3 What is Granite? Granite is an igneous rock formed as a result of the slow crystallisation of molten magma at depth in the earths crust. Darker colours formed deeper in the earth than the lighter more crystalline colours and were thus cooled more slowly and are subsequently more stable (stronger) eg. Jet Black. Colours such as Baltic Brown formed closer to the surface and cooled quicker and exhibit bigger crystals which are weak points. Uplift and erosion has over millions of years resulted in this material outcropping at the surface (i.e. mountain ranges). The minerals that make up Granite are generally quartz, feldspar and various mafic minerals (amphiboles - a group of common rock-forming silicate minerals., pyroxenes a group of important rock-forming inosilicate minerals, micas reflectors in blue pearl and secondary materials. It is the size, distribution and precise chemistry of these minerals which give granite its colour

4 What is Granite? No two pieces of Granite are alike, each is totally unique. Granite is one of the hardest substances on earth with a rating of 7 on Moh s hardness scale (Diamond having a rating of 10!) Composition : Mica Feldspar Quartz

5 How is it manufactured?.. Granite is quarried in large blocks, typically measuring 3m by 2m. These huge rough cut blocks often do not give any indication of the beautiful Granite colour until polished. The material is rubbed, not cut, into scants (slabs) of uniform thickness by using a series of steel blades and steel shot (aggregate). This process can take between one and five days depending on the material density. The slabs are then highly polished on one side using a line polishing machine. A series of polishing heads holding in excess of 100 polishing pads create this finish. This is very difficult to replicate using hand held machinery or a CNC. Hence why recess drainers are duller in appearance

6 How is it manufactured?.. The worktops are then cut from the raw sheet material using one of our stone saws or the Combi Cut machine, currently the only in the UK. Once cut, the edge detail is applied using an edge polisher, then any cut outs or drainer grooves are added by the CNC machine. The worktops are then taken for hand finishing, QA checking and packaged ready for dispatch.

7 Technical Points to note The molecular structure renders Granite very stable and rigid, it will not bend or flex. Granite is not suitable in long span applications. Pitting and veining will occur in a random distribution of swirls, in addition, subtle variations in shade or areas of contrast are all common within Granite. Some level of what could be referred to as spots or blotches are inherent in the material. Small fissures are a common feature in any Granite and these natural flaws were present at rock formation. Baltic Brown, Giallo Veneziano and certain other lighter colours are resin treated at source to fill natural flaws and pit marks. Small scratches of less than 25mm in length are within tolerance and are considered acceptable.

8 Technical Points to note Due to the nature of Granite, the thickness of the worktops can vary slightly. Sheridan endeavor to keep this variation within a tolerance of +2mm. Granite is sometimes susceptible to blowing out. This occurs when contact is made with the material whilst cutting or grinding. This is very common in large particled Granite, Sheridan will fill and seal affected areas with epoxy resin, (color may vary) to ensure the material is not left with any sharp edges or chips Please note, drainer grooves are designed to create a vacuum release for items that are placed over the drainer area. Excess water that is retained over the drainer area and in the grooves themselves, needs to be wiped away as is the case with all sink drainers.. Tables should be referred to when planning for granite worktops: 1- aesthetics, 2- weight, maximum lengths with cut outs and upstands

12 Sheridan PLANNING OVERVIEW Think through the experience before you begin!

13 Joint positions.. Plan the worktop layout to ensure joints don t fall on or within 50mm of cutouts and cutouts are at least 50mm from the worktop edge. Wherever possible, joints in worktops should fall on a carcass end panel not in the middle, this gives additional support to a joint. Location of joints are determined at template stage. The number of joints will always be kept to a minimum where possible (please refer to table 2 above). Joints/notches are finished with a small arris to the top edge to remove sharp edges. Silicon sealant is applied to the joint below the arris to avoid water ingression. Arris Joint

14 Joint positions Where Sheridan are templating, all aspects below will be taken into consideration by the Sheridan templater Butt Joint required for double bevel and double pencil edge. 100mm min 100mm min Scribed Joint - required for Bullnose and Sharks Nose edge. Joints must be at least 100mm from sink or 120mm from hob cutout.

15 Joint positions.. Where Sheridan are templating, all aspects below will be taken into consideration by the Sheridan templater Joints above appliances are acceptable provided front and back support rails are fitted. Joints should never fall on sink or hob cutouts

16 Return Ends/Options.. Full/Part Return (for use against tall housing) Double Notch Internal Splay Triple Notch Single Radius External Splay Double Radius Breakfront Curved Breakfront

17 Sink / Hob Cut outs... Unpolished cut out (overmount/inset sink or hob cutout ) Undermounted polished sink cut out Tap hole Undermounted square polished sink cut out (less than 15mm radius corners) Polished Belfast cut out (Includes drip groove on underside)

18 Drainer Grooves... 5 Groove (1-5mm Slope) Leaf (1-5mm Slope) 5 Groove Angled (1-5mm Slope) Oblique Dogs Leg(1-5mm Slope) Fat with a 3mm recess) Note : Drainer grooves do not drain

19 Drainer Grooves... Drainer grooves and recessed drainers will be slightly duller than the surrounding worksurface, as they are machined after the slab has been polished Drainer grooves are designed to create a vacuum release for items that are placed over the drainer area. Excess water that is retained over the drainer area and in the grooves themselves, needs to be wiped away as is the case with all sink drainers...

20 Pan Rests... Pan rests are aesthetically pleasing and provide a solution to the problem of hot pans on worktops. Hot pans can cause thermal shock and / or scorching when placed on a granite and the consequences can be both dangerous and damage worktops. Pan rest are stainless steel Configuration is required on order Sizes are 200/300/400mm

21 Cut outs further notes.. Granite can expand by up to 1mm per metre. A gap of at least 3mm should be left at each end of the worktop when fitted, and filled with decorators caulk. Granite sink / hob cut outs are barred front & back (fitting of steel support bars to give additional support to cutouts), without steel support bars the length of a cut out is reduced considerably. Allow a minimum 50mm from the hob cut out or unpolished sink cut out to the front edge Allow a minimum of 120mm between heated cut outs Allow a minimum of 50mm from the polished sink cut out to the front edge

22 Cut outs further notes.. Allow a minimum of 70mm between sink cut outs Splash backs and upstands over 100mm must have a minimum gap from the face to the rear of the hob of: Electric 50mm, Gas 100mm If a waste disposal system is fitted to an undermounted sink additional support will be required. This must be addressed by the kitchen fitter/plumber not by Sheridan. Failure to add the additional support will invalidate the warranty. Additional support is required for ceramic sinks. This too, must be addressed by the kitchen fitter not by Sheridan.

23 Cut outs further notes.. Stainless Steel Sink Installation - Silicone sealant may be rendered ineffective when connecting taps and plumbing in the sink. It is important that the sink is resealed immediately after connection to avoid moisture ingression. This must be addressed by the consumers plumber. Failure to do so will invalidate the warranty

24 Edge Detail.. Double Bevel Double Pencil Full Bullnose Single Pencil Half bull Single Bevel Single Ovolo Imperial Sharks Nose* Ogee Birds Beak The edge detail can completely change the appearance of a worktop to suit the kitchen design. Edge detail may also be slightly duller than the worksurface. * Please note: this edge detail requires a minimum worktop width of 615mm (as opposed to 600mm).

25 Edge Detail.. An edge detail may be slightly duller than the worksurface. Bevel edges are hand finished and in some instances the material may chip when cut, this will result in a larger bevel being applied, which will be matched throughout the installation. Bull nose and sharks nose edge details will require a scribed (Masons mitre) joint. Apollo Granite joints are finished with a small arris to the top edge to remove sharp edges. Silicone sealant is applied between the two pieces to prevent water ingression, it s not used to fill the joint.

26 Overhangs.. Unsupported worktop overhang must not exceed 300mm. Maximum unsupported span between units is 600mm. For the rear edge, anything over 600mm requires a support baton fitted to the back wall. Standard overhang is 35mm from the carcass front, not the door. 35mm

27 Upstands.. 20mm Granite upstands are 20mm thick. 100mm Upstands are not normally cut from the same slab as the worksurfaces, therefore an exact colour match is not possible. Granite upstands are straight and rigid, gaps will be visible where there are variations in the wall profile. Plastering or tiling should ideally be completed after the worksurface installation. NEVER plaster between template and installation as this would ensure that the worktops don t fit.

28 Wall Cladding & End Panels Wall cladding will be manufactured in 20mm thickness material. The standard joint for Granite end panels will be a butt joint, ending with a 5mm overhang. A flush butt joint is available however unless requested we will always supply a normal butt joint. All end panels will be manufactured to the correct specified height, with no scribing allowance as the material is not easily scribed to the floor. Standard Butt Joint Flush Butt Joint

29 Handling & Size Limiting factors like access, stairs and service lift size should be taken into consideration with fragile nature of the tops. This will increase the number of joints required. For installations you will need to supply additional labour on orders which have worktops larger than 1.8m2 or weighing above 150kg. Every additional 75kg requires an extra person to assist with lifting. Sheridan can supply additional labour at an extra cost. The size of scant is a major factor in selecting the maximum usable length of a worksurface. Approximately 2.80m x 1.3m is the largest worksurface we are able to manufacture. This may be drastically reduced if you require a cut-out, especially in Granite with larger crystals. Due to the weight of Granite, please ensure that units are level and securely fixed before installation.

30 Damage Prevention Never place hot pans or cooking equipment directly onto the worksurface (or into an empty sink). Always use a heat protection pad or a trivet with rubber feet for hot cook wear or leave pans etc to cool on the hob first. Always use a chopping board. Apart from the effect that cutting on Granite has on blunting your knives, the surface is not scratch proof but is highly scratch resistant. Care should always be taken to protect your worksurface from sharp or heavy items. Care should be taken with exposed edges as if caught accidentally chipping can occur. In the event of this happening however, contact Sheridan as it is possible to repair small chips on edges or on the surface.

31 Care & Maintenance.. The Care & Maintenance instructions that are included in the kit should be read and followed to ensure the worktops continue to look as good as the day they were installed. Please ensure your keep these instructions for future reference. Your Care & Maintenance Kit contains all of the items required to help keep your new Worksurfaces in pristine condition. Please ensure you fully read and follow the safety instructions carefully before using the products in the care kit. Always wear rubber gloves when using chemicals to prevent any cracking, drying or other reaction to your skin.

32 Care & Maintenance.. What's in the Care Kit? Care & Maintenance instructions Stone Guard Disposable gloves Micro Fibre Cloth Stone Seal Stone Guard - is an anti-bactericidal surface cleaner specially formulated to tackle grease and grime leaving surfaces sparkling clean with a residual antibacterial effect. Stone Seal formulated for protection of Granite worktops. Protects against stains caused by food and drinks such as coffee and tea. One application will guarantee protection for long period of time (subject to proper maintenance).

33 Care & Maintenance.. Every day cleaning - Any spillage must be removed immediately, delay could case permanent damage. Granite must not be rubbed with abrasive materials. For normal day to day cleaning, wipe the worksurface with a damp cloth and the Stone Guard, rinse with warm clean water and dry with a lint free cloth. Wipe the worksurface, with a damp cloth and the Stone Guard cleaner to remove any oils and fat. Buff dry with a soft white cloth. Persistent stains - If any stains need further attention, allow the Stone Guard 30 seconds contact time before wiping and rinsing.

34 Care & Maintenance.. Sealing Granite Granite worktops are sealed during manufacture and upon installation, they should then be sealed every 6 months using Stone Seal supplied in the Care & Maintenance kit. To test if a worktop requires resealing, apply a drop of water to the surface, if the water runs away, the seal is ok, if the water forms a pool, it requires sealing.
