When you receive your product you may notice minor scuffing on the surface. This can occur due to movement in transit and will generally disappear in time.
Block paving colour swatches
Colour variations can occur within packs, therefore:
Ensure your sample and block are from the same factory. Block paving should be ordered from the same batch number to avoid colour variation. Do not mix blocks from different factories. Bradstone cannot accept responsibility once blocks are laid from different batches. Best results are achieved through mixing from 3 to 5 different packs and from vertical columns rather than horizontal rows.
We recommend a neoprene faced or rubber sole plate on vibrating plate compactors to reduce scuffing. Light colours are susceptible to staining and care should be given when selecting blocks for driveways.
Natural stone colour and maintenance
Natural stone products will have variations in colour and texture within single pieces and from piece to piece. We recommend a reasonable amount of product is viewed at your local stockist before ordering. Natural stone products may contain minor imperfections. Product should be mixed from a number of packs prior to installation. We strongly recommend that natural stone is always laid on a full mortar bed. Natural stone needs to be handled very carefully when installing to minimise staining and we would advise that Smooth Natural Sandstone, Fine Grained Natural Sandstone and Grand Natural Sandstone be sealed prior to laying. However, if this is not possible, it should be covered up as it is installed and sealed as soon as it is laid.
The Silver Grey colour in all our Natural Sandstone products will vary with differing geological conditions. Such variations can lead to small particles of ironstone within the product creating a darkening of the surface with natural weathering. Being pale in colouration, this natural weathering is more obvious with Silver Grey compared to other natural products in the Bradstone range.
Slate has many natural characteristics, therefore, care should be taken when laying to aid/enhance the overall finished aesthetic appearance. In most cases this paving has more than one usable face, we strongly recommend the following checks be made:
• Select the best finished top surface to work with ensuring it is free from calcite mineral deposits
• Choose the desired shade variation to compliment the surrounding paving
• Dry lay the paving prior to final installation/fixing.
Manufactured from the finest raw materials, under strict controls allows us to obtain the exceptional technical characteristics of full-body unglazed porcelain paving: high bending resistance (>2000 N), high resistance to surface wear (<145 mm3), to freezing and chemical attack, with a water absorption level of <0.1% in a wide range of finishes and colours.
Anti-slip surface resistance
• Mode Textured = Class 3 / R12 / Group C
• Mode Profiled and Aspero = Class 2 / R11 / Group B
• All other porcelain paving = Class 3 / R11 / Group C
For traditional fixing, only pointing mix/grouts for porcelain paving should be used. We recommend Bradpoint jointing compound for this. Do not use white cement nor materials containing black pigments. Finishes are intentionally manufactured with slightly uneven colour tones and surface decoration, these subtle variations set these products apart.
Fired to incredibly high temperatures during manufacture Porcelain paving has extremely low water absorption values which makes them inherently strong and exceptionally durable. The use of a slurry primer to the reverse of each paver is both essential and more importantly critical to the overall performance of Bradstone porcelain paving. We recommend the use of Bradstone Bradbond for this. Applied to the underside using a stiff brush, it provides an exceptional bond between paver and the wet fully compacted cementitious bedding mix underneath. Mixed to manufacturer’s instructions and applied with care it forms an immediate bond which prevents the pavers from lifting or potentially moving in the future when correctly laid.

Bradstone porcelain paving can be easily cut on site and mostly to any size. All you need is a hand held saw with a power cut off facility, fitted with a good quality diamond blade suitable for porcelain pavers/tiles.
Ensure the blade is water fed to reduce the amount of dust given off, score the product on low power first, then wet it and cut through. Scoring the product first will help to alleviate the potential risk of edge/surface chipping.
Bradstone porcelain paving can easily be cleaned by applying an acid based cleaner diluted to the manufacturer’s instructions. In fact, we strongly recommend the finished laid area be thoroughly cleaned/washed down which helps remove general building dirt, grout residue and any grease deposits that may be present. It is also recommended that periodic cleaning with a porcelain cleaner will help to keep the paving looking its best.
Dependent on the type of stain/surface residue present (i.e. suction marks, grease, grout, general building site dirt) there is a wide range of off-the-shelf specialist cleaners available. Always check the manufacturer’s instructions first before applying to any test area.
Concrete paving colour
Colours may vary subtly, especially in weathered shades. Colours will appear different during varying weather conditions such as sunlight and rain. Please check colour samples in dry conditions and in full daylight. Where possible, products should be selected from the same product batch. Occasionally dark and light patches may occur on the surface of the paving. This is due to differential weathering where the surface of the paving has cured at different rates. All decorative products will weather and change appearance over time.
Efflorescence appears on concrete paving products as white patches or a lightening of the surface colour, but seems to disappear when wet. It is formed by a normal chemical reaction between cement and water which causes calciumhydroxide (lime) to migrate through damp concrete to the paving surface and then react with carbon dioxide in the atmosphere resulting in a deposit of calcium carbonatecrystals. Efflorescence is very unpredictable in its occurrence but is more prevalent in winter when concrete becomes wet and dries more slowly.
Although there are cleaners available, efflorescence is a natural phenomenon and will generally disappear with the natural weathering process and the passage of time. Aggregate Industries cannot accept responsibility for the effect of efflorescence which can be a characteristic of all good quality products with a high cement content.
Weathering and site conditions can occasionally cause other variations in shade to appear. Differential weathering can cause patchy dark discolourations on the surface of individual units. Again this will generally diminish over time and will not affect long term performance. Natural stone may develop added marking, deposits or patches as mineral content oxidises. All products can develop algae and organic growths under certain environmental conditions and may require cleaning. Areas adjacent to borders, plant pots and trees may discolour from transfer of plant life; specialist maintenance advice may need to be sought.
Aggregate Industries cannot accept responsibility for any of the above conditions. Should you require further advice in this specialist area call our customer care team on 01335 372289.
