swept with a large, soft broom or ideally a 'v' shaped scissor mop. Floors should be scrubbed using a solution of clear water and neutral (pH7) cleaning agent mixed strictly in accordance with the manufacturer's instructions. A two tank machine should be used - one for clean water and one for picking up soiled water. If this is not available, cleaning water should be changed regularly to ensure complete removal of dirt. Best results are obtained using automatic scrubbing pads which must be cleaned and checked regularly to prevent damage to the surface of the floor. Terrazzo floor can be polished or burnished to enhance the shine using a high speed polishing machine and a red polishing pad.
 
Acids and alkaline-based cleaning agents should not be used as these may damage the floor surface or destroy the cement base. High soap content cleaning agents or waxing the floor may cause the floor to become slippery so these should be avoided. Use of disinfectants is not recommended as these may stain the tiles.
 
Neutral cleaning agent (pH7) should be used to clean your Terrazzo floor. Use of incorrect cleaning products, or lack of correct maintenance may damage the floor, causing pitting or damage to the cement grout in the joints.
 
NEVER use metallic brushes or wire wool pads as these will damage the floor surface. ALWAYS USE NEUTRAL (pH7) CLEANING DETERGENT
 
LONGER TERM MAINTENANCE
Quiligotti does not recommend surface sealing or waxing of terrazzo. This is because the seal can wear differentially, particularly in areas of heavy foot traffic, causing an unsightly finish. Removal of these surface sealers can potentially damage the finish of the floor. At the time of installation a penetrating sealant case hardener, such as Lapidolith, is normally applied immediately after polishing to seal off the pores and improve resistance to staining.
 
REFURBISHMENT
Terrazzo floors are renowned for their durability and with proper care will outwear most other flooring materials. Unlike other surfaces, after many years of use, terrazzo's good looks can be restored if required by re-grinding and re-polishing the floor, returning it to pristine condition.
